6 FAQs about [Generation hours and wind swept area]

How much power does a wind turbine generate?

How much power can a wind turbine extract?

Therefore, for a fixed power coefficient, the maximum power that wind turbines can extract depends on the air density, rotor blade swept area and the upstream wind speed. For instance, consider a simple case of a wind turbine design with a swept area of 2000 m 2 and a power coefficient of 0.40.

How do you calculate the power of a wind turbine?

The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3 Thus, the power available to a wind turbine is based on the density of the air (usually about 1.2 kg/m 3), the swept area of the turbine blades (picture a big circle being made by the spinning blades), and the velocity of the wind.

How do you calculate swept area of a wind turbine?

How much power does a 95 kW wind turbine produce?

Figure 2.7: Power curve of the Northwind 100C, 95 kW wind turbine.

Counterintuitively, the power output decreases if the wind speeds up past that point.

How does a wind turbine work?
