INTRODUCCIÓN

Antecedentes

La automatización de Subestaciones es desde la aparición del IEC 61850 mas que solo

la automatización de equipos. Es uno de los primeros pasos para la creación de un

altamente confiable sistema de potencia que responda rápidamente a los eventos en

tiempo real con apropiadas acciones y que soporte el planeamiento y administración

necesaria para un costo efectivo en las operaciones. La automatización no es

simplemente el reemplazo de procedimientos manuales mas bien debe permitir al

Sistema de potencia operar de una forma basada en la precisión de la información en el

momento oportuno.

En el pasado la atención de las empresas eléctricas estuvo enfocada solo en la

administración de la infraestructura del sistema de potencia. Sin embargo el mundo ha

cambiado, ahora hay 02 infraestructuras que deben ser administradas: La infraestructura

del Sistema de Potencia y la Infraestructura del Sistema de Comunicaciones.

La automatización de Subestaciones tal como la presenta la IEC 61850 no estuvo

disponible hasta hace algunos años atrás debido a que las comunicaciones no estuvieron

disponibles para soportar las aplicaciones que en ese entonces se requerían. Por lo tanto

uno de las principales habilitadores para que se logre la automatización de subestaciones

fue reconocer que el cableado extenso entre los equipos en patio de llaves y la sala de

control se podrían eliminar con la aplicación de la tecnología Ethernet . Hoy en día el

desarrollo de las comunicaciones hace posible que las aplicaciones hasta ese entonces

soñadas se efectúen.

Otro de los principales habilitadores es el avance de la tecnología digital que logro que

los tradicionales equipamientos como medidores, relés de protección y Unidades

Terminales Remotas (UTR) hayan adquirido nuevas características y funcionalidades,

una de ellas es la capacidad de "hablar un lenguaje" (protocolo de comunicación) a fin de

entregar toda la información valiosa que disponen.

Objetivos del Informe

El informe tiene por objetivo presentar las nuevas tendencias mundiales relacionadas con

la automatización de Subestaciones de potencia las mismas que deben ser tomadas en

consideración en todo nuevo proceso de automatización de Subestaciones

fundamentalmente aquellas que se efectúan bajo la Norma IEC 61850.

Se presenta la Norma IEC 61850 como uno de de los primeros pasos para la creación de

un altamente confiable sistema de potencia que responda rápidamente a los eventos en


necesaria para un costo efectivo en las operaciones.

Se indica además como la implementación de la Norma IEC 61850 conduce a la

formación de la red inteligente empresarial el cual traería muchos beneficios a las

diferentes áreas de la empresa eléctrica.

Estructura del Informe

Finalmente se presentan las principales conclusiones del informe.

CAPÍTULO 1

ESTANCARES INTERNACIONALES ACTUALES Y TENDENCIAS INDUSTRIALES DE AUTOMATIZACION DE SUBESTACIONES DE POTENCIA

1.1 Introducción

Este capítulo describe los estándares internacionales actuales asociados a la

automatización de Subestaciones de Potencia y las nuevas tendencias industriales

usadas como referencia en la planificación y desarrollo de las nuevas arquitecturas de

automatización de Subestaciones.

1.2 Estándares Internacionales actuales

El avance de la tecnología digital y las comunicaciones en los equipos utilizados en las

Subestaciones Eléctricas han traído como consecuencia la necesidad de nuevos

estándares.

1.2.1 Operación de Equipos de Comunicaciones en Subestaciones Eléctricas :

IEEE 1613 e IEC 61850-3

Hoy en día existen 04 estándares IEEE desarrollados por el Power Systems Relaying

Commitee PRSC del IEEE dirigidos a la operación de los relés de protección en las

Subestaciones Eléctricas

• ANSI/IEEE C37.90-1989 IEEE Standard for Relays and Re/ay Systems

Associated with Electric Power Apparatus: Défine las condiciones de servicio ,

niveles de tensión, rangos de temperatura , humedad y los requerimientos

dieléctricos y capacidad de soporte al impulso de los relés de protección.

• IEEE Std C37.90.1-2002™ IEEE Standard for Surge Withstand Capability (SWC)

Tests for Relays and Re/ay Systems Associated with Electric Power Apparatus:

Define la capacidad requerida para soportar los transitorios sin daño o falsa

operación.

4

• C37.90.2 -2004 IEEE Standard for Withstand Capability of Re/ay Systems to

Radiated Electromagnetic lnterference from Transceivers: Define los

requerimientos de inmunidad para la operación de equipos de comunicaciones

personales (walkie-talkies) en ambientes cercanos a los re/es .

• IEEE C37.90.3 Standard Electrostatic Discharge Tests for Protective Relays:

Define los requerimientos de inmunidad de los relés de protección para

transitorios debido a baja humedad y tensiones de descarga estática.

Dado que hoy en día se utilizan muchos equipamientos de comunicaciones tales como

Switches y Routers en el ambiente en donde operan los relés de protección

(Subestaciones Eléctricas) dichos equipamientos deben tener el mismo o superiores

requerimientos de performance que los relés de protección

Es asi que el Grupo de trabajo C2TF1 del IEEE Power Engineering Society Substations

Committee elaboro el Estandard IEE1613 Standard Environmental and Testing

Requirements for Communications Networking Devices in Electric Power

Substations el cual provee nuevos criterios para las pruebas de equipos en las

Subestaciones. Básicamente el estándar indica que los equipos de Networking deben

cumplir similar o superiores condiciones de prueba que los reles de protección. El

estándar define condiciones de servicio, condiciones ambientales y valores de prueba

para modems, firewall, Routers, Switches y todo equipamiento de Networking dentro de

Subestaciones.

La norma IEE 1613 define 02 tipos de clase de performance:

PERFORMANCE CLASE 1 : Es para equipos usados para propósitos generales dentro

de una Subestación donde perdidas temporales de comunicación y/o errores de

comunicación pueden ser tolerados durante la ocurrencia de un transitorio.

PERFORMANCE CLASE 2 : Es para equipos usados dentro de subestaciones donde se

desea ningún error en los equipos de comunicaciones ante la ocurrencia de un transitorio.

La Performance Clase 1 es el mínimo requerimiento del IEE 1613, la performance Clase

2 no es mandataria y es una opción que puede ser usada por un fabricante o empresa

eléctrica.

Para cumplir con los requerimientos de Performance Clase 2 es necesario tener Fibra

óptica . Las fuentes de poder internas de los equipos tendrían que ser blindadas para que

dichos transitorios no lleguen a las fuentes de poder.

Similar al IEEE 1613 la norma IEC61850 también define requerimientos ambientales para

equipos de comunicaciones dentro de una Subestación. Este Estándar esta dividido en

5

1 O partes el cual ofrece un marco completo de pruebas incluyendo EMI (Interferencia

Electromagnética), requerimientos de inmunidad y medioambiente (IEC 61850-3).

1.2.2 Protocolos de Comunicación

Los protocolos de comunicación es el "lenguaje de los IEDs". Son un conjunto de reglas

que permiten que 02 equipos intercambien información. A continuación se describe los

protocolos de comunicación de mayor uso en el ambiente eléctrico:

DNP3 SERIAL Y DNP3 LAN

DNP es basado en los estandards de la IEC Technical Commitee 57, Working Group 3

quienes trabajaron en la estandarización de un protocolo de 3 capas OSI llamado

"Enhanced Performance Architecture" (EPA) que es un protocolo para telecontrol. DNP

fue seleccionada como una práctica recomendada del IEEE C.2 task Force como

protocolo recomendado para unidades terminales remotas

DNP 3 es un protocolo de adquisición de datos utilizado por las compañías eléctricas, gas

y agua . Es diseñado como un abierto, interoperable y simple protocolos para Sistemas

Scada . Usa la interrogación Maestra/Esclava para enviar y recibir información.

DNP 3 es un protocolo de 03 capas ( Capa física, Enlace de Datos y Aplicación) . Provee

multiplexación, fragmentación de datos , corrección de errores, priorización . DNP 3

ofrece las siguientes importantes características:

• Transferencia de archivos

• Capacidad de soportar 65520 equipos

• Sincronización de tiempo y estampando de eventos

• Mensajes tipo Broadcast

• Confirmación en la capa de enlace de datos y Capa de aplicación

6

La capa de aplicación es basada en objetos y se cuenta con una lista extensa de objetos

funciones y formatos para el que pregunta como el que responde. La Capa de enlace de

datos provee métodos de conseguir la información tales como POLL-RESPONSE

POLLED-REPORT-BY-EXCEPCION , UNSOLICITED-RESPONSED y PEER-TO-PEER

lo cual permite múltiples maestras.

En años recientes muchos vendedores han usado TCP/IP para transportar los mensajes

DNP 3 en lugar que los tradicionales medios seriales (RS 232 y RS 485) . La capa de

enlace de datos son inmersas en paquetes TCP/IP. Esta característica ha hecho que

DNP 3 tome ventaja de la tecnología Internet asi como de la tecnología Ethernet vía

redes LAN yWAN.

