Abstract
A method of determining a frequency of an oscillating movement of a wind turbine tower. The wind turbine tower includes a nacelle and a generator including a stator and a rotor, the oscillating movement causing a rolling movement of the nacelle, the method including obtaining a first signal indicative of rotor speed relative to the nacelle, obtaining a second signal indicative of rotor speed relative to ground, determining a first amplitude spectrum based on the first signal, determining a second amplitude spectrum based on the second signal, determining a difference function based on the first amplitude spectrum and the second amplitude spectrum, and determining the frequency of the oscillating movement of the wind turbine tower as a frequency corresponding to a peak in the difference function. A device for determining a frequency of an oscillating movement.
