CA 2566376
The invention relates to a wind energy installation (10) having a rotor (18) which can be driven by wind and has at least one rotor blade (22), having a generator for conversion of the mechanical energy of the rotor (18) to electrical energy, and having a tower (14) on which the rotor (18) is arranged, in which the rotor blade (22) has one or more additional masses (36, 40) and/or active and/or passive oscillation dampers (24), which are designed in such a manner that movements of the rotor blade (22), in particular oscillations, which are initiated by external influences and are directed towards the tower or away from it are prevented and/or damped. The invention also relates to a method for operation of a wind energy installation, preferably of an off-shore wind energy installation, in which one or more components of the wind energy installation, preferably the tower (14), have opposing vibration applied to them in order to reduce/prevent sound waves which result from component vibration and disturb animals and/or people, which opposing vibration counteracts vibration (which produces sound) of the component (14), and reduces or prevents this component vibration.
