摘　　要：为充分发挥日益完善的馈线自动化硬件系统的功能来达到迅速判断隔离配网故障区域的目的 ,算法采用变结构耗散网络配网模型 ,将配电网的开关看作图的顶点 ,将其馈线看作图的弧 ,并将流过开关的电流当作顶点的负荷 ,将馈线供出的负荷 (即接于该馈线的配电变压器供出的负荷 )当作弧的负荷 ,通过合理配置配电监控终端快速构成配网归一化负荷矩阵 ,从而进行过热弧搜索以有效地解决配电网络故障区段的判断和隔离问题。实践结果表明使用本算法能快速有效地达到目的。同时给出了算法中关键模块的程序框图 。For the sake of utilizing the function of the hardware system in the FA(Feeder Automation)to judge and isolate fault section rapidly, based on structure variable dissipated network model,the algorithm consideres distribution network as a graph,so it regards the switches as vertexes and regards the feeder lines as arcs.The current flowed through the switches is defined as the load of the vertexes,and the supply of the feeder lines is defined as the load of the arcs.By configuring FTU reasonably we can format the unitary load matrix of distribution network quickly,so we can search for the over-heated arcs based on the matrix.With this,we can judge and isolate the fault sections in distribution system effectively.Program flow about the key modules are provided and discussed in the mean time,we also describe the detailed structure of the sparse matrix in the algorithm.
