Marine Propulsion Module 4: Electrical Drive Characteristics

The training series Marine Propulsion Systems is a unique technical and international oriented training for those who wish to acquire in-depth knowledge of the design of different marine propulsion systems. Topics during the five modules range from different power plant concepts and components to integrating components into properly matched propulsion systems. Working principles and characteristics of propulsors, internal combustion engines and electric power generation and distribution systems will all be dealt with throughout the training series. The series concludes with a module on matching engines with propulsors including off-design operation of propulsion systems.

The fourth module ‘Electrical Drive Characteristics’ will provide the participants with a thorough understanding of the working principles of electrical power generation and distribution systems.

Objective

During this module the participants will learn about electric power systems and their main design aspects. The difference in electrical machines (such as AC and DC) will be explained, their working principles, as well as their components and several mechanical issues in the design and installation. The relation between machines, components, operating conditions and electrical propulsion concepts will be described and illustrated by means of real examples installed on board of vessels. Safety measures in design, installation and use of the electrical drive systems are an important topic and will be mentioned throughout the course. Knowledge of basic physical and electrical principles and theory required to understand the working principles of electrical propulsion systems will be explained by the teacher. The theory is practised by means of exercises during the module. At the end of this module the participant will be able to decide which type of electrical drive component and/or system will be suited best for a particular vessel design.

Topics

  • Introduction to electrical propulsion systems and their components
  • Electrical propulsion: design aspects, reasons for choosing electric propulsion (safety, noise and vibrations), propulsion concepts, installation, environmental aspects, operating conditions

  • Mechanical design aspects electric machines: bearings, temperature rise, cooling methods, protection of systems
  • Dynamic positioning: design aspects for different propulsion concepts, (redundant) power and distribution, integrated automation system, vessel management and control, lay-out systems
  • Standards for electrical propulsion
  • Electrical components and their physical working principles: resistor, inductor, capacitor, diode, thyristor, transistor, rectifier, chopper
  • Characteristics and types of inverters, converters and transformers
  • Theory of electric power: Kirchoff’s first and second law, vector representation, complex calculations, 3-phase systems
  • EMC: Electromagnetic Compatibility, Electromagnetic Emission and Immunity
  • Electromagnetic fields, forces and inductions, incl. Faraday’s Law, Lenz’s Law, Lorentz’s Law
  • Harmonic distortion and short circuit calculations
  • High voltage installations: physical characteristics, safety, design high voltage switchboards
  • Fuel cells: working principle, fuel cell types, installation
  • Superconductive machines
  • History and development of electric propulsion systems

Target group

This module is intended for designers and (sales) engineers who deal with the integration or the design of marine propulsion systems and in particular electrical propulsion during concept design phase. It will also be of interest to people who come across aspects of these systems during their (daily) work and who wish to learn more about the working principle of marine electrical propulsion systems. The international setting offers participants a unique opportunity to gain knowledge and to network with colleagues, clients and suppliers. This enables them to position their companies even better in the international shipbuilding cluster.

Course material

The participants will receive a binder with the lecture slides.
