摘　　要：非有效接地电网故障选线,是我国在建和改建的配电系统中亟待解决的重要课题。论文首先结合相关研究文献,整理了国内外选线方法的发展脉络,对现有选线方法进行了归纳;之后从单一判据故障选线方法、基于信息融合的故障选线方法及借鉴其他学科理论的选线方法三个视角展开综述,通过对比分析,概括了各方法的适用条件及优缺点,介绍了改进方案的最新研究成果;最后,对选线技术研究中存在的问题及未来的研究趋势进行了总结与展望。Fault line Selection in Non-Effective Earthed System is an important subject that need to be solved urgently under construction, rebuilding of the power distribution system. The thesis summarizing the existing line selection, from three angle of view including a single criterion fault line selection method, basing the information fusion fault line selection method and referencing the theory of other disciplines and location method launches review. And combined with domestic and international relevant research literature, developing the line selection method development venation, through the contrast analysis, and summarizing the method of applicable condition and advantages and disadvantages, introducing the latest research results of the improved scheme. Finally, this thesis summary and looks forward to the location of technical problems existing in the research and the future research trend.
