The formula of the power curve is 0.5*A*p*Cp*V^3 A is the swept area of the fan blade, P is the air density, V is the wind speed, and Cp is the wind energy utilization rate. Cp and wind speed, wind wheel speed, The pitch angle is related. Generally, for fixed pitch and fixed wind speed conditions, Cp will first increase and then decrease with the rotation speed
Suppose the wind speed v air density ρ and the generator blade radius R reach within t time The air mass on the fan blade is m=ρπR^2Vt, and the energy obtained by the fan blade is E=1/2mv^2=1/2ρπR^2V^3t
P0=E/t=1/2ρπR^2V ^3
Suppose the generator efficiency η
The generated power of the wind turbine P=1/2ηρπR^2V^3
