Wind is the fastest growing in the world's source of power, according to the National Renewable Energy Laboratory. For wind turbine power generation system, often referred to as wind turbines or tubular type turbine, wind energy into mechanical power. The simplest wind turbine has three basic parts: rotor blades, shaft and generator.    

    There are two basic types of blades, lifting style and towed. When the wind blows over lifting style blade, it will lead to the lift and rotate the blade. This style of blade is good at capturing the strong, the wind speed is good. Drag the blade flat panels. This is the type of old Dutch windmill blade. Windmill is not good at capturing the wind. Blade is made of glass fiber reinforced plastic, most wind tubular type turbines have two or three leaves, but there are also single-blade turbine.  

    Controller is used to start the tubular type turbine and its closure. Controller measures the speed and direction received anemometer, the instrument information. Disc brakes are used to stop the rotor in emergencies. Cabin structure housing the gearbox, low and high speed shafts, generator, controller and brake. Wind turbine towers can be independent or guy lines to help keep it rigid. Tower is a steel, concrete or steel frame.
