Synopsis

This module aims at utilising the knowledge that the students obtained in Electrical Circuits fundamentals of the second year module to provide them with in-depth understanding of power system transmission and distribution. This range from voltage transformation by the power transformers to overhead line design and eventual distribution to the point of usage like motors and lights. The safe distribution of electrical power is made possible by protective relays that are set up to isolate the faults without interrupting the supply to other functional areas of the reticulation network. Therefore fault calculation and discrimination setting are an important part of power system protection.

Outcomes

On completion of the module, students will be expected to be able to:

1

Describe the principles of Power transmission

2

Design power transmission lines

3

Explain the concept of power system stability

4

Interpret the functioning of voltage and current transformers

5

Perform Fault calculations

6

Describe the characteristics of protective relays

7

Apply principles of electrical power system protection

Assessment

Coursework assessment: 45%
Examination: 55%

Workload requirements

Power systems engineering is about the reliable and safe supply of electrical power to drive the mechanical engineering systems. It is therefore essential that mechanical engineers are conversant with the power system fundamentals and application. There will be a combination of lectures, that will include interactive elements, assignment will be done in a group and experimental work to be done in a laboratory. All outcomes will be assessed by means of assignments, laboratory work, class tests and a final examination.
