将图论的概念引入了基于变电站拓扑互联供电块联络结构,遵循供电块联络模型构建基本原则,构建了四类基于任意数量变电站互联的典型供电块联络模型。在此基础上,定义了供电块联络模型的结构特性指标,并给出相应的计算方法。综合考虑各类供电区域对供电块联络模型的需求,结合匹配识别理论相关方法,分析供电区域与联络模型的匹配性,为不同供电区域合理供电块联络模型选择提供理论依据。文中所构建的供电块联络模型及匹配性分析方法将有助于提高配电网网络结构规划建设的规整性、合理性和科学性。

The graph theory was introduced for the power block contact based on topological connection between substations, and according to the basic principles of power block contact, four typical power block contact models with any number of interconnected substation were constructed. On this basis, the structural character indexes of power block model were defined, and the corresponding calculation methods were given. Then, considering various types and specific needs of power block contact areas, methods of matching recognition theory were used for match analysis between the area types and contact models, which provides the theory basis for different areas to choose appropriate contact models. The proposed construction models and match analysis will help to improve the regularity, rationality and scientificity of the distribution network construction and planning.
