    摘要： The object of the invention is to provide lighting for the rotor blade tips, which is more reliable than that proposed hitherto, wherein any damage which occurs is no longer so complicated and expensive to rectify as hitherto, but can be rectified extremely swiftly. A rotor blade of a wind power installation with a rotor blade connection to a hub of the wind power installation and a rotor blade tip at the end of the rotor blade, which is in opposite relationship to the rotor blade connection, characterized in that at least one light waveguide is laid from the rotor blade connection to the rotor blade tip. The light can be modified to be on only when the blade is at the top portion of the rotation, such as between the 9:00 and 3:00 positions, or the 10:00 and 2:00 positions.

    摘要： A method for detecting ice on a wind turbine having a rotor and one or more rotor blades each having blade roots includes monitoring meteorological conditions relating to icing conditions and monitoring one or more physical characteristics of the wind turbine in operation that vary in accordance with at least one of the mass of the one or more rotor blades or a mass imbalance between the rotor blades. The method also includes using the one or more monitored physical characteristics to determine whether a blade mass anomaly exists, determining whether the monitored meteorological conditions are consistent with blade icing; and signaling an icing-related blade mass anomaly when a blade mass anomaly is determined to exist and the monitored meteorological conditions are determined to be consistent with icing.

    摘要： 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.
