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.

Abstract: The invention comprises a turbulence sensor and sensor system for determining the condition of a wind turbine blade. A turbulence sensor comprises a sensor membrane provided in the surface of a wind turbine blade. A light source and light detector provided in a sensor cavity in the blade illuminate the sensor membrane and detect the light reflected back. The reflected light is mixed with non-reflected light to give an interference pattern indicative of the quality of the airflow, whether it is laminar or turbulent. The turbulence sensor can be used in a sensor system for detecting the accumulation of unwanted matter, such as dirt or ice, on the blade.
