When the blades of a wind turbine are at the same wind speed and the same angle, is there any relati

The design of the blades is based on the speed of the motor.

First determine the speed and power of the generator, and then the size of the blades will be determined.

There is a formula for wind power generation: P=?ρ*π*R?*V?*Cp

ρ——air density;

V—— Wind speed;

Cp - wind energy utilization coefficient;

If it is the same generator and you make blades of different sizes, of course, theoretically, the generator with a larger blade area can run at the same wind speed Turn faster, because the output power P is larger at this time, as you can see from the above formula.

π*R? Here R is the radius of the blade sweep area.

The premise is that you are using the same motor.

Of course, bigger blades are not better, as overspeeding the motor will cause heat and damage.
