摘　　要：针对含有分布式发电(DG)的配电网,把故障发生的位置分为"FTU设备之间"和"节点之间"两种,并据此提出了一种故障定位新算法。故障发生时,根据馈线终端单元(FTU)上传的故障电流方向信息,构建出故障信息矩阵,然后结合网络描述矩阵运行故障定位算法得到故障判断矩阵,最后根据故障判断矩阵判断出故障区段。算例分析验证了该算法的正确性。According to distribution network with distributed generations （DG）, fault always occurs among feeder terminal unit （FTU） equipment or among nodes, so a kind of new fault locating algorithm is proposed. When fault occurs, the fault information matrix is formed based on fault current direction information from FTU, then combining network describing matrix, fault judgment matrix is obtained by using of fault locating algorithm, by which fault section is determined finally. The correctness of algorithm is verified by examples.