Este protocolo es utilizado en Norte América y Latinoamérica como protocolo de

comunicación entre el Centro de Control y las Subestaciones Eléctricas.

IEC J,0870-5-101

El IEC 60870-5-101 utiliza las capas 1, 2 y7 del Modelo OSI . Dicho protocolo puedes ser

implementado en dos modalidades:

A) Configuración tipo BUS, el cual utiliza una comunicación Maestra-Esclava con

interrogaciones cíclicas

B} Configuración dé _conexiones individuales,. el cual permite un balaceado acceso al

medio y envío de datos en ambas direcciones.

Las aplicaciones que efectúa dicho protocolo son las siguientes:

• Adquisición de datos por interrogación cíclica

• Adquisición de eventos

• Sincronización de tiempo

• Transmisión de ordenes

• Interrogación general

• Transferencia de archivos

Este protocolo es utilizado con mucha regularidad en Europa como protocolo de

comunicación entre el Centro de Control y las Subestaciones Eléctricas.

7

IEC 60870-5-103

Es un protocolo de comunicación creado para el intercambio de datos entre relés de

protección dentro de una Subestación.

La capa física soporta 02 ·configuraciones : RS485 tanto para su interface eléctrica como

de fibra óptica. Las velocidades de transmisión son de 9.6 kbps o de 19.2 kbps.

El protocolo opera como un Sistema Maestro esclavo y usa una interrogación cíclica

como método de acceso al medio. Soporta las capas 1, 2 y 7 del modelo OSI.

UCA2.0

El Electric Power Research lnstitute (EPRI) desarrolló la suite de protocolos conocida

como "Utilities Communications Architecture versión 2" (UCA 2.0) . Este protocolo es

basado en la utilización de Ethernet e incorpora la utilización de TCP/IP y MMS para las

capas de aplicación.

El protocolo utiliza las 07 capas del modelo OSI . El principio CSMA/CD de ethernet es

utilizado para el acceso al medio y soporta comunicaciones punto a punto así como

Maestro - Esclavo.

El protocolo UCA 2.0 puede ser utilizado dentro de una Subestación y hacia el centro de

control.

UCA 2.0 ofrece interconectividad e interoperatividad entre equipos de diferentes

fabricantes para intercambiar datos entiempo real en alta velocidad.

IEC 61850

¡,,IEC 61850 es un nivel superior al UCA 2.0 . Contiene. muchas de las especificaciones del

UCA 2.0 mas características adicionales . IEC 61850 fue publicada como estándar

internacional el año 2003.

Este protocolo es aplicable para la automatización y protección sobre Ethernet dentro de

una Subestación Eléctrica. Para el envío de información fuera de los limites de la

Subestación un estándar complementario se encuentra en desarrollo.

Actualmente los principales fabricantes de IEDs (ABB, AREVA, GE, SEL, SIEMENS)

ofrecen productos que cumplen con este estándar. IEC 61850 es diseñado para utilizar

una comunicación punto a punto a alta velocidad usando mensajería GOOSE (Generic

Object Orientated System Wide Events).

8

1.2.3 IEEE 802.3: Ethernet

El termino Ethernet se refiere a la familia de productos de Red de Area Local (LAN)

cubiertos por el estándar IEEE 802.3 el cual define el comúnmente conocido protocolo

CSMA/CD. 04 velocidades son actualmente definidos para operación sobre red de fibra

óptica y par trensado:

1 O Mbps - 1 O Base T Ethernet

100 Mbps - Fast Ethernet

1000 Mbps - Gigabit Ethernet

1 O Gigabit Ethernet el cual es el más reciente desarrollo publicado bajo el nombre IEEE

802.3ae como un suplemento al IEEE 802.3 .

Ethernet actualmente es usado por aproximadamente el 85% de las redes LAN de

computadoras de todo el mundo por sus siguientes cara!,'.:terísticas:

• Es fácil de entender, implementar , administrar y efectuar mantenimiento.

• Permite bajos costos de implementación de la red

• Posee una flexibilidad topológica en las instalaciones

• Garantía en la exitosa interconexión debido a que los productos cumplen un estándar

Ethernet LANs consisten de Nodos y medios de interconexión. El medio de interconexión

incluye 02 tipos de éable de cobre: Par trensado no apantallado (UTP) y par trensado

apantallado (STP)., adicionalmente existen muchos tipos de cables de fibra óptica. En

años recientes Wirelesss LAN (WI-FI) , estandarizado por el IEEE 802.11 ha sido

adicionado en muchas instalaciones.

1.2.4 IPV4 e IPV6

IPV4 es descrito en el Internet Engineering Task Force (IETF) RFC 791 (Septiembre

1981) 1Pv4 es la versión 4 del Protocolo IP (Internet Protocol). Esta fue la primera versión

del protocolo que se implementó extensamente, y forma la base de Internet.

1Pv4 usa direcciones de 32 bits, limitándola a 2A32 = 4.294.967.296 direcciones únicas,

muchas de las cuales están dedicadas a redes locales (LANs) en aproximadamente 18

millones o direcciones multicast (1 millon de direcciones) . Esto reduce el numero de

direcciones que pueden ser usados como direcciones publicas de internet y como el

numero de direcciones disponibles esta consumida, una escasez de direcciones parece

ser inevitable a la larga.

Para conectar dos redes LAN utilizando la porción publica de internet, son utilizadas

Virtual Prívate Network (VPN). VPNs trabajan insertando un Packete IP ( Packete

encapsulado) directamente dentro del campo de datos de otro packete IP ( Packete

9

encapsulador) y usando una dirección IP publica enrutable en el packete encapsulador.

Una vez que el packete VPN es enrutado alrededor de la red pública y encuentra al punto

final, el packete encapsulador es extraído y entonces transmitido en la red privada tan

igual como si las 02 redes privadas estuvieran directamente conectadas. Opcionalmente,

el packete encapsulado puede ser encriptado para asegurar el dato mientras viaja por la

red pública.

IP tiene la capacidad de proveer un parámetro llamado calidad del servicio (QoS) . En

una cabecera IP , 8 bits son asignados para definir a Tipo de Servicio (TOS) en términos

de prioridad , retardo, rendimiento de procesamiento y confiabilidad. La idea original fue

para especificar una preferencia sobre como la información será manejada en la Internet

cuando esta se envíe a un destino especifico. Esos bits han sido redefinidos muy

recientemente atraves del DIFFSERV Working Group del IETF y por los explícitos

códigos de Notificación de congestión. Además nuevas tecnologías están emergiendo

que requieren transmisión continua en tiempo real y por lo tanto se hará uso del campo

TOS. Un ejemplo es Voz sobre IP (VolP) el cual es usado para intercambio interactivo de

voz , otra aplicación seria aplicaciones en tiempo real SCADA en el ambiente de una

empresa eléctrica.

1Pv6 es la versión 6 del Protocolo de Internet (Internet Protocol), un estándar en

desarrollo del nivel dé red encargado de dirigir y encaminar los paquetes a través de una

red. 1Pv6 está destinado a sustituir al estándar 1Pv4, cuyo límite en el número de

direcciones de red admisibles está empezando a restringir el crecimiento de Internet y su

uso, especialmente en China, India, y otros países asiáticos densamente poblados. Pero

el nuevo estándar mejorará el servicio globalmente; por ejemplo, proporcionando a

futuras celdas telefónicas y dispositivos móviles con sus direcciones propias y

permanentes. Al día de hoy se calcula que las dos terceras partes de las direcciones que

ofrece 1Pv4 ya están asignadas

10

IPv4 soporta 4.294.967.296 (232) direcciones de red diferentes, un número inadecuado

para dar una dirección a cada persona del planeta, y mucho menos para cada coche,

teléfono, PDA, etcétera; mientras que IPv6 soporta

340.282.366.920.938.463A63.374.607.431.768.211.456 (2128 6 340 sextillones)

direcciones -cerca de 4,3 x 1020 (430 trillones) direcciones por cada pulgada cuadrada

(6, 7 x 1017 6 670 mil billones direcciones/mm2) de la superficie de La Tierra.

Adoptado por el Internet Engineering Task Force en 1994 (cuando era llamado "IP Next

Generation" o IPng), 1Pv6 cuenta con un pequeño porcentaje de las direcciones públicas

de Internet, que todavía están dominadas por IPv4. La adopción de IPv6 ha sido frenada

por la traducción de direcciones de red (NA T), que alivia parcialmente el problema de la

falta de direcciones IP. Pero NAT hace difícil o imposible el uso de algunas aplicaciones

P2P, como son la voz sobre IP (VolP) y juegos multiusuario. Además, NAT rompe con la

idea originaria de Internet donde todos pueden conectarse con todos. Actualmente, el

gran catalizador de IPv6 es la capacidad de ofrecer nuevos servicios, como la movilidad,

Calidad de Servicio (QoS), privacidad, etc. El gobierno de los Estados Unidos ha

ordenado el despliegue de IPv6 por todas sus agencias federales para el año 2008.

