Abstract
A wind turbine is provided, including a hub, rotor blades, wherein each rotor blade is rotatably supported at or in the hub by a pitch bearing, a pitch control device for changing a pitch angle of the rotor blades, and a measurement system for capturing a sensor signal in or at the pitch bearing and for changing the pitch angle by the pitch control device as a function of the sensor signal to prevent failure of the pitch bearing due to a lack of lubrication, wherein the sensor signal represents a change in vibration, noise and/or temperature in or at the pitch bearing. Due to the fact that the pitch angle can be changed as a function of the sensor signal, lubrication of the pitch bearing is ensured throughout the lifetime of the pitch bearing. Unnecessary pitch movements can be prevented.
