GOLDWIND is good. Clean, good environmental benefits, high power generation efficiency, low maintenance and operation costs, good grid connection performance, high availability and other superior properties, it is deeply welcomed and recognized by customers. Wind turbines are electrical equipment that convert wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a director (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
Among all wind energy generators, the amount of electrical energy generated by each rotation of the wind energy generator varies depending on the power of the wind energy generator.
For example, the most common 2MW direct-drive wind energy generator, when the wind energy 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 3600 seconds, so the electricity generated by the generator per second is 0.56 kilowatt-hours. Then the electricity generated by the fan of the wind energy generator for each rotation is 0.56 × 3.5 seconds, which is 1.94 kilowatt-hours.

Generator principle
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then through the The speed machine increases the speed of rotation to prompt the generator to generate electricity. According to current wind turbine technology, power generation can start at a breeze speed of about three meters per second (the level of breeze).
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.
