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 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.

A detuner system for a wind turbine, comprising:
- a drive train component having a natural frequency and configured to rotate about an axis of rotation at a range of different speeds;
- and
- a controller for selectively interacting with the drive train component,
- wherein the controller is configured to cause a step change in the natural frequency of the drive train component above a first threshold of the rotational speed range, and to cause a step change in the natural frequency of the drive train component below a second threshold of the rotational speed range,
- wherein the rotational speed at the second threshold is different to the rotational speed at the first threshold.
A method of operating a wind turbine, the wind turbine comprising:
- a drive train component having a natural frequency and configured to rotate about an axis;
- and
- a controller for selectively interacting with the drive train component, the method comprising:
- rotating the drive train component about the axis at a range of different speeds;
- causing a step change in the natural frequency of the drive train component at a first threshold of the rotational speed range;
- causing 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.
