Research Progress of Wavelet Denoising Method of Transformer Partial Discharge Signal

摘要：

　　Wavelet analysis has been widely used in the denoising of partial discharge signal of transformer.This paper introduces the main method of partial discharge signal denoising,which focuses on the studying of wavelet denoising methods.The main wavelet denoising methods are introduced herein including wavelet decomposition and reconstruction method,wavelet thresholding method,the translation invariant wavelet thresholding method,the wavelet denoising based on modulus maxima method,and the most widely used wavelet thresholding is introduced primarily.The analysis of their advantages and disadvantages is helpful to choose a proper wavelet denoising method.
