Abstract
The objective of the present invention is to reduce erroneous detection of arcs, and to reduce erroneous responses concomitant with erroneous detection. In a photovoltaic power generation system (), a main control part () controls an arc detecting device () in such a way as to suspend arc detection during periods in which arc-like noise is being generated. Examples that can be cited of periods during which arc-like noise is generated include a period from when a PCS () starts up to when the supply of power to a power grid () begins, and a period during which a current (I) flowing from a power generating device () to the PCS () is changing suddenly.
