ABSTRACT:
A wind turbine comprising a wind turbine rotor with at least one wind turbine blade, a wind turbine tower, such as a standard tubular steel tower, positioned on a foundation and connected to the wind turbine rotor through a wind turbine nacelle, and a control for establishing oscillation control values of the wind turbine. The wind turbine being capable of altering the load for optimizing the tower eigenfrequency in response to acquired values from the controls. The invention also relates to a control system and method for altering the eigenfrequency of a tower of a wind turbine.
