Abstract: A power control device is provided which can execute self-sustaining operation only when conditions for allowing the self-sustaining operation are satisfied reliably, so as to supply AC power to a power load connected with a power system before the self-sustaining operation.In a case where an instruction to change the power control device into the self-sustaining operation state is accepted, the inverter is connected with the loads by the disconnection relay and the self-sustaining operation is started when voltage to be applied to a wiring portion between the disconnection relay and the earth leakage breaker is not detected, when current flowing between the main breaker and the power system is not detected and when a contact signal indicative of the open/close state of the main breaker indicates an open state. Moreover, the inverter is disconnected from the power system by the disconnection relay and the self-sustaining operation is stopped when the power control device is in the self-sustaining operation state in addition to that current flowing to or from the power system is detected or to that a contact signal indicative of the open/close state of the main breaker indicates a close state.
