Wind turbine usually has six main components: the rotor, the gearbox, the generator, the control and protection system, the tower and the foundation. These main components can be seen in the figure below.
Rotor
The rotor takes the wind and aerodynamically converts its energy into mechanical energy through a connected shaft.
Gearbox
The gearbox increases the rotational velocity of the shaft for the generator. In some turbines, the gearbox is not needed because the rotational velocity or the torque from the shaft high enough.
Generator
The generator is a device that produces electricity when mechanical work is given to the system.
Control and Protection System
The protection system is like a safety feature that makes sure that the turbine will not be working under dangerous condition.
Tower
The tower is the main shaft that connects rotor to the foundation. It also raises the rotor high in the air where we can find stronger winds.
Foundation
The foundation or the base supports the entire wind turbine and make sure that it is well fixed onto the ground.
