Double Fed Induction Machine for Electrical Naval Propulsion

This paper deals with the modeling of a Doubly Fed Induction Machine (DFIM) used in Electrical Naval Propulsion. The advantages of the proposed architecture are described and exploited in order to guarantee improved power efficiency of this propulsion system. Two control strategies, the Stator Field Oriented Control (SFOC) and Dual Direct Torque Control are proposed. The load torque propeller model is developed and the Saber simulation results of all systems are presented and discussed. The methodology called “pseudo experimentation” is used to validate the performances of the system.
