Section 1 Introduction

About this chapterThis chapter explains concepts and conventions used in this manual and providesinformation necessary to understand the contents of the manual.

1.1 Introduction to the technical reference manual1.1.1 About the complete set of manuals for an IED

The users manual (UM) is a complete set of five different manuals:

en06000097.vsd

Applicationmanual

Technicalreference

manual

Installation andcommissioning

manual

Operatorsmanual

Engineeringguide

The Application Manual (AM) contains application descriptions, setting guidelinesand setting parameters sorted per function. The application manual should be used tofind out when and for what purpose a typical protection function could be used. Themanual should also be used when calculating settings.The Technical Reference Manual (TRM) contains application and functionalitydescriptions and it lists function blocks, logic diagrams, input and output signals,setting parameters and technical data sorted per function. The technical referencemanual should be used as a technical reference during the engineering phase,installation and commissioning phase, and during normal service.The Installation and Commissioning Manual (ICM) contains instructions on howto install and commission the protection IED. The manual can also be used as areference during periodic testing. The manual covers procedures for mechanical andelectrical installation, energizing and checking of external circuitry, setting andconfiguration as well as verifying settings and performing directional tests. Thechapters are organized in the chronological order (indicated by chapter/sectionnumbers) in which the protection IED should be installed and commissioned.The Operators Manual (OM) contains instructions on how to operate the protectionIED during normal service once it has been commissioned. The operators manual

Section 1Introduction


can be used to find out how to handle disturbances or how to view calculated andmeasured network data in order to determine the cause of a fault.The IED 670 Engineering guide (EG) contains instructions on how to engineer theIED 670 products. The manual guides to use the different tool components for IED670 engineering. It also guides how to handle the tool component available to readdisturbance files from the IEDs on the basis of the IEC 61850 definitions. The thirdpart is an introduction about the diagnostic tool components available for IED 670products and the PCM 600 tool.The IEC 61850 Station Engineering guide contains descriptions of IEC 61850station engineering and process signal routing. The manual presents the PCM 600and CCT tool used for station engineering. It describes the IEC 61850 attribute editorand how to set up projects and communication.

1.1.2 About the technical reference manualThe technical reference manual contains the following chapters: The chapter Local human-machine interface describes the control panel on

the IED. Display characteristics, control keys and various local human-machineinterface features are explained.

The chapter Basic IED functions presents functions that are included in allIEDs regardless of the type of protection they are designed for. These arefunctions like Time synchronization, Self supervision with event list, Test modeand other functions of a general nature.

The chapter Current protection describes functions such as overcurrentprotection, breaker failure protection and pole discordance.

The chapter Voltage protection describes functions like undervoltage andovervoltage protection as well as residual overvoltage protection.

The chapter Frequency protection describes functions for overfrequency,underfrequency and rate of change of frequency.

The chapter Multipurpose protection describes the general protection functionfor current and voltage.

The chapter Secondary system supervision includes descriptions of functionslike current based Current circuit supervision and Fuse failure supervision.

The chapter Control describes the control functions. These are functions likethe Synchronization and energizing check as well as several others which areproduct specific.

The chapter Logic describes trip logic and related functions. The chapter Monitoring describes measurement related functions used to

provide data regarding relevant quantities, events, faults and the like. The chapter Metering describes primarily Pulse counter logic. The chapter Station communication describes Ethernet based communication

in general including the use of IEC61850, and horizontal communication viaGOOSE.

The chapter Remote communication describes binary and analog signaltransfer, and the associated hardware.

The chapter Hardware provides descriptions of the IED and its components.

Section 1Introduction


The chapter Connection diagrams provides terminal wiring diagrams andinformation regarding connections to and from the IED.

The chapter Time inverse characteristics describes and explains inverse timedelay, inverse time curves and their effects.

The chapter Glossary is a list of terms, acronyms and abbreviations used inABB technical documentation.

1.1.3 Design of the Technical reference manual (TRM)The description of each IED related function follows the same structure (whereapplicable). The different sections are outlined below.

1.1.3.1 IntroductionOutlines the implementation of a particular protection function.

1.1.3.2 Principle of operationDescribes how the function works, presents a general background to algorithms andmeasurement techniques. Logic diagrams are used to illustrate functionality.

Logic diagramsLogic diagrams describe the signal logic inside the function block and are borderedby dashed lines.

Signal namesInput and output logic signals consist of two groups of letters separated by two dashes.The first group consists of up to four letters and presents the abbreviated name forthe corresponding function. The second group presents the functionality of theparticular signal. According to this explanation, the meaning of the signal BLKTR infigure 4 is as follows: BLKTR informs the user that the signal wi
