Abstract: A method for monitoring a wind turbine comprises monitoring an acoustic signal and/or a vibrational signal within a tower of the wind turbine, analysing the signal to identify one or more predetermined characteristic indicative of an event within the tower, recognising the event has occurred based on the predetermined characteristic and generating an output based on the recognised event. The one or more predetermined characteristic being at least one of: an amplitude of the signal, a duration of the signal, a shape of the signal, one or more frequencies present in the signal and an energy of the signal.

Abstract: A yaw sensor for a wind turbine is described. The yaw sensor comprises a plurality of rotary switches, each configured to be coupled to a yaw drive gearbox of a wind turbine nacelle, the rotary switches each being operable to activate and deactivate respective associated electrical contacts in dependence on an amount of yaw rotation of the nacelle relative to a start position. Each electrical contact is active at a plurality of first yaw rotation ranges with respect to the start position, and inactive at a plurality of second yaw rotation ranges with respect to the start position, the first and second yaw rotation ranges being interleaved. The first yaw rotation ranges of the electrical contacts do not overlap each other between the start position and a first rotational position in a first rotational direction from the start position, and do not overlap each other between the start position and a second rotational position in a second rotational direction from the start position opposite to the first rotational direction. All of the electrical contacts are activated at the first rotational position and the second rotational position. The electrical contacts each generate a respective electrical signal when active. The activation of one or more of the electrical contacts between the first and second rotational positions confirms that the rotary switches are operating correctly, reducing the requirement for regular safety checks, and permitting yaw sensor supervision to be conducted by comparing pulses generated by the electrical contacts with the output of an angular encoder.

Abstract: A sensor system for measuring an operating parameter of a wind turbine component is described. The fibre optic sensor system comprises a light source for outputting light in a predetermined range of wavelengths, and an optical fibre comprising a long Fibre Bragg Grating, extending continuously over a length of the optical fibre to provide a continuous measurement region in the optical fibre. The optical fibre is coupled to the wind turbine component such that the continuous measurement region is located at a region of the wind turbine component to be sensed, and such that the grating period at each location in the continuous measurement period is dependent upon the value of the operating parameter at that location. The system further comprises a light detector for receiving light from the optical fibre, and for providing an output signal to the controller indicating the intensity of the received light; and a controller coupled to the light detector for determining, based on the detected light, a value for the operating parameter. In a particular embodiment the system is used to monitor the generator in the wind turbine nacelle. The optical fibre with the long FBG grating can the be inserted into the coil windings or stator slot of the generator.

Abstract: A system for identifying the likelihood of a wind turbine rotor blade striking a wind turbine tower comprises a device for sensing bending of a wind turbine rotor blade and a device for sensing bending of a wind turbine tower. In a preferred embodiment Long Period Grating (LPG) sensors are used to measure bending of the tower. Preferably a plurality of LPG sensors is provided along the length of the blade. In one embodiment at least one of the LPG sensors comprises two sensing elements arranged to sense in perpendicular directions. In another embodiment a plurality of LPG sensors are provided each on different sides of the wind turbine tower. A processor uses the sensed blade and tower bending to determine whether the distance between the blade and the tower will be below a predetermined minimum value. If the distance is determined to be below the predetermined minimum value a controller may be used to adjust a wind turbine variable to reduce loading on the blade and thereby reduce the likelihood of a tower strike.
