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.
