小波变换区域相关去噪在电能质量监测的应用

In this paper, the region correlation denoising algorithm is applied to power quality denoising according to the poor correlation between the white noise in the wavelet transform scales. Through Matlab simulation, the method proposed in this paper can effectively preserve the transient abrupt signals in power system denoising, and can obtain higher signal-to-noise ratio and lower reconstruction mean square error. This method can well retain the local characteristic signal of power quality, and can effectively remove white noise.
