Problems solved by technology

[0003] At present, wind farms usually use the numerical weather prediction data provided by the Meteorological Bureau to predict wind power. Due to the influence of factors such as the height field at the wind farm site, the eddy current generated by the topography, the orientation of the wind turbines, the wake flow between the wind turbines, etc., there are deviations from the predicted wind data provided by the Meteorological Bureau.
It can be seen that the numerical weather forecast provided by the Meteorological Bureau cannot accurately predict the wind force of the wind farm.

Abstract

The invention relates to a method and a device for predicting wind power, which can accurately predict the wind power of a fan in a wind farm. The method comprises steps: according to historical numerical weather prediction data and historically-measured wind power data measured for the fan in the wind farm, a wind power prediction model corresponding to the fan is built, wherein the numerical weather prediction data comprise at least one selected from a wind speed, air pressure, a wind direction and an air density; and according to the numerical weather prediction data and the wind power prediction model, the wind power of the fan is predicted.

Description

technical field [0001] The present disclosure relates to the field of wind power generation, and in particular, to a wind power prediction method and device. Background technique [0002] The wind power prediction of the wind farm is one of the most important means to guide the operation of the wind farm. Through the wind power prediction, the power generation of the wind farm can be predicted, and the operation decision of the wind farm can be assisted, etc. [0003] At present, wind farms usually use the numerical weather prediction data provided by the Meteorological Bureau to predict wind power. Due to the influence of factors such as the height field at the wind farm site, the eddy current generated by the topography, the orientation of the wind turbines, the wake flow between the wind turbines, etc., there are deviations from the predicted wind data provided by the Meteorological Bureau. It can be seen that the numerical weather forecast provided by the Meteorological...
