A generalized dynamic and steady state analysis of Self Excited Induction Generator (SEIG) based on MATLAB

Abstract

This paper presents a Matlab based generalized algorithm to predict the dynamic and steady state performance of Self Excited Induction Generators (SEIG) under any combination of speed, excitation capacitor and loading. The popularity of Self Excited Induction Generator and widespread use in stand-alone applications is centered on analysis, control and design suitable for the application. Three different methods, operational equivalent circuit, Newton-Raphson and equivalent impedance method are used for analyzing under any given situation. The excitation capacitors and load combined with the d-q model of the machine, together with the saturation is used to predict the dynamic behavior of the SEIG. The algorithms are implemented as MATLAB user friendly Tool boxes resulting in considerable simplification over earlier methods.
