1.94 kWh.
It takes 3.5 seconds for the fan blades to rotate once, so the electricity generated by the generator per second is 0.56 degrees, then the electricity generated by the wind power generator fan for each revolution is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.
A 48 meter circle of blades generates 1.94 kilowatt hours of electricity. According to relevant information, when the wind power is sufficient and stable, the wind motor can generate 2,000 degrees of electricity every 60 minutes, and it takes 3.5 seconds for the fan blades to rotate once for 60 minutes , therefore the generator Le. The amount of electricity generated per second is 0.56 kilowatt hours, so the electricity generated by each rotation of the blades is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity generated by wind power in one run.
