Wind turbine variable speed constant frequency system

Wind turbine variable speed constant frequency system

For variable speed wind turbines, one of two types of generators can be used: a (doubly fed ) or an FRC (fully rated converter). A DFIG generator draws from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure. A DFIG configuration will require the generator to be a wound rotor; squirrel cage rotors cannot be used for such a configuration. [PDF Version]

Does the wind turbine suction face the wind

Does the wind turbine suction face the wind

Suction/Leeward Surface: The suction or leeward surface of the blade is the surface facing away from the wind (hence leeward). .
