摘　　要：针对目前配电网中大量接入分布式电源使得故障定位效率低下的问题,提出一种改进Lambda算法的配电网故障定位方法。该算法通过对出现故障的配电网络和馈线终端上传的数据进行分析,使用高效的模糊度搜索技术,快速定位出故障所在位置。实验表明,使用所提出的基于Lambda配电网故障定位技术对故障网络进行分析,能达到了模糊度间相关减小的要求,与此同时也减小了模糊度的搜索空间,极大地缩短了搜索的时间,提高了配电网故障定位效率。In allusion to trouble of inefficiency of breakdown location on account of a large number of distributed power sources in distribution network at present,an improved Lambda algorithm for fault location in distribution network is proposed.The algorithm analyzes the data uploaded by the faulty distribution network and feeder terminal,and employ high-efficiency ambiguity search science to speediness orientation the breakdown location.Experimental results demonstrates that employing the arranged Lambda-based fault location technology of distribution network can effectively reduce the correlation between different ambiguities,which could highly decrease amount of reiterations and seek times of the arithmetic,and increase efficiency of breakdown in orientation the distribution network.
