Voltage and frequency control of parallel operated self excited induction generators

Abstract EN

This paper describes a method of analysis to control both the common bus voltage and the frequency of any number of parallel operated self-excited induction generators, SEIG’s, under steady state balanced conditions.

The proposed method is general and can be used for a single or a group of SEIG’s employing similar or different machines with equal or unequal speeds.

Theoretical predictions of the proposed model have been verified experimentally for a number of configurations.

Using this method, effects of various parameters on the voltage and frequency control characteristics are examined for a number of cases employing similar and different SEIG’s at equal and unequal speeds and the results are summarized in the paper.
