Four major systems of wind turbines

The main components of a wind turbine include the rotor, generator, tower, nacelle, and control system. What is the function of the rotor in a wind turbine? The rotor, also known as the blades or propellers, captures the kinetic energy of the wind and converts it into rotational motion. What does the generator do in a wind turbine?

A wind turbine has four major sections—the tower, hub, blades, and the machine head, or nacelle (see Figure 1). Figure 1 Each of the four major wind turbine sections—tower, hub, blades, and nacelle—must withstand tremendous temperature and wind conditions. During operation, blades tip speeds commonly exceed 160 miles per hour.

The most important component of WECS is wind turbine. This was synonym to the earlier term wind mill. Wind turbine system is essential to harness the wind energy exists in any location. The main components of a wind energy conversion system for electricity (Fig 1) are Aeroturbine Gearing Coupling Electrical generator Controller

The control systems of the wind turbine monitor and regulate the operation of the machine, adjusting the blade pitch and yaw to optimise energy capture under different wind conditions. The rotor blades are the most visible parts of a wind turbine. Their primary role is to capture the kinetic energy of the wind and convert it into rotational energy.

Utility-grade turbines can be constructed of as many as 22 major component groups and 8,000 subcomponents, creating a multitude of manufacturing opportunities. Here, ironworker John Hammack installs components for Blattner Energy on a NextEra Energy wind turbine.

3.3 Blades: This is a rotating component of the system. This component is based on the principle of lift and drag (principle of aerodynamics). It converts kinetic energy first to mechanical energy and then transferred through shaft to generator for converting into electrical energy. Two or three blades are common in the wind turbines.