Se espera que IPv4 se siga soportando hasta por lo menos el 2011, dado que hay

muchos dispositivos heredados que no se migrarán a IPv6 nunca y que seguirán siendo

utilizados por mucho tiempo.

1.2.5 ICCP

Las empresas de servicios públicos alrededor del mundo especifican el lnter Control

Center Communications Protocol (ICCP) para proveer intercambio de datos entre centros

de control. ICCP cumple con el IEC 60870-6/TASE.2 .

ICCP opera sobre redes LANs y WANs para habilitar el intercambio de datos en tiempo

real , monitoreo y control de la información incluyendo valores de medición, datos de

planificación, datos de conteo de energía y mensajes del operador. Intercambio de datos

puede ocurrir entre los siguiente: Múltiples centros de control EMS, EMS y plantas de

poder DCS , EMS y Sistemas Scada de distribución, EMS y otros sistemas y

EMS/SCADA y Subestaciones.

Aplicaciones ICCP consisten de software Cliente y Servidor. El Software Cliente se

conecta a otros miembros de la red para solicitar datos y/o control. El software servidor

responde a las solicitudes del cliente por retornar el dato solicitado y ejecutar (si esta

permitido) la solicitud de control. Códigos de calidad tales como Setting Manual y Falla en

la telemetría son transmitidos con la información. Debido a la definición de grupos de

puntos llamados Virtual RTUs

11

En el Perú el COES establece como requerimientos que las empresas de Generación,

Transmisión y distribución Eléctrica remitan ciertos tipos de señales en protocolo ICCP

con el fin de monitorear en tiempo real el comportamiento en estado estacionario del

Sistema Interconectado Nacional.

1.2.6 Synchrophasores: IEEE Standard C37.118-2005

La medición Sincronizada del Fasor o Syncrophasor provee un método para comparar

ángulos de las tensiones y corrientes en cualquier lugar del Sistema Eléctrico en donde

se encuentre un IED que tenga estas características.

El equipo de medición del Fasor también llamado PMU es un equipo que reporta por

medio de un puerto de comunicaciones los valores en tiempo real de los fasores de

tensión y corriente los cuales son sincronizados por medio de un GPS. Para empresas de

Trasmisión los PMUs dan una fotografía instantánea del estado del sistema eléctrico. Se

estima que en EEUU la utilización del Syncrophasor permitirá incrementar en un 20% la

eficiencia de la transmisión de la energía eléctrica.

Actualmente esta norma se encuentra en revisión del IEEE Power System Relaying

Commitee.

1.2. 7 Sincronización de tiempo para comunicaciones en Subestaciones

Para soportar precisiones mejores que 1 milisegundo la IEEE 1588 Standard for a

Precision C/ock Synchronization Protocol for Networked Measurement and Control

Systems define un protocolo de sincronización de tiempo en sistemas de medición y

control implementados con tecnología de red. El protocolo es aplicable a sistemas de

comunicación de redes LAN tales como ethemet.

Para implementar ello en cada Subestación debe tenerse un GPS . Dicho GPS sincroniza

vía Network Time Protocol (NTP) o Simple Network Time protocol (SNTP) . El GPS debe

tener uno o más IRIG-8 conexiones para sincronizar equipos que no son posible de

sincronizar por intermedio de la red LAN.

1.3 Tendencias Industriales Actuales

12

El avance de la tecnología digital y las comunicaciones también hizo posible que

aparezcan nuevas tendencias aplicables en la automatización de Subestaciones.

1.3.1 Uso de los equipos Electrónicos Inteligentes (IEDs)

Hoy en día con el avance de la electrónica y las comunicaciones los tradicionales

equipamientos como medidores, relés de protección y Unidades Terminales Remotas

(UTR) han adquirido nuevas características y funcionalidades, una de ellas es la

capacidad de "hablar un lenguaje " (protocolo de comunicación) a fin de entregar toda la

información valiosa que dispone.

El termino IED el cual se utilizara a lo largo del presente informe se refiere a " cualquier

dispositivo utilizado en Subestaciones Eléctricas que incorpora uno o mas procesadores

con la capacidad de intercambiar datos y efectuar secuencias de control desde o hacia

una fuente externa"

1.3.2 Utilización de la Fibra Óptica

La Fibra óptica provee aislamiento eléctrico entre los equipos de comunicación y aísla al

personal y equipami�ntos de Sobre Tensiones peligrosas. Es totalmente inmune al ruido

causado por campos electromagnéticos y puede ser tendida en áreas donde la

instalación de cables de cobre sería peligroso o exista peligro de corrupción de la data.

Los nuevos avances hacen que la fibra óptica sea una alternativa practica, económica y

segura a los cables de cobre.

Numerosas pruebas han demostrado que los cables de cobre no apantallados y

apantallados no son confiables para ser utilizados en redes de comunicación de datos en

Subestaciones Eléctricas. Dichas pruebas muestran que los transitorios eléctricos de

corta duración tienen severo impacto en la comunicación Ethernet si se usan los cables

de cobre. Dichos transitorios aparecen por ejemplo en el momento que un relé de

protección efectúa un disparo del interruptor. Por lo tanto es recomendable que cables de

fibra óptica sean utilizados para conectar todos los IEDs hacia la red LAN de la

Subestación.

1.3.3 Migración de Comunicación Serial a Ethernet

13

Las comunicaciones seriales son tradicionales en las instalaciones de las empresas

eléctricas. Dichos equipos requieren una conexión física directa para enviar su

información hacia una RTU . Una desventaja de las comunicaciones seriales es que

usualmente se encuentra asociada a protocolos propietarios y cuentan con limitada

velocidad. Ethernet en cambio ha ganado popularidad pues ofrece interoperabilidad y

performance. Hoy en día existen equipos llamados terminal servers que convierten la

comunicación serial en Ethernet llamados Terminal Servers .

1.3.4 División de la Data en Operacional y No Operacional

Actualmente en los procesos de automatización es necesaria la división de la data en

Operacional y No Operacional para efectos de dar priorización de una información con

respecto a la otra y de esta forma optimizar la performance de los equipos de

comunicaciones.

La Data Operacional es la data en tiempo real que requiere un mínimo retraso entre el

momento en que esta se genera hasta su visualización por los operadores del Sistema de

Automatización. Ejemplos de ello son los estados de los equipos de protección y

seccionamiento (abierto/cerrado),

La Data No Operacional también llamada data de soporte, es la información sobre un

evento o situación que es almacenada en archivos por los IEDs. Esta data no esta sujeta

a la necesidad de una inmediata visualización y por lo tanto es considerara como de baja

prioridad en su entrega.

1.3.5 Ciber Seguridad

Hoy en día los terroristas alrededor del mundo pueden hacer mas daño atraves de un

teclado que con una bomba.

El primer ataque extendido atraves de la red fue en 1988 cuando un hacker ataco a 6200

computadoras y causo 98 millones de dólares en daños en solo 2 días.

Estadísticas de diferentes fuentes demuestran que los ataques del Ciber espacio están

creciendo en magnitud y consecuencia.

Un análisis de los daños del Blackout que afecto a los Estados Unidos revela que se

ocasionaron entre 6 y 1 O Billones de dólares en pérdidas. Imaginemos el impacto que

pudiese darse si un hacker hubiese efectuado un ataque al Sistema de potencia.

Debido a ello la North American Electric Reliability Corporation (NERC) estableció unos

estándares de Ciber Seguridad a fin de establecer la seguridad en la información de los

14

Sistema Eléctricos de Norte América. A continuación se presentan los siguientes

estándares de Ciber Seguridad los cuales deben ser tomadas en cuenta en todo proceso

de automatización de Subestaciones:

CIP-002-01- Critical Cyber Assets

Este estándar requiere la necesidad de la identificación y enumeración de los elementos

críticos del Sistema Eléctrico. Una vez que estos son determinados se aplican los

equipos de seguridad necesarios.

CIP-003-1 - Security Management Controls

Este estándar requiere la identificación de las entidades responsables que tendrán una

administración de la seguridad para proteger los componentes críticos del Sistema

Eléctrico. Se debe incluir específicamente políticas de seguridad , programas de

protección y clasificación de la información, programas de control de accesos.

CIP-004- Personnel and Training:

Este estándar requiere que el personal al cual se le da acceso a los elementos críticos de

la Subestación tenga conocimiento del riesgo que implica prestar la clave a otro personal.

Para ello se hace necesario programas de entrenamiento en temas de seguridad de la

información al personal involucrado.

CIP-005-Electronic Security

Este estándar requiere la identificación y protección del perímetro electrónico de

seguridad donde residen los elementos críticos del Sistema Eléctrico.

CIP-006- Physical Security of Critica! Cyber Assets

Este estándar requiere la implementación de un programa físico para la protección de los

elementos identificados en CIP-002-01 . Tales protecciones serian por ejemplo personal

de seguridad , mecanismos como necesidad de llaves de acceso y autorización para

acceder a los elementos críticos.

