Abstract: A system and method for the verification and calibration of wind turbine sensor systems is provided. The system comprises an optical capture device provided on a wind turbine which is arranged to record the position of at least one light source provided at the wind turbine during operation of the wind turbine. The motion of the light source relative to the optical capture device can provide an indication of relative motion of a portion of the wind turbine during operation, which can then be used as an input to a calibration and/or a verification system for a sensor system of the wind turbine.

Abstract: A manufacturing method is described for a wind turbine blade, where layers of fibre material are laid up in a mould to form a portion of the blade structure. The fibre layers are infused with a resin which is subsequently cured to form the hardened blade structure. Some of the layers of fibre material are arranged so that a portion of the layers are kept resin-free during the infusion and curing steps, so that the fibre layer extends freely out from the external surface of the blade, preferably at the blade trailing edge, to provide a flexible blade trailing edge to reduce blade operational noise.

Abstract: A method for the calculation of a wind turbine blade deflection is described. The method utilises a known blade modal profile in the calculation of the blade deflection, such that the a priori knowledge of the blade excitation modes can be used with a simple distance measurement to determine the blade deflection shape. The calculated blade deflection can then be used as an input to control wind turbine operation, e.g. where it is likely that the deflected blade might result in a tower strike.
