Isolated induction generator transients under different loading conditions

Abstract

This paper presents a new transient model of a standalone (isolated) Three phase self excited induction generator (SEIG). This model is based on direct phase quantities and is suitable to study the performance of the generator under any balanced or unbalanced conditions. It includes a general load as well as general excitation capacitor model. The model has the advantage of connecting or disconnecting the neutral points of the generator electrical system with both excitation capacitors and load. Furthermore, a more accurate magnetization curve is used. Moreover, the simulation results have been verified experimentally.
