Control of grid connected induction generator using naturally commutated AC voltage controller

The paper presents a complete analysis of an induction generator linked to a power network through an AC voltage controller utilizing anti-parallel thyristors. The performance characteristics regarding the harmonic contents, active power, reactive power, power factor and efficiency have been computed. These characteristics have been determined with the help of a novel abc-dq circuit model. The model possess the advantages of both the dq and direct phase models.
