AB  - The wind turbine blade is the system that changes kinetic energy of the wind into the mechanical
energy, it is categorized into the main component, since, it can have an impact on power performance of wind
power generation system, energy conversion efficiency and load and dynamic stability. Therefore, it requires
the integrated design of aerodynamic-structure and the structural integrity has to be validated through design
evaluation by international standard or certification agency in order to achieve optimum design of blade. In
this study, the detailed explanation on evaluation category and criteria required for certification of blade design
as well as the result of structural integrity of which compatible to multi-MW blades are presented. The
calculation results of the ultimate strength by finite element analysis, the energy release rate was reviewed and
it was confirmed that the wind turbine blade meets the structural integrity in the part of strength.
