• Dispatchers and

engineers build their

own PI displays

Generator Database

Purpose

• Determine which PI tags are the correct PI tags for a piece of equipment

• Updated each night to ensure the most accurate information

Requirements

• Access to source system model (Oracle database)

• A strict PI tag naming convention

• Custom AF SDK coding

Top Level PECO Hierarchy Limerick Unit 01

PJM©201414

Source vs PI AF

• Each attribute of the

generator is automatically

assigned appropriate PI tag

• If there is no associated PI

tag a placeholder tag is

substituted which has a

snapshot value of “No

Result”

PJM©201415

Generator Database Automation

• Written by PJM PI administrator / developer Kireet Dholareeya

• .Net using AF SDK

• Loads source CIM model from Oracle database

• Builds hierarchy of pools, companies, stations and voltage levels using AF

templates

• Adds generators using templates based on their types

• AF templates use inheritance

– All generators must have specific attributes

– Wind units have additional attributes, etc

Generator Database Tools

• Process Book

• Coresight Displays

PJM©201417

Automatic Generation Control (AGC) Database

Purpose

• Detect data quality issues between PJM’s many redundant systems

• Replicates PJM’s tie line report

• Source to build reports and send notifications

Requirements

• Access to source system model

– Currently using manual XML exports

• A strict PI tag naming convention

• Custom AF SDK coding

PJM©201418

• PI Tag lookup done to translate

source system IDs into PI tag

names

• Calculation attributes created to

replicate existing EMS screens

• Additional alarm states

• Deviation calculations

AGC Database PI AF

PJM©201419

AGC Database Process Book ERD

Element Relative

• Shows

values from

5 different PI

Collectives

• Real-time

telemetered,

AGC, SE &

backup data

PJM©201420

AGC Database Notifications

• In testing phase: Might require AF 2014 to write AF formula

results to PI tags

• Using Notification Template

PJM©201421

AGC Database Notification Example

Subject: AGC Tie Deviation Violation on FALCONER-WARREN

Name: FAL-WAR / FALCONER-WARREN

Time:

AGC Value: 64.9941101074219 MW

SE Value: 71.0193710327148 MW

Deviation: 6.02526092529297 MW

Limit: 5.75 MW

PJM©201422

Synchrophasor Database

Purpose

• Initially developed for PI tag creation

• Recently added power calculations to investigate data quality issues

Requirements

• Source meta data

– Provided in excel sheets, manually entered into PI AF using PI system explorer

• Attention to detail

Synchrophasor Database Source Excel File

…

PJM©201424

Synchrophasor Database Model

• Meta data is manually

entered in PI AF

• Once it is verified PI AF is

used to create the PI tags

• Additional steps are

required to add PMUs to

output stream of PDC

(C37118) and RTDMS

(DNP3)

PJM©201425

Synchrophasor PMU Template (Partial)

• Example of substitution in STAT attribute allowing PI tag

creation using PI AF

• \\%@tag configuration|pi collective%\%@Zone%_%@Data

Synchrophasor Calculated Template

Calculates the complex, reactive and real power values from

current and voltage phasors

PJM©201428

Synchrophasor Power Calculation Coresight

When requesting long periods of time, high CPU usage on Coresight server.

Element Relative

PJM©201429

Synchrophasor Power Pivot Example

• Pick zone and/or

manufacturer to

display if any

PMUs are in error

• Also displays

latency and

frequency

PJM©201430

Thunder Storm Alert Database

Purpose

• Experimenting with AF 2014 and event frames

• Detect when thunder storm alert is active and capture an event frame

Requirements

• Data in PI and model manually created

PJM©201433

Thunder Storm Alert Coresight Display

• Easy way to

visualize event

frames

• Select event

frame and the

displays

updates with

the data from

the event

PJM©201434

Server Monitoring Database

Purpose

• PI Administrators to monitor the PI servers at PJM

• Notifications

• Visualization

Requirements

• Server performance monitor data

• Interface health points

PJM©201438

Conclusion

OSIsoft has greatly improved the

capabilities of PI AF over the last

few years

The PI client tools are now at a

point where they can take

advantage of PI AF

Event frames have great potential

now that they can be easily

generated

PI Coresight is a good tool but it

needs to be more customizable in

simple things like layout and

colors
