Dynamic and Steady State Modelling of the Doubly Fed Twin Stator Induction Generator With Core Loss.

Abstract

This paper presents dynamic and steady state models of the brushless doubly fed twin stator induction machine (BDFTSIM) with emphasis on its use as a generator. The dynamic models are presented in the general reference frame. The models include the effects of core loss on both the stator and the rotor. The frequency on the rotor of the BDFTSIM is much higher than in a standard induction machine so that core losses can not be neglected. The performance analysis indicates the feasibility of the BDFTSIM as a variable speed wind generator