IEC 61850

La automatización de Subestaciones es un nuevo cambio para las empresas eléctricas

particularmente cuando las nuevas funcionalidades indicadas en la IEC 61850 son

utilizadas al máximo.

La automatización de Subestaciones es desde la aparición del IEC 61850 más que solo

la automatización de equipos. Es uno de los primeros pasos para la creación de un

altamente confiable sistema de potencia que responda rápidamente a los eventos en


necesaria para un costo efectivo en las operaciones. La automatización no es

simplemente el reemplazo de procedimientos manuales más bien debe permitir al

Sistema de potencia operar de una forma basada en la precisión de la información en el

momento oportuno.

En el pasado la atención de las empresas eléctricas estuvo enfocada solo en la

administración de la infraestructura del sistema de potencia. Sin embargo el mundo ha

cambiado, ahora hay 02 infraestructuras que deben ser administradas: La infraestructura

del Sistema de Potencia y la Infraestructura del Sistema de Comunicaciones.

La automatización de Subestaciones tal como la presenta la IEC 61850 no estuvo

disponible hasta hace algunos años atrás debido a que las comunicaciones no estuvieron

disponibles para soportar las aplicaciones que en ese entonces se requerían. Por lo tanto

uno de los principales habilitadores para que se logre la automatización de subestaciones

fue reconocer que el cableado extenso entre los equipos en patio de llaves y la sala de

control se podría eliminar con la aplicación de la tecnología Ethernet. Hoy en día el

desarrollo de las comunicaciones hace posible que las aplicaciones hasta ese entonces

soñadas se efectúen ahora.

17

La arquitectura por años utilizada en la automatización de Subestaciones estuvo

enmarcada por la utilización de redes seriales RS232 y RS485 así como por una gran

cantidad de cableado del patio de llaves hacia los relés de protección, medidores, RTUs ,

registradores de falla , etc. La Figura 2.1 indica la arquitectura entonces utilizada.

Luego con el avance de la tecnología digital los relés, medidores y RTUs se

transformaron en IEDs y la red Ethernet se convirtió en la red escogida por muchos a fin

de lograr la Automatización de la Subestaciones. La Figura 2.2 indica la arquitectura

actualmente utilizada. Como principal característica se nota los esfuerzos necesarios

para reducir el cableado.

Otro de los esfuerzos de los ingenieros de automatización fue buscar un protocolo de

comunicación único debido a los diferentes que existían en el mundo. En la Figura 2.3 se

presenta los principales protocolos de comunicación existentes en el mundo

Figura 2.3 : Protocolos de Comunicación alrededor del mundo

El objetivo buscado por años ha sido definir una infraestructura de comunicaciones que

permita una peñecta integración de los IEDs con independencia del fabricante. La

definición de un Bus de estación ha sido por años el centro de estandarización mundial.

También la búsqueda,continua en la reducción del cableado tanto del tipo eléctrico como

de comunicación así como el sacar las mayores funcionalidades a los IEDs son parte de

los innumerables desvelos de los ingenieros de Automatización. La respuesta a todos

esos requerimientos fue plasmada en la norma IEC 61850 tal como lo indica la Figura

2.2. Descripción

En los años 90 tanto la EPRI como la IEEE hicieron los primeros esfuerzos en lograr una

Utility Communications Arquitecture (UCA) . Se centraron primero en los protocolos de

comunicación entre Centros de Control el concluyo con las especificaciones ICCP mas

tarde adaptadas por el IEC como la 61850 TASE.2.

La siguiente fase del UCA llamada UCA 2.0 comenzó en el año 1994 y se enfoco en el

"Bus de datos de la Subestación". En el año 1996 el Comité Técnico 57 del IEC comenzó

a trabajar en la Norma IEC 61850 también enfocado al "Bus de datos de la Subestación".

En el año 1997 los 02 grupos de trabajo EPRI/IEEE e IEC unieron esfuerzos en la

definición de un estándar internacional que combine el trabajo de ambos grupos. El

resultado fue la norma IEC 61850 actual. En la Figura 2.5 se presenta el proceso de

desarrollo de la Norma IEC 61850

Figura 2.6 : Estructura del Estándar IEC 61850

El IEC 61850 provee interoperabilidad entre dispositivos electrónicos inteligentes (IED's)

para las aplicaciones de protecciones, monitoreo, medición, control y automatización en

las subestaciones. La funcionalidad de la automatización está dada por las tareas (de los

IED's) y no por el IEC 61850. De esta forma, el sistema de comunicaciones interno de la

subestación (Red LAN) es la red troncal de la automatización y el IEC 61850 es una

herramienta para el de diseño de la automatización. Este protocolo utiliza modelos

orientados a objetos para la descripción de los dispositivos y su funcionalidad y la

selección de la tecnología de comunicaciones está basada en las especificaciones de

23

usuario, lo cual constituye una las características más robustas del IEC 61850. La

funcionalidad de las interconexiones debe describirse también y se hace mediante la

ayuda del software "SCL" ("Substation Configuration description Language" herramienta

basada en lenguaje de marcaciones extensibles XML).

2.3. Características

lnteroperabilidad

El IEC 61850 requiere que cualquier IED que cumpla su norma provea un SCL

(generalmente un archivo) con la descripción de sus capacidades. El Nombre de tal

archivo es con extensión ICD (IED configuration description). Éste puede suministrarse

en CD o dentro de su misma unidad. Es importante que este archivo pueda ser leído por

otros dispositivos que cumplan la norma y tengan la herramienta. Además debe poseer

una base de datos para el integrador.

El resultado del proceso de diseño para IEC 61850 puede almacenarse en un archivo

seo que contiene las comunicaciones lógicas entre IED's dentro de las subredes y los

switches dentro de las subredes. Las figuras 2. 7 especifican todo el proceso de

interoperabilidad.

Tradicionalmente para lecturar desde un HMI la información que posee un IED esta es

reconocida por una serie de "Números Mágicos" los cuales representan tipos de datos. El

problema es que el "Contexto de los datos" se pierde y se requiere denodados esfuerzos

de ingeniería para lograr tener la configuración del Mapping de direcciones del HMI hacia

los IEDs.

Ahora con el IEC 61850 la información de un IED es dividida en "Grupos Lógicos" los

cuales a su vez se dividen en Nodos Lógicos . Adicionalmente se tienen Clases de Datos

correspondientes a cada Nodo Lógico. La Figura 2.1 O presenta un diagrama esquemático

del Mapping en IEC 61850

En el Anexo B se presenta la forma de efectuar los procesos de integración de IEDs bajo

la Norma IEC 61850.

26

Comunicación Punto a Punto (GOOSE)

GOOSE es un acrónimo de Generic Object Orintated System Wide Events . Esta

reemplaza el convencional Cableado para que los IEDs intercambien información entre

ellos. En el momento que se detecta un evento (cambio de estado de un Interruptor en un

IED por ejemplo) , el IED usa una comunicación del tipo Multicast para notificar a los

otros IEDs que se encuentran en el mismo BUS que ha ocurrido un evento. La

peñormance del tiempo de envío es exigente, no mas de 4ms es permitido como tiempo

transcurrido entre que el evento ocurra y hasta que este es transmitido a los otros IEDs.

La Figura 2.11 presenta el diagrama esquemático de los mensajes GOOSE entre IEDs

CB Object

CB1 CB2 CB3 CB4

Figura 2.11 : diagrama esquemático de los mensajes GOOSE entre IEDs

El Numero de IEDs, la topología de la red y el tipo de evento generado contribuyen a la

cantidad de datos que será generada después de un evento. Dado que las colisiones son

posibles en una red Ethernet , los mensajes son GOOSE son retransmitidos múltiples

veces por cada IED. Los Switches de 10MB y 100Mb pueden entregar 100 mensajes

GOOSE dentro de 4 milisegundos.

27

Bus de Proceso

Los términos Bus de Proceso y Bus de Estación inicialmente usados por las tempranas

publicaciones del IEC 61850 ahora son historia. Hoy en dfa IEC 61850 no efectúa

precisiones con respecto a· la arquitectura de la Subestación.

Cuando el IEC 61850 inicio planteo una arquitectura de 03 niveles : Bus de estación, Bis

de Bahía y Bus de proceso. El Bus de Estación (IEC 61850 , Parte 8) fue planeado para

la comunicación entre la Estación (PC) y el Nivel de Bahía (IEDs) , El bus de proceso

(IEC 61850, Parte 9) para la comunicación entre el nivel de bahía y el nivel de proceso.

La Figura 2.12 presenta el planteo inicial de la arquitectura por Niveles del IEC 61850.

statlon Level

Bay Level

Procesa Level

Figura 2.12 : Niveles lníciales del IEC 61850

Conforme el proceso de estandarización del IEC 61850 progreso y la armonización con el

UCA era necesario, se decidió que el IEC 61850 no restrinja los limites de las interfaces

de comunicación en los 03 niveles. Por lo tanto se decido que la comunicación Ethernet

(1S0/IEC 8802-3) sea la base de las comunicaciones.

