ABSTRACT
This chapter discusses the propulsion system of an icebreaking ship, called a multipower source traction drive, with four diesel generators was analyzed. The system consists of a diesel-generator subsystem, a main switchboard, an electric energy converter, and an electric motor. The typical operational modes of arctic cargo ships are as follows: As an alternative to the conventional 3-phase traction electric motor, a multiphase traction motor with 6-, 9-, and 12-phases is considered, the detailed description and features of which are presented. The results of the calculation allow concluding about the impact of the phase number of the traction electric motor on the reliability and fault tolerance indices of the entire propulsion system. The main function of such systems is to achieve the required level of sustainable and safety operations with maximum efficient and stable fulfillment. The implementation of the specified requirements is closely related to the assessment of sustainable operation indicators of the system.
