The power output of a wind turbine varies with wind speed and every wind turbine has a characteristic power performance curve. With such a curve it is possible to predict the energy production of a wind turbine without considering the technical details of its various components. The power curve gives the electrical power output as a function of the hub height wind speed. The figure presents an example of a power curve for a hypothetical wind turbine. The performance of a given wind turbine generator can be related to three key points on the velocity scale:
Cut-in speed: The minimum wind speed at which the machine will deliver useful power.
Rated wind speed: The wind speed at which the rated power (generally the maximum power output of the electrical generator) is reached.
Cut-out speed: The maximum wind speed at which the turbine is allowed to deliver power (usually limited by engineering design and safety constraints).
