Abstract

Wind turbine, control system, and method of operating a wind turbine (1) under potential icing conditions to reduce vibrations during idling or standstill operation, comprising: determining a potential icing condition for one or more blades (2,3,4), establishing a danger zone (10) where the falling of ice is to be avoided, identifying a risk of falling ice within the danger zone (10, wherein if a risk of falling ice in the danger zone (10) is identified, the method comprises: a) setting a pitch angle (P) of a first rotor blade (2) close to 0°, wherein a one or more further blades (3,4) comprise a pitch angle (P) differing by at least 30° from the first rotor blade (2); and b) adjusting the rotor yaw orientation (W) away from the danger zone (10).
