| 摘 要： | 在电能质量检测领域,测量信号通常叠加着随机噪声,因此在噪声污染比较严重的场合,对检测到的信号一般要进行去噪处理.针对此类噪声问题,利用信号与噪声进行小波变换后在各尺度空间呈现的不同特性,提出了基于小波变换的阈值去噪法.

| Abstract: | In the field of power quality detection, along with the signals sampled there are always noises, so the signals sampled need denoising at some occasions with serious noise pollution. In accordance with this kind of noise pollution problem, the threshold measurement for denoising based on wavelet transform is brought forward in the paper. According to the fact that the maximum wavelet transform modulus of noise and that of the signals have different characters in wavelet space. |

| Keywords: | power quality wavelet transform denoise threshold |
