A comprehensive MATLAB GUI tool for modeling and performance analysis of 3-phase SEIG

摘要

This paper presents an easy to use MATLAB GUI based tool for comprehensive analysis of 3-phase SEIG. The software comprises of four sections that includes comparative modeling, performance analysis, per unit to actual value conversion and experimental validation of the simulated result. Steady state performance analysis of a 3-phase SEIG is generally done through the proposed mathematical modeling. The impedance model can be reduced in terms of two nonlinear simultaneous equations consisting of unspecified variables as magnetizing reactance Xm and generated frequency F. A comparative GUI methodology has been employed to evaluate the parameters using conventional Newton Raphson technique and novel Fsolve technique. The steady state performance analysis of SEIG becomes uncomplicated once the values of Xm and F are explicitly evaluated. Active windows have been created for assessing the impact of distinct circuit parameters on the terminal voltage. A per unit to actual value conversion GUI tool for distinct SEIG connections have also been integrated for proper understanding in industrial applications. The yielded outcomes of the designed software tool are compared with the experimental results are found to be in close agreement. The GUI approach is found to be user friendly, application specific, facile and simpler.
