摘要	Aiming at the existing statistical bias phenomenon of traditional mathematical morphological filter, based on the least mean square (LMS) adaptive algorithm adjusting the structure elements of different length, an adaptive generalized mathematical morphology filter is proposed. In the strong noise environment, by comparative analysis of simulation using mathematical morphology, generalized mathematical morphology and adaptive generalized mathematical morphology methods to eliminate the continuous periodic narrowband interference. And introducing to signal noise ratio and partial discharge pulse waveform distortion of the mean square error evaluation index, the results of simulation analysis and field data processing show that adaptive generalized mathematical morphology filter effect is better than signal morphology filter effect, which completely keep the geometric structure characteristics of partial discharge signals, and the distortion of signals is small. Analysis results show that the adaptive generalized mathematical morphology effectively inhibits the continuous periodic narrowband interference.
