Optimization of Wind Turbine Blades

Abstract

WT blade manufacturing cost of approximately 15 to 20% of the production cost of wind turbines. Expenses innovations in the design of the blades represent a small amount of the total cost of production of the wind turbines. The benefits from the best structural model, and the use of suitable fusing materials and better manufacturing techniques, both sheets and composite materials, necessitating the application of numerical modeling and optimization techniques. In the design of a wind turbine, the goal is to achieve greater output power possible under specific climatic conditions. Technically, this depends on the shape of the sheet. Changing the blade shape is one of the ways to adjust stiffness and stability, but can affect the aerodynamic efficiency of the wind turbine. Another way of changing the dynamic mechanical properties of the wind turbine is modified composite material, which is made from the blade. Problem determining the optimal shape of the blade and the determination of the optimum composite is a complex subject, since the mathematical description of the aerodynamic and complex load, and a number of limitations and objectives must be satisfied. These considerations have led the authors to address the problem from various optimum design of wind turbine blade standards. The objective of this study is to develop a software package that allows the optimization of wind turbine blades in a series of criteria
