Marine Electric Power and Propulsion Systems

At the end of the course, the student should be able:

• define power flow in single- and three-phase AC power systems, as well as DC systems, and generalize the power flow analysis to typical marine electrical power systems, calculate generated/consumed power by electrical machines, and describe the concept of power flow in marine electric distribution systems. 
• explain the principles of operation and control of power electronics converters, and model the system components by equivalent electric circuits, which can be applied to the analysis of marine electrical power systems.
• understand typical electrical propulsion drives, their power electronics controllers, their applications, and the state of the art shipboard power electronics. 
• design an electric distribution and electric propulsion drive for a typical marine vessel based on the specification, operational profile, and class rules. 
• explain the principle of diesel-electric power generation in terms of electric frequency, excitation system, and system voltage; model the speed dynamics of a diesel engine and relate this to the generated electric frequency, and model the generator excitation system. 
• describe the connection of a generator set to a power distribution system; explain the principle of load power sharing between multiple parallel connected generator sets; explain the load profile of the generator sets due to load power changes/possible faults. 
• design a PMS; describe typical PMS topologies; explain main functions offered by PMS; implement, and test some PMS functions in software. 
• understand and explain the main class rules and regulations, including important terms and concepts, applicable for marine electric power plants; explain alternative classification notations; describe relevant methods for verification and testing of different parts of the electric power system. 
• project work: deliver a written project report with a clear and concise presentation of results, analysis, and conclusions; present the results of the project clearly and efficiently. 
• conduct academic studies and written work in an honest and ethical manner, avoiding any kind of plagiarism in work assignment, project reports, and presentations.
