Abstract. Wind turbines are complex nonlinear machines whose main objective is to convert the wind energy into electric power. These systems work in two main operating regions. In region 2, the energy captured must be ...

In this paper we investigate the sources of cyclic loads affecting the structural solicitation and power production in Horizontal Axis Wind Turbines, in particular the role of blade-section misalignment. These loads could ...

In this work, we present an aeroelastic model intended for three-blade large-scale horizontal-axis wind turbines. This model results from the coupling of an existing aerodynamic model and a structural model based on a ...

The lodgment of wind sites is in a visible growing demand not only in Brazil, but all over the world. The wind energy, even though consolidated, still hosts many scientific researches and industrial development in several ...

The energy production coming from renewable sources is growing in the world energy matrix. This is due to the investment in research and technology improvement. In the renewable energy scenario, wind energy is distinguished ...

The main problem of a wind turbine generator design project is the design of the right blades capable of satisfying the specific energy requirement of an electric system with optimum performance. Once the blade has been ...

The consumption of electric energy is increasing. This growth stimulates production that is entirely based on fossil fuels. However, for social, political or environmental reasons there is a need to change the energy source. ...
