Control of a wind energy installation

A method of controlling a wind energy installation including a rotor that is rotatable about a rotor axis and which has at least one rotor blade, and a generator coupled to the rotor, the method comprising:

• detecting with at least one sensor a value of a forefield parameter that is present at a first point in time and in a first region located a first distance from the wind energy installation;
• and
• controlling with a computer at least one of the generator or at least one actuator of the wind energy installation on the basis of the detected forefield parameter value and a machine-learned relationship of at least one of:
• a predicted near field parameter at the wind energy installation,
• an operating parameter of the wind energy installation predicted for a later, second point in time,
• a control variable of the actuator, or
• a control variable of the generator,
• to the forefield parameter, or to a sequence of forefield parameter values.

A system for controlling a wind energy installation that includes a rotor that is rotatable about a rotor axis and which has at least one rotor blade, and a generator coupled to the rotor, the system comprising:

• at least one sensor configured for detecting a value of a forefield parameter that is present at a first point in time and in a first region located a first distance from the wind energy installation;
• and
• means for controlling at least one of the generator or at least one actuator of the wind energy installation on the basis of the detected forefield parameter value and a machine-learned relationship of at least one of:
• a predicted near field parameter at the wind energy installation,
• an operating parameter of the wind energy installation predicted for a later, second point in time,
• a control variable of the actuator, or
• a control variable of the generator,
• to the forefield parameter, or to a sequence of forefield parameter values.

A computer program product comprising a program code for controlling a wind energy installation that includes a rotor that is rotatable about a rotor axis and which has at least one rotor blade, and a generator coupled to the rotor, the program code stored on a non-transitory, machine-readable storage medium, the program code configured to, when executed by a computer, cause the computer to:

• detect with at least one sensor a value of a forefield parameter that is present at a first point in time and in a first region located a first distance from the wind energy installation;
• and
• control at least one of the generator or at least one actuator of the wind energy installation on the basis of the detected forefield parameter value and a machine-learned relationship of at least one of:
• a predicted near field parameter at the wind energy installation,
• an operating parameter of the wind energy installation predicted for a later, second point in time,
• a control variable of the actuator, or
• a control variable of the generator,
• to the forefield parameter, or to a sequence of forefield parameter values.
