| Abstract: | This paper discussed the detecting methods and disturbances of partial discharge in aviationgenerator. The method of multiresolution analysis of Wavelet Transform is applied into detecting PD signal from signal with low SNR, and partial discharge signal with noises are simulated. The simulation results show that this method is available, and which provide the theoretical basis for detecting insulating state of aviationgenerator stator winding. |
