In this article, a power control system for a doubly fed wound rotor induction generator was developed, which applies a control method using a rotating reference frame fixed on the gap flux of the generator, and can control active and reactive power independently and stably.Abstract:
A power control system for a doubly fed wound rotor induction generator has been developed. This power control system applies a control method using a rotating reference frame fixed on the gap flux of the generator, and can control active and reactive power independently and stably. The characteristics of the control system have been proved by experiment. Harmonic currents fed to the rotor windings are transmitted to the stator winding changing its frequency. The transmitting characteristics of the harmonic currents have been analyzed and verified by experiments. >read more
