Tony Faris JSIS Meeting October 2017 DFR/DDR Testing at BPA Tony Faris JSIS Meeting October 2017

Test Methodology Set trigger limits – frequency, voltage, etc. Create waveforms with test set State sim for step tests DFR records from field units for actual events COMTRADE playback Play waveforms into DFR/DDR Verify timestamp of event, accuracy of waveform, and any computed values Compare measurement with input signal Test back-to-back events

DFR Evaluation Criteria Length and reporting rate of event records Reporting rate of continuous recording Calculated/sampled values vs. point-on-wave Computed values – power, frequency, phasors Data formats – .csv, COMTRADE, etc. Expandable storage? Moving components? Time synchronization – GPS? IRIG-B? Architecture: external CTs/shunts, modules, etc. Portability and ease of installation Access to records
