Method and system for determining self-adaptive control bidirectional output high-power cathode protection power supply

The invention provides a method and a system for determining a self-adaptive control bidirectional output high-power cathode protection power supply. The method comprises the following steps: determining an interference level of a direct current grounding electrode on an oil-gas pipeline according to a direct current grounding electrode parameter, an oil-gas pipeline parameter and a soil parameter; and determining the optimal configuration parameters of the cathode protection power supply by adopting an adaptive control algorithm according to the number of the bidirectional output high-power cathode protection power supplies to be configured and the set target function and constraint condition of the cathode protection power supply optimal configuration. According to the method and the system, the bidirectional output high-power cathode protection power supply in the oil and gas pipeline is optimally configured, so that the design efficiency of the cathode protection system of the to-be-built/built pipeline i
