Detection of Power Signal Singularity Based on Wavelet Transform

Zhang Shan-shan

Abstract

Singularity of power signal has great significance for the accidence.The wavelet transform has good localization property both in the time and frequency domains,can localize the singularity point precisely.The wavelet transform has used for detecting the signal singularity largely.In this paper,the application of wavelet transform in the detection of the singularity is briefly introduced,MATLAB simulation validates this method.
