Fundamentals of Wind Turbines | Wind Systems Magazine

Turbine power increases with the cube of wind velocity. For example, a turbine at a site with an average wind speed of 16 mph would produce 50 percent more electricity than the same turbine at a site with average wind speeds of 14 mph. These two fundamental physical relationships are behind the drive to scale up the physical size of turbines.

The effective power is the difference between the two wind powers: If the difference of both speeds is zero, we have no net efficiency.

How does a wind turbine work?

First, the power output is zero and the turbine blades are locked until the “cut-in” wind speed is reached, with sufficient power to generate electricity. Once the wind speed exceeds the “cut-in” speed, the turbine blades are allowed to spin, and the turbine generates power output increasing with the third power of the wind speed.
