備。 A power receiving system and a private power generating system are operated in parallel, and a connecting circuit breaker is tripped to cut off the power receiving system by detecting that the power flow from the power receiving system to the private power generating system is reversed. A private power generation facility equipped with a power relay that operates to disconnect the load breaker includes a circuit that locks the connecting circuit breaker and a timer circuit that energizes the timer when the load breaker is operated. A private power generation facility characterized by comprising an electrical locking circuit that releases the lock.
