基于sVD-小波熵融合的电机系统故障分离方法
Fault Isolation Method of Motor System Based on SVD & Wavelet Entropy
摘要
Abstract
To restrain the effect of power frequency interference on current signals, this paper studies the characteristics of singular value decomposition(SVD)and wavelet entropy and proposes a high-precision separation method of faults, in which the strong denoising capability of SVD is used to effectively eliminate the complex nose signal and the method of wavelet entropy is used to separate the fault current signals. The results show that the method can be used to effectively eliminate the power frequency interference and detect the weak signal.关键词
