Steady state analysis of three phase self excited induction generator using MATLAB GUI to feed single phase loads with three capacitor configuration

Abstract

This paper presents the analysis of a normal three-phase induction motor as a self-excited induction generator (SEIG) to feed single phase loads especially for energizing isolated locations using locally available renewable energy. In this star connected machine is considered with three capacitor excitation topology. This paper presents a user friendly software based solution for complete evaluation of steady-state behavior of SEIG under different operating conditions. The mathematical modeling of the machine is carried out and then simulated in MATLAB's Graphical User Interface (GUI) environment and active windows are created with these models. The simulated results obtained through the presented methodology have shown close agreement with experimental results thus validating the performance of this software tool.
