Wind power prediction system and method based on meteorological data

The invention relates to the technical field of wind power generation, in particular to a wind power prediction system and method based on meteorological data. Comprising an obtaining unit used for obtaining meteorological data of a wind power plant in real time; the calculation unit is used for determining the wind power P of a plurality of fans in the wind power plant according to the meteorological data; and the processing unit is used for acquiring a plurality of pieces of historical meteorological data which are the same as the meteorological data through the historical meteorological database, and determining the future wind power of the plurality of fans in the future preset time according to the historical wind power W corresponding to the plurality of pieces of historical meteorological data. According to the method, the historical meteorological data and the real-time meteorological data are combined for comparison, different wind power efficiency levels are set according to the calculated power dif
