    摘要: The invention relates to a method for damping tower oscillations in the tower of an active stall controlled wind turbine. The method comprises the steps of operating two or more blades of the wind turbine in a stall condition, detecting if the tower oscillates beyond a predefined level, and establishing different stall conditions between at least two of the blades, wherein the different stall conditions are established by offsetting the pitch angle of at least a first blade in relation to the pitch angle of one further blade. The invention further relates to an active stall controlled wind turbine and use hereof.

    摘要: The invention relates to a wind turbine comprising a rotor including one or more pitchable blades, and detection means for detecting edgewise oscillations in one or more of said blades. The wind turbine is characterized in that the wind turbine comprises control means for changing the pitch angle of one or more of the blades if the detection means detects edgewise oscillations in one or more of the blades, hereby damping or eliminating the edgewise oscillations. The invention further relates to a method for damping edgewise oscillations in one or more blades of a wind turbine and use hereof.
