Matlab/Simulink Based on αβ Modeling of Self-Excited Induction Generator

Abstract

This paper presents modeling of stand-alone self­ excited induction generator used to operate under variable speeds prime mover. The proposed dynamic model consists of induction generator, excitation capacitor and inductive load model are expressed in stationary α-β reference frame with the actual magnetizing saturation curve of the induction machine. The aim of this research is to developed and designs of the self-excited induction genera tor and to describe the simulation results using a Matlab/Simulink. The system has been simulated to verify its capability such as build-up voltage and stator flux linkage responses, stator phase current, electromagnetic torque and variation of magnetizing inductance both during dynamic and steady-state with variable speed prime mover.
