摘要： A load monitoring system for wind turbine blades utilises 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 maximise 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.

摘要： A device for detecting lightning currents in a wind turbine comprises an inductive loop (1) for carrying a current representative of a lightning current and a sensitive element, such as a resistance or a piezoelectric element electrically connected to the inductive loop (1). The apparatus further comprises an optical fibre strain sensor mechanically connected to the sensitive element, such that, in use, a lightning current results in expansion of the sensitive element and the optical fibre strain sensor produces an optical signal indicative of the strain on the sensitive element due to the expansion. The device has the advantage that the optical signal from the optical fibre strain sensor can be processed by the same signal processing equipment that processes signals from other strain sensors provided on the wind turbine.
