Frequency Tracking In Power Networks Of Harmonics
Additional Document Info
1992. IEEE. All rights reserved. Three new techniques for frequency measurement are pro-, posed in the piper. The first is a modified zero crossing method using curve fitting of voltage simples. The Becond method is based on polynomial fitting of the DFT quasistationary phasor data for calculation of the late of change of the positive sequence phase angle. The third method operates on a complex signal obtained by the standard technique of quadrature demodulation. All three methods are characterized by immunity to reasonable amounts of noise and harmonics in power systems. The performance of the proposed techniques is illustrated on several scenarios by computer simulation.
