摘要
局部放电与高压电气设备内部的绝缘有着紧密的联系,而局部放电检测技术已成为电气设备绝缘故障诊断的有效方法。近年来,利用小波变换分析局部放电信号技术越来越受到相关技术人员的重视,并且取得了飞快的发展。本文对小波分析阀值法做了相应改进,并用改进后的算法对信号滤波效果进行了仿真,取得了较好的效果。
There is close relation between partial discharge and the internal insulation of high voltage electrical equipment,while partial discharge detection technology has become an effective method for insulation fault diagnosis of electrical equipment.In recent years,partial discharge signal analysis technology with wavelet more and more relevant technical personnel's attention,and have a rapid development.This paper improves the wavelet threshold method,and make simulation for signal filtering effect with the improved algorithm,while that achieve good result.
