Investigating Synchrophasor Data Quality issues

Phasor Measurement Units (PMUs) installed across North America, compute and store synchrophasor data at select locations. However, the efforts to process the synchrophasor data to meet very high operator trust expectations has been challenging. This paper describes Synchrophasor Data Quality (SDQ) Activity, Trustworthy Cyber Infrastructure for the Power Grid (TCIPG) Project efforts to investigate synchrophasor data archived from American Transmission Company's system including both observations from the field to characterize synchrophasor data quality.
