Simplified Model to Study the Induction Generator Effect of the Subsynchronous Resonance Phenomenon

2018-01-30, Bizzarri, Federico, Brambilla, Angelo, Milano, Federico

This letter presents a simple model of induction machines able to appraise the induction generator effect of the subsynchronous resonance phenomenon. The proposed model is general and can be applied to induction machines utilized in wind power applications, such as doubly-fed induction generators. A rigorous stability analysis is carried out based on the proposed model. This analysis shows that the induction generator effect leads to a Neimark–Sacker bifurcation.
