1.2 MW wind turbine blade aerodynamic and material optimisation with finite element method

In order to further increase the use of wind turbines, the benefit / cost ratio needs to be raised, which is the cost of energy referred to as TL / kWh for wind turbines. The cost of energy is the ratio of the amount of electricity produced by the wind turbine to the cost of producing the wind turbine. Increasing this value will cause the use of the wind turbine to increase further. Material and installation costs, which are directly related to the weight of the blade, constitute a significant part of the cost of the turbine. Designing a wind turbine optimized for aerodynamic optimization in accordance with the wind conditions of our country will enable this wind turbine to produce more energy than other imported turbines under the same wind conditions. Under these operating conditions, the wind turbine, which is said to have similar strength, is optimized for the material to be lighter than its blades and reducing the weight will reduce the energy cost and increase the utilization rate. This project, compared to similar scale imported wind turbines, is intended to design prototype manufacturing the blade of the 1.2 MW horizontal axis wind turbine, which will produce more energy with aerodynamic optimization, and will be lighter than similar-sized wind turbines due to optimizing weight of turbine . Imported wind turbines of similar size are designed on the basis of the wind conditions in the countries where they are produced so that our country is able to produce energy even at low wind speeds on the basis of the wind conditions in our blade country. As a result of the project, the blade of the wind turbine, which will have high energy efficiency in the wind conditions in our country, is designed. At the same time, the wind turbine blade, which is having no problem about strength similar power wind turbines and lighter than the others, was obtained.
