The Basics Of V F Control In Variable Frequency Drives

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]
