Abstract
A detuner system for a wind turbine includes a drive train component having a natural frequency. The drive train component is configured to rotate about an axis of rotation at a range of different speeds. The detuner system includes a controller for selectively interacting with the drive train component and cause a step change in the natural frequency of the drive train component at a first threshold of the rotational speed range, and cause a step change in the natural frequency of the drive train component at a second threshold of the rotational speed range different to the first threshold.
