Pitch-Controlled Variable-Speed Wind Turbine Generation
www.nrel.govIn 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 ...

Application of wind energy - An-Najah National University
www.najah.eduThe wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Wind turbine types: 1- Vertical axis wind turbine (i.e. Darius wind turbine) Advantages of vertical wind turbines Vertical wind turbines are easier to maintain because most of their moving parts are located near the ground.
Dynamic Models for Wind Turbines and Wind Power Plants
www.nrel.govJan 11, 2008 · early 1980s. This was a period when wind turbine technology was starting to become viable, and concerns about the effects of large-scale WPPs on the grid began to be voiced [13–18]. The intermittent and variable nature of wind, the reliance of most wind power plants on induction generators, and the fact that wind generation tends to
