MATLAB-Simulink Model of a Stand-Alone Induction Generator

Abstract

This paper presents modeling, simulation and optimization of an induction generator. The induction machine is represented with a saturation adaptive induction machine dynamic model having state variables expressed in terms of fluxes and reactances. Transients of machine self-excitation under a three-phase load application are simulated using a Simulink block diagram. The magnetization reactance and generated frequency are computed by constrained minimization method for generator operating mode by using the function fmincon from Matlab Optimization Toolbox
