The diagram illustrates how electricity is generated using a wind turbine.
Overall, the diagram shows the mechanism of a wind turbine, involving several main stages that work together to generate electricity. The process begins with wind turning the turbine blades and ends with the electricity being supplied to homes through a substation.
Looking first at, wind causes the blades of the turbine to rotate. That movement turns the rotor, which is connected to a drive shaft inside the turbine. This rotating motion then is transferred through the drive shaft to a gearbox where the rotational speed is increased before passing the generator to create electricity. In addition, the wind monitor measures both speed and direction of the wind, while a rotating motor automatically turns the turbine so that the blades always face the wind directly, allowing the turbine to function more efficiently.
Turning to the final stage of the process, the generator receives the energy and converts it into electricity. Meanwhile, the wind that passed through the turbine continues to move away, but it has reduced speed and energy after driving the blades. The electricity is then carried away from the turbine through underground cables. These cables transport the electricity to a substation, where it is processed and prepared for distribution. Finally the electricity is supplied to homes for domestic use.
