ABSTRACT:
The invention relates to a wind turbine comprising a rotor including one or more pitchable blades, registration means for registering an idling power producing situation of the wind turbine in relation to a utility grid, detection means for detecting edgewise oscillations in one or more of the blades, and control means for controlling the pitch angle of one or more of the blades. The control means is adapted for changing the pitch angle of one or more of the blades when the registration means registers that the wind turbine is operating in an idling power producing situation and 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 controlling a wind turbine and use hereof.
