Overview

This core course in the ADNG and BENS programs introduces concepts and practices essential for the comprehension of higher level courses in the allied electrical power load flow, stability and fault analysis fields.

This course introduces the principles and practical aspects of generation, transmission distribution and control of electrical energy. On successful completion of this course, the student should be able to discuss the technical, environmental and economic considerations of planning and operating different types of electrical plant (generators, transformers, circuit breakers, cables, insulators and transmission lines), as well as principles of substation layout, control, instrumentation and protection. The student should also be aware of the theoretical principles of system stability, load flow, and fault analysis of power systems using computing software tools.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. justify the typical structure of modern electricity supply systems on the basis of economics, reliability, safety and technical constraints;
  2. compare underground cables against overhead lines on the basis of environmental impact, cost, technical performance and supply reliability;
  3. analyse three-phase electrical networks under abnormal conditions;
  4. determine, by qualitative analysis, the performance requirements of electricity supply system practical hardware;
  5. analyse the impact of transformer tap-change on the voltage profile of radial feeders;
  6. compare the relative strengths and weaknesses of typical protection schemes.

Text and materials required to be purchased or accessed

Ramakrishnan, G 1994, Electricity supply systems examples using Mathcad, ISEE Trust, Toowoomba.
(Very useful for doing the set assignments - available as a PDF on the StudyDesk or as a soft cover available from the USQ Bookshop.)
A scientific calculator. Matlab, a word processor, Excel and Simscape Electrical will be needed for the assignments. Instructions on how to download and install Matlab and Simscape Electrical will be provided on StudyDesk.
In this course, the study book, the introductory book and the set text (Ramakrishnan) serve as the main source of all assessable information — sufficient for students to meet all the course objectives to a high level of achievement without recourse to the recommended reference materials..

Student workload expectations

To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
