Abstract: As an clean renewable energy source wind energy is highly regarded by various countries in the world. Wind turbine blade is one of the most important components in wind turbine. It is the key component for receiving wind energy. As turbine size steps up and the size of modern turbine blade increases, condition monitoring and maintenance of blades become more important. Strain detection is one of the most effective methods to monitor blade condition. Sensitivity for EMC and lightning and zero drift of conventional strain gauges bring a lot of trouble. In this paper, a fibre Bragg grating sensor system is used for blade monitoring. The system overcomes the shortcomings. It is dainty, reliable, convenient to multiplex and so on.
