A management device (1000) for managing a plurality of wind power generation devices (1) each installed at a different place specifies wind power conditions around the wind power generation devices (1) on the basis of wind power state data transmitted from each of the wind power generation devices (1), determines from the specified wind power conditions whether operation status data transmitted from each of the wind power generation devices (1) is normal or not, and outputs the results. This provides a wind power generation device management system capable of accurately determining, at a remote location, the abnormality of each of the wind power generation devices installed at various places.
