Pitch-Controlled Variable-Speed Wind Turbine Generation

Pitch-Controlled Variable-Speed Wind Turbine Generation

www.nrel.gov

In the early development of wind energy, the majority of wind turbines were operated at constant speed. Recently, the number of variable-speed wind turbines installed in wind farms has increased and more wind turbine manufacturers are making variable-speed wind turbines. This paper covers the operation of variable-speed wind turbines with pitch ...
