Abstract
Online monitoring of gas insulated substation(GIS) is increasingly applied in power system,and remarkable effect has been obtained.But there are still many problems in the field calibration and quantitative evaluation of online monitoring devices.The paper establishes a defect simulation platform for online monitoring 1 100 kV GIS,obtaining the detection UHF spectra and the apparent discharge quantities through experiment.The attenuation propagation characteristics of UHF signal in GIS are studied.By using the pulse injection method,obtaining the relationship between steep pulse injection and the apparent discharge capacity,and the characteristic value of the typical GIS attenuation is obtained,which provides a theoretical basis for field verification technology for a 1 100 kV GIS online monitoring system.关键词
