摘要：
In this paper, the principles of wavelet thresholding denoising methods were presented. In order to suppress Pesudo-Gibbs phenomenon caused by traditional denoising methods, translation invariant denoising method was then proposed. Finally, single frequency and multiple frequencies voltage flicker signals denoising were simulated with Matlab emulator. The perfect results of simulation show that translation invariant denoising method can denoise the signals effectively, which provides basis for voltage flicker signal analysis and detection.
