Abstract
Aiming at the problem that more and more nonlinear loads of power system lead to the pollution of electrical network harmonic,the wavelet transform method was put forward based on Mallat arithmetic in order to improve accuracy of measuring.This method picked up every existent harmonic of the signal by using its multi-resolution analysis,realized the measurement of harmonic parameters within each band and tracked observation of harmonic change.The simulation results proved that the method was feasible and effective.关键词
