Investigating Synchrophasor Data Quality Issues
paper ID: 144
Abstract
Synchrophasor data is a real-time measurement of electrical quantities from across the power grid taken by Phasor Measurement Units (PMUs), which can substantially improve real-time situational awareness and control of the events happening on the power system. Currently, more than 1000 PMUs are installed across North America, computing and storing 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 and evolving efforts to characterize synchrophasor data quality.