IEC 61850-9-1 e IEC 61850-9-2 son dedicados para especificar los modelos para la

transmisión de las muestras de las formas de onda de los parámetros eléctricos a

monitorear.

IEC 61850-9-1 es unidireccional y es dirigido a utilizarse para una comunicación punto a

punto de las muestras de las formas de onda hacia un IED. El IEC 61850-9-2 es mas

general y está dirigida hacia una comunicación con varios IEDs.

2.4. El Futuro de IEC 61850

28

La edición Nro 2 del Estándar se encuentra actualmente en preparación. Dicha edición

incorpora nuevos requerimientos y nuevas aplicaciones tales como medición de la calidad

de la energía. Tenemos actualmente los siguientes desarrollos futuros de la norma IEC

61850:

IEC 61850 Fuera de la Subestación

- Actualmente se encuentra en desarrollo el estándar que permitirá la comunicación

bajo la norma IEC 61850 de los IEDs de diferentes subestaciones eléctricas.

- Actualmente se encuentra en desarrollo el estándar que permitirá la comunicación

bajo la norma IEC 61850 entre un centro de control y las subestaciones.

IEC 61850 en Centrales de Generación:

Actualmente se encuentra en desarrollo la norma IEC 61850 para Centrales

hidroeléctricas y Centrales Eólicas.

2.5. IEC 61850 y la "Red Inteligente Empresarial"

Actualmente las empresas eléctricas alrededor del mundo se encuentran transformando

su "red electromecánica" de la centuria anterior por la "red Inteligente" constituida por

IEDs y Computadores. Las mismas tecnologías que revolucionaron las computadoras y

las comunicaciones y crearon Internet ahora se encuentran transformando la

infraestructura de las Subestaciones Eléctricas.

Un numero de entidades tales como la EPRI y el Departamento de Energía de los EEUU

(DOE) han planteado iniciativas direccionadas a modernizar la infraestructura de las

empresas eléctricas así tenemos la "EPRl's lntelliGrid" y "DOE's GridWise".

La Figura 2.13 presenta una vista conceptual de los componentes típicos de la

información empresarial de una compañía eléctrica. Dicha infraestructura utiliza una

misma infraestructura para el acceso a la información en todas las áreas de la empresa.

Esta visión requiere una estratégico conocimiento de las necesidades de cada área y las

capacidades de integración de las mismas así como la integración de diversas bases de

datos.

29

Figura 2.13 : Red Inteligente Empresarial

Los habilitadores para que se forme la Red inteligente empresarial son los IEDs y el

protocolo IEC 61850.

2.6. Beneficios Económicos por Implementación del IEC 61850

La implementación de la Automatización de Subestaciones bajo el esquema del IEC

61850 ofrece los siguientes beneficios económicos a la empresa

1.- Ahorro en Costos directos de capital como resultado del monitoreo continuo de los

interruptores y transformadores por el uso de los IEDs. Esto trae como consecuencia un

ahorro por reducir la probabilidad de una falla catastrófica y la vida útil de dichos equipos.

Los mantenimientos usuales y mensuales se ven optimizados pues continuamente las

condiciones de los equipos principales de la subestación se encuentran monitoreadas.

2.- Ahorro por reducción en el tiempo de Análisis de la Falla . Los tiempos de análisis

de la · falla e investigación de sucesos permitirán la restauración inmediata de los

elementos críticos de una Subestación. Ello es posible gracias a las herramientas de

análisis de los IEDs (análisis de eventos, oscilografías y alarmas).

30

3.- Ahorro por el conocimiento preciso de las caracteristicas de sobrecarga de

líneas de transmisión y transformadores . El continuo calculo y monitoreo de las

condiciones dinámicas de los equipos por parte de los IEDs habilita a las empresas

eléctricas a plantear restricciones referentes a la máxima capacidad a transmitir sin

sobrecargar excesivamente los equipos y así evitar deterioro de sus aislamientos.

4.- Ahorro por el conocimiento oportuno y preciso de las alarmas asociadas a los

IEDs. El procesamiento inteligente de las alarmas de los IEDs de una Subestación hace

que se tomen las decisiones mas acertadas referentes al envio del personal a la

Subestación con los consiguientes gastos que esto implica.

5.- Ahorro por el conocimiento oportuno y preciso de los valores del Factor de

potencia y Tensión . El conocimiento del factor de potencia durante las horas punta y

fuera punta habilita a la empresa eléctrica a reducir las pérdidas eléctricas y a tener un

mejor conocimiento a la hora de efectuar transferencias de carga.

Los anteriores puntos fueron cuantificados por KEMA CONSULTING tomando como

ejemplo una empresa eléctrica americana . Dichos resultados son mostrados en la Tabla

CAPÍTULO 111

APLICACIÓNES ALREDEDOR DEL MUNDO DEL IEC 61850

3.1 Introducción

Hasta diciembre del año 2005 aproximadamente se han efectuado aproximadamente 11 O

Sistemas de Automatización de Subestaciones basados en el IEC 61850 . 70 de ellos ya

se encuentran en operación.

3.2 Aplicaciones Internacionales

SUIZA

ABB Suiza realizo la primera implementación mundial del IEC 61850 en Noviembre del

año 2004 . Hay sin embargo otros importantes proyectos iniciados incluyendo la

modernización dºe la Subestación Laufenburg en 380kV . Esta Subestación es un

importante nodo del Sistema Interconectado Europeo. El proyecto Laufenburg comenzó

en Diciembre del año 2004 y el punto central es lograr la modernización de 17 bahías

para fines del año 2006 utilizando el IEC 61850.

ALEMANIA

Alemania posee el mas grande numero de implementaciones operativas y cuenta con

muchas otras en proceso de pruebas. El punto de vista de un Fabricante Alemán es que

el Estándar IEC 61850 comience a ser el estándar único para comunicación de

subestaciones en el mundo. Esta opinión refleja el esfuerzo gastado para mejorar

. equipos y para definir configuración estandarizada. . Conforme se incremente el uso del

IEC61850 , otros protocolos de comunicación gradualmente desaparecerán. Otro factor

importante es que en 2/3 partes de los caso en donde se usa el IEC 61850 el nivel de

tensión es superior a los 100 kV lo cual indica la importancia de su utilización.

33

ITALIA

Tema, EL Operador del Sistema Eléctrico Italiano, ha desarrollado una serie de

especificaciones para el uso del IEC61850 como estándar dentro de las Subestaciones.

El nombre del proyecto llamado SICAS es un esfuerzo por crear un estándar integrado de

· comunicaciones que sirva a las necesidades de TERNA mientras al mismo tiempo ,

atraves del uso del IEC 61850, mantiene la autonomía del vendedor. Dicho requerimiento

especifica que los diseños de cada vendedor sean intercambiables en el Nivel de Bahía.

Por lo tanto, mientras el diseño de cada bahía podría diferir en aspectos, la comunicación

externa seria la misma.

ESPAÑA

IBERDROLA , una empresa eléctrica Española, ha diseñado un SAS (Sistema de

Automatización de Subestaciones) basado en el IEC 61850. Este proyecto es llamado

"Ciudad Universitaria" . El proyecto es diseñado para comprobar la efectividad del IEC

61850 y también comprobar la interoperabilidad entre IEDs.

Para lberdrola , el IEC 61850 abre nuevas posibilidades para la integración y uso de

Sistemas de Protección y Control. Además lberdrola considera dos características

importantes del protocolo que deben ser probadas:

lnteroperatibilidad : Equipos de protección y Control de diferentes fabricantes deberían

trabajar consistentemente como indica la teoría.

Herramientas de Ingeniería: Los beneficios de trabajos de ingeniería deberían

corresponder a la teoría.

La "Ciudad Universitaria" comenzó en el año 2004 con la creación de grupos de trabajo y

la participación de lberinco quien al igual que lberdrola, se familiarizo con el IEC 61850 y

. tuvo extensiva experiencia en SAS. Después de algún retardo en el proceso de

construcción de la Subestación , otra Subestación en España escogió introducir el IEC

61850.

Uno de las conclusiones del proyecto fue efectuar muchas consultas técnicas al grupo de

desarrollo del IEC 61850.

CONCLUSIONES

Las nuevas tendencias en la automatización de subestaciones de potencia son las

siguientes:

1. La utilización de IEDs con tecnología digitales como medidores, relés de protección y

Unidades Terminales Remotas (UTR) que ahora tienen nuevas características y

funcionalidades, una de ellas es la capacidad de "hablar un lenguaje " (protocolo de

comunicación) a fin de entregar toda la información valiosa que disponen.

2. La Utilización de la tecnología Ethernet en Fibra Óptica en Subestaciones.

3. El establecimiento de criterios de seguridad en la información procesada en las

subestaciones ( tales como la norma NERC indicada en 1.3.5).

