Now that you have a good understanding of the components of a wind turbine, let’s take a look at how the wind turbine operates and generates electricity. The process of generating electricity is:
(1) This process is initiated by the turbine blade/rotor. As the wind blows, the aerodynamically designed blades start to rotate by the wind.
(2) When the blades of the wind turbine rotate, the kinetic energy of the movement is transferred to the inside of the turbine by means of a low-speed shaft, which will rotate at a speed of approximately 30 to 60 rpm.
(3) The low-speed shaft is connected to the gearbox. The gearbox is a transmission device responsible for increasing the speed from about 30 to 60 revolutions per minute to reach the rotation speed required by the generator (usually between 1,000 and 1,800 revolutions per minute) .
(4) The high-speed shaft transfers the kinetic energy from the gearbox to the generator, and then the generator starts to rotate to generate electrical energy.
(5) Finally, the electricity it generates will be fed down from the turbine tower via high-voltage cables, and will usually be fed to the grid or used as a local power source.
