Abstract (en)
[origin: WO2020083656A1] A method according to the invention for controlling a wind energy installation, which has a rotor (10), which can be rotated about a rotor axis (R) and has at least one rotor blade (11), and a generator (20) coupled to said rotor, comprises the steps of: - capturing (S10) a value of a forefield parameter, in particular a forefield wind parameter, which is present at a first time in a first region (A) which is at a first distance (a) from the wind energy installation, in particular the rotor blade, in particular a sequence of values of the forefield parameter up to the first time, with the aid of at least one sensor (40); and - controlling (S30) the generator and/or at least one actuator (12, 32) of the wind energy installation on the basis of this captured forefield parameter value, in particular this captured forefield parameter sequence of values, and a machine-learnt assignment of a predicted near field parameter, in particular a near field wind parameter, at the wind energy installation and/or an operating parameter of the wind energy installation predicted for a subsequent, second time and/or a control variable of the actuator and/or generator to the forefield parameter or forefield parameter sequences.
