Performance analysis of a self-regulated self-excited single-phase induction generator using a three-phase machine

A performance analysis of a modified self-regulated self-excited single-pha se induction generator is presented. This generator consists of a three-pha se squirrel-cage induction machine and three capacitors connected in series and parallel with a single-phase load. By utilizing this three-phase syste m as a single-phase generator, in addition to improved voltage regulation, the inherent vibration and noise in the generator can be significantly redu ced. Using an equivalent circuit model, the generator steady-state characte ristics are theoretically predicted, and confirmed through experiment. Thes e results are useful in optimizing generator performance.