4. Utilización de la Norma IEC 61850 en el ambiente de la Subastación la cual a su vez

trae los siguientes beneficios:

o lnteroperabilidad, IEDs de diferentes fabricantes pueden intercambiar y usar

información sobre medios de comunicación comunes (la funcionalidad en los

diferentes disp�sitivos no es necesariamente la misma).

o La ingeniería y configuración de datos es transportable entre herramientas de

diferentes fabricantes.

o Reduce la ingeniería y la configuración

o Capacidades de comunicación, adquisición de datos, y control son incluidas

directamente en los equipos primarios.

o Libre asignación de funciones en sistemas de configuraciones centralizadas odescentralizadas.

o Reducción del cableado convencional.

o Redes LAN en lugar de múltiples cables de cobre seriales en las Subestaciones

Eléctricas.

o Los servicios y las inversiones serán duraderos a pesar de los rápidos cambios

tecnológicos.

o El estándar está diseñado para seguir tanto el progreso en las tecnologías decomunicación, como los requerimientos que envuelven a estos sistemas.

5. Posibilita la creación de la "red inteligent e empresarial" el cual traería muchosbeneficios a las diferentes áreas de la empresa eléctrica.

The object of IEC is to prometeinternational co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes lnternational Standards, Technical Specifications,Technical Reports, and Guides (hereafter referred to as 'IEC Publication(s)'). Their preparation is entrusted totechnical committees; any IEC National Committee interested in the subject dealt with may participate in thispreparatory work. lnternational, governmental and non-governmental organizations liaising with the IEC alsoparticipate in this preparation. IEC collaborates closely with the lnternational Organization fer Standardization(ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevan! subjects since each technical committee has representation from allinterested IEC National Committees.

3) IEC Publications have the form of recommendations fer international use and are accepted by IEC NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible fer the way in which they are used or fer anymisinterpretation by any end user.

4) In order to promete international uniformity, IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible fer anyequipment declared to be; in conformity with an IEC Publication.

6) AII users should ensure that they have the lates! edition of this publication.

The main task of IEC technical committees is to prepare lnternational Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when

the required support cannot be obtained for the publication of an lnternational Standard, despite repeated efforts, or

the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an lnternational Standard.

Technical specifications are subject to review within three years of publication to decide whether they can be transformed into lnternational Standards.

IEC 61850-2, which is a technical specification, has been prepared by IEC technical committee 57: Power system control and associated communications.

INTRODUCTION

The IEC 61850 series is intended to provide interoperability between all devices in substations. Communication between these devices has to fulfil a lot of requirements imposed by all the functions to be per,formed in substations. Depending on the philosophy both of the vendor and of the user and on the state-of-the-art in technology, the allocation of functions to devices and control levels is not commonly fixed. This results in different requirements for the different communication interfaces within the substation. The IEC 61850 series shall support any allocation of functions.

The IEC 61850 series should have a long lifetime but be able to follow the fast changes in communication technology by both its technical approach and its document structure. Figure 1 shows the relationship of this part of the IEC 61850 series to subsequent parts of the IEC 61850 series. The IEC 61850 series has been organized so that changes to one part do not require a significant rewriting of another part, i.e. the parts are based on the communication requirements in this part of the IEC 61850 series; the derived modelling requirements in subsequent parts will not change the requirements of this part of the IEC 61850 series. The general parts, the requirement specification and the modelling parts are independent from any implementation. The implementation needed for the use of the IEC 61850 series is defined in sorne dedicated parts.

This part of the IEC 61850 series defines the communication requirements for functions and device models for substations.

The modelling of communication requires the definition of objects (for example, data objects, data sets, report control, log control) and services provided by objects (for example, get, set, report, create, delete). This is defined in IEC 61850-7-x with a clear interface to implementation. To use the benefits of communication technology, in the IEC 61850 series, no new OSI stacks are defined but a standardized mapping on existing stacks is given in IEC 61850-8-x and IEC 61850-9-x. A substation configuration language (IEC 61850-6) and a standardized conforman.ce testing complement the IEC 61850 series. Figure 1 shows the general structure of the documents of the IEC 61850 series, as well as the relative position of IEC 61850-5 within this series.

NOTE To keep the layered approach of the IEC 61850 series which does not mix application and implementation requirements, terms such as client, server, data objects, etc. are normally not used in this part of the IEC 61850 series (requirements). In IEC 61850-7-x (modeling), IEC 61850-8-x and IEC 61850-9-x (specific communication service mapping) terms belonging to application requirements such as PICOMs are normally not used.

1 Scope

COMMUNICATION NETWORKS AND SYSTEMS IN SUBSTATIONS -


This part of IEC 61850 applies to Substation Automation Systems (SAS). lt standardizes the communication between intelligent electronic devices (IEOs) and the related system requirements.

The specifications of this part refer to the communication requirements of the functions being performed in the substation automation system and to device models. AII known functions and their communication requirements are identified.

The description of the functions is not used to standardize the functions, but to identify communication requirements between technical services and the substation, and communication requirements between lntelligent Electronic Oevices within the substation. The basic goal is interoperability for all interactions.

Standardizing functions and their implementation is completely outside the scope of this part of IEC 61850. Therefore, a single philosophy for allocating functions to devices cannot be assumed in the IEC 61850 series. To support the resulting request for free allocation of functions, a proper breakdown of functions into parts relevant for communication is defined. The exchanged data and their required performance are defined. These definitions are supplemented by informative data flow calculations for typical substation configurations.

lntelligent electronic devices from substations such as protective devices are also found in other installations such as power plants. Using this part of IEC 61850 for such devices in these plants also would facilitate the system integration but this is beyond the scope of this part of IEC 61850.

INTRODUCTION

This part of the IEC 61850 series provides an overview of the architecture for communication and interactions between substation devices such as protection devices, breakers, transformers, substation host� etc.

This document is part of a set of specifications which details a layered substation communication architecture. This architecture has been chosen to provide abstract definitions of classes (representing hierarchical information models) and services such that the specifications are independent of specific protocol stacks, implementations, and operating systems.

The goal of the IEC 61850 series is to provide interoperability between the IEDs from different suppliers or, more precisely, between functions to be performed in a substation but residing in equipment (physical devices) from different suppliers. lnteroperable functions may be those functions that represent interfaces to the process (for example, circuit breaker) or substation automation functions such as protection functions. This part of the IEC 61850 series uses simple examples of functions to describe the concepts and methods applied in the IEC 61850

series.

This part of the IEC 61850 series describes the relationships between other parts of the IEC 61850 series. Finally this part defines how inter-operability is reached.

NOTE lnterchangeability, i.e. the ability to replace a device from the same vendor, or from different vendors, utilising the same communication interface and as a mínimum, providing the same functionality, and with no impact on the rest of the system. lf differences in functionality are accepted, the exchange may require sorne changes somewhere in the system also. lnterchangeability implies a standardisation of functions and, in a strong sense, of devices which are both outside the scope of this standard. lnterchangeability is outside the scope, but it will be supported following this standard for interoperability.

1 Scope


This part of the IEC 61850 series introduces the modelling methods, communication principies, and information models that are u sed in the parts of I EC 61850-7-x. The purpose of this part of the IEC 61850 series is to provide - from a conceptual point of view -

assistance to understand the basic modelling concepts and description methods for:

- substation-specific information models for substation automation systems,

- device functions used for substation automation purposes, and

- communication systems to provide interoperability within substations.

Furthermore, this part of the IEC 61850 series provides explanations and provides detailed requirements relatin_g to the relation between IEC 61850-7-4, IEC 61850-7-3, IEC 61850-7-2 and IEC 61850-5. This part explains how the abstract services and models of IEC 61850-7-x are mapped to concrete communication protocols as defined in IEC 61850-8-1.

The concepts and models provided in this part of the IEC 61850 series may also be applied to describe information models and functions for:

- substation to substation information exchange,

- substation to control centre information exchange,

- information exchange for distributed automation,

- information exchange for metering,

- condition monitoring and diagnosis, and

- information exchange with engineering systems for device configuration.

NOTE 1 This part of IEC 61850 uses examples and excerpts from other parts of the IEC 61850 series. These excerpts are used to explain concepts and methods. These examples and excerpts are informative in this part of IEC 61850.

NOTE 2 Examples in this part use names of classes (e.g. XCBR for a class of a logical node) defined in IEC 61850-7-4, IEC 61850-7-3, and service names defined in IEC 61850-7-2. The normative names are defined in IEC 61850-7-4, IEC 61850-7-3, and IEC 61850-7-2 only.

NOTE 3 This part of IEC 61850 does not provide a comprehensive tutorial. lt is recommended that this part be read first - in conjunction with IEC 61850-7-4, IEC 61850-7-3, and IEC 61850-7-2. In addition, it is recommended that IEC 61850-1 and IEC 61850-5 also be read.

