MATLAB Based Steady State Analysis of Self Excited Induction Generator

This paper presents a MATLAB based technology to predict the steady state behaviour of Self Excited Induction Generator. Taking into consideration the fact of rapid growing popularity of Self Excited Induction Generator research has been centered on analysis, control and design of the same for standalone applications. In this paper to obtain relevant performance equations, symmetrical component theory is used to obtain performance equations. Steady state analysis is carried. To suit the computer simulation manageable equations were derived by incorporating some valid simplifications from the analysis. Non linear parameters were chosen corresponding to appropriate saturation levels. Results of this simulation help us in realizing the usage of 3-phase self induction generator in standalone power generation. Efficiency of MATLAB softwares is demonstrated for this application in contrast to earlier reported work.
