It depends on several factors
1. Windmill configuration
2 Wind conditions
For example, if the diameter is 60 meters, the wind speed is greater than 38 kilometers per hour, the capacity of Power generation can also reach 2,000 kilowatts.
Generally speaking, level 3 wind power is valuable for use. However, from an economic and reasonable point of view, wind speeds above 4 meters per second are suitable for electricity generation. According to measurements, a 55 kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts when the wind speed is 6 meters; per second, only 16 kilowatts; and when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the greater the forcethe stronger the wind, the greater the economic benefits.
As mentioned in the answer, only when the wind speed is greater than 4 meters/second can it have the value of generating electricity.

1.5 MW For a wind turbine, the generator spins about 1,800 times per minute, generates 1,500 kilowatt hours of electricity per hour, and the turbine spins about 18 times per minute . This is directly linked to the ability tounity.
Generally speaking, level 3 winds are valuable. However, from an economic and reasonable point of view, wind speeds above 4 meters per second are suitable for electricity generation.
According to measurements, a 55 kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts; wind speed When the wind speed is 6 meters per second, it is only 16 kilowatts; when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the stronger the wind force, the greater the economic benefits.
Detailed information
A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces ae alternative production. current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting 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. by 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 thermal energy generator that uses the sun as a heat source and the atmosphere as a heat source. work.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energyintended 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.
In the early 1970s, in Due to the “oil crisis”, energy shortages have arisen. People have become aware of the instability and limitations of conventional fossil energy supplies, so the search for clean and renewable energy has become a key issue in the modern economy. world. an important subject. As a renewable and non-polluting natural energy source, wind energy has once again attracted attention.
