摘要： The present invention relates to a method for controlling heating of rotor blades (108) of an aerodynamic rotor (106) of a wind turbine (100, 100'), wherein, the heating of the rotor blades (108) is initiated, if icing of the rotor blades (108) is expected, wherein according to an icing criteria, if icing is expected is evaluated depending on a determined ambient temperature, a determined relative humidity, and a determined wind speed, each defining a determined weather parameter, and further according to the icing criteria, if icing is expected is evaluated depending on a temporal change of at least one of these weather parameters and/or of at least one other weather parameter.
