摘要
为解决矩阵算法不能正确判断末梢故障及节点过多时运算速度慢的弊端,根据配电网络结构特点,提出了一种基于树形搜索的配电网故障区域检测、隔离及恢复实用算法。该算法基于各开关联络关系构造出配电网树形模型结构,利用配电自动化终端采集的故障信息搜索出了故障区域,并找出了多重供电恢复方案。最后由算例表明,该配电网故障定位、隔离和恢复算法是高效和可行的。
Aiming at solving the abuse of matrix algorithm that couldn＇t correctly judge fault occurred in frontier node of distribution network and calculate slowly when had too many nodes, a practical algorithm of fault location, isolation and restoration of distribution system on the basis of distribution network characteristics based on a searching tree was proposed. The algorithm constructed tree models of distribution network based on switch interconnection relations, searched out fault area using fault information collected by FTUs and DTUs and found out a multiple power restoration scheme. Finally, the simulation results indicate that the algorithm is effective and feasible.
