摘要
The method involves recognizing a net error (32) and determining a change in generator torque (28), and capturing a value for blade pitch angles (26, 27). A corrective value for the blade pitch angles is determined in dependence on the change of the generator torque and the value for the blade pitch angles. A set-point to be corrected for the blade pitch angles is determined from a rotational speed dependent set-point for the blade pitch angles at a regular operation and the determined corrective value for the blade pitch angles. An independent claim is also included for a wind power plant.
