2 Agenda About PJM PI AF Infrastructure AF Databases Generator AGC Synchrophasor Thunder Storm Alert Server Monitoring Conclusion 2

3 PJM Vision Statement To be the electric industry leader today and tomorrow in reliable operations, efficient wholesale markets, and infrastructure development. 3

4 Reliability Grid Operations Supply/Demand Balance Transmission monitoring 1 PJM Focus on Just 3 Things Regional Planning 15-Year Outlook 2 Market Operation Energy Capacity Ancillary Services 3 4

5 PJM as Part of the Eastern Interconnection 27% of generation in Eastern Interconnection 28% of load in Eastern Interconnection 20% of transmission assets in Eastern Interconnection KEY STATISTICS PJM member companies 900+ millions of people served 61 peak load in megawatts 165,492 MWs of generating capacity 183,604 miles of transmission lines 62, GWh of annual energy 791,089 generation sources 1,376 square miles of territory 243,417 area served 13 states + DC externally facing tie lines % of U.S. GDP produced in PJM As of 4/1/2014 5

6 PJM Control Room Many video walls and dispatcher workstations Majority of displays are PI Process Book Dispatchers and engineers build their own PI displays Reviewed by IT PI Support for performance reasons but not data 6

7 PI AF Infrastructure at PJM SQL Replication SQL Cluster AF Collective AF Server Primary AF Clients PI Process Book PI Data Link & Power Pivot PI Coresight SQL Cluster AF Server Secondary PI System Explorer Custom AF SDK Code 7

8 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 8

9 Generator Database Source 9

10 Generator Database Source 10

11 Generator Database Source (CIMSPY) 11

12 Generator Database Source (CIMSPY) 12

13 Generator Database PI AF Top Level PECO Hierarchy Limerick Unit 01 13

14 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 14

15 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 15

16 Generator Database Tools Element Relative Process Book Coresight Displays 16

17 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 17

18 AGC Database PI AF 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 18

19 AGC Database Process Book ERD Element Relative Shows values from 5 different PI Collectives Real-time telemetered, AGC, SE & backup data 19

20 AGC Database Notifications In testing phase: Might require AF 2014 to write AF formula results to PI tags Using Notification Template 20

21 AGC Database Notification Example Subject: AGC Tie Deviation Violation on FALCONER-WARREN Name: FAL-WAR / FALCONER-WARREN Time: AGC Value: MW SE Value: MW Deviation: MW Limit: 5.75 MW 21

22 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 22

23 Synchrophasor Database Source Excel File 23

24 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) 24

25 Synchrophasor PMU Template (Partial) Example of substitution in STAT attribute allowing PI tag creation using PI AF configuration pi configuration ;excdev=0;step=1;compmax=1;compdev=0;compdevpercent= configuration configuration configuration configuration enttag=pmu\stat 25

26 Synchrophasor Calculated Template Calculates the complex, reactive and real power values from current and voltage phasors 26

27 Synchrophasor Power Calculation Process Book Element Relative 27

28 Synchrophasor Power Calculation Coresight Element Relative When requesting long periods of time, high CPU usage on Coresight server. 28

29 Synchrophasor Power Pivot Example Pick zone and/or manufacturer to display if any PMUs are in error Also displays latency and frequency 29

30 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 30

31 Thunder Storm Alert Database Template Simple start and end triggers based off digital PI tag 31

32 Thunder Storm Alert Database Events Events that have been captured 32

33 Thunder Storm Alert Coresight Display Easy way to visualize event frames Select event frame and the displays updates with the data from the event 33

34 Server Monitoring Database Purpose PI Administrators to monitor the PI servers at PJM Notifications Visualization Requirements Server performance monitor data Interface health points 34

35 Server Monitoring Database Minimal data entry required Uses substitution to create PI tags 35

36 Server Monitoring Coresight Display PI Server Element Relative 36

37 Server Monitoring Coresight Display Windows Server Element Relative 37

38 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 38
