Abstract
A method is provided for operating a wind turbine with a rotor having a rotor blade adjustable in its blade pitch angle. A generator is connected to the rotor and a measurement unit captures an actual value of a variable representative of a rotational speed of the generator. A set-point for a generator torque is provided and the set-point thereof is corrected. An actual value of a variable representative of a rotational speed of the generator is captured. A set-point for the torque as a function of the captured actual value is provided and the set-point for the torque as a function of a parameter for air density is corrected. A pitch angle value is captured and the set-point for the torque is increased when the captured value for the pitch angle exceeds a minimum value and has been corrected on the basis of an air density parameter.
