To conduct uninterruptible construction operation, without having to use a large engine generator vehicle and by using a power supply vehicle which is small, which is superior in terms of an environmental aspect and whose power is generated by an inverter, with reference to a house to which the construction operation is to be performed and whose load amount is large.

A master power-supply vehicle 16 and a slave power-supply vehicle 17, which electrify the house 2 to which the construction operation as a distribution construction operation is to be performed, are provided with DC/AC converters 26, 27 which convert DC power supplies 18, 19 into AC power supplies by an inverter operation. The vehicles 16, 17 are provided with their drive and control devices 28, 29. At the device 18 in the power-supply vehicle 16, a means which forms phase information on the voltage control of the AC power supplies is installed, a means, which controls the output voltage of the converter 26 in an own vehicle to the phase of the phase information is installed, and a means which outputs the phase information to the device 29 in the power-supply vehicle 17 via a wired or radio transmission line is installed. At the device 29, a means which fetches the phase information in the transmission line is installed, and a means by which the output voltage of the converter 27 in the own vehicle is controlled to the phase of the phase information is installed.
