How do wind turbines work?

Wind power is one of the most abundant cost-competitive energy resources.

Definition of A Wind Turbine

A wind turbine is a device that converts the wind's kinetic energy into electrical energy. Most wind turbines have three main parts: the tower, the blades and the nacelle.

Working of the Wind Turbine

  • After the wind approaches the turbine and its rotors spin around They turn the central drive shaft which is its supporter.

  • In modern turbines, the pitch control mechanism is observed. It is a methodology in which the rotor blades can swivel on the hub at the front.

  • The generator extracts the kinetic energy from the spinning drive shaft and converts it into electrical energy.

  • Anemometers and wind vanes provide some measurements of the wind speed and its direction.

  • Using these measurements, the entire top part of the turbine can be rotated and it even captures the maximum amount of energy.

  • A step-up transformer converts the electricity to a higher voltage.

Noteworthy Points on Wind Turbine

  • The power output from a wind turbine is directly proportional to the cube of wind speed.

  • Wind turbines operate over a wide range of wind speeds. If the wind is slow, they will not be able to turn at all and if too fast speed, they might even shut down.

  • Modern electric wind turbines come in a few different styles and sizes as per their usage, while the most common style being the "horizontal axis design”.

Wind energy is a very good option for renewable energy, especially when coal and other fuels cause a lot of pollution and are even exhaustible. Thus, these renewable sources of energy must be harnessed, as these are more profitable and less pollution causing.
