ABSTRACT:
A grid interconnection device includes a relay controller configured to control separation or interconnection of a relay; a receiver configured to receive, from a predetermined transmission path, power failure information containing at least local area information indicating an area in which a power failure occurs; a determination unit configured to determine an occurrence of a power failure in a power distribution system, when the power failure information includes local area information of an area to which the power distribution system belongs; and a detector configured to detect an islanding state. The detector increases detection sensitivity of the islanding state when the determination unit determines the power failure in the power distribution system. The relay controller performs separation control for the relay when the islanding state is detected by the detector.
