摘　　要：文中在考虑地区电网实际的基础上,对配电网生产管理系统、电网调度自动化系统、用户用电信息采集系统、气象信息系统以及全业务数据中心的配电网数据进行深度挖掘,提出了基于CIM的配电线路拓扑结构图重构方法,并提出了对中、低压配电网的现状自动进行诊断分析的具体思路和实施步骤。针对配电网存在的线路分段过多、网架冗余问题、供电半径过大等主要问题,提出了配电网自动诊断分析的具体方法及实施步骤。以某市电网进行实例计算分析,列举了配电网现状自动诊断分析结果,获得了与一流配电网目标之间的差距,验证了所提出的配电网现状自动诊断分析方法的有效性。On the basis of considering the actual situation of regional power grid,this paper excavates the distribution network data deeply,which are from the perspective of production management system,dispatching automation system,user power information acquisition system,meteorological information system and full-service data center of distribution network.Moreover,the reconfiguration method of distribution line topology based on CIM model and the automatic implementation of the status quo of medium and low voltage distribution network are put forward.The specific solution and implementation steps of diagnostic analysis are also discussed.In view of the main problems existing in the distribution network,such as too large power supply radius,too small line diameter,too many segments,redundancy of connection,etc.,the transformation measures of the specific problems are generated.And based on the calculation of power grid in one city,the results of automatic diagnosis and analysis of distribution network status are listed,and the gap between the targets of first-class distribution network is obtained the validity and feasibility of the proposed model and method are verified.
