基于逻辑接口模型和子图同构的变电站二次回路自动设计研究

Research on Automatic Design of Substation Secondary Circuit Based on Logic Interface Model and Subgraph Isomorphism

为解决目前变电站二次回路因数字化设计水平低下,无法进行有效数字化移交,制约后续各环节高级应用发展的问题,提出一种基于逻辑接口模型和子图同构的二次回路自动设计方法。首先提出屏柜逻辑接口模型,用以描述对外功能区域、功能分组等全部设计信息;其次,按照逻辑接口模型提取间隔数据,构建相应拓扑图形,并建立典型数据模板库;为了实现对模板库的快速匹配,对图形匹配VF2算法进行改进,实现局部信息与模板库的子图同构判断;最后,根据数据模板快速匹配方法以及数据模板与逻辑接口模型的映射关系,实现二次回路的自动设计。

In order to solve the problem that the current digital design level of the secondary circuit of the substation is low,and it is unable to carry out effective digital handover,which restricts the development of advanced applications in subsequent links,an automatic design method of the secondary circuit based on logical interface model and subgraph isomorphism is proposed.Firstly,the logical interface model of the panel and cabinet is proposed,which describes all design information such as external functional areas and functional groups.Secondly,the interval data is extracted according to the logical interface model,the corresponding topological graph is constructed,and the typical data template library is established.Furthermore,in order to realize the fast matching of template library,the VF2 algorithm of graphic matching is improved to realize the isomorphism judgment of local information and template library.Finally,based on the fast matching of data template and the corresponding relationship between data template and logical interface model,the automatic design of secondary circuit is realized.
