摘　　要：地理信息系统(Geographic Information System,GIS)中的拓扑结构与高压配电网的拓扑结构有一定差异,需要通过一定处理才能在GIS平台实现配电网的拓扑分析与供电路径分析。GIS平台通过和监控与数据采集(Supervisory Control And Data Acquisition,SCADA)系统交互实现配电网设备、线路状态的动态更新。提出通过边缘节点来连接位于不同图层的主站接线图和地理接线图;在此基础上,以母线节点为起点,通过从向下、平行、向上3个方向进行深度搜索,站内以节点为主,地理接线图中以线路为主,最终完成供电路径的全部搜索,实现高压配电网供电路径的在线分析,并通过专题图将分析结果清晰显示在GIS平台上。Due to the topology difference between the geographical information system（GIS） and distribution network, the analysis of topology or power supply paths of distribution network can’t be realized directly in the GIS platform. The dynamic updating of the distribution network equipment and lines state is achieved through the interaction between GIS platform and supervisory control and data acquisition（SCADA） system. This paper puts forward a method of connecting the substation wiring diagram and geography wiring diagram in different layers through edge node. Starting at the bus nodes, from the downward, parallel and upward directions, the searching of all supply paths is conducted, path analysis inside the station is node-based and path analysis of geography wiring diagram is line –based. On-line analysis of supply path in high voltage distribution network is realized through the searching of all supply paths. The result of on-line analysis can be displayed clearly by the thematic map in the GIS platform.
