July 9, 2012 2Committee Report:Joint Synchronized Information Sub-CommitteeOperating entities in the Western Interconnection and US Department of Energy are investing inexcess of $108 M in the synchro-phasor infrastructure. As the projects shift from equipmentinstallation to application deployment, the WECC Joint Synchronized Information Subcommittee(JSIS) is in unique position to support these efforts. WECC JSIS is taking steps to align its workplan with the needs of the SGIG projects to fully utilize the benefits of the investments.WECC JSIS activities:1. Analysis of power system dynamic performance (on-going activity by operating entities)a. Event analysis and system performance evaluationb. Power plant performance analysis and model validationc. Lesson’s learned papers2. Engineering applications of synchro-phasor dataa. Data mining and event detection toolsb. Synchro-phasor data conditioning and verification.c.

Event Analysis andSystem PerformanceEvaluation –Generation Loss1b. Power PlantPerformanceMonitoringPDCI probing tests are conductedby BPA every other Thursday fromlate March to mid-September.WECC JSIS is collecting PMUrecordings from the tests for theanalysis. The tests are needed forbaselining the oscillatoryperformance in the West, as well asfor tuning the Mode Meterapplication.WECC JSIS members (SCE, SRPand PG&E) send outannouncements of large generationoutages in the West, includingpreliminary performance analysisusing PMU data.WECC JSIS keeps the baseline ofthe frequency response metrics.BPA developed a PI-basedapplication for power plantfrequency response monitoringusing SCADA data. The data willhelp the WECC Modeling andValidation Work Group to updategovernor response modelinformation (baseload, under loadcontrol, responsive)Continue probing tests and datacollection. Complete analysis ofthe system oscillatoryperformance, advise Mode MetertuningContinue monitoring the events ofgeneration outages.Expand the frequency responsemetrics to monitoring the powerpick-up on major transmissionpaths.Share the power plant frequencyresponse application with otheroperating entities in the West.Expand the application to usingPMU dataW E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C O U N C I L • W W W .

Oscillation Montana Tech is developing an WECC RC and operating entitiesDetectionOscillation Detection application to start testing Oscillation3a. OscillationDetection Baselineunder WISP projectBPA asked PNNL to baselinespectrum of key path flows,voltages and frequencies.3b. Mode Meter Montana Tech is developing aMode Meter application underWISP project.BPA has been testing an earlierversion of Mode Meter in BPA lab.3c. Voltage Stability Many transmission paths in theWest are voltage-stability limited.JSIS believes that measurementbasedvoltage stability applicationshave high value in the West.US DOE issued an RFP ondeveloping algorithms for on-linevoltage stability assessment using3d. Operator TrainingMaterials3e. Studies todetermine oscillationmitigation procedures3f. Studies to determinephase angle alarmlimitsonly synchronized measurements.BPA conducted synchro-phasortraining during its 2011 Fall and2012 Spring dispatcher training.JSIS is in process of conductingstudies to determine operatoractions to mitigate the oscillationsand low damping conditions. Studyplan is developed. Seed base casesare prepared. Contingency files aredeveloped. Analysis tools aredeveloped. The studies are currentlyin progress.Detection applicationComplete the baseline spectrum ofkey path flows, voltages andfrequencies.Start baselining spectrum of largegenerating facilities.WECC RC and operating entitiescontinue testing Mode Meterapplication.WECC JSIS submitted a fundingrequest to deploy the voltagestability applications at theoperating entities. While WECCproject is expected to leverage themethods developed under DOEproject, the two projects arecompletely separate.Review operator trainingmaterials at the upcoming JSISmeeting.Complete the studies, issue studyreport and recommendations.Develop a study plan for settingphase angle alarm limits.W E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C O U N C I L • W W W .
