摘　　要：小电流接地系统在我国配电网中应用比较广泛,也是最易发生单相接地故障的系统,因此如何及时检测和判别故障线路一直是配电网自动化研究的一个课题。文中根据国内外对小电流接地系统单相接地故障选线方法的各种典型选线方法做出了归纳,提出了现今研究的难点和研究的方向。Small current grounding system applied in domestic distribution network more widely and also the most prone to single-phase ground fault of the system, so how timely detect and distinguish fault line has always been a topic of power distribution automation research. A brief review of small current grounding system at home and abroad on the status of research and the various existing classic line selection made the induction and presented the current research problems and research directions.
