The invention discloses a high-power direct-current adjustable shore power charging system, and the system comprises a high-voltage incoming cabinet which is used for connecting a shore-based power supply system to receive a power supply voltage; the pre-charging cabinet is connected with the high-voltage wire inlet cabinet and is used for inhibiting current impact during power-on; the step-down transformer is connected with the pre-charging cabinet and is used for reducing the power supply voltage; and the variable-frequency power supply module comprises a controller and multiple groups of filtering and rectifying modules which are connected in parallel, and the controller is used for acquiring charging demand information of the to-be-charged ship and controlling the multiple groups of filtering and rectifying modules to rectify the alternating current from the step-down transformer into direct current to be transmitted to the to-be-charged ship according to the charging demand information. According to the high-power direct-current adjustable shore power charging system, the ship power supply device can be quickly charged, the charging time is shortened, and the charging efficiency is improved.
