Research on damage detection of wind turbine tower based on OFDR

Abstract

A wind turbine tower damage detection method based on optical frequency domain reflection (OFDR) technology is proposed in this paper, which can detect structural damage position and damage degree of wind turbine towers. The damage location of the wind turbine tower structure can be accurately detected by the method with a spatial resolution of 1cm, the detection error of damage degree is less than 2.2%. This method provides a candidate solution for real-time detection of wind turbine tower damage.
