The great wind turbine
The truth is that wind power would have no reason to be if it weren't for himwind turbine, the modern windmills that cut through many fields and territories. The one we see in the video is a model with wind turbine one of the largest in existence, manufactured by the German company Enercon.
With a hub height of 135 meters, rotor diameter of 126 m and a total height of 198 m, this model can generate up to 7.58 Megawatts of power per turbine. The price of a unit of these characteristics amounts to 14 million dollars.
But… What is a wind turbine? How do wind turbines work? and What are the parts of a wind turbine?. These are questions that in part, through the following infographic, we can test a better understanding of the characteristics of windmills modern:
Wind power has its advantages and disadvantages, actually like any energy production system. Actually, the operation is easy and its fundamentals are seen with the naked eye. The action of the wind moves the Pallas of the wind turbine and these make the rotor. As easy as that. The "windmills" they are actually a true work of engineering that day after day they are more familiar to us in the landscapes of any country generating electric power at the mercy of the action of wind.
The perceptible parts of a wind turbine are the nacelle, which is the casing that protects its internal mechanism) and the rotor blades which can be up to twenty meters long, apart from the tower that maintains it.
If we look inside, we will find a piece called bushing that joins the blades with a low speed shaft whose movement does not exceed thirty rpm and is connected to a multiplier. Although we see that mill blades they do not move at a high speed, when passing through the multiplier, they accelerate significantly increasing the speed.
If the wind changes direction … Are we going to lose energy? No, because for that there is another component, the electronic supervisor, which controls the wind conditions and reorients the blades as necessary to adjust and not lose the opportunity to generate electricity.
Recall that in the article on the future of wind energy we already saw that within the renewable It is on the rise and by this year 2016 offshore wind energy will double in Europe. The big energy companies are not missing the opportunity to take advantage of the wind.
