It is sent to the device 12 and its output is adjusted. Thus, after the output of the inverter device 12 is synchronized with the system power supply 29 and the parallel operation is started, the division switch 26 is turned on. Further, the interconnection operation control signal is adjusted to gradually reduce the output current of the inverter device 12, and the load is transferred from the power supply vehicle 16 to the system power supply 29. When the output current of the power supply car 16 (detected via the current transformer 20) becomes zero, the system load 15 receives power only from the system power supply 29. As described above, the uninterruptible switching back (power recovery) is completed, the live line connection cable 28 and the clamp type voltage / current detector 24 are removed, and the construction work is completed.
