MARINE ELECTRIC PROPULSION

Marine Electric Propulsion is a one-week survey course with formal lectures and demonstrations. This survey course provides an introduction to the principles and technologies used in the design and operation of marine electri propulsion drives based on the synchro-converter topology. The course begins with a thorough review of the production and control of three-phase electric power. Power flow is then followed through cables, switchboards, phase-shifting transformers, SCR-based controlled-rectifiers, to the DC-link. Standard six-pulse inverters supplied from the DC-link are then studied, as are synchronous propulsion motors and their excitation systems. For each portion of the system studied, appropriate elements of electric power systems, power electronics, instrumentation, and operational maintenance requirements are discussed. Practical demonstrations are offered to reinforce important fundamental concepts. Additional topics include buck and boost converters, phasor notation, system protection and coordination, transformer vector groups, harmonics, harmonic filters, CTs and VTs, SCR testing, heat-sinks, thermal management, soft-starters, phase control, P-Q-S analysis, and general power system topics.


Course Capacity: 12 students

Prerequisites: Experience with shipboard power plant operation and knowledge of basic electricity and electronics

Special Requirements: This course is typically taken in conjunction with the High Voltage Safety course.
