Abstract

Wind power is non-pollution energy. Wind energy is getting more attentions when the energy problems come out. Blades are the most critical parts in the wind turbine, so it's very important to do research on the wind turbine blades. In this paper, 300W small wind turbine blades are used for test analysis. The test is based on structural analysis of the blades and layout of the Bragg sensor (FBG) and strain gauges. The smart blade static load experiments were done on a single point and multiple points load. The FBG sensors strain monitoring results shows the same strain distribution rule as finite element simulation result, which confirmed that wind turbine blade structural health monitoring using FBG sensor is feasible.
