Abstract The transient and steady-state models of slip energy recovery drive (SERD) are obtained in synchronously rotating reference frame in [P.C. Krause, O.Wasynczuk, M.S. Hildebrandt, Reference frame analysis of a slip energy recovery system, IEEE Trans. Energy Convers. 3 (2) (1988) 404–408; E. Akpinar, R.E. Trahan, A.D. Nguyen, Modeling and analysis of closed-loop slip energy recovery induction motor drive using a Linerizatio technique, IEEE Trans. Energy Convers. 8 (4) (1993) 688–697; S.A. Papathanassiou, M.P.

Ince, Modelling and output power optimization of a wind turbine driven double output induction generator, IEE Proc. Electr. Power Appl. 141 (2) (1994) 33–38]. The steady-state solution is provided in [P.C. Krause, O.Wasynczuk, M.S. Hildebrandt, Reference frame analysis of a slip energy recovery system, IEEE Trans. Energy Convers. 3 (2) (1988) 404–408; M.Y. Uctug, I. Eskadarzadeh, H. Ince, Modelling and output power optimization of a wind turbine driven double output induction generator, IEE Proc. Electr. Power Appl. 141 (2) (1994) 33–38]. A fourth and fifth order transient models are obtained in [E. Akpinar, R.E. Trahan, A.D. Nguyen, Modeling and analysis of closed-loop slip energy recovery induction motor drive using a Linerizatio technique, IEEE Trans. Energy Convers. 8 (4) (1993) 688–697; S.A. Papathanassiou, M.P. Papadopoulos, State-space modeling and eigenvalue analysis of slip energy recovery drive, IEE Proc. Electr. Power Appl. 144 (1) (1997) 27–36], respectively. These models can be used to predict the performance, when the effect of overlap angle and rectifier input current harmonics are ignored, and the rectifier input power factor is also assumed to be unity. In this paper, both models are solved in Matlab and results are compared to the results of Simulink model of the SERD.
