Study on Vector Control of the Doubly-fed Induction Motor for Propeller Load Characteristic Simulation

Propeller load characteristic simulation is an important part of electric propulsion system.In this paper,using the characteristics of running in four quadrants and reducing capacity of converters by the rotor side of the doubly fed machine,a doubly fed machine load system is presented to simulate the stable and dynamical properties of marine propeller operating in different conditions.Furthermore,by the vector control strategy of stator field-orient,steady state analyses are performed.The results of simulation show that the doubly fed machine can simulate the propeller torque features perfectly in four quadrants.
