Converting the kinetic energy of wind into mechanical kinetic energy and then converting mechanical energy into electric energy is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity.

According to the current windmill technology, power generation can be started at a breeze speed of about three meters per second (the degree of breeze). Wind power generation is becoming a worldwide craze, because wind power generation does not need to use fuel, nor does it produce radiation and air pollution.

Due to the unstable air volume, the wind generator outputs 13 ~ 25V alternating current, which must be rectified by a charger, and then the battery is charged, so that the electric energy generated by the wind generator becomes chemical energy. Then the chemical energy in the battery is converted into AC 220V commercial power by an inverter power supply with a protection circuit to ensure stable use.

Extended data:

Classification of wind turbines:

1, horizontal axis wind turbine, the rotation axis of the wind wheel is parallel to the wind direction;

2, vertical axis wind turbine, the rotation axis of the wind wheel is vertical to the ground or airflow direction.

Advantages:

1, clean, good environmental benefits;

2, renewable, never exhausted;

3. The capital construction period is short, which can be built on land or at sea;

4. Flexible installed capacity and low operation and maintenance cost.
