摘要： A sensor system and method for a power electronics module is discussed. The system comprises a optical fibre 318 mounted inside the module housing 302 and connected to an external sensor system 320 (not shown). The optical fibre 318 is arranged so that it lies proximate to one or more semiconductor dies 308 within the housing, and can sense their temperature. The fibre can be connected to the die 308 by glue, mechanical connection, or can in other examples by provided in the underlying support structure such as a DCB (direct copper bonded ceramic structure) or base plate 304. The fibre can contain an optical grating, such as an FBG or LPG, or can operate based on interferometry, to detect temperature or strain.

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.

摘要： A sensor system for measuring an operating parameter of a wind turbine component is described. The fiber optic sensor system comprises a light source for outputting light in a predetermined range of wavelengths, and an optical fiber comprising a long Fiber Bragg Grating, extending continuously over a length of the optical fiber to provide a continuous measurement region in the optical fiber. The optical fiber 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. A light detector receives light from the optical fiber, and provides an output signal to the controller indicating the intensity of the received light; based on the detected light, a value for the operating parameter is determined.
