Calculation method and device for improving prediction precision of generating capacity of wind power station and computer equipment

The invention provides a calculation method and device for improving the prediction precision of the generating capacity of a wind power station and computer equipment. According to the technical scheme, the method comprises the steps that geographic areas containing wind driven generators are obtained, the geographic areas are divided into grids according to the weather prediction capacity, and wind speed prediction value information in the grids, performance information of the wind driven generators in the grids and the actual generating capacity of the wind driven generators in the grids are obtained in sequence; the generating capacity prediction values of each wind driven generator in different time periods are calculated, and the generating capacity prediction values of all the wind driven generators in the grids in the same time period are superposed to obtain generating capacity prediction initial values; and actual generating values of the wind driven generators are acquired, the actual generating va
