摘要
为了提高配电网故障定位系统的运算速度和容错能力,提出了一种新方法,该算法采用独特的链表分析模式,首先以树枝为单位进行一次粗略定位查找故障所在的树枝,再根据树枝内节点间的链接关系,利用故障区域首末节点的信息不一致性完成二次精确定位;针对缺失数据的节点进行网络局部链接重构;通过一次定位和网络分叉区域节点之间的数据关系分析馈线终端单元可能上传的错误信息,讨论了可处理一点或多点故障的容错机制,并阐述了这些机制的纠错正确率。通过本文算法和传统矩阵法的复杂度对比及实际运行结果验证了算法的高效性和较强的容错能力。
For the improvement of the operation speed and the fault-tolerant ability of the distribution network＇s fault location, a new algorithm is proposed in this paper： Based on the chain table model, branch is taken for the unit to be used for the first location and searching the fault branch at the first. Then the data inconsistency between the head node and the end node could be used for the second location according to the link relation of the nodes in the fault branch; Local reconstruction is used to treat the nodes without data; The data correctness of each node is judged by the first location or the data relationship of the nodes in each furcation, on which some fault-tolerant mechanisms that could deal with one or more points fault and their correct rates are discussed. Actual operation results and the comparision of the complexity between present algorithm and the traditional matrix algorithm verify the high effectiveness and good fault-tolerant ability of this algorithm.
