 note = {A new approach to estimate the power system frequency and signal components using wavelet transform is proposed in this paper. The wavelet function is expressed by the power series terms and is able to be performed by the z-transform, which can shorten the estimating time of the signal frequency compared with the general convolution integral. The fundamental frequency (60Hz) or the harmonics frequency (300Hz) of the signal is quickly estimated. The on-line frequency estimation by the proposed method is successfully achieved in the experiment using the DSP system. The application using Induction motor system and the rectifier system., 2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM) : Ischia, Italy, 2008.06.11-2008.06.13, SPEEDAM 2008, pp.1242-1247; 2008},
