Abstract
A method for operating a wind power installation, the wind power installation including an aerodynamic rotor having rotor blades of adjustable blade angle, being controlled by an operation control system, and being configured to generate an installation power, comprises activating a blade-angle adaptation routine when an ice accretion situation occurs, when ice accretion on the rotor blades has been detected or is expected, modifying a collective blade angle of the rotor blades using the blade-angle adaptation routine to adapt the rotor blades to an altered aerodynamic situation caused by the ice accretion, in order to increase the installation power, and selecting an aerodynamically improved blade angle as a modified collective blade angle and specifying the aerodynamically improved blade angle as an iced-blade angle.
