Abstract
A method for operating a wind turbine includes determining a current temperature of a rotor blade and activating and deactivating a rotor blade heating device in dependence upon the determined current temperature. The current temperature is determined by assuming a temperature starting value and calculating a change in temperature taking into account at least one predefined characteristic variable for the temperature behavior of the rotor blade and at least one operating parameter of the wind turbine.
