A Novel MATLAB Graphical User Interface Based Methodology for Analysis, Design and Capacitor Estimation of Self Excited Induction Generators

The steady state analysis of self excited induction generator (SEIG) is vital for proper implementation of induction machine operation as a generator in a stand alone mode through appropriate modeling. This paper presents a user friendly software based solution for complete evaluation of steady-state behavior of SEIG and a design tool to estimate the capacitance requirement under different operating conditions. It can also predict the performance of SEIG with different types of prime movers such as oil / bio engines, wind and small hydro turbines. 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. As a basis for developing an attractive and easy to use design tool, some of MATLAB´s GUI operations are implemented in creating an active link with these models. The simulation results obtained through the presented methodology are validated through relevant experimental verification.
