Inner Overvoltage of Zhefu UHV AC Power Transmission Project
In view of the problem of inner overvoltage of Zhefu UHV AC Power Transmission Project,this paper adopts EMTP simulation to research switching overvoltage,power frequency overvoltage and resonance overvoltage.This research can provide propor reference to restricting the overvoltage level of UHV system and choosing appropriate insulating level,and ensure the safe and stable operation of UHV power transmission project.
