OverviewIntroductionHistoryDoubly fed induction generatorExternal links

Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locke

Doubly-fed Induction Generators – Wind Turbines

This is where Doubly-fed Induction Generators come into play, as they allow the generator output voltage and frequency to be maintained at constant values, no matter the generator rotor speed and thus, no matter the
