The principle of wind power generation is to use the wind to drive the rotation of the windmill blades, and then increase the speed of the rotation through the speed increaser to promote the generator to generate electricity. According to the current windmill technology, about three meters per second (the degree of breeze) above the wind speed, you can start generating electricity.
Wind power is forming a craze in the world, there is no fuel problem for wind power generation, and there is no radiation or air pollution.
Wind power is very popular in countries such as Finland and Denmark; China is also strongly promoting it in the western region. The wind turbine consists of a nose, a swivel, a tail and a blade. Each part is important, and the functions of each part are: the blade is used to receive the wind and is converted into electric energy by the nose; the tail makes the blade always face the direction of the wind to obtain the maximum wind energy; the swivel enables the head to flexibly rotate to achieve The function of adjusting the direction of the tail wing; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic lines of force to generate electric energy.
Wind turbines are unstable due to the amount of wind, so the output is AC power varying from 13 to 25V. It must be rectified by the charger, and then the battery is charged, so that the electric energy generated by the wind turbine becomes chemical energy. Then use the inverter power supply with protection circuit to convert the chemical energy in the battery into AC 220V mains to ensure stable use.
It is generally believed that the power of wind power is completely determined by the power of the wind turbine. It is always wrong to buy a larger wind turbine. Current wind turbines only charge the battery, and the battery stores the electrical energy. The amount of electricity that people ultimately use is more closely related to the size of the battery. The magnitude of the power depends more on the amount of wind, not just the power of the head. In the Mainland, small wind turbines will be more suitable than large ones. Because it is more easily driven by small winds to generate electricity, the continuous small wind will provide more energy than the current wind. When there is no wind, people can also use the power from the wind. That is to say, a 200W wind turbine can also be used with the large battery and the inverter to obtain 500W or even 1000W or even more power output.
The use of wind turbines is the constant conversion of wind energy into the standard utility power used in our homes. The degree of savings is obvious. The cost of a household's electricity consumption is only 20 yuan per year. Today's wind turbines have improved significantly over the performance of a few years ago. In the past, it was only used in a few remote areas. The wind turbine was connected to a 15W light bulb for direct use, which would cause damage to the bulb. Nowadays, due to technological advancement, using advanced chargers and inverters, wind power generation has become a small system with a certain technological content, and can replace normal commercial power under certain conditions. The mountain area can use this system to make a street lamp that does not cost money all the year round; the highway can be used as a road sign for the night; children in the mountain can study in the evening under the fluorescent lamp; wind power motors can also be used in the small high-rise roof of the city, which is not only economical but also real Green power supply. Household wind turbines not only prevent power outages, but also increase the interest of life. Wind turbines are becoming a hotspot for people in tourist attractions, border defenses, schools, military units and even remote mountainous areas.
