摘要
根据基于图论的故障定位的改进矩阵算法,本文分析了当前配电网故障定位算法中存在的问题。对于配电网不同线路上的多重故障及末端故障问题,依据该配电网故障判断算法,提出了切实可行的判据。本算法不仅可以用于对配电网的单一故障进行定位,同时也可以用于对配电网末端故障或不同线路的多节点故障做出快速、准确的诊断。最后通过对南水电厂的配电网进行精简后,模拟计算了三电源配电网多出线的各种故障,结果表明了该判据的有效性。
According to the improved matrix algorithm for fault location based on graph theory, this paper analyzes the problems existing in the fault location algorithm for distribution network. For the problem of multiple faults and terminal faults on different lines in distribution network, a feasible criterion is put forward based on the fault diagnosis algorithm of the distribution network. This algorithm can not only be used to locate the single fault of distribution network, but also can be used to make fast and accurate diagnosis to the terminal fault or multi node fault of different lines. Finally, it is simpli- fled as a simple distribution network about Nanshui Hydropower occurred in a distribution network consisting of three source and sults show that the presented criterion is effective. Station. The simulation and calculation of various faults multi-outgoing lines are carried out. The calculation results show that the presented criterion is effective.
