Fundamentals of Wind Turbines | Wind Systems Magazine

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.

Wind power

The relationship between wind speed and power for a typical wind turbine is shown in Figure 2. Turbines are designed to operate within a specific range of wind speeds. The limits of the range are known as the cut-in speed and cut-out speed. The cut-in speed is the point at which the wind turbine is able to generate power.

How Do Wind Turbines Work? | Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

How wind speed affects turbine power production

This is typically around 3 meters per second (~7 miles per hour) for turbines installed by One Energy. As the wind speed continues to climb, it will eventually reach what is called the "rated" wind speed, which is 11.5 meters per second (24.5 miles per hour). This is when the turbine has reached its maximum power production capacity.

Wind energy

Today''s new wind power projects have a turbine capacity in the 3-4 MW range onshore and 8-12 MW offshore. The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed.
