<P>PROBLEM TO BE SOLVED: To provide a wind turbine capable of exhibiting large vibration damping effect in a wide frequency band specific to the wind turbine. <P>SOLUTION: The wind turbine has a TMD (tuned mass damper) adjusted to damp vibration in a specific frequency of the wind turbine and an AVC (active vibration control) adjusted to damp fluctuational frequency of a turbulence of wind flowing into the wind turbine and/or the vibration in the frequency of the rotational frequency wind turbine blades, and a pitch angle control section having a correct section for adjusting the vibration damping frequency of the AVC. The AVC is configured to obtain vibration damping force by changing the pitch angle of the wind turbine blades. <P>COPYRIGHT: (C)2012,JPO&INPIT |
