摘　　要：针对单电源配电网馈线单一故障问题,在对配电网结构有向描述的基础上,提出了一种反映配电网分层拓扑结构的有向分层拓扑模型,并给出了基于这一模型的馈线故障区域定位的新算法。该算法不仅可以方便、直观地定位出故障区域,还能同时确定出隔离故障所应断开的电源侧开关。算法计算简单,便于编程实现,能充分满足故障定位的实时性要求,可推广应用于多电源复杂配电网故障系统。算例证明了该算法的正确性和可行性。Aiming at the single failure problem of the feeder in single power source distribution network, on the basis of directed description of the power distribution network, the direction hierarchical topology model reflecting hierarchical topological structure of distribution network is proposed, and the new algorithm for fault area positioning for feeder based on this model is given. The algorithm can locate the fault area easily and visually, and to determine the switch that shall be discounted for isolating the fault. The algorithm is simple, ease to be programmed, and fully meets the real time requirement, it can be promoted to the fault system for complex power distributed network with multiple power suppliers. The example verifies the correctness and feasibility of this algorithm.
