Abstract
A method for operating a wind turbine, and the wind turbine comprises a generator for generating electrical power from wind, the generator having a generator axis, a nacelle for supporting the generator, and a tower for supporting the nacelle, the tower having a tower axis, and the method comprises the steps sensing at least one tower vibration by means of a vibration sensor, sensing a mechanical generator vibration, caused by at least one electrical fault, by means of the same vibration sensor, and controlling the wind turbine in dependence on the sensed tower vibration and the sensed generator vibration.

A method comprising:
- operating a wind turbine,
- sensing at least one tower vibration of the wind turbine by a vibration sensor,
- sensing a mechanical generator vibration, caused by at least one electrical fault, by the vibration sensor, and
- controlling the operation of the wind turbine in dependence on the sensed tower vibration and the sensed generator vibration, wherein the sensor is an acceleration sensor configured to sense vibration in at least two directions.
A wind turbine, comprising:
- a generator having a generator axis for generating electrical power from wind, wherein the generator is configured to be driven by an aerodynamic rotor having one or more rotor blades,
- a nacelle, the generator coupled to the nacelle,
- a tower for supporting the nacelle,
- a vibration sensor for sensing a tower vibration, wherein the vibration sensor is configured to sense a mechanical generator vibration caused by at least one electrical fault, and
- a controller configured to control the wind turbine in dependence on the sensed tower vibration and the sensed generator vibration, wherein the vibration sensor is an acceleration sensor configured to sense acceleration in at least two directions.
