Wavelet transform (WT) is one of the most useful digital signal processing tools for time–frequency analysis of power quality disturbances in power systems. This paper presents an extensive bibliographic review of applications of WTs in the measurement and analysis of harmonic distortion in power systems, discussing the performance of the different methods proposed in the technical literature.
Wavelet transform is, at present, one of the most useful digital signal processing tools for time-frequency analysis of power quality disturbances in power systems. This paper presents a review of the applications of wavelet transforms in the measurement and analysis of harmonic distortion in power systems, discussing the performance, advantages and limitations of the different methods proposed in...
The proliferation of nonlinear load in the electric power system leads to steady-state waveform harmonic distortion. Since harmonic distortion has harmful effects on the electric power system, there is a need to analyze and hence accurately measure their values which is an issue of great concern especially in a deregulated environment. Conventional Fourier based analyzing tools have some limitations...
