Modern wind turbine blades become more and more flexible with its increasing size. Under extreme wind excitations, the considerable blade deformation may result in large deflection at blade tip. This paper proposes a Variable Step Deformation Difference Method (VSDDM) to analyze the nonlinear blade structure. The VSDDM has the advantages of distinct concept, easy to understand, and simple to program. Owing to the linear solution always bigger than the nonlinear solution, the design would be conservative based on the linear solution.
