ESTIMATION OF REAL-TIME POWER SYSTEM QUANTITIES USING TIME-SYNCHRONIZED MEASUREMENTS

ESTIMATION OF REAL-TIME POWER SYSTEM QUANTITIES USING TIME-SYNCHRONIZED MEASUREMENTS

Phasor measurement units (108) provide phasor data from various locations (102) in an electrical power system. The phasor data is referenced to a common timing signal. Non-phasor measurement data is also obtained at various locations in the power system. A phasor assisted state estimator (120) uses...

Zusammenfassung:Phasor measurement units (108) provide phasor data from various locations (102) in an electrical power system. The phasor data is referenced to a common timing signal. Non-phasor measurement data is also obtained at various locations in the power system. A phasor assisted state estimator (120) uses the phasor data and the non-phasor data to determine the power system state.
