About Doubly-fed generator for wind turbines
Doubly fed electric machines, Doubly fed induction generator (DFIG), or slip-ring generators, are electric motors or electric generators, where both the field magnet windings and armature windings are separately connected to equipment outside the machine.By feeding adjustable frequency AC power to the field.
Doubly fed electrical generators are similar to, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed.This is useful for large.
With its origins inwith multiphase winding sets on the rotor and stator, respectively, which were invented byin 1888,the rotor winding set of the doubly fed electric machine is connected to a selection of resistors via multiphase.

6 FAQs about [Doubly-fed generator for wind turbines]
What is a doubly fed generator for wind turbine?
Doubly fed generator for wind turbine. 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.
What is doubly fed induction generator?
One of the generators that are widely used in MW scales wind turbines is the doubly fed induction. This paper presents control method which is called the grid voltage-oriented vector control method… 2013 4th IEEE International Symposium on Power… Doubly Fed Induction Generator (DFIG) is widely used for wind turbine electricity generation.
Is double fed induction generator suitable for grid-connected wind energy conversion system?
This paper presents the control strategies and performance analysis of doubly fed induction generator (DFIG) for grid-connected wind energy conversion system (WECS). The wind power produces environmentally sustainable electricity and helps to meet national energy demand as the amounts of non-renewable resources are declining.
What is a doubly fed generator?
Instead of the usual field winding fed with DC, and an armature winding where the generated electricity comes out, there are two three-phase windings, one stationary and one rotating, both separately connected to equipment outside the generator. Thus, the term doubly fed is used for this kind of machines.
What is advanced control of doubly fed induction generator for wind power systems?
Advanced Control of Doubly Fed Induction Generator for Wind Power Systems is an ideal book for graduate students studying renewable energy and power electronics as well as for research and development engineers working with wind power converters.
What is a doubly fed induction generator (DFIG)?
