A Wind Turbine
Wind turbines are systems that first convert the kinetic energy in the current created by the winds into mechanical energy and then into electrical energy. Wind turbine structures generally consist of a tower, blades, rotor, gearbox, generator (alternator), and electrical-electronic elements. The moving kinetic energy of the wind is converted into electrical energy by a rotor mechanism. Two important aerodynamic forces must be well known to understand how wind turbines work. These are drag and lift forces.
History of Wind Turbines
For the first time in history, the wind wheel of Heron of Alexandria was recorded as the first wind turbine to move a machine. However, the first known practical wind farms were built in Sistan, an eastern province of Persia (now Iran) in the 7th century. These “Panemone windmills” were long vertical drive shafts with rectangular blades and vertical axis windmills. These windmills, made of six to twelve sails covered with reed wicker or cloth material, were used in milling and the sugar cane industry for grinding grain or drawing water.
Wind energy first appeared in Europe during the Middle Ages. The first historical records of their use in England date from the 11th or 12th centuries. There are records of German crusaders taking their windmill-building skills to Syria around 1190. Windmills, 14. In the 19th century, Dutch windmills were also used to drain water in the Rhine delta area. Advanced wind turbines that date back to the present were invented by Croatian inventor Fausto Veranzio. Veranzio, in his book Machinae Novae (1595), dealt with the vertical axis wind turbines with curved or V-shaped blades, which formed the basis of modern wind turbines.
How Much Energy Generate Wind Turbine Produce ?
A wind turbine is an energy generation system that is installed in places that receive a lot of wind. They can generate electricity when the wind speed is between 8 and 50 kilometers per hour.
Where they are usually installed, the wind speed is in this range 75 percent of the time. However, the wind does not blow at a constant speed under normal conditions. Therefore, the amount of energy produced by wind turbines can be very variable. However, according to the measurements, a single wind turbine produces the energy that can meet the electricity need of an average of 350 houses per year. The capacity of modern turbines is in the range of 660 kilowatts and 2.4, and they can produce energy at an average capacity of 30 percent.
As a result, an average wind turbine can produce enough energy to easily meet the annual electricity needs of approximately 350 houses.
