Abstract

This paper presents the results of using an eigenvalue scheme to determine the excitation capacitance required for an autonomous three-phase self-excited induction generator (SEIG) feeding a single-phase load. Three different stator configurations, single-phasing mode of operation, Steinmetz connection I, and Steinmetz connection II, are respectively employed. An approach based on three-phase induction-machine model is employed to derive dynamic equations of the studied SEIG. Both minimum and maximum values of the single excitation capacitance required for the studied SEIG under three configurations are obtained and compared. Experimental results obtained from a laboratory 1.1 kW induction machine driven by a DC motor are also performed to validate the effectiveness of the analyzed results
