Abstract
Method for de-icing at least one rotor blade of a rotor of a wind power installation, wherein the rotor is able to be operated at a variable rotating speed and the wind power installation generates an output from wind, said method comprising the following steps: checking for an icing situation on the at least one rotor blade, and changing from a normal operation of the wind power installation without de-icing to a de-icing operation if an icing situation has been identified; wherein in the de-icing operation the at least one rotor blade is heated for de-icing, and the rotating speed and/or the generated output are/is reduced as a function of at least one environmental condition of the wind power installation; wherein the at least one environmental condition is selected from the list including an external temperature of the wind power installation and a wind speed in the region of the wind power installation.
