Steady State Analysis and Performance of an Isolated Self-Excited Induction Generator

A general analysis to predict the steady state performance of an isolated self-excited induction generator feeding a balanced R-L load is presented. In the analysis the effect of machine core losses has also been considered. It is shown that besides voltage and frequency the analysis can be used to predict the minimum value of terminal capacitance required for excitation as well as for maintaining a constant terminal voltage. Comparison of the predicted and the experimental results shows a good agreement.
