  • Method and device for operating a wind turbine
    Patent number: 10612518
    Abstract: A method for operating a wind turbine includes: determining a value of a wind speed of an incident air mass at the wind turbine; if the determined value of the wind speed is greater than a first threshold value for the wind speed: reducing a rotational speed of a rotor of the wind turbine, and maintaining or increasing a generator torque acting upon the rotor; if the determined value of the wind speed is greater than a second threshold value for the wind speed, the second threshold value being greater than the first threshold value: reducing the rotational speed of the rotor, and reducing the generator torque acting upon the rotor.
