1 2012 EMS User's Group MISO Synchrophasor Project

2 Dan s Background My primary focus has been centered around developing custom applications for energy companies. Illinois Power (10 years) Clinton Nuclear Power Station Operator apps IP Control Center worked on in-house developed EMS in Java with focus on substation protocols, RTU s and UI screens MISO (8 years) Developed many control room displays in C#.NET (RTD) Developed a few external web applications in Java Currently managing a team of developers 2

3 Presentation Objectives Real-Time Displays overview Phasor Project Requirements RTD application expansion Using Phasor Data in Real-Time Storing Phasor Data Playback Demo of the app 3

4 RTD History The app was built in to fill a niche of bringing data together from multiple systems while minimizing impact to those system through data caching. Real-Time Displays was developed to display Market, EMS, and Scheduling data side by side on one display either graphically or in a data grid. By 2009 the app had grown significantly and displays data from up to 8 data sources with 50+ displays. In 2010 the decision was made to build onto the RTD solution for sychrophasor data. 4

5 So what does the RTD app look like? Here are a few of the current screens: Dashboard Alarms Headroom Overviews Freq/BAAL Ramp Many others (Oh, this is me) 5

6 MISO Phasor Requirements Ability to graph data at 30 times per second. Ability to display data geographically Gradients and overlays Real-Time updating Playback ability Ad-hoc operator displays Calculated point definitions Data Quality monitoring and flagging Co-mingle data from multiple systems For example, EMS, PI, DART data alongside phasor data Store all the data. Users Control room, RT Engineers, ATF analysis, Members 6

7 Sounds easy but a few challenges. There sure is a LOT of data. 120 times as many readings for a data point compared to traditional 4 sec SCADA. Needed faster graphing solution than what was currently used in RTD. Needed framework for processing high speed data streams from What type of displays do the operators want? (they were skeptical of value in RT) Can that actually be streamed to a database? 7

8 OpenPDC Framework This open source software developed by TVA but now available from GPA. OpenPDC allows MISO to process data in real-time and also playback data within the same infrastructure. Works well for our custom build RTD application but can also be used for commercial products like (PhasorPoint, eterra Vision, SpaceTimeInsight, etc ) Extended the OpenPDC data model to manage MISO network model references (Company, Division, Station, Measurement) Also extended data model to keep configuration of UI elements and data quality adapters. 8

10 The best visualization appears obvious once complete. However, it is anything but straight forward to invent. - Scott Stapels 2011

23 Current Status MISO is preparing to enter parallel operations with our data management and visualization solution based on OpenPDC at the end of the year. Currently sourcing data from EMS, Oracle, PI, weather bug with plans to add TSAT, VSAT, National Weather service and web service interfaces. We like a lot of data currently over over 400,000 measurements on our way to 700,000 Storing data to Oracle via output adapter. Plan for 180k values with their associated quality codes a second 680M values an hour (close to 1.3B per hour if you count quality code separate from the data) 23
