Among all wind power generators, the amount of electrical energy generated by each rotation of the wind power generator varies depending on the power of the wind power generator.
For example, the most common 2MW direct drive wind power generator, when the wind power is sufficient and stable, can generate 2,000 degrees of electricity every 60 minutes, and each rotation of the fan blades requires 3.5 seconds. , 60 minutes, is equal to 3,600 seconds, so the electricity generated by the generator per second is 0.56 kilowatt hours. Then, the electricity generated by the wind power generator fan for each rotation is 0.56 × 3.5 seconds, or 1.94 kilowatt hours. .
Detailed information
Principle of generator
The principle of wind power generation is to use wind energy to turn the blades of the wind turbine. , Thenthrough the gear machine increases the rotation speed to induce 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 unstable air volume, 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.
