The invention relates to the technical field of electric ship power supply, in particular to a ship power supply control method, system and device and a medium. Acquiring total current information of connected alternating current equipment on the ship; under the condition that the alternating current charging state information is accessed, a PWM duty ratio signal is obtained, power supply current is matched according to the PWM duty ratio signal, and maximum power supply information is obtained; and charging quantity analysis is performed according to the total current information and the maximum power supply information to obtain charging threshold instruction information for limiting the charging power of the shipborne charger, so that the conversion cost from direct current to alternating current is reduced while the electric ship operates efficiently.

    本申请涉及电动船舶供电技术领域,尤其是涉及一种船舶供电控制方法、系统、设备及介质,包括:获取交流充电状态信息;获取船舶上已接通交流设备的总电流信息;在交流充电状态信息为已接入的情况下,获取PWM占空比信号,根据PWM占空比信号匹配供电电流,得到最大供电信息;根据总电流信息和最大供电信息进行充电量分析,得到用于限制船载充电器充电功率的充电阈值指令信息,使得在电动船舶高效运作的同时,降低直流电至交流电的转换成本。
