Wind turbine with damping

Wind turbines are provided comprising a support structure having a tower and a nacelle mounted on the support structure. A first region (damper region) of the wind turbine including at least a first part of the nacelle is flexibly coupled to a second region (to be damped) of the wind turbine includi...

Zusammenfassung:	Wind turbines are provided comprising a support structure having a tower and a nacelle mounted on the support structure. A first region (damper region) of the wind turbine including at least a first part of the nacelle is flexibly coupled to a second region (to be damped) of the wind turbine including at least the support structure. Methods are also provided for determining a suitable stiffness of the flexible coupling of the damper region to the region to be damped of any one of said wind turbines. These methods comprise determining a modal mass of the region to be damped depending on a given tower bending mode; and determining the stiffness of the flexible coupling of the damper region to the region to be damped depending on the calculated modal mass of the region to be damped and on the mass of the damper region.
