Synchrophasor measuring device and inter-bus-line phase angle difference measurement unit using the same

Voltage instantaneous value time-series estimation data and a present-time voltage estimation value are calculated by using an actually-measured frequency and voltage instantaneous value time-series data according to a least square method. A present-time voltage effective value is determined by usin...
