Characteristics of Variable-Speed Cascaded Induction Generator System with Reduced Harmonic Currents

Abstract

A novel brushless variable-speed induction generator system is proposed for small-scale hydroelectricity. The stator of the second induction generator has six-phase windings connected with a twelve-pulse rectifier system to reduce adverse effects of lower-harmonic currents. The simulation results show that the first induction generator can produce nearly sinusoidal currents.
