Stability limits of a three-phase induction generator supplying single-phase loads

Abstract

This paper analyzes the stability limits of an autonomous three-phase induction generator supplying singlephase loads. By using a particular balancing algorithm, varying resistive and resistive-inductive loads are successfully supplied up to a threshold of 85% from the generator power in three-phase mode. As the load active power is increased beyond this limit, the voltage tends to decrease. Experiments are carried out in order to establish the overall system behavior when loaded to full load. They show that it is possible to supply the loads beyond the 85% limit.
