【摘要】 分析了目前配电网故障定位算法中存在的问题,根据故障定位的改进矩阵算法,针对配电网末端故障及不同线路上的多重故障问题,提出了切实可行的判据,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不同线路上的多重故障做出快速、准确的诊断。模拟计算了三电源配电网及单电源多出线的各种故障,结果表明了该判据的有效性。更多还原

【Abstract】 The problems exiting in current fault location algorithms for distribution networks are analyzed. Based on the improved matrix algorithm and according to the end faults occurred in distribution network and the multiple faults occurred in different lines, a feasible criterion is put forward by which not only the single fault occurred in distribution network can be located, but also the end faults and the multiple faults can be quickly and accurately diagnosed. The simulation and calculation of various faults occurred in a distribution network with three sources and the faults occurred in a distribution network consisting of single source and multi-outgoing lines are carried out. The calculation results show that the presented criterion is effective.更多还原
