The bidirectional chopper (2) selectively performs a charging operation for storing the DC power received from the DC bus lines (L1, L2) in the power storage device (7), and a discharging operation for outputting the DC power of the power storage device (7) to the DC bus lines (L1, L2). The inverter (3) converts DC power received from the DC bus lines (L1, L2) into AC power and supplies the AC power to the load (8), and converts regenerative power generated by the load (8) into DC power and outputs the DC power to the DC bus lines (L1, L2). An SOC reference value that is smaller than the upper limit value of the usable range of the SOC and larger than the lower limit value of the usable range is set for the power storage device (7). When the AC power supply (6) is normal, the control device (5) controls the bidirectional chopper (2) so that the SOC of the power storage device (7) becomes the SOC reference value. When the AC power supply (6) is powered off, the control device (5) controls the discharge operation in accordance with the power operation of the load (8) and controls the charge operation in accordance with the regeneration operation of the load (8) on the basis of the usable range.

    双向斩波器(2)选择性地执行将从直流母线(L1、L2)接收的直流电力蓄积于蓄电装置(7)的充电动作与将蓄电装置(7)的直流电力向直流母线(L1、L2)输出的放电动作。逆变器(3)将从直流母线(L1、L2)接收的直流电力转换为交流电力并向负载(8)供给,将负载(8)产生的再生电力转换为直流电力并向直流母线(L1、L2)输出。对于蓄电装置(7)设定了比SOC的可使用范围的上限值小并且比可使用范围的下限值大的SOC基准值。在交流电源(6)正常时,控制装置(5)控制双向斩波器(2)以使蓄电装置(7)的SOC成为SOC基准值。在交流电源(6)停电时,控制装置(5)基于可使用范围,与负载(8)的动力运转对应地控制放电动作,与负载(8)的再生运转对应地控制充电动作。
