Course content
The main objective of the course is to provide the students an understanding of marine electric power systems on ships and offshore platforms, which is of importance for engineering, design, scientific analysis, and management of the marine systems.
The course includes an introduction to electric power systems, with focus on electro-technical concepts and characteristics of electric power systems, 3-phase systems, phasor diagrams, electromagnetic energy conversion.
The course continues with a study of electric machines, power electronics systems and propulsion drives, electric power generation and distribution, power electronics, and energy storage devices and systems for hybrid electric ships. Also, power management systems (PMS, operational issues, and class rules and methods for independent testing and verification is covered in the course.
Learning outcome
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.

Further on evaluation
Portfolio assessment is the basis for the grade in the course. The portfolio includes a written exam (70%) and project works (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
Postponed/repeated exams may be oral.
For a re-take of an examination, all assessments during the course must be re-taken.
