Hereof, what is a doubly fed induction generator?

The doubly-fed induction generator (DFIG) system is a popular system in which the power electronic interface controls the rotor currents to achieve the variable speed necessary for maximum energy capture in variable winds.

One may also ask, how do induction generators work? Principle of operation. An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. This causes the stator flux to induce rotor currents, which create a rotor flux with magnetic polarity opposite to stator.

Similarly, why is it called doubly fed induction generator?

A Doubly Fed Induction generator as its name suggests is a 3 phase induction generator where both the rotor and stator windings are fed with 3 phase AC signal. It also consists of a multiphase slip ring assembly to transfer power to the rotor. It is typically used to generate electricity in wind turbine generators.
