Abstract

The invention provides a method and device for correcting predicted wind speed of a wind farm. The correction method includes the following steps: respectively establishing a plurality of wind speed deviation matrices of existing wind farms, wherein the wind speed deviation represents the difference between the predicted wind speed and the measured wind speed of the target wind measuring tower of the existing wind farm; The wind speed deviation matrix of the existing wind farm establishes a wind speed deviation correction model library, and the wind speed deviation correction model library includes a plurality of wind speed deviation correction models corresponding to the existing wind farm, wherein the wind speed deviation correction model represents the existing The relationship between the wind speed deviation and the equivalent factor of the wind farm; determine the relevant parameters of the target wind farm, and determine the matching wind speed deviation correction model in the wind speed deviation correction model library according to the relevant parameters, and then according to the determined wind speed deviation The correction model corrects the predicted wind speed of the target wind farm. The invention can effectively make up for the error of the existing fluid model when calculating the wind speed of the wind farm.

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...
