    • During the normal operation of a commercial power supply, a quick current limiting/interrupting part (3) supplies power from the commercial power supply to a load via a DC reactor, while an auxiliary power supplying part (4) performs a PQ control in such a manner that both the active and reactive powers to be supplied to the load (9) are zero. Additionally, the responsiveness of the PQ control is set to be longer than the accident detection period of the commercial power supply in an accident detecting part (2), thereby causing the auxiliary power supplying part (4) to supply power to the load (9) and an accident point without any instantaneous interruption until the accident detecting part (2) detects the accident. Moreover, the impedance of the DC reactor (14) is set to be equal to or greater than (100Z)/A, thereby inhibiting the voltage of the load (9) from being below an allowable voltage drop rate during the accident. If any power supply accident is detected by the accident detecting part (2), then the PQ control by the auxiliary power supplying part (4) is halted, and the interruptions by quick switches (13a,13b) are done.
    • 在商用电源的正常运行中,快速限流/中断部分(3)通过DC电抗器将商用电源供电给负载,而辅助供电部件(4)执行PQ控制 要提供给负载(9)的有功功率和无功功率都为零的方式。 此外,PQ控制的响应性被设定为比事故检测部(2)中的商用电源的事故检测时间长,从而使辅助供电部(4)向负载(9)供给电力 )和事故点,直到事故检测部分(2)检测到事故为止,没有任何瞬时中断。 此外,直流电抗器(14)的阻抗被设定为等于或大于(100Z)/ A,由此在事故期间将负载(9)的电压抑制在允许的电压下降率以下。 如果事故检测部(2)检测出任何电源事故,则停止由辅助供电部(4)进行的PQ控制,并通过快速开关(13a,13b)进行中断。
