The invention discloses a graph theory-based physical structure description method for a traction substation group through power supply system. The method comprises the following steps of: firstly, acquiring physical structure information of the traction substation group through power supply system; and then topologically describing the physical structure of the traction substation group cut-through power supply system by using nodes and edges, finally establishing a corresponding mathematical model by using an adjacent matrix, and qualitatively analyzing the power supply reliability of the traction substation group cut-through power supply system in different traction network and downlink connection modes. According to the method, the complex power supply physical structure of the traction substation group cut-through power supply system can be topologized and mathematical-modeled by using the nodes and the edges, so that a simpler and more efficient research means is provided for later argumentation and analysis of key indexes such as power supply reliability and operation economy of the traction substation group cut-through power supply system; and a simpler and more complete mathematical model of the topological structure of the traction substation group cut-through power supply system is provided for railway departments.

    一种基于图论的牵引变电所组群贯通供电系统的物理结构描述方法,包括如下步骤:首先获取牵引变电所组群贯通供电系统物理结构信息;然后用节点与边对牵引变电所组群贯通供电系统物理结构进行拓扑化描述,最后利用邻接矩阵建立相应的数学模型,并对不同牵引网上、下行连接方式的牵引变电所组群贯通供电系统的供电可靠性做了定性分析。本发明能够使用节点和边将牵引变电所组群贯通供电系统复杂供电物理结构拓扑化、数学模型化,为后期对牵引变电所组群贯通供电系统供电可靠性、运行经济性等关键指标的论证和分析提供一种更为简洁高效的研究手段,为铁路部门提供更加简单、完善的牵引变电所组群贯通供电系统拓扑结构数学模型。
