摘要
柔性直流输电线路较长,易发生故障,为了提高线路可靠性,需要准确可靠地故障定位技术进行保护。本文总结了国内外柔性直流输电网故障定位的研究现状,对故障定位原理进行了归类研究,将直流输电线路故障定位方法分为行波法和故障分析法,并分别总结两类方法的优缺点,最后针对当下柔性直流输电线路的故障定位研究现状给出了一些建议。
Flexible DC transmission lines are long and prone to failure.In order to improve line reliability,accurate and reliable fault location techniques are needed.This paper summarizes the research status of fault location of flexible DC transmission networks at home and abroad,and classifies the fault location principle.It divides the fault location method of DC transmission lines into traveling wave method and fault analysis method,and summarizes the advantages of the two methods.Disadvantages,finally put forward some suggestions and prospects for the current research status of fault location of flexible DC transmission lines.
