Analysis of a Saturated Multi-Phase (Six-Phase) Self-Excited Induction Generator

Abstract

The present paper is concerned with the application of the equations of a saturated smooth air-gap machine to the analysis of the transient behavior of a multi-phase (six-phase) self-excited induction generator (SEIG). In the analytical model (d-q axis model), the effects of common mutual leakage inductance between the two three-phase winding sets have been included. A detailed experimental investigation of self-excitation process, loss of excitation and re-excitation, switching-in of pure resistive load without, and with series compensation (short shunt) is also included in this paper.
