Abstract
The invention provides for a wind turbine comprising a rotor comprising at least one rotor blade, a yaw controlling system including yaw control means, a yaw mechanism comprising one or more yaw motors and a yaw bearing, registration means for registering an idling power producing situation of the wind turbine in relation to a utility grid, and detection means for detecting edgewise oscillations in one or more of the blades. The yaw controlling system is adapted for changing the yaw position of the wind turbine nacelle when said registration means registers that said wind turbine is operating in an idling power producing situation and the detection means detects edgewise oscillations in one or more of the rotor blades, hereby damping or eliminating the edgewise oscillations. The invention further relates to a method for controlling a wind turbine and use hereof.
