The　location　of　the　faulty　section　of　the　distribution　network　is　the　prerequisite　for　the　fault　isolation　and　power　supply　restoration　of　the　distribution　network.　Therefore,　studying　the　location　of　the　faulty　section　of　the　distribution　network　is　of　great　significance　to　improve　the　reliability　of　the　power　supply　of　the　distribution　network.　Firstly,　the　methods　for　locating　fault　sections　in　domestic　and　foreign　distribution　networks　are　summarized　and　classified.　Then,　according　to　the　different　types　of　faults,　the　section　location　methods　for　large　current　faults　and　small　current　faults　in　the　distribution　network　are　introduced　respectively.　Among　them,　the　basic　principles,　advantages　and　disadvantages,　and　development　process　are　analyzed.　Finally,　combined　with　the　development　trend　of　the　distribution　network,　the　future　research　on　the　fault　location　technology　of　the　distribution　network　is　prospected.　©　2021　IEEE.
