柔性配电网故障定位技术评述

Review on fault location technologyin flexible distribution network

为了使FDN安全可靠稳定运行,对柔性配电网(flexible distribution network,FDN)进行分析,但当FDN发生故障时进行故障的隔离和恢复存在很大困难,因此研究FDN故障定位技术具有重大的现实意义。首先对FDN的概念进行分析研究,对比传统配电网的运行方式闭环设计开环运行模式所存在的难题,对FDN的基础技术结合最新研究方向进行分析研究,传统配电网如何转变为FDN进行说明;然后文章总结研究传统配电网故障区段定位、故障定位;对故障区段定位、故障定位所涉及的主要研究方法进行分析,通过文献研究其适用范围和优缺点,并针对这些提出对应的建议,并结合上述分析,研究FDN故障定位技术和其所存在的缺陷以及未来所要研究的主要方向。最后指出当前柔性配电网和有源配电网研究主要存在的问题及未来研究的方向。

This paper analyzes the flexible distribution network(FDN),in order to make FDN safe,reliable and stable,it is very difficult to isolate and recover faults when FDN fails.Therefore,it is important to study FDN fault location technology.The practical significance.Firstly,the concept of FDN is analyzed and compared,and the problems existing in the open-loop design mode of the closed-loop design of the traditional distribution network are compared.The basic technology of FDN is combined with the latest research direction,and how the traditional distribution network is transformed into FDN.The paper summarizes the fault location and fault location of the traditional distribution network,analyzes the main research methods involved in fault location and fault location,and studies its application scope,advantages and disadvantages through literature,and proposes corresponding solutions.The recommendations,combined with the above analysis,study the FDN fault location technology and its shortcomings and the main directions to be studied in the future.Finally,the main problems of current flexible distribution network and active distribution network research and the direction of future research are pointed out.
