How does wind power work? If it is needed to explain simply, a wind turbine takes over the rotor from the wind blowing the energy.
The wind turns the rotor in rotation – the “rotational energy” is then converted into electricity with the help of a generator, similar to a bicycle dynamo.
From there, the electrical energy goes into the power grid. The height of the system is very important. The larger the plant, the more uniform the wind blows and the more electricity can be generated. Today on freelectricity.net, we will review the how does wind power work matter.
How does wind power work? Detailed information
Larger plants – more efficient wind yield
In the lower, near-ground layers, the air is very turbulent, also because of the many obstacles (houses, trees, …). Therefore you build wind turbines as high as possible, because further up the wind blows constantly and evenly.
With each meter a windmill is built higher, the power output increases by 1%. With a doubling of the wing length, the yield increases fourfold. The double wind speed produces eight times the yield.
Although wind turbines are high-tech products, today’s production and construction is possible in a very short time – with low energy consumption. Thus, the energy necessary for the production and construction of a plant is generated by the windmill itself within 4-6 months. How does wind power work? Details below.
How does wind power work? Advices and tips
Wind turbine types
Basically, today two different types of wind turbine have prevailed. Similar to the cars, where the technology of the diesel and the Bezin engine co-exist, there are also two different technical approaches to the wind turbines.
Gearless system
Here the generator sits right on the rotor. It turns as fast as the rotor and therefore has to be very large. Similar to a bicycle dynamo, it generates electric current from the rotary motion.
Plant with gear
In a gearbox with gearbox sits between the rotor and the generator, the transmission. This makes the generator smaller and rotates faster than the rotor – up to 100 times faster.
