A Demodulation Technique For Power System Local Frequency And Voltage Measurements
Soliman, S.A.; Alammari, R. A.; Al-Kandari, M. A.; El-Hawary, M. E. ( Qatar University , 2003 , Article)The demodulation technique of two complex signals is used to estimate the power system local frequency and voltage phasor. The first complex signal is generated from the three-phase voltage waveform by using the ...
