Abstract :
In the paper, we model the integrated power system (IPS) of a typical destroyer ship coupled to hydrodynamics. This IPS is composed of a 21 MW, 3-phase synchronous generator supplying electric power to 4160 V AC bus and to a 19 MW, 15-phase induction motor driven by an indirect rotor field oriented control for the motor torque. Moreover, stochastic responses are examined when there exists a variation in the induction motorpsilas rotor resistance and a disturbance from the slowly-varying added resistance, derived from a Pierson and Moskowitz sea spectrum.
