As a kind of new power generation system, wind power generator has the advantage of inexpensive, reliable and no greenhouse gas emissions. The installed capacity of wind power generator system has been widely used in the world and got increasingly growth of more than 30 percent per year. It has formed a global industry which has more than fifty billion annual outputs. At present, most of the installed wind power systems are large-scale wind turbine systems with adoptions of MW level connected with power grid. Technology in this industry has matured through continuous improvement. As to the small wind power systems for independent power supply in remote areas it also need to overcome many technical difficulties to be widely used. In other word, to solve their electricity demand is just around the corner. The use of small wind power systems for local load electricity has the following advantages: first, this system can reduce the huge one-time investment, second, it can remove the greenhouse gas emissions from thermal power system, and at last, it can also improve the environment and the energy structure of the rural areas. All of these are benefit for our sustainable development.
The technical document from the Top Wind has given us many useful information for the principle of the small wind generator. The Top Wind is the best wind turbine manufacturer in China. With these years development, this company has sold their high quality wind solar hybrid power system and wind power alternator to many countries. From the technical detail, we have known that wind turbine is a kind of system which can convert wind energy into mechanical energy. From the point of view of energy conversion, wind turbine consists of two parts: one is the wind turbine whose function is to convert wind energy into mechanical energy; the other is the generator who has the function of converting mechanical energy into electricity.

Small wind power systems are generally consists of the wind wheel, generator, rudder and electrical part constitutes. Most of the conventional small wind turbines are formed by the induction generator or permanent magnet synchronous generator, AC/DC converters, battery, and the inverters. Blowing in the wind, the wind wheel spinning and transform the air power into mechanical energy. The wind wheel hub fixed to the generator shaft and its rotation make the generator shaft revolves. In that way a permanent three-phase generator can be driven by the shaft and generate the three-phase alternating current. The generator current and voltage is unstable because of the flickering wind. The electricity current gonging through the controller rectifier, become a direct current with certain voltage and finally charge the battery. The output from the battery is transformed into 220V AC power by an inverter and supply to the user home appliances.
Wind turbine is divided into grid-connected and off-grid wind turbine according to the different applications. Off-grid wind turbine is also known as the independent operation of solar panel which is generally less power and applied in the off-grid area. Independent operation of the wind turbine power generation system is generally composed by the wind turbine battery and other control devices. It can be a few kW systems to solve a village power supply or of tens to hundreds W wind turbine systems to solve a house-supply.
Top wind is a respectfful and dynamic company in new energy field, aims to provide premium quality solar panel manufacturer and wind-solar hybrid system solutions.
