Satellite ground power supply system and method for rapid fault self-inspection

The invention relates to a satellite ground power supply method for rapid fault self-inspection, and the method comprises the steps: measuring a load resistance value Rload through a wired station before the initial power-up of a satellite, and outputting a measurement result to an upper computer; if the load resistance value Rload is not lower than the resistance value lower limit Rmin, the upper computer controls the wired station to connect the power supply channel; after the upper computer controls the wired station to be connected with the power supply channel, the upper computer sets an output curve of a power supply and sets power supply output enabling; the wired station measures the voltage Vbus of the power supply channel and outputs a measurement result to the upper computer; the wired station measures the temperature Tch of the power supply channel and outputs a measurement result to the upper computer; the wired station monitors the output state of the wired instruction; when a wired instruction
