基于CIM的图形化电网拓扑建模与分析

CIM-based graphical power network topology modeling and analysis

网络拓扑是电力系统分析软件的基础,采用可视化的方法实现网络拓扑的建立是可视化能量管理系统的核心。文章基于CIM模型,建立了一个图形数据一体化的图形平台,该平台能够根据设备图元的端子坐标位置自动建立设备的连接关系,生成连接节点并编号。采用节点融合法实现拓扑分析,并按照分层次搜索策略进行拓扑的局部修正,该方法能减小搜索的范围,提高拓扑分析的速度,并具有很好的通用性和扩展性,易于编程实现。

Network topology is the basis of power system analysis software,and it is the core of visualized energy management system to establish network topology by visualized method.In this paper,based on common information model（CIM）,a graphic platform is built with the technology of graphic database integration.The platform can automatically establish the devices＇ connective relationship according to terminals＇ coordinates of device elements and create the connectivity node and its number.Topology analysis is implemented by using node merging law and the partial topology revision is carried out based on the strategy of searching in levels.The method can reduce the scope of searching and improve the speed of topology analysis.It has good versatility and extendibility and can be easily programmed.
