| 摘 要： | 为去除XLPE电缆局部放电现场检测中的随机脉冲干扰,采用等效时频法提取脉冲特征,对特征进行自适应模糊聚类,以相位集中度为指标区分局放与随机干扰.对现场数据分析处理的结果表明,该方法能够有效去除信号中的随机脉冲干扰,为评估XLPE电缆的绝缘状态提供了较好的理论和实践依据.

| Abstract: | To suppress the stochastic pulse interference in XLPE Cables,this paper uses equivalent time-frequency method to extract pulse feature values,adaptive fuzzy clustering to classify pulses,phase concentration as an index to distinguish PD(partial dischange)and stochastic pulses.Analysis results of on-site data show that this method can effectively suppress stochastic pulse interference in the PD signal,providing a useful theoretical and practical basis to assess the state of XLPE cable insulation. |

| Keywords: | adaptive fuzzy clustering partial discharge stochastic pulse interference |
