| 摘要 |
The invention relates to a method for operating a wind energy installation (10) with a rotor (12) and at least one rotor blade (14), which can be adjusted in terms of its angle of attack. The invention is characterized by the fact that the rotor blade (14) is accelerated by virtue of at least five repeated adjustment operations of the angle of attack about its longitudinal axis (15), wherein a rotor-blade bending vibration with a vibration amplitude and a vibration frequency is excited. |
