实测信号激励条件下GIS局部放电的电磁波传播特性研究
Electromagnetic Wave Propagation Characteristic of Partial Discharge in GIS Excited by Actual Signal
摘要
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.关键词
