摘要

介绍了基于脉冲电流波形用于GIS局部放电检测的新型抗干扰技术。该抗干扰技术由脉冲电流波形的特征提取以及基于波形特征的聚类分析实现。其中

脉冲电流波形的特征提取由基于时频波形和频域波形的等效时频法

而快速聚类分析则由模糊C均值聚类（FCM）实现。受干扰脉冲源影响的电晕放电仿真试验和基于宽带局部放电检测的GIS母线毛刺试验均验证了该新型抗干扰技术的可行性和实用性。

Abstract

A novel approach of anti-interference used in PD detection based on pulse current waveshape is introduced in this paper.This novel anti-interference technique is composed of the equivalent time-frequency parameters extraction for pulse current sequence and the Fuzzy C-means（FCM）unsurprised clustering analysis.Simulation test result and PD signals extraction of corona discharge from on-filed GIS test show that this anti-interference technique proposed is feasible and practical

which provides a good approach to extract PD signals form GIS.
