Application of Multiwavelet Multiresolution Analysis in Signal Processing of Power Systems

Multiresolution analysis method of multiwavelet was briefly introduced. Its application in fault monitoring, fault data compression and denoising was studied, and its performances in fault diagnosis and monitoring and fault data processing were compared with traditional wavelet. Simulation results show that the performances of multiwavelet is better in general than those of traditional wavelet if a proper preprocessing method is adopted in multiwavelet.
