Course specific prerequisites

Knowledge and skills corresponding to the learning outcomes of the following courses:

SSY033 Basic electric power circuits

Aim

The aim of the course is to give general insights in and knowledge of the electrical equipment that is used in production and maritime industries.

Learning outcomes (after completion of the course the student should be able to)

Examination part A covers the following learning outcomes:

1. Describe an electric power system on a ship during normal operation conditions including the function of individual parts and the operation based on voltage and frequency control.
2. Apply relevant international and national laws and regulations.
3. Calculate cable areas according to the regulations for different cabling in a naval network and select the appropriate overcurrent protection.
4. Describe and model different transformer types as well as calculate voltages, currents, power for loaded transformers.
5. Explain the structure of synchronous and asynchronous machines as well as model the machines in stationary mode.
6. Calculate speed, current, voltage, power and torque at different loads for both synchronous and asynchronous machines, based on their equivalent model.
7. Describe the function and execute parallel operation of synchronous generators in a ship-like power grid at different load conditions.
8. Describe different start and speed control methods for asynchronous motors and calculate starting currents for the different methods.
9. Calculate DC quantities for different rectifiers and frequency converters as well as describe its operation and interaction with electric machines.
10. Calculate short-circuit currents for balanced faults and describe the consequences of short-circuit currents with focus on mechanical and thermal stresses.
11. Describe the principle of an insulation monitoring system.

Examination part B covers the following learning outcomes:
12. Execute a synchronization of a synchronous machine to a three-phase network and explain the functions when generating active and reactive power.
13. Perform fault localization in a ship-like electrical system.
14. Relate to the risks involved in the operation of high voltage equipment
15. Apply regulations for high voltage installations, work environment and safety on board ships and with associated equipment connected on land
16. Describe monitoring and operations of high voltage equipment
17. Describe the working procedure in and in the vicinity of high voltage equipment
18. Describe the principles for grounding of high voltage equipment
19. Describe the risks and damages that may result from improper handling in and in the vicinity to high voltage equipment
20. Describe the risks involved in connecting and disconnecting high voltage equipment
21. Describe the damage that can occur at work in and in the vicinity to high voltage equipment.

Content

Extra Assignments

Examination including compulsory elements

Part A The examination is based on three+three written hand-in assignments and to pass (Grade 3) shall be able to be explained for the examiner or by him/her appointed teacher. For grade 4 the student must be able to discuss the learning outcomes in wider concept but still during normal operating conditions. For grade 5 the student must be able to discuss the learning outcome from a system perspective.

Part B Approved laboratory work with pre/post homework assignments

The final grade is based on part A.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
