We acted as a lookout kinetic energy into mechanical energy, then mechanical energy into electrical energy, which is wind power. Wind power needs a device called a wind turbine. This wind turbine, in general can be divided into the wind wheel (including the rudder), generator and tower three parts.

Wind Wheel is the lookout of the kinetic energy into mechanical energy are important components, which consists of two (or more only) the composition of the propeller-shaped impeller. When the wind blows the blades, the blades to generate gas-powered wind wheel rotation. The role blade material requirements, high strength, light weight, the current multi-purpose glass fiber reinforced plastic or other composite materials (such as carbon fiber) to produce.

As the wind speed is relatively low round, but the size and direction of the wind always changing, which in turn makes speed instability; So, before driving generators must also attach a generator to speed up to rated speed of the gear box, coupled with a speed governor to maintain a stable body, and then connected to the generator on. In order to maintain the wind wheel has always been aligned to achieve maximum wind generators, need to install behind the wheel in the wind like a weathervane of the rudder.

Tower is the bearing the wind wheel, rudder and wind generator architecture. It is usually built much higher in order to gain a larger and more uniform wind, but also have enough strength. Tower height as the ground effects of obstacles on the wind speed, as well as the wind wheel diameter sizes, usually in the 6-20 m range.

Generally speaking, the three have used the value of the wind. But from the perspective of economic rationality, the wind speed is greater than 4 meters per second, only suitable for power generation. According to the determination of a 55-kilowatt wind turbine, when the wind speed was 9.5 meters per second, units of the output power of 55 kW; when the wind speed of 8 meters per second, the power of 38 kilowatts; wind speed of 6 meters per second, the only 16 kW; and 5 meters per second wind speed when only 9.5 kilowatts. The greater the wind can be seen, the greater the economic benefits.

China's wind resources are extremely abundant in most areas, the average wind speeds are more than 3 meters per second, especially in the northeast, northwest, southwest plateau and coastal islands, the average wind speed greater; in some places, one year more than a third The times are windy days. In these areas, the development of wind power generation is very promising.

Wind is no pollution sources of energy. And it is inexhaustible. For the water shortage, lack of fuel and inaccessible coastal islands, pastoral grasslands, mountains and highland areas, according to local conditions the use of wind power, ideal for bright prospects.
