The invention relates to the power distribution device, the power distribution system and the power distribution method, and the power distribution device comprises power distribution transformation equipment, AC/DC conversion equipment, an acquisition circuit and a processing module. The acquisition circuit acquires the total current, and the processing module controls the AC/DC conversion equipment to perform AC/DC conversion according to the total current when the load of the power distribution network does not exceed the preset load so as to realize DC power supply; and when the load of the power distribution network exceeds the preset load, controlling the AC/DC converter equipment to stop AC/DC conversion so as to stop DC power supply. According to the power distribution device provided by the invention, the load pressure and burden of the power distribution network can be reduced, and a load peak eliminating effect is achieved; and for charging equipment implementing a peak-valley electricity price system, charging at an electricity utilization peak can be avoided, the charging cost is reduced, a load valley filling effect is achieved, and the optimal social benefit is achieved.

    本申请涉及一种上述配电装置、配电系统及配电方法,其中,所述配电装置包括配电变压设备、AC/DC换流设备、采集电路和处理模块。通过所述采集电路采集所述总电流,所述处理模块根据所述总电流,在所述配电网的负荷未超过所述预设负荷时,控制所述AC/DC换流设备进行交直流转换,以实现直流供电;在所述配电网的负荷超过所述预设负荷时,控制所述AC/DC换流设备停止交直流转换,以停止直流供电。本申请提供的所述配电装置不仅可以减小配电网的负载压力和负担,具有负荷消峰作用;而且对于实行峰谷电价制度的充电设备来说,可以避免在用电高峰充电,减小充电成本,具有负荷填谷作用,实现社会效益最优。
