The wind energy utilization coefficient of the wind turbine is expressed by CP. Theoretically, the CP will not exceed 0.593. The maximum power generation efficiency of the current mainstream wind turbines (the highest utilization rate is around 10 meters/second) is generally around 0.45, while the seventh level wind is 14 -17 meters/second, which exceeds the troublesome wind speed of the fan, and the utilization rate will begin to decrease, around 0.2-0.4. The sweep area is related to the impeller diameter. The current mainstream impeller diameters are 70, 80, 93, 105, 115 meters, etc. You can calculate the corresponding sweep area.
In addition, the current mainstream wind turbine power is 1500, 2000, 3000, 5000, 6000KW, etc., of which 1500 and 2000 account for 80%.
