Generating capacity prediction method, device and equipment of wind power station and medium

The invention discloses a generating capacity prediction method and device of a wind power station, equipment and a medium, and belongs to the field of wind power generation. The method comprises the following steps: acquiring station information of a wind power station, wherein the station information comprises station position data, station actually-measured wind speed data and station actually-measured power data; according to the station information of the wind power stations, determining a target wind power station set meeting correlation conditions with the target wind power stations; obtaining reanalysis data information of the target geographic grid point in the first long-term duration, and predicting predicted wind speed data of the target wind power plant station in the future second long-term duration by using a time sequence algorithm based on the reanalysis data information or based on the reanalysis data information and the station information of the target wind power plant station; and utilizi
