With the development and application of the source of regenerated energy and rapid growth of independent electric power stations, the self- excited power technology of induction generators is attracting more and more attention and has been researched considerably owing to its distinguishing feature. In view of large variation of output voltage of self- excited single phase induction generator, the paper presents an approach of self- regulation of voltage by series capacitor. The operation of self- excited single phase generation of three phase induction generator is analyzed by symmetrical component method, and the fundamental equations and equivalent circuit are derived. Then the formula for calculation of the generator performance and principle of selection of capacitors are given. The experiments of a sample generator verify the validity of the analysis.
