Wind power generation fan refers to a wind turbine.
Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally include a wind wheel, a generator, a. director, it is composed of a tower, a speed limit safety mechanism and an energy storage device.
The operating principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. driving the wind wheel shaft to produce electricity.
Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a generator using thermal energy which uuses the sun as a heat source and the atmosphere as a working fluid.
Wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy intended to replace human and animal energy. The widespread application of electromechanical power in modern times and the discovery of oil deposits in the Middle East in the 1950s slowed the development of wind turbines.
Principle of generator:
The principle of wind power generation is to use wind energy to rotate the blades of the windmill. wind, then increase the rotation speed. using a speed multiplier to cause the generator to produce electricity. According to current wind turbine technology, electricity production can start at a breeze speed of around three meters per second (the breeze level).
Due to the volume ofIn unstable air, the wind turbine produces 13-25V alternating current, which needs to 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 with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.
