Beschreibung
Zusammenfassung:	Provided is a linkage system switching technique in which when an abnormality has occurred in a power system linked to a power generation unit the unstable power system in which the abnormality has occurred is detached while power supply from the power generation unit is continued thereby contributing to the stabilization of the power system. The present invention is connected to a power control device (50) which is connected to a power generation unit (3) and a power system (1) and linked in accordance with a reference waveform generated on the basis of information inputted from the power system (1) and comprises: an abnormality detection unit (62) which detects the abnormality of the power system (1); and a connection switching unit (63) which when the abnormality detection unit (62) has detected the abnormality of the power system (1) switches information that is a generation source of the reference waveform to information from an auxiliary system (2) which is information different from information from the power system (1).
