Abstract :
This paper explores the operation of doubly fed induction generator (DFIG) under unbalanced supply conditions. Supply unbalance generally has a negative effect on induction machine operation, resulting in increased Joule loss and pulsating torques. The aim of this work is to quantify the effect that stator and/or rotor supply unbalance has on these aspects of DFIG performance.
