Wind power generation fan refers to a wind turbine.
Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work drives the rotor to rotate and finally outputs alternating current. Wind turbines generally include a wind wheel, a generator, a director, It is composed of tower, speed limit safety mechanism and energy storage device.
The working principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to generate electricity.
Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
Wind turbines, like hydraulic machinery, have played an important role in the development of productivity as a source of power to replace human and animal power. The widespread application of electromechanical power in modern times and the discovery of oil fields in the Middle East in the 1950s slowed down the development of wind turbines.
Generator principle:
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser. to cause the generator to generate electricity. Based on current wind turbine technology, power generation can begin at a breeze speed of approximately three meters per second (the level of gentle wind).
Due to the unstable air volume, the wind turbine outputs alternating current of 13 to 25V, which must be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy. . Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
