On the Aerodynamics of Wind Turbine
2003 International Joint Power Generation Conference, 2003The history and background of modern wind turbine technology were reviewed. The most widely used wind turbine airfoil shapes were presented. The previous studies on rotor-wind interaction emphasizing on the velocity deficit of the wake region of the wind turbine, the aerodynamics and structural dynamics of wind turbine airfoil were presented and ...

Publisher Summary The chapter elaborates the design of the modern wind turbine based upon aerodynamic principles. Wind power comes from the conversion of wind energy into electricity using wind turbines to drive the electrical generators. Wind turbines fall into two main categories—those that depend upon aerodynamic drag to drive them and those that ...

A Dynamic Wind Turbine Simulator of the Wind Turbine Generator System [PDF]
2012 Second International Conference on Intelligent System Design and Engineering Application, 2012 To study dynamic performances of wind turbine generator system (WTGS), and to determine the control structures in laboratory. The dynamic torque generated by wind turbine (WT) must be simulated. In there paper, a dynamic wind turbine emulator (WTE) is designed, which consider wind shear and tower shadow effect, and a dynamic torque compensation scheme ...

By now, utilising wind energy to generate power has become widely accepted as being necessary for ecological reasons, especially with a view to climate change but also to the preservation of fossil energy resources. Regardless of this fact, the question of costs must be put and answered.

The recently released revision of the international safety standard for small wind turbines defines a small wind turbine as having a rotor swept area (equal to πR 2 where R is the radius of the blade tip) of less than 200 m2. This corresponds to R < 8 m and a rated power below about 50 kW.

33rd Wind Energy Symposium, 2015
This paper presents a power control algorithm that aims at keeping a wind turbine within its safe loading envelope at all times. An online optimization procedure is used to find those wind speed variations that would lead the wind turbine response to approach the border of the safe operating region, without crossing it.
