Power network topological relation construction method based on IEC61970 standard

The invention discloses a power network topological relation construction method based on an IEC61970 standard. The method comprises a step of numbering nodes, switches and branches in a power network wire connection diagram, a step of defining the relevant variable of the electric equipment in a power network and associating the connection node of the variable to a corresponding topological logical node, a step of outputting the associated topological logical nodes and constructing a topological logical node matrix according to the topological logical nodes, and a step of traversing the electrical equipment in the power network and drawing a topological wire connection diagram according to the topological logical node matrix. According to the method, a standard and open power system information model is established, the interoperation is promoted, the cost of production and maintenance is reduced, and the reliability of the system is improved greatly. 本发明公开了种基于IEC61970标准的电力网络拓扑关系构建方法，包括以下步骤：对电力网络接线图中的节点、开关和支
