A train power supply system and method, and a train and a computer-readable storage medium. The train power supply system comprises a control module, a power supply input module, a precharge module, a rectifier module, a power supply output module, and a direct-current return module. The precharge module comprises a direct-current precharge module and an alternating-current precharge module; the control module is used for controlling the on/off state of a contactor in the power supply input module according to the current grid voltage working condition, so that the power supply input module outputs power corresponding to the current grid voltage working condition to the precharge module and the power is output by the precharge module; the rectifier module is used for converting the alternating-current power output by the alternating-current precharge module into direct-current power; the power supply output module is used for output the direct-current power output by the direct-current precharge module or the direct-current power output by the rectifier module to each passenger train. Application to a variety of grid voltage modes can be implemented, and the power supply costs of a train can be effectively reduced.
