Abstract
A wind turbine includes a first vibration sensor for producing a first vibration signal; a second vibration sensor, displaced from the first vibration sensor, for producing a second vibration signal; and a processor for comparing the first vibration signal to the second vibration signal and controlling the wind turbine in response to the comparison.
Claims16
A wind turbine, comprising:
- a first vibration sensor for producing a first vibration signal;
- a second vibration sensor, displaced from the first vibration sensor, for producing a second vibration signal;
- and
- a processor for comparing the first vibration signal to the second vibration signal and controlling the wind turbine in response to the comparison.

A wind turbine, comprising:
- a tower;
- a frame supported by the tower;
- a first vibration sensor, arranged on the tower, for producing a first vibration signal;
- a second vibration sensor, arranged on the frame, for producing a second vibration signal;
- and
- a processor for subtracting the first vibration signal from the second vibration signal to create a differential vibration signal, and for controlling the wind turbine in response to the differential vibration signal.
