The invention relates to an anti-flash system and method. The anti-flash system comprises an anti-flash device, a power transformation device and a charging station. The flash-proof device comprises a bidirectional AC/DC conversion circuit, an energy storage unit and a control unit. The bidirectional AC/DC conversion circuit is connected with the input end of the power transformation equipment, the bidirectional AC/DC conversion circuit, the energy storage unit and the control unit are mutually connected, the control unit is connected with the charging station, the input end of the control unit is connected with a power grid, and the power transformation equipment is connected with the charging station; the control unit is used for determining the power grid operation state according to the voltage information of the input end; and in response to determining that the operation of the power grid is in the abnormal state, issuing a first driving instruction to the bidirectional AC/DC conversion circuit so as to provide energy for the charging station through the energy storage unit. Therefore, when the power grid flashes or the voltage drops suddenly, energy can be provided by the energy storage unit, and electric energy can be uninterruptedly provided for equipment which is being charged in the charging station, so that the equipment in the charging station and the personal safety of personnel in the station are prevented from being damaged.
本公开涉及一种防闪断系统和方法。该防闪断系统包括防闪断设备、变电设备和充电站;防闪断设备包括双向AC/DC变换电路、储能单元、控制单元;双向AC/DC变换电路和变电设备的输入端连接,双向AC/DC变换电路、储能单元、和控制单元相互连接,控制单元与充电站连接,输入端与电网连接,变电设备与充电站连接;控制单元用于根据输入端的电压信息,确定电网运行状态;响应于确定电网运行处于异常状态,向双向AC/DC变换电路下发第一驱动指令,以通过储能单元为充电站提供能量。如此,在电网闪断或电压骤降时,可以由储能单元提供能量,不间断地为充电站内正在充电的设备提供电能,以防止给充电站内设备及站内人员人身安全带来伤害。
