Virtual laboratory environment using MATLAB-GUI for teaching of induction generators

This paper presents an user friendly software tool based on MATLAB Graphical User Interface (GUI) to educate analytically the performance of an induction machine as generator under different configurations like Self Excited Induction Generator (SEIG) and Grid Connected Induction Generator (GCIG). The operation of induction machine as SEIG and GCIG is very tricky to understand, however the steady state analysis of induction generator is vital in the operation and control of present day power grid with large wind energy penetration. Keeping this in mind, in order to make the teaching, self-learning and analysis of induction generator simple, a front end visual tool is created employing the GUI capabilities of MATLAB and embedding the mathematically modelled operating conditions in MATLAB code. The results of the analysis are displayed in this tool as plots and phasor diagram with necessary options to select and view the particular result. This software tool on induction generator assists in teaching, facilitates self-learning of students and also helps in better analysis of induction machine in industries. Moreover, an overall report of the performance analysis of the induction generator under different conditions can also be generated in PDF format.
