一种配电网高可靠性接线模式和故障处理对策

A High Reliability Connection Mode and Fault Handling Countermeasure of Power Distribution Network

为实现对配电线路的最大化利用,解决配电网供电异常问题,文章以“某大型城市核心区配电网”为研究对象,结合最近8 a城市配电网可靠性数据,得出仅仅借助配电自动化系统提高供电可靠性,需要安装多个配电终端,无法满足实际应用需求。在参照基本“三双”接线模式的前提下,提出差异化“三双”接线模式和多线互为备用接线模式,该接线模式存在于理论构建阶段。以上3种典型“三双”接线模式进行逐步过渡和升级,从而提高其供电可靠性。希望通过研究,为相关人员提供有效的借鉴和参考。

In order to maximize the utilization of distribution lines,solve the problem of distribution network power reliability,this paper first to“a large urban core distribution network”as the research object,combined with the recent eight years city distribution network reliability data,only with the help of distribution automation system to improve power supply reliability,need to install multiple distribution terminal,cannot meet the demand of practical application.Secondly,on the premise of referring to the basic“three pairs”wiring mode,the differentiated“three pairs”wiring mode and the mutual standby wiring mode are proposed.This wiring mode exists in the theoretical construction stage.Finally,the above three typical“three pairs”wiring modes are gradually transferred and upgraded to improve the reliability of power supply.Hope that through this study,to provide an effective reference and reference for the relevant personnel.