INTRODUCTION

This document is part of a set of specifications, which details layered substation communication architecture. This architecture has been chosen to provide abstract definitions of classes and services such that the specifications are independent of specific protocol stacks and objects. The mapping of these abstract classes and services to communication stacks is outside the scope of IEC 61850-7-x and may be found in IEC 61850-8-x (station bus) and IEC 61850-9-x (process bus).

IEC 61850-7-1 gives an overview of this communication architecture. This part of IEC 61850 defines common attribute types and common data classes related to substation applications. These common data classes are used in IEC 61850-7-4. To define compatible data classes, the attributes of the instances of data shall be accessed using services defined in IEC 61850-7-2.

This part is used to specify the abstract common data class definitions. These abstract definitions shall be mapped into concrete object definitions that are to be used for a particular protocol (for example MMS, ISO 9506).

INTRODUCTION

The present standard includes all additional logical nodes, not included in IEC 61850-7-4:2003, required to represent the complete control and monitoring system of a hydropower plant.

Most of the Logical Nodes in IEC 61850-7-410 that are of general use, Logical Nodes the names of which do not start with the letter "H", will be transferred to the future Edition 2 of IEC 61850-7-4. In the same manner, all Common Data Classes specified in IEC 61850-7-410 will be transferred to future Edition 2 of IEC 61850-7-3.

Once future Editions 2 of IEC 61850-7-3 and IEC 61850-7-4 are published, IEC 61850-7-410 will be revised to include only those Logical Nodes that are specific to hydropower use.

Before Edition 2 of IEC 61850-7-410 is published, there will be a period where the Common Data Class (CDC) and Logical Node (LN) specifications will overlap with IEC 61850-7-3 (future Edition 2) and IEC 61850-7-4 (future Edition 2). During this time, the specifications in IEC 61850-7-3 (future Edition 2) and IEC 61850-7-4 (future Edition 2) will apply.

Part 7-410: Hydroelectrlc power planta -Communication for monitoring and control

IEC 61850-7-410 is part of the IEC 61850 series. This part of IEC 61850 specifies the additional common data classes, logical nodes and data objects required for the use of IEC 61850 in a hydropower plant.

The Logical Nodes and Data Objects defined in this part of IEC 61850 belong to the following fields of use:

• Electrical functions. This group includes LN and DO used for various control functions,essentially related to the excitation of the generator. New LN and DO defined within thisgroup are not specific to hydropower plants; they are more or less general for all types oflarger power plants.

• Mechanical functions. This group includes functions related to the turbine andassociated equipment. The specifications of this document are intended for hydropowerplants, modifications might be required for application to other types of generating plants.Sorne more generic functions are though defined under Logical Node group K.

• Hydrological functions. This group of functions includes objects related to water flow,control and management of reservoirs and dams. Although specific for hydropower plants,the LN and DO d�fined here can also be used for other types of utility water managementsystems.

• Sensors. A power plant will need sensors providing measurements of other than electricaldata. With a few exceptions, such sensors are of general nature and not specific forhydropower plants.

NOTE AII Logical Nodes with names not starting with the letter 'H" will be included in a future edition 2 of IEC 61850-7-4. When that document is published, the Logical Nodes in IEC 61850-7-4 (Edition 2) will take precedence over Logical Nodes with the same name in this part IEC 61850-7-410.

INTRODUCTION

This document is part of a set of specifications which details layered substation communication architecture.

This part of IEC 61850 is intended to provide inter-device operation of a variety of substation and feeder devices to achieve interoperability providing detailed information on how to create and exchange concrete communication messages that implement abstract services and models specified in IEC 61850-7-4, IEC 61850-7-3, and IEC 61850-7-2.

The mapping allows for data exchange over ISO/IEC 8802-3 Local Area Networks between all kinds of substation devices. Sorne of the protocol stacks used within this document are routable. Therefore the actual communications path may not be restricted to the LAN. Data exchange consists of real-time monitoring and control data, including measured values, to name just a few.

NOTE This part of IEC 61850 does not provide tutorial material. lt is recommended that IEC 61850-5 and IEC 61850-7-1 be read in conjunction with IEC 61850-7-2.

Part 8-1: Specific Communication Service Mapping (SCSM) -Mappings to MMS (ISO 9506-1 and ISO 9506-2)

and to ISO/IEC 8802-3

1 Scope

This part of IEC 61850 specifies a method of exchanging time-critica! and non-time-critica! data through local-area networks by mapping ACSI to MMS and ISO/IEC 8802-3 trames.

MMS services and protocol are specified to operate over full OSI and TCP compliant communications profiles. The use of MMS allows provisions for supporting both centralized and distributed architectures. This standard includes the exchange of real-time data indications, control operations, report notification.

This part of IEC 61850 specifies the mapping of the objects and services of the ACSI (Abstract Communication Service Interface, IEC 61850-7-2) to MMS (Manufacturing Message Specification, ISO 9506) and ISO/IEC 8802-3 trames.

This standard also specifies the mapping of time-critica! information exchanges to non-MMS protocol. The protocol semantics are defined in IEC 61850-7-2. This standard contains the protocol syntax, definition, mapping to ISO/IEC 8802-3 trame formats, and any relevant procedures specific to the use of ISO/IEC 8802-3.

This mapping of ACSI to MMS defines how the concepts, objects, and services of the ACSI are to be implemented using MMS concepts, objects, and services. This mapping allows interoperability across functions implemented by different manufacturers.

This part of the standard defines a standardized method of using the ISO 9506 services to implement the exchange of data. For those ACSI services, defined in IEC 61850-7-2 that are not mapped to MMS, this part defines additional protocols. This standard describes real substation devices with respect to their externa! visible data and behaviour using an object oriented approach. The objects are abstract in nature and may be used to a wide variety of applications. The use of this mapping goes far beyond the application in the substation communications.

This part of IEC 61850 provides mappings for the services and objects specified within IEC 61850-7-2, IEC 61850-7-3, and IEC 61850-7-4.

INTRODUCTION

61850-9-1 © IEC:2003(E)

This part of IEC 61850 applies to electronic current and voltage transformers (ECT and EVT) with a digital output via a. merging unit, for use with electronic measuring instruments and electronic protective devices.

The transformer technology can be based on optical arrangements equipped with electronic components, on air core coils (with or without a built-in integrator) or, on iron core coils with integrated burden and used as a current to voltage converter, alone or equipped with electronic components.

For digital output, this standard takes into account a point to point connection from the merging unit to electronic measuring instruments and electronic devices.

This mapping allows interoperability between devices from different manufacturers.

This standard does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. This standard specifies the externally visible functionality of implementations.

Reading Guide

• The point to point transformer interface as defined here is based on the concepts describedin IEC 60044-8. This standard extends this concept and proposes an alternative link layerto provide a solution for transmitting sampled measured values via Ethernet basedinterfaces. For the definition and measurement of the accuracy, synchronisation methods,data rates etc. of the transformers, refer to IEC 60044-8.

• This document can best be understood if the reader is thoroughly familiar with Parts 7-1,7-2, 7-3 and 7-4 of this Standard.

• No explanations to the ACSI services are given in this part of the standard. For detailedinformation about the use of the ACSI services, refer to IEC 61850-7-2.

Part 9-1: Specific Communication Service Mapping (SCSM) -Sampled values over serial unidirectional multidrop

point to point link

1 Scope

This part of IEC 61850 specifies the specific communication service mappings for the communication between bay and process level and it specifies a mapping on a serial unidirectional multidrop point to point link in accordance with IEC 60044-8. This part of IEC 61850 specifies a mapping of the abstract service for the transmission of sampled values (as defined in IEC 61850-7-2) on a serial unidirectional multidrop point to point link in accordance with IEC 60044-8. lt applies to the communication between merging units of electronic current (ECT) or voltage-transformers (EVT) and bay devices such as protection relays. lf higher requir:ements on sampling rate, further sampled measured value data sets in addition to the universal data set, inter-bay communication and synchronisation apply, these will be covered by IEC 61850-9-23. Figure 1 shows the schematics of this interface.

INTRODUCTION

This part of IEC 61850 defines the SCSM for sampled values over ISO/IEC 8802-3. The intent of this SCSM definition is to supplement IEC 61850-9-1 to include the complete mapping of the sampled value model.

This part of IEC 61850 applies to electronic current and voltage transformers (ECT and EVT having a digital output), merging units, and intelligent electronic devices for example protection units, bay controllers and meters.

Process bus communication structures can be arranged in different ways as described in Annex B and IEC 61850-1. In addition to the transmission of sampled value data sets, which are directly connected to ISO/IEC 8802-3, a selection of IEC 61850-8-1 services are necessary to support the access to the SV control block. References to the relevant IEC 61850-8-1 services are provided in this SCSM. For less complex devices (for example merging units) the sampled value control block can be pre-configured, in which case there is no need to implement IEC 61850-8-1 services based on the MMS-Stack.

