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.
