摘　　要：为了有效地提升配电网故障分析和定位的效率,降低经济成本,论文对多种故障原因进行了深度的分析并提出了一种基于Lambda算法的配电网故障定位技术。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,可以有效地降低不同模糊度之间的相关性,极大地减少迭代和搜索次数,提升配电网故障定位效率。To effectively improve the efficiency of distribution network fault analysis and location,reduce economic costs,this paper conducts an in-depth analysis of a variety of fault causes and proposes a fault location technology of distribution network based on Lambda algorithm.The algorithm analyzes the data uploaded by the faulty distribution network and feeder terminal,and uses efficient fuzzy search technology to quickly locate the fault location.Experimental results show that using the proposed Lambda-based fault location technology of distribution network can effectively reduce the correlation between different ambiguities,which could greatly reduce the numbers of iterations and search times of the algorithm,and improve the efficiency of fault location in the distribution network.
