Powers of Wind

Wind power technology
Wind is a clean source of energy that can be used endlessly. At present, the use of wind energy to generate electricity. Renewable production with energy from fossils. Especially in Europe, the development of wind turbine technology for electricity production commercially. Each large wind turbine can generate 4-5 megawatts of electricity, and more days will be developed to be larger and more efficient.

The development of wind power technology was fast, since in 1989 the size of the wind turbine at that time was 300 kilowatts with the diameter of the turbine blade 30 meters. After about ten years, there were manufacturers from many companies producing 1,500 kW wind turbine with diameter 70m turbine blade center and before the turn of the new century, a 2 MW wind turbine with a diameter of 74m. Was developed and installed for use. Today, 2 megawatts wind turbines have already become commercially produced. And 4 - 5 megawatts wind turbines are currently under development. The 4.5 megawatt prototype was installed and tested in 2002.

For the general principles of using wind energy are When the wind blows against the wind turbine blades The wind turbine transforms the wind energy in the form of kinetic energy into mechanical energy by rotating the blades. The force of the rotation of this impeller is transmitted through the spindle, causing the gears attached to the spindle to rotate accordingly. The mechanical energy obtained from the rotation of the gears is used in accordance with the requirements such as In the event that the wind turbine is to be used for electricity generation, the generator will be connected. When the gears of the wind turbine rotate, it will drive the spindle of the generator to rotate accordingly. With this principle, the generator is able to produce currents. Electricity can come out In the case of using wind turbines to pump water or rice, the mechanical energy from the rotation of this gear can be applied directly.

In terms of using energy from wind turbines Found that the country that has the most wind turbines today is Germany In 2001, Germany produced 8,754 megawatts of wind power, followed by the United States at 4,200 megawatts, Spain produced 3,300 megawatts, and Denmark produced 2,400 megawatts. Is the most advanced country in using wind power to generate electricity The total electricity production from wind energy is approximately 14,000 megawatts and the target is that by 2010, it will be able to generate 60,000 megawatts of wind power (Ledesma et al. 2003: 1341 -1355) and, looking back, in 1988, Germany produced only 137 megawatts of electricity from wind turbines. In those days there were still no more than a thousand wind turbines. But after fifteen years, Germany has installed more than ten thousand wind turbines and produced more than 8,000 megawatts of electricity. The area is not very far away, therefore it is a characteristic of a wind farm.

Sustainability
Current trends in sustainability (sustainable) and pollution-free technology Zero-emission technology is of interest to scientists, researchers or even politicians. The operation of the wind turbine does not cause pollution. It can be used as a technology to produce electricity instead of using energy from fossil fuels. And nuclear Therefore, wind turbine technology is another option for sustainable development.

In short, the wind is the movement of air. Due to the difference in temperature or air pressure between different sources on the earth, the wind will move from the cooler to the hotter. Or from areas with high air pressure to low pressure areas The movement of this wind Generating wind energy in the form of kinetic energy Because it is the movement of air mass that travels to the earth's surface horizontally in all directions at different speeds The application of wind energy through a tool called a wind turbine. Which can convert the kinetic energy from the movement of the wind into mechanical energy The mechanical energy obtained can be used directly or applied for electricity generation through a generator. Which will transform mechanical energy into electricity The use of wind turbines for electricity generation has been researching and developing wind turbine technology for over 100 years and is currently being used to replace the production of electricity from fossil energy at an increasing proportion. Because wind energy is clean energy, does not cause serious pollution. And is energy that has no cost in terms of sources
