ABSTRACT: This paper puts forward a new method based on Ensemble Empirical Mode Decomposition (EEMD) and Kernel Independent Component Analysis (KICA) for de-noising to extract the Partial Discharge (PD) signals against narrow-band noise. At first, this method used EEMD to decompose the detection signal to get Intrinsic Mode Function (IMF) components which would be the inputs of KICA algorithm, then KICA could extract PD from the detection signal. The method is introduced to separate the PD signals against the narrow-band interferences of multifrequency and multiamplitude. ...
