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 locked to the speed of the

The stator is similar to a standard induction generator, consisting of a three-phase winding. The rotor, on the other hand, is a wound rotor, connected to the grid via slip rings and a converter. This design allows for variable speed operation and two-way power flow.See more on electricity-magnetism intechopen [PDF]
