<P>PROBLEM TO BE SOLVED: To provide a power plant capable of performing reconnection in recovery quickly without giving stress to a generator and complexing the control in the short-time power failure of a system power supply. <P>SOLUTION: The power plant 100 supplies AC power to a load 106 in connection with the system power supply 120. When power failure is detected in the system power supply 120, a controller 111 allows an excess power consumer 107 to start consuming power, performs control so that the conversion operation of a DC/AC transducer 103 is stopped, reduces power supply to the excess power consumer 107 at a lapse of time when the recovery is detected within first prescribed time from the detection of the power failure, and restarts the conversion operation of the DC/AC transducer 103 for performing the control so that the conversion power of the DC-AC converter 103 is increased at a lapse of time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
