Abstract

A fiber grating sensor system for use in condition monitoring of wind turbine blades is constructed. A rotary optical joint was used to connect the fiber grating sensors to the non-rotating signal processing unit with moderate insertion loss. The Bragg wavelengths were interrogated by a spectrometer demodulator which consisted of a volume phase grating and a 512-pixel photo-detector array. Using the constructed sensor system, various strain/temperature measuring experiments have been performed. We applied fiber grating sensors at different locations on the wind turbine blade. Different types of strain, stroke, and temperature variations were applied to the sensors and the results were analyzed according to the sensor locations and the blade's rotary speed.
