Abstract

This paper presents the operation performance of an isolated self-excited induction generator (SEIG) under unbalanced loading conditions including the effects of neutral line. An approach based on three-phase induction machine model is employed to derive dynamic equations of the studied SEIG. Steady state characteristics such as unbalanced voltage factor, unbalanced current factor and efficiency of studied SEIG are examined and compared for three different passive loads and three kinds of neutral connection. Experimental results from a laboratory 1.1 kW induction machine driven by a DC motor are performed to confirm the feasibility of the proposed approach.
