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 .
