Variable-speed wind turbine
A variable-speed wind turbine is a wind turbine whose rotor speed continuously adjusts to the wind for near-maximum efficiency, using power electronics; the DFIG and fully rated converter designs dominate.
Vensys
Vensys is a German wind turbine manufacturer based in Neunkirchen, Saarland, founded in 2000 as a university spin-off, that builds gearless turbines with permanent-magnet direct-drive generators.
Vertical-axis wind turbine
A vertical-axis wind turbine (VAWT) is a wind turbine whose axis of rotation is vertical, unlike horizontal-axis turbines, with drag-based Savonius and lift-based Darrieus designs.
