摘要
Abstract
The existing main wavelet denoising methods include threshold method, spatial correlation method, and modulus maximum method, however they all have some limitations. Combining the features and application ranges of the threshold method and modulus maximum methods, a new wavelet denoising algorithm was proposed and programmed in this paper. Moreover, the transformer's partial discharge signals were analyzed by the program. The experimental results demonstrate that the algorithm can eliminate white noise, and suppress strong electrical pulse interference to a certain extent, which suggests the algorithm can be applied in engineering to process transformer's partial discharge signals.关键词
