Design method and device for optimal communication path of transformer substation, terminal and medium

The invention discloses a design method and device for an optimal communication path of a transformer substation, a terminal and a medium, and the method comprises the steps: obtaining a communication network topological structure of a hierarchical protection system, a transformer substation node, the repair rate of the path, the fault rate of the path, the communication flow on the communication path, and the communication capacity on the communication path, and taking the obtained data as to-be-tested data; constructing a target function according to target parameters and weights of the target parameters, wherein the target parameters comprise delay of a communication path, network reliability and a network utilization rate; inputting to-be-tested data into the objective function, solving by using a genetic algorithm to obtain an optimal communication path between every two substations, and then performing combining to obtain an optimal communication path set of the hierarchical protection system.
