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. In this software package the complex nonlinear equations are solved by a numerical based routine `Fsolve' in the tool box of MATLAB to find the values of saturated magnetizing reactance Xm and the output p. u. frequency F for the given values of machine parameters. Some of MATLAB's GUI operations are implemented in creating an active link with these models. The simulation results obtained by the presented methodology are also compared with the corresponding experimental values and are found to be in very good agreement.
