Brief introduction of wind power generation

Wind power generation refers to the generation of electricity through the wind flowing in the air, which is a renewable energy source. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity. According to the current windmill technology, power can be generated at a breeze speed of about 3 meters per second (the degree of breeze), and output can be generated at a wind speed of 13 to 15 meters per second (the degree of trunk shaking). The advantages of wind power generation are: clean and safe, that is, it will not produce pollutants during operation and is harmless to various environments. With the continuous exploitation of fossil fuels such as natural gas and oil, the current price rises, and wind power generation has become an ideal choice in the medium and long term. With the progress of science and technology in recent years, the cost of wind power generation has been declining, and it is now close to the cost of traditional fossil fuel power generation. Reduce dependence on and use of exhausted fossil fuels and energy sources (such as oil and coal). An inexhaustible wind engine consists of five parts: wind wheel, nose, tail, rotator and tower. Among them, the wind wheel is the main component that converts wind into electricity. It looks like an electric fan or an airplane propeller and consists of one or several wings. The larger the diameter of the wind wheel, the more wind energy it receives, and the higher the power of the wind engine. See wind power station

The wind is generated because the sun heats the air on the surface, and the air becomes lighter when heated, and then rises. After hot air rises, heavy air with low temperature flows in from all directions, thus forming the flow of air, which is wind. Humans have long known how to use wind power in daily life, such as taking water with windmills, irrigating, grinding wheat and processing wood. Others such as wind-driven sailboats and gliders. The main purpose of modern wind energy is to generate electricity. 194 1 year, Vermont electric power company of the United States established the first large-scale wind turbine (1.25MW), and Japan is scheduled to build the largest wind turbine in Japan at present, with a total capacity of 60,000 tons, located in Shaolin Temple Village, Shimonoseki Peninsula, Aomori Prefecture, Japan, with a total investment of more than 100 billion yen. Due to the lack of fuel and the importance of environmental protection, all countries are developing wind power recently. Wind turbines are scattered all over Denmark, as shown on the left.
