Abstract
In this paper, a new approach to estimate the power system frequency using wavelet transform is proposed. The wavelet function is expressed by the power series and is able to be performed by the z-transform, which can shorten the estimating time of the signal frequency compared with the Gabor function. Simulation results, in which the fundamental frequency (60Hz) or the harmonics frequency (300Hz) of the signals are quickly estimated by the proposed method, are presented and the online estimation of the frequencies is successfully achieved by the proposed method in the experimental system using DSP.
