Performance analysis of three-phase self-excited induction generator under single-phase load

This paper presents a steady performance analysis of an isolated three-phase self-excited induction generator which employs a three-phase winding in series connection with two capacitors and supplies for single-phase load. Performance analysis is derived by the method of symmetrical components, from which the input impedance of the generator can be determined. The voltage unbalance factor is computed to ensure the minimum unbalance state. The theoretical analysis is validated by simulation results of a 2.2 kW induction machine.
