TLDR
In this article, the transient behavior of a symmetrically loaded DFG after a three-phase short circuit is presented, where both speed and rotor excitation voltage and frequency remain unchanged during short circuit.Abstract:
The doubly fed induction generator (DFG) is a variable-speed constant-frequency generator operating in either subsynchronous or supersynchronous mode. The transient behavior of a symmetrically loaded DFG after a three-phase short circuit is presented. Both speed and rotor excitation voltage and frequency remain unchanged during short circuit. The complete mathematical model of the transient state and experimental results are given, along with the transient state equivalent circuit. >read more

Control of a doubly fed induction generator in a wind turbine during grid fault ride-through
TL;DR: In this paper, the ability of a doubly fed induction generator (DFIG) in a wind turbine to ride through a grid fault and the limitations to its performance were analyzed. But the fundamental difficulty for the DFIG in ride-through is the e.m. induced in the machine rotor during the fault, which depends upon the d.c. and negative sequence components in the stator flux linkage and the rotor speed.

On the theory of 3-phase squirrel-cage induction motors including space harmonics and mutual slotting
TL;DR: In this article, the authors derived general equations for squirrel-cage induction motors based on the real geometry of the motor and derived free angles to simplify the set of equations when the specific geometrical properties of both types of machines fundamentally can be divided are taken into account.
