Abstract

The invention provides a wind farm predicted wind speed correction method and a wind farm predicted wind speed correction device. The wind farm predicted wind speed correction method comprises steps that a plurality of conventional wind farm wind speed deviation matrixes are established, and wind speed deviations represent differences between the predicted wind speeds of the target wind measuring masts of the conventional wind farms and actual measured wind speeds; based on the plurality of conventional wind farm wind speed deviation matrixes, a wind speed deviation correction model database is established, and comprises a plurality of wind speed deviation correction models corresponding to the conventional wind farms, and the wind speed deviation correction models represent relations between the wind speed deviations of the conventional wind farms and equivalent factors; related parameters of a target wind farm are determined, and according to the related parameters, the matched wind speed deviation correction model is determined in the wind speed deviation correction model database, and then the predicted wind speed of the target wind farm is corrected according to the determined wind speed deviation correction model. Errors generated during the calculation of the wind speeds of the wind farms by using conventional fluid models are effectively remedied.

Description

technical field [0001] The technical field of wind power of the present invention, in particular, relates to a method and device for correcting predicted wind speed of a wind farm. Background technique [0002] The simulation calculation of the wind speed of the whole wind farm is related to the selection of the model of the whole farm and the evaluation of the power generation, and also directly determines the economic benefits of the wind farm. As the development of wind farms is increasingly moving towards mountainous areas with more complex terrain and meteorological conditions, the deviation of wind speed and power generation of wind farms calculated by original fluid models, such as WT, Windsim, and WAsP, is also increasing. In some In wind farms, the calculation deviation of wind speed can even be as high as more than 20%, which brings huge economic losses to developers of wind farms. Contents of the invention [0003] The invention provides a method and device for...
