Wide area measurements are becoming the basis of power system monitoring, protection and control. The frequency disturbance recorder (FDR) is actually a single-phase phasor measurement unit (PMU). It measures the voltage amplitude, angle and frequency from a single-phase 120-V wall outlet. Currently, the accuracy of synchrophasor measurements depends heavily on the precise time signal provided by...
