The plant (10) has a rotor (18) that is driveable by wind, where the rotor is provided with a rotor blade (22). A generator converts the mechanical energy of the rotor into electrical power. The rotor is arranged at a tower (14), and the rotor blade comprises a set of additional masses, and active and/or passive vibration absorbers. The additional masses are arranged for changing natural frequency of vibration of the rotor. An independent claim is also included for a method for operating a wind power plant. |
