VOLTAGE CONTROL OF PARALLEL OPERATED SELF-EXCITED INDUCTION GENERATORS

This paper describes two methods of analysis to control the common bus voltage of any number of parallel self-exited induction generators, SEIG's, under steady state balanced conditions. The proposed methods are general and can be used for a single or a group of SEIG's employing similar or different machines with equal or unequal prime movers speeds. Theoretical predictions of the two models have been verified experimentally. Using these methods, effects of various parameters on the voltage control characteristics are examined for a number of cases employing similar and different SEIG's at equal and unequal speeds. The results are summarized in the paper.
