METHOD TO CONTROL THE OPERATION OF A WIND ENERGY INSTALLATION, INCLUDING GENERATING A 3D WIND SPEED MODEL, AND WIND ENERGY INSTALLATION

摘要

The invention relates to a method to control the operation of a wind energy installation. Different wind speeds of the wind in front of the wind energy installation are measured in a given predetermined measurement volume. Data are gathered, which reflect the measured wind speeds. The data are used to generate a three-dimensional wind speed model. The three-dimensional wind speed model is used to predict a wind speed change at the wind energy installation in reference to a predetermined point of time. A control command is generated based on the predicted wind speed change and based on an actual wind speed, which is measured at the wind energy installation. The control command is used to control the operation of the wind energy installation.
