The power coefficient,, expresses what fraction of the power in the wind is being extracted by the wind turbine. It is generally assumed to be a function of both tip-speed ratio and pitch angle. Below is a plot of the variation of the power coefficient with variations in the tip-speed ratio when the pitch is held constant: Originally, wind turbines were fixed speed. This has the benefit that the rotor speed i.
