Interference Suppressing in Partial Discharge Measurements Based on LS-SVM Regression
In partial discharge (PD) measurements of electric power equipment there is always a lot of interference, of which the periodicity narrow-band interference demonstrates strongly in both time domain and frequency domain, so it must be filtered in advance. Based on the research of the threshold value of frequency domain and Wavelet filtering method, the least square support vector machine (LSSVM) regression algorithm is proposed in this paper to improve traditional method of frequency domain analysis, and which can adapt the narrow-band interference in a wider frequency band. Finally this method is used in interference suppressing of factual PD signals, the result shows that the method is effective.
