Distribution Network Topology Modelling and Automatic Mapping Based on CIM and GIS

This paper introduces the spatial information technology of geography information (GIS) to implement the modelling of distribution network and dynamic topology relationships at the context of topology modelling specifications of Common Information Model (CIM). On the basis of the data model, this paper aims to establish an automatic mapping system oriented to the one-line electrical connection diagram. As a result, a simple and reliable thematic mapping algorithm is constructed oriented to satisfy the key technical requirements of distribution network mapping, including scientific layout of thematic map, wiring aesthetics and avoiding crossover. The given algorithm of topology model and automatic thematic mapping are applied and verified in a geographic information management system implemented by the Foshan Power Supply Bureau. The results show that the system can real-time and accurately present the attribute data of distribution network equipment, spatial data and important operating parameters.
