What Is a Wind Turbine?

Wind turbines are electrical equipment that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of wind turbines, generators (including devices), steering (tails), towers, speed-limiting safety mechanisms, and energy storage devices.

For many centuries, wind turbines, like hydraulic machinery, have replaced human and animal power as a source of power and played an important role in the development of productivity. The extensive application of modern electromechanical power and the discovery of oil fields in the Middle East in the 1950s

Research shows that the ways to improve the reliability of wind turbines include the following. ^[2]

In 2006, there were 6,469 wind turbines in China, of which megawatt-class units accounted for 21.2%. In 2007, this proportion jumped to 38.1%, an increase of 16.9 percentage points. In 2007, the cumulative installed capacity of global wind power reached 94,100 MW, an increase of 27% from the 74,200 MW of the previous year. In 2007, China's wind power installed capacity was 6.05 million kilowatts, and the planned target for 2010 was achieved 3 years in advance. In the 6 years from 2001 to 2007, China's wind power installed capacity increased 14 times; in 2007 alone, China's wind power installed capacity increased by 344.9 10 kilowatts, more than the cumulative total of Chinese wind power in history. With the rapid development of the wind power industry,

Usually people think that the power of wind power is completely determined by the power of wind turbines. I always want to buy a larger wind turbine, which is incorrect. The current wind turbines only charge the batteries, and the batteries store the electrical energy. People's final use of electric power is more closely related to the battery size. The size of the power depends more on the amount of air volume, not just the power of the nose. In the Mainland, small wind turbines are more suitable than large ones. Because it is more easily driven by a small amount of wind to generate electricity, a continuous small wind can provide greater energy than a temporary wind. When there is no wind, people can still use the electrical energy brought by the wind normally. That is to say, a 200W wind generator can also use a large battery and an inverter to obtain 500W or even 1000W or even greater power output. ^[5]

The use of wind turbines is to continuously convert wind energy into standard city electricity used by our homes. The degree of savings is obvious. A family's electricity consumption for a year only costs 20 yuan of battery fluid. However, the performance of wind turbines has been greatly improved compared with a few years ago. In the past, it was only used in a few remote areas. Wind turbines connected to a 15W light bulb directly used electricity, and the light bulb was often dark and often damaged. Now, due to technological progress, the use of advanced chargers and inverters, wind power generation has become a small system with a certain scientific and technological content, and can replace normal city power under certain conditions. Mountainous areas can use this system to make a perennial street lamp; highways can be used as night signposts; children in mountainous areas can study at night under fluorescent lights; and wind turbines can also be used on the roofs of small high-rise buildings in cities. Green power. Wind turbines for homes can not only prevent power outages, but also increase the interest in life. In tourist areas, border defenses, schools, troops and even backward mountainous areas, wind turbines are becoming a hot spot for people to purchase. Radio enthusiasts can use their own technology to serve mountain people in wind power generation, enabling people to watch television and lighting electricity in sync with the city, and also to make themselves rich through labor. ^[5]

In May 2009, the state invested 3 trillion yuan to support new energy, especially the wind power industry. The country strongly supports the development of wind power!
