Abstract
A method an apparatus of automatically controlling a wind turbine re provided. of: A time-series of measurement values of the aerodynamic flow property of the wind turbine rotor blade is determined; a predictive wind field model representing a structure of a wind field acting on the wind turbine rotor blade is generated based on the time-series of measurement values, and a control value is generated based on the wind-field model.
Claims20
A method of automatically controlling a wind turbine, comprising:
- determining a time-series of measurement values of an aerodynamic flow property of a wind turbine rotor blade;
- generating a predictive wind field model representing a structure of a wind field acting on the wind turbine rotor blade based on the time-series of measurement values;
- generating, based on the wind-field model, a control value to produce a desired operational condition of the wind turbine rotor blade;
- and
- adjusting the wind turbine rotor blade according to the control value.
