How to transform wind energy into electrical power
Wind energy is the result of converting the kinetic energy of wind into other forms of energy such as electricity and mechanics. In our day, wind energy is mainly converted into electricity through a wind farm.Wind power was the primary source of renewable energy to be discovered and used by man, after the fire. An early form of the conversion of kinetic energy of the wind there was the windmill was invented in the seventh century AD Seistan about the region, in today’s Afghanistan. The use of the windmill as a driving force to grind the grain, to pump water from the Dutch polders and irrigation, was abandoned during the nineteenth century with the invention of steam engines powered by coal, much cheaper then. Since 1970 however, the growing demand for energy and rising raw material costs, has revived the interest in wind energy.The funds for research and development of wind energy, combined with increased environmental awareness, soon led the first results: the worldwide use of wind power has quadrupled from 2000 to 2006 and in 2008 it reached a record of more than 27,000 megawatts of new capacity installed around the world, for a total of over 120.ooo megawatts of wind power, corresponding to 1, 5% of global demand for energy. Wind energy also has another first: it is clean energy with the best cost/production ratio.The conversion of kinetic wind energy is essentially through two types of electric generators, a vertical and a horizontal axis. The first, Vertical Axis Wind Turbines (VAWT), is characterized by a few moving parts in its structure, something that gives the generator a high resistance to gusts of wind that can come from any direction to take. A single turbine VAWT is able to meet the energy needs of 1,000 homes. Issues related to the limited size of the rotors 100 meters in diameter and height of towers that cannot exceed 180 meters, and it is known that the wind speed increases with distance from the ground, have led to the replacement of the turbines with vertical the most favorable wind turbines. Are currently in a single industrial installation with a vertical axis, the wind farm at Altamont Pass, California, now being dismantled. The horizontal axis wind turbine (HAWT, Horizontal Axis Wind Turbines) is composed of a steel tower and a rotor with 2 or 3 blades, capable of producing a quantity of energy varies widely, including in the 600 kW, the demand for about 1,000 homes. The operation of wind turbines requires a minimum wind speed of 3-4 m / s and each generator can produce up to 1.5 MW of clean energy. The new frontier in wind energy from wind is offshore, systems installed a few miles from the coast to take advantage of the strong currents in these areas. Today, the only European plants provide more than 100 thousand megawatts of wind energy.
Wind Energy -Have you ever noticed of a homemade wind generator? Yes, you noticed me proper. What I mentioned was no mistake, I was referring to a do it your self (Diy) wind generator. Believe about it, with the growing requirements for fossil fuels the supply of which continues to decline rapidly. And consequently, due to that reason, we must not be surprised when the prize for vitality, more particularly electrical power, also goes up.But just before we go to the procedure in creating your homemade wind generator, let us very first answer the question “what is a wind generator?” As the name recommend, wind generators are products that can produce electrical energy with the use of wind vitality and some other supporting components or products. One particular of the crucial elements essential in wind generators are the electrical power generator. In the exact same element, these are devices that convert the mechanical vitality into electrical power. To make it clear, wind energy is very first utilized to develop mechanical power and that made electricity is employed to create electricity. Moreover, wind generators can appear in a good deal of various shapes and sizes.The very first step that needs to be taken in the path to cash saving is to very first have a small workspace or perform bench. Your front porch or garage can be utilized, all you will need is a table, chair and the necessary equipment and components. And the supplies and resources shall be determined by your homemade wind generator pattern or plans. Your design and strategy will depend on plenty of aspects, but the primary aspect ought to be how much electrical energy do you desire to produce? Additionally, you can do a short and fast on the web analysis on wind generators to have a fundamental understanding of the functioning and requirements of such.Selecting just the right, superior and necessary supplies are the soul of your Do it yourself wind generator project. On this note, some of the fundamental necessities will absolutely consist of a generator, a set of batteries, blade hub, rotor, which is also identified as the blades, the tower or entire body, mounting, the tail, wire, and screws. In addition, you will also need the electrical pliers, saws, and wrenches.A single of the things that you will have to have to start off on first is the blade of the Do it yourself wind generator. The blades can be made from a carbon fiber, PVC pipe, wood or even other resources. Your layout for the blades shall be dependent on the preferred electrical power generation, your motor type and on the uncontrollable wind velocity of the region.After producing the blade, you can setup your DC or wind generator. The hub must all be tested if they fit effectively. It is as straightforward as the hubs of a laptop or computer. As for the system, steel tubing is an excellent option for material. The tail can be produced from employed resources, the tail is crucial since it shall be responsible for the balancing and be directing of the windmill. The generator tower is comparable to the television tower lines, or any poles can do as long as it has a robust and sturdy property.And once all the elements of your Do-it-yourself wind generator are ready, you can assemble it simply. Now you will connect the motor to the hub. Attach and tighten the blades upon installation. Your wind generator can be connected directly to an electric grid of a chosen property appliance. The evening light bulb can be an example. Or if you hope to save the electricity, you can use batteries.Moreover, be sensitive to the conditions outside. Don’t forget that wind generators are useless without a blowing wind. As a rule of thumb, the height of the unit must be at least 30 feet greater than any other obstructing buildings, and at least inside of 400 feet diameter of the tower. And lastly, your homemade wind generator ought to be capable to survive a really robust wind or weather conditions.Follow Us
