摘　　要：为准确、快速地定位配电网(DN)中发生单相接地故障(SPGF)的线路区段并进行故障隔离,需要对所发生SPGF的特征进行理论分析,在此基础上研究配电线路SPGF的定位方法。将Matlab仿真技术应用于DN故障定位仿真教学、课程设计和课题研究,通过调整各种仿真参数,可对各种不同的故障定位方法进行仿真分析、验证和对比。DN故障定位仿真研究有利于加深学生对DN故障定位的理解。When distribution network(DN)is attacked by single-phase grounding faults(SPGFs),for the purposes of locating these SPGFs accurately and rapidly and isolating them from non-fault distribution lines,it is necessary to theoretically analyze characteristics of SPGFs firstly,and then SPGF location methods should be researched based on these characteristics.By applying Matlab simulation technology to the simulation teaching,curriculum design and research of SPGF location,various SPGF location methods can be analyzed,verified and compared with each other by adjusting their parameters.The simulation study of SPGF location is useful for deepening students’understanding of SPGF location.
