摘要

笔者主要分析GIS典型绝缘缺陷引起的局部放电（PD）过程

并应用FDTD算法

分别以理想的高斯脉冲信号和真实PD电流信号为激励源

研究电磁波在GIS内部的传播特性

结果表明:PD实际电流信号与理想高斯脉冲激励下的电磁波相差较大

PD超高频电磁波传播特性仿真研究宜采用实测PD信号作为模拟激励源。

Abstract

The partial discharges（PD） caused by classic GIS insulation flaws are analyzed

and the propagation characteristic of electromagnetic wave excited by ideal Gauss pulse signal and actual PD current signal in GIS is investigated based on FDTD algorithm.The calculation results show that there is clear difference between the propagation characteristics of the two electromagnetic waves excited by ideal Gauss pulse signal and actual PD current signal.Actual PD signal should preferably be taken as exciting sources for simulation of propagation characteristic of PD-excited electromagnetic wave.
