1. Calculate the force exerted on each blade of the wind turbine: we know that the length of each blade of the Vista wind turbine is 44 meters, the air density is 1.225 kg/m3 and the wind speed is 11 .4 m. /s. According to the Bates formula, the thrust on each blade is the power F = (1/2) ρV2S, where ρ is the air density, V is the wind speed, and S is the blade area.
2. Calculate the total force on the wind turbine: The wind turbine has three blades, so the total force is three times the force on a single blade. Fenjiu 3. Calculate the output power of the wind turbine: Knowing the total force of the wind turbine and the transmission ratio of the wind turbine gearbox, the output power of the wind turbine can be calculated.
The formula for the power curve is 0.5*A*p*Cp*V^3 A is the area swept by the fan blades, P is the air density, V is the wind speed and Cp is the utilization rate of thewind power. Cp is related to wind speed, rotor speed and pitch angle. Generally, for fixed pitch and wind speed conditions, Cp will first increase and then decrease with speed.
