摘要
在基于公共信息模型(CIM)的配电网拓扑建模规范的基础上,研究了配电网设备的GIS数据建模方法以及空间连接逻辑关系;提出了基于GIS的专题图布局算法(单线图和系统图布局生成技术);并通过佛山市电力GIS建设对拓扑模型和专题图布局算法进行了应用和验证。结果表明,算法能满足专题图布局科学、布线美观和避免交叉等技术要求。
On the basis of the distribution network topology modeling principles provided by CIM, we discussed the GIS data modeling of distribution network equipment and their spatial logical connections at rst. And then, we provided a layout algorithm for the thematic map, including the generation technologies of the single line and system diagrams. Finally, we practiced and verified the topology data model and thematic map layout algorithm by implementing the Foshan power geographical information system. e results show that the algorithm can meet the key technical requirements, such as scientificfiayout of thematic map, clear wiring and avoiding crossover.
