Course content

The subject provides knowledge of electrical energy systems in general, and electrical ship systems in particular. Challenges with the integration of various electrical components and how these can affect each other will be described.

Electrical energy systems will be analyzed and assessed to identify possible unwanted system effects. Methods to reduce the risk of errors and wear and tear will be studied.

An introduction will also be given to symptoms of hidden faults in electrical energy systems, such as e.g. corrosion, vibrations etc., and what consequences this may have over time.

The subject deals with a stand-alone energy system, i.e. microgrid. Practical examples will be taken from industry and shipping.

The theme of the course is:

Electrical energy system in general

Electric ship system

Microgrid

Integration between different electrical components

Unfortunate system effects, analysis and mitigation measures

Monitoring, detection and deviation management

Vibrations

Corrosion

Fatigue

The student must understand:

• Expand modeling and analysis of a selection of circuits, and basic techniques for controlling electrical circuits.
• Application of the circuit concept to other physical domains.
• Safety in the lab, physical circuit connections and troubleshooting, as well as precision and limitations in measuring instruments.

The student must be able to:

• Use network theorems, component characteristics and fundamental laws in electrical circuit theory to calculate parameters in systems with a selection of components.
• Calculate current, voltage and power in single- phase and three-phase circuits under stationary sinusoidal conditions; In the time domain and the frequency domain.
• Carry out system analyzes using hand calculations and simulations, as well as practical connection and measurement in the lab.
• Connect simple circuits according to given specifications. Measure electrical values using a multimeter and oscilloscope.
• Dimensioning/designing a selection of circuits.
• Carry out and report group work/laboratory work in technical reports.

After completing the course, the candidate has the general competence to:

1. Use basic laws and analysis methods from this subject in later parts of the candidate's studies and in work situations.
2. Know Norwegian and English technical terms for methods/techniques, components/ parameters , measuring units etc.
3. Use a simulation tool for the analysis of simple energy systems.
4. Follow safety instructions for laboratory work.
5. Report laboratory work.
