One rotation of wind power can generate 100 kilowatt hours. For a 1.5 megawatt wind turbine, the generator spins about 1,800 revolutions per minute, producing 1,500 kilowatt hours of electricity per hour. The turbine rotates 18 times per minute. This is directly related to the unit's capacity. According to measurements, a 55 kW wind turbine has an output power of 55 kW when the wind speed is 9.5 m 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, the power is only 16 kilowatts; when the wind speed is 5 meters per second, the power is only 9.5 kilowatts. It can be seen that the greater the wind force, the greater the economic benefits.
How many kilowatt hours of electricity does wind power produce per cycle?
A conventional sized wind turbine can produce on average1,200 kilowatt hours of electricity per hour. Calculated, one rotation of the windmill can generate approximately 1 kilowatt hour of electricity. Wind turbines are limited by material structure and are designed to have maximum rotational speed. Excessive speed can damage it or even destroy it completely.
The conversion of wind energy into electrical energy is also a complex process. In traditional wind turbines, after the blades rotate, the rotation speed is increased through several sets of gears such as speed multipliers to drive the generator to produce electricity. However, this method consumes a lot of energy, so another technology has been developed, direct drive permanent magnet technology.
The wind turbine is 1,500 kW. At full power, it makes around 17 revolutions per minute. If you calculate it, one turn is 1.47 kilowatt hoursre electricity. For a 1.5 MW wind turbine, the generator turns. about 1,800 revolutions per minute and generates electricity in an hour; the turbine rotates approximately 18 times per minute. This is directly related to the size of the unit.
