 A network describing incident matrix that depicts topology connection between distribution feeder sections and switches is introduced. Based on the model an algorithm is presented to locate faulty sections in distribution feeder network. It locates faulty sections directly and decides simultaneously which switches on the power source side should be cut off to isolate them. It also works for faults at branch ends of distribution network. Its program design is simple and further meets the need of realtime fault...

The program design for the method is very simple,it further meets realtime performance need for fault location. In addition,the algorithm can also be extended to systems with multipower sources and complex faults,which is proven to be correct by example calculations.  提出了一种反映馈线区域和开关设备拓扑联接关系的网络关联描述矩阵模型,并给出了基于这一模型的馈线故障区域定位的新方法,可直观地定位出故障区域且同时能确定出隔离该区域所应断开的电源侧开关,对分支末梢区域故障也同样适用。此算法程序设计简单,能满足故障定位的实时性要求,并可推广至多电源复故障系统。算例证明了此算法的正确性。  The problems exiting in current fault location algorithms for distribution networks are analyzed.In view of the network describing incident matrix that depicts topology connection between distribution feeder section and switches,an improved general matrix algorithm is presented.On the basis of general matrix algorithm,this paper gives a new criterion for the problem of the end faults,multipower sources and complex faults.It locates faulty sections quickly and decides simultaneously which switches on the power...
