Betz’s law

Betz’s Law describes the maximum power that a wind turbine can extract from the wind, regardless of its aerodynamic design. The power output of a wind turbine depends on the interaction of its rotor with the wind. In 1919, German…

Wind turbine power curve

The wind turbine power curve contains the optimal operating points. Notable wind speeds such as cut-in wind speed, rated wind speed, and cut-out wind speed define five operating zones. These zones determine the dynamic behavior of the wind turbine. Power…
