Principle of wind power

1. What is wind power?

Wind power refers to the conversion of wind energy into electricity, its full name is wind power. The kinetic energy of the wind is converted into mechanical kinetic energy, and the mechanical energy is converted into electric kinetic energy, which is wind power. Depending on the installation area, wind power can be divided into onshore wind power and offshore wind power. Wind is a pollution-free and pollution-free energy, it is not only environmentally friendly, but also can provide a lot of electricity, so countries pay more and more attention to wind energy.

2. The principle of wind power generation

The principle is to use the wind to drive the windmill blade to rotate, and then increase the rotating speed through the speed reducer to promote the generator to generate electricity. With current windmill technology, a breeze speed of about three meters per second can start generating electricity.

3. Wind power output

The wind generator is unstable because of the air volume, so its output is 13 ~ 25V of alternating current, must be rectified by the charger, and then charge the battery, so that the electricity generated by the wind generator becomes chemical energy. Then use the inverter power supply with protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.

4. Wind farms

A wind farm (referred to as a wind farm) is a large grid-connected wind turbine installed in a site with good wind energy resources, arranged in an array according to the terrain and the main wind direction, forming a cluster to supply power to the grid. According to the location can be divided into offshore wind farms, onshore wind farms.
