1. A system for a wind turbine, comprising:
a detuner system;
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 via the detuner system,
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 via the detuner system, and to cause a step change in the natural frequency of the drive train component below a second threshold of the rotational speed range via the detuner system,
wherein the rotational speed at the second threshold is different to the rotational speed at the first threshold.
