OVERVIEW

The aim of the course is to introduce students to the basic problems related to the operation of the electric generation and propulsion on ships, to guide in understanding the technologies and electrical problems due to the complexity of the ship.

AIMS AND CONTENT

LEARNING OUTCOMES

AIMS AND LEARNING OUTCOMES

The aim of the course is to introduce students to the basic problems related to the operation of the electric generation and propulsion on ships, to guide in understanding the technologies and electrical problems due to the complexity of the ship.

At the end of the course the student will have acquired theoretical knowledge on the electric propulsion and power generation and skills handling practices (in compliance with current safety standards) of basic controller by performing simple ones and the application of analytical techniques for their determination.
Specifically, the student will be able to know the main caracheristic of power generation and electric propulsion and relative controllers.

PREREQUISITES

The knowledge of electrotechnics, automation and basic power systems is acquired and constitutes the necessary foundations for understanding the course topics and taking the tests
exam. It is recommended to follow exams of:

  • 101133 electrotechnics
  • 101131 Shipboard power systems
  • 101126 Automation and control for marine applications

Teaching methods

The course is held with lessons and exercise for an overall amount of 60 hours. Different exercises and laboratory on shipboard power system is foreseen.

The teaching material provided during lectures will be available on AulaWeb.

The laboratory will be held by the teaching teachers, eventually assisted by laboratory tutors. At the beginning of each activity of laboratory a brief theoretical introduction is foreseen in order to provide the basic principles that will be used. In the practical part, the students, divided into groups of two or three and with the support of the teachers and tutors, must apply the experimental protocol provided and the methods described. At the end of each activity, they will have to present a short report with the results obtained from the experimental activity. The organization and the dates of performance laboratory activities will be communicated directly by the teachers at the beginning of the lessons.

SYLLABUS/CONTENT

The course program provides for the presentation and discussion of the following topics:

  • Primary electrical sources and load balance
  • Electric generation and propulsion systems:  definition, problems and specificity of power system control
  • Converters and components for power electronics: electronic components. Type of power converters. Working principles and outline their control techniques.
  • Propulsion drive: type of propulsion engines. Description and issues. Motor start techniques.
  • Distribution systems: possible system solutions for ships with electric propulsion. Analysis of line diagrams and problems of different design concepts.
  • Electrochemical storage: definition, characteristics and system sizing based on electrochemical storage. Hybrid solutions : preliminary design
  • Run electric propulsion systems: central management of electric production, planning aspects of the management of diesel genset.

RECOMMENDED READING/BIBLIOGRAPHY

All slides used during the lectures and other teaching materials will be available on aulaweb. In general, notes taken during the lessons and the material on aulaweb are sufficient for the preparation of the exam.

The books listed below are suggested as supporting texts, but students can still use other texts by University-level, provided they are editions published recently.

EXAMS

Exam description

The exam consists of a written and an oral part.
The work  relates to the topics of the theoretical-practical laboratory: it consists of a software model and home work to be presented one week before the oral exam.
To access the oral test, students must have passed the written test with a minimum score of 18/30 and the mark obtained will be used in the final evaluation by making the average weighted on the number of credits attributed to the two parts. An equal vote or higher than 27/30 in the written test does not affect the possibility of obtaining a final mark of 30/30 after the oral test.
Extraordinary appeals will not be granted outside the periods indicated in the study program regulations, except for out-of-course students.
