  • Patent number: 12398693
    Abstract: The present disclosure relates to methods (100, 200, 300) for controlling a wind turbine (10) during a yaw operation. The present disclosure further relates to control systems (92) for wind turbines and to wind turbines (10). A method for operating a wind turbine (10) during yaw operation comprises operating one or more yaw drives (35) to rotate the nacelle (16) with respect to the tower (15). In addition, the method comprises predicting an end of the yaw operation and, in response to predicting an end of the yaw operation, actuating a hydraulic brake (94) before the predicted end.
    Type: Grant

  • Patent number: 10167848
    Abstract: The invention relates to a method and a system for monitoring an individual blade adjustment of a wind turbine which includes a tower, a rotor which is arranged on the tower and has at least two rotor blades whose blade angle can be adjusted individually, and a blade adjustment system, wherein the blade adjustment system includes a blade controller and sensors for sensing individual actual blade angles of the at least two rotor blades, wherein an individual blade controller is included which receives a collective set point blade angle from the blade controller and which actuates at least two rotor blades with respectively individual set point blade angles, as well as a corresponding wind turbine.
