Method for realizing reliable power supply of multiple power supplies and multiple buscouple

The invention provides a method for realizing reliable power supply of multiple power supplies and multiple buscouple, which comprises the following steps of: in an initialization stage, reading a topological structure diagram of a target system, and determining configuration parameters and system layout corresponding to the target system; according to the system layout corresponding to the target system, determining a power supply layout position, a load layout position, a bus tie switch layout position and the like in the target system; in a power supply stage, reading each target load identifier, and sequentially determining an optimal power supply control mode of each target load according to the load priority of the target load and the like; determining whether there is a conflict between the optimal power supply control modes of the target loads, if there is a conflict, determining that the optimal power supply control mode corresponding to the target load with low load priority is an invalid power supp
