０引言我国广大城乡１０ｋＶ配电网大部分采用辐射式供电系统，其电网为树枝状，设备沿线路分布，分散性较大。一旦某处发生故障，靠动用人力在方圆几千米甚至十几千米范围内查找，往往难以找到故障点，造成停电时间长、停电涉及范围大，对用户造成严重影响。针对配网现存... 0 Introduction Most of our urban and rural 10kV distribution network using radiated power supply system, the power grid is dendritic, equipment distribution along the line, decentralized. Once somewhere a breakdown, rely on human use in a radius of several kilometers or even ten kilometers to find, it is often difficult to find the point of failure, resulting in a long power outage, power outages involve a wide range of users have a serious impact. For distribution network existing ...
