Method of evaluating quality of wind turbine blade
25 Oct 22
A method of evaluating quality of a wind turbine blade which has a hollow structure where an interior space of the wind turbine blade is surrounded by an outer skin which includes a laminated body includes: setting a scanning line on at least a part of an inner wall surface or an outer wall surface of the outer skin; and moving an ultrasound probe along the scanning line; generating a cross-sectional image corresponding to the scanning line, on the basis of a position of the ultrasound probe or a reflection echo to detect an indication whose echo level is greater than a first threshold; obtaining an inclination of the indication with respect to a reference line as a first parameter; and evaluating the lifetime or the breakage risk of the wind turbine blade on the basis of the first parameter.
