Application of Novel Six-phase Doubly fed induction generator for Open Phases through Modeling and Simulation

ABSTRACT

The main contribution of this paper is inspired by the question “Can six-phase doubly-fed induction generator (6-Φ-DFIG) work in unhealthy (with one or more phases open-circuited) conditions or not?”. The conventional DFIG cannot work under open-phase conditions, while the novel 6-Φ-DFIG can operate with one or more phases open-circuited. This paper addresses the mathematical and simulation-based modelling of the novel 6-Φ-DFIG operation under open-phase faults. Moreover, the advantages of the novel 6-Φ-DFIG are also illustrated in this paper. Simulation results validate the mathematical modelling of the novel 6-Φ-DFIG due to an open phase for the post-fault conditions. To the best of the authors’ knowledge, the proposed novel 6-Φ-DFIG has never been modelled and simulated for open-phase conditions anywhere in the world.
