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.
