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.
