Wind power formula:
Cp×1/2ρAU?
Where: ρ is the air density, A is the surface area of the wind wheel (more the wind wheel, the higher the production capacity), U is the current wind speed
Cp is the wind energy utilization coefficient, that is, the efficiency of the wind turbine in the conversion of wind energy into mechanical energy (related to the aerodynamic performance of the wind turbine blades)
According to energy conservation, the above factors are the fundamental factors affecting electrical energy.
The size of the electrical power is mainly related to these factors
The rated power of the wind turbine: assume that the wind speed v the air density ρ and the radius of the generator blades R to reach the fan blade within a time t The air mass above m=ρπR^2Vt, the energy obtained by the fan blades is E=1/2mv^2=1 /2ρπR^2V^3t
P0=E/ t=1/2ρπR^2V^3
Assume that the generator efficiency η
The power generated by the wind turbine P=1/2ηρπR^2V^3
