    Abstract: A method for performing condition monitoring on a plurality of wind turbines of a wind farm comprises for each wind turbine, obtaining at least one vibration signal representing vibrations of one or more monitored components; generating a plurality of faulty frequency indexes on the basis of one or more of the obtained vibration signals, and in such a manner that variations in rotational speed of one or more rotating shafts of the wind turbine are filtered; comparing faulty frequency indexes originating from different wind turbines; and determining the condition of each of the monitored components based on the comparison.

    Abstract: The present invention relates to a method of controlling a wind turbine having at least one blade and a controller, including: detect location of foreign material adhered to the blade by sensors mounted on the blade and communicatively coupled to the controller; determine the resonance mode of the blade to be excited based on the location of the foreign material by the controller; and excite the blade to the resonance mode; wherein the resonance mode is one higher than the first order resonance mode. The present invention also relates to a wind turbine using the method.
