Fiber Bragg grating sensor system for operational load monitoring of wind turbine blades

A fiber optic Bragg grating sensor system has been installed in the blades of a wind turbine and was successfully tested for several years. We report the requirements, system design and construction parameters of a sensor system for continuous on-line monitoring of bending loads of the rotor blades, and provide characteristic examples of monitoring results.
