STRUCTURAL MONITORING IN WIND TURBINE BLADES |
摘要 |
A load monitoring system for wind turbine blades utilizes optical fibre strain sensors (5) moulded into the turbine blades. A sensor monitoring instrument is located in the hub (3) of the turbine. Various arrangements of cabling are disclosed to maximize fault tolerance. Various arrangements of a temperature compensation device for the strain sensors is also disclosed. The strain sensors (5) and optical fibre (7) may be provided on a pre-cured patch (9) for incorporation in the structure of the turbine blade. Furthermore, it is disclosed that each blade comprises an optical fibre strain sensor and a cable to connect the sensors to processing equipment, wherein each such cable includes a connector at each end whereby each blade can be replaced independently. Also, it is shown to provide an output connector for connecting the sensor to processing equipment in a cavity that is filled with a material for inhibiting free movement of the output connector. |
