Location Determination of Impact on the Wind Turbine Blade Surface Based on the FBG and the Time Difference

This paper proposes an approach to the determination of the precise location of an impact on the surface of a wind turbine blade (WTB) based on a fiber Bragg grating (FBG) and the time difference, and its effectiveness is verified by experiments. First, the strain on the WTB surface is detected with...