This document defines the mapping of sampled value class model (IEC 61850-7-2) to ISO/IEC 8802-3. This SCSM, in combination with IEC 61850-7 and IEC 61850-6, allows interoperability between devices from different manufacturers.

This standard does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. This standard specifies the externally visible functionality of implementations together with conformance requirements for such functionalities.

Reading Guide

• This document is an extended mapping specification of IEC 61850-9-1 and IEC 61850-8-1to cover sampled value transmission over ISO/IEC 8802-3.

• This document can best be understood if the reader is thoroughly familiar with IEC 61850-7-1, IEC 61850-7-2, IEC 61850-7-3 and IEC 61850-7-4.

• The ACSI services defined in IEC 61850-7-2 are not explained in this part of the standard.

Part 9-2: Specific Communication Service Mapping (SCSM) -Sampled values over 1S0/IEC 8802-3

1 Scope

This part of IEC 61850 defines the Specific Communication Service Mapping (SCSM) for the transmission of sampled values according to the abstract specification in IEC 61850-7-2. The mapping is that of the abstract model on a mixed stack using direct access to an ISO/IEC 8802-3 link for the transmission of the samples in combination with IEC 61850-8-1.

Each SCSM consists of three parts:

- a specification of the communication stack being used,

- the mapping of the abstract specifications of IEC 61850-7 on the real elements of the stackbeing used, and

- the implementation specification of functionality, that is not covered by the stack beingused.

1 Scope



This part of IEC 61850 specifies standard techniques for testing of conformance of implementations, as well as specific measurement techniques to be applied when declaring performance parameters. The use of these techniques will enhance the ability of the system integrator to integrate IEDs easily, operate IEDs correctly, and support the applications as intended.

NOTE 1 The role of the test facilities for conformance testing and certifying the results are beyond the scope of this part of IEC 61850.

NOTE 2 The test approach and test system design to test a client device is likely to be different across the broad range of clients. There are many possibilities to test clients. The client tests are beyond the scope of this part of IEC 61850. lt is intended to define client test requlrements durlng the malntenance of this part.

TÉRMINOS USUALES

Este anexo presenta la interpretación de los términos usuales relacionados al tema y que

son utilizados en el informe.

1. IEDs. cualquier dispositivo electrónico utilizado en Subestaciones Eléctricas que

incorpora uno o mas procesadores con la capacidad de intercambiar datos y

efectuar secuencias de control desde o hacia una fuente externa. Ejemplos :

Reles de Proteccion, medidores , Equipos de Monitoreo de transformadores e

interruptores.

2. LAN . es la interconexión de varios IEDs , ordenadores, Switches, Routers. (LAN

es la abreviatura inglesa de Local Area Network o 'red de área local'). Su

extensión esta limitada físicamente a una Subestación o a un entorno de pocos

kilómetros. Su aplicación más extendida es la interconexión de ordenadores

personales y estaciones de trabajo en oficinas, fábricas, etc., para compartir

recursos e i,ntercambiar datos y aplicaciones. En definitiva, permite que dos o más

equipos se comuniquen

3. VPN . La Red Privada Virtual (RPV), en inglés Virtual Private Network (VPN), es

una tecnología de red que permite una extensión de la red local sobre una red

pública o no controlada, como por ejemplo Internet. Ejemplos comunes son, la

posibilidad de conectar dos o más sucursáles de una empresa utilizando como

vínculo Internet, permitir a los miembros del equipo de soporte técnico la conexión

desde su casa al centro de cómp_µto, o que un usuario pueda acceder a su equipo

doméstico desde un sitio remoto, como por ejemplo un hotel. Todo ello utilizando

la infraestructura de Internet.

4. TCP/IP. Es la familia de protocolos de internet � Es un conjunto de protocolos de

red en la que se basa Internet y que permiten la transmisión de datos entre redes

de computadoras. En ocasiones se la denomina conjunto de protocolos TCP/IP,

en referencia a los dos protocolos más importantes que la componen: Protocolo

de Control de Transmisión (TCP) y Protocolo de Internet (IP), que fueron los dos

primeros en definirse, y que son los más utilizados de la familia. Existen tantos

protocolos en este conjunto que llegan a ser más de 100 diferentes, entre ellos se

encuentra el popular HTTP (HyperText Transfer Protocol), que es el que se utiliza

para acceder a las páginas web, además de otros como el ARP (Address

183

Resolution Protocol) para la resolución de direcciones, el FTP (File Transfer

Protocol) para transferencia de archivos, y el SMTP (Simple Mail Transfer

Protocol) y el POP (Post Office Protocol) para correo electrónico, TELNET para

acceder a equipos remotos, entre otros.

5. IPV4, IPV6. IPv4 es la versión 4 del Protocolo IP (Internet Protocol). Esta fue la

primera versión del protocolo que se implementó extensamente, y forma la base

de Internet. IPv4 usa direcciones de 32 bits, limitándola a 232 = 4.294.967.296

direcciones únicas, muchas de las cuales están dedicadas a redes locales (LANs).

Por el crecimiento enorme que ha tenido del Internet (mucho más de lo que

esperaba, cuando se diseñó IPv4), combinado con el hecho de que hay

desperdicio de direcciones en muchos casos (ver abajo), ya hace varios años se

vio que escaseaban las direcciones IPv4. Esta limitación ayudó a estimular el

impulso hacia IPv6, que esta actualmente en las primeras fases de

implementación, y se espera que termine reemplazando a IPv4

6. Ethernet. es el nombre de una tecnología de redes de computadoras de área

local (LANs) basada en tramas de datos. El nombre viene del concepto físico de

ether. Ethernet define las características de cableado y señalización de nivel físico

y los formatos de trama del nivel de enlace de datos del modelo OSI. Ethernet se

refiere a las redes de área local y dispositivos bajo el estándar IEEE 802.3 que

define el protocolo CSMA/CD

7. DNP3. es un protocolo de adquisición de datos utilizado por las compañías

eléctricas, gas y agua con el fin de leer información de sus IEDs. Es diseñado

como un abierto, interoperable y simple protocolos para Sistemas Scada . Usa la

interrogación Maestra/Esclava para enviar y recibir información de IEDs.

8. UCVA 2.0. El Electric Power Research lnstitute (EPRI) desarrolló la suite de

protocolos conocida como "Utilities Communications Architecture versión 2" (UCA

2.0) . Este protocolo de adquisición de datos de IEDs es basado en la utilización

de Ethernet e incorpora la utilización de TCP/IP y MMS para las capas de

aplicación.

9. ICCP. También conocido como IEC 60870-6/TASE.2 . Es un protocolo de

intercambio de datos entre Centros de Control.

10. RTU. También conocido como UTR - Unidad Terminal Remota es un acrónimo

que define a un dispositivo basados en microprocesadores, el cual permite

obtener señales independientes de los procesos y enviar la información a un sitio

remoto donde se procese. Generalmente este sitio remoto es una sala de control

donde se encuentra un sistema central SCADA el cual permite visualizar las

184

variables enviadas por la UTR

11. Switch . en castellano "conmutador'', es un dispositivo electrónico de

interconexión de redes de ordenadores que opera en la capa 2 (nivel de enlace de

datos) del modelo OSI (Open Systems lnterconnection). Un conmutador

interconecta dos o más segmentos de red, funcionando de manera similar a los

puentes (bridges), pasando datos de un segmento a otro, de acuerdo con la

dirección MAC de destino de los datagramas en la red.

12. Router . en español enrutador, ruteador o encaminador es un dispositivo de

hardware para interconexión de redes de ordenadores que opera en la capa tres

(nivel de red). Un router es un dispositivo que permite asegurar el enrutamiento de

paquetes entre redes o determinar la ruta que debe tomar el paquete de datos.

13. Fibra Óptica. es un conductor de ondas en forma de filamento, generalmente de

vidrio, aunque también puede ser de materiales plásticos. La fibra óptica es capaz

de dirigir la luz a lo largo de su longitud usando la reflexión total interna.

Normalmente la 1oz es emitida por un láser o un LEO. Las fibras son ampliamente

utilizadas en telecomunicaciones, ya que permiten enviar gran cantidad de datos a

gran velocidad, mayor que las comunicaciones de radio y cable. También se

utilizan para redes locales. Son el medio de transmisión inmune a las

interferencias por excelencia

14. ICD. También llamado IED Configuration Description , Es el archivo que contiene'

las características de implementación del protocolo IEC 61850 en un IED.

15. SCD. Es el archivo que contiene la descripción de las comunicaciones lógicas

entre IEDs bajo el estándar IEC 61850.

16. GOOSE. es un acrónimo de Generic Object Orintated System Wide Events . Esta

reemplaza el convencional Cableado para que los IEDs intercambien información

entre ellos. En el momento que se detecta un evento (cambio de estado de un

Interruptor en un IED por ejemplo) , el IED usa una comunicación del tipo

Multicast (envío de información a múltiples destinos) para notificar a los otros IEDs

que se encuentran en el mismo BUS que ha ocurrido un evento
