小波包在局放信号极性检测中的应用
APPLICATION OF WAVELET PACKETS
IN DETECTING POLARITY OF PARTIAL DISCHARGE SIGNAL
摘要
Abstract
The polarity of the partial discharge (PD) signal is very useful for the judgment of the possible root cases of different partial discharge. However, it is difficult to get the polarity information of PD for on-line monitoring system due to noise. The relationship between the different class PD and polarity of PD signal is discussed in this paper, the algorithm using Wavelet Packets (WP) to distinguish the polarity of PD signal is given. Simulation results show that this method is feasible and can pick-up the polarity information of PD under strong interference.关键词
