摘要
分析了目前配电网故障定位算法中存在的问题,针对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,提出了一种配电网故障定位的改进通用矩阵算法,该算法在通用矩阵算法的基础上,对配电网末端故障及多电源复故障问题提出了新的判据,可快速地定位出故障区域,同时能确定出隔离该区域所应断开的电源侧开关,不仅能对配电网单一故障进行定位,而且能对配电网末端故障以及多电源复故障做出快速、准确的诊断。该算法判据简单,通过算例证明了该判据的有效性。
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, multi-power sources and complex faults. It locates faulty sections quickly and decides simultaneously which switches on the power source side should be cut off to isolate them, Not only the single fault occurred in distribution network can be located, but also the end faults, multi-power sources and complex faults can be quickly and accurately diagnosed. The criterion of this algorithm is easy, which is proved to be effective by examples.
