Research on Influence Factors of Load Rejection Overvoltage in UHV AC Transmission Lines
摘要
Abstract
UHV AC transmission technology is an important strategy of energy development in China.Due to the large capacity and long distance of UHV AC transmission system,the system overvoltage and other phenomena have a greater impact on the system,so it is a urgent need to study the specific influencing factors of overvoltage and put forward suppression measures.This paper first makes analyses and studies on the influence factors of load shedding overvoltage in UHV AC transmission lines,and in a theoretical way,points out that the value of line overvoltage is directly related to the impedance,transmission current and power factor of the line,drawing out the influence factors to be studied.Secondly,the analysis model of load shedding overvoltage of UHV AC transmission line is established,laying the model foundation for the later simulation verification.Finally,the electromagnetic transient simulation software is used to carry out the simulation analysis of UHV AC line circuit breaker breaking resistance,transmission power of the transmission line,parameters of the reactor,deriving the UHV AC transmission line load shedding overvoltage suppression measures,which provides a reference for engineering applications,thus mitigating the impact of overvoltage on the system.关键词
