Sample subject outline - Semester 2 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Use of standards for the earthing of electrical equipment is common practice in industry and you need to be able to use the standards to perform selection and design. This unit also addresses the communication systems and protocols to implement into power systems. Having completed units that provided the theoretical background, this unit is designed to provide a link to important areas for employment on graduation. Thus, the unit is placed as a specialised unit in the second major in Power and Energy Systems.
Aims
The unit is aimed at providing you with an overview of earthing requirements for power delivery as well as communication systems which ensure safe and reliable operation. The subject aims to provide you some insights into the engineering world including site visits and the design of real systems.
Objectives
On completion of this unit you should be able to:
- Develop designs for cables and switchgear suitable for building services and be able to present to the class.
- Be able to calculate the require cable sizing for given building requirements
- Specify procedures and analyse the results of earthing studies relevant for lines and substations
- Be able to compute the required earthing given ground resistivity and fault levels
Content
The unit is structured with two modules.
Module A. Plant and Equipment
In this module you will carry out aspects of design of electricity supplies to buildings or distribution systems. This will involve specification of equipment such as supply transformers, cables, switchgear, motors and stand-by generators and calculation of voltage drops and fault level studies. Following initial lectures on switchgear and cable properties you will draw knowledge from supplier's catalogues and from Australian Standards. The approach will be to facilitate self-learning to simulate a professional engineering environment. You will need to share information and to facilitate this, and to develop communication skills, you will be required to make presentations on selected aspects of the project.
Module B. Earthing System Principles and Design
The "Earthing System Principles and Design" module is designed for students specialising in the field of Electrical Power Systems. Earthing systems are an electrical safety critical component of any transmission or distribution system. The task of the earthing system designer is to ensure that earthing system enables the correct operation of the power system, protects equipment from damage and guarantees an acceptable level of safety for electrical workers and members of the community.
Approaches to Teaching and Learning
Teaching mode: Hours per week 4
Lecture: 2 hours per week
Tutorials & Computer Lab: 2 hours per week
Lectures will present some basic concepts in earthing and communication design relating to the relevant standards.
Tutorials and computer labs will be used for problem solving exercises related to the use of standards in the selection of earthing and communication systems design.
Assessment tasks are design based with preliminary problem solving exercises in addition to some oral presentation or the approach.
Tutorials and lab classes will encourage self learning in design capability, understanding of systems inspected during visits, practical ability in measurements, and interpretation of standards.
The design problems will be based on a real world scenario that will provide an introduction to what you can expect to experience in a utility after graduation.
Assessment
General Assessment Information
Assessment will be based on three items:
All three assessment tasks will form part of the summative assessment for this unit with the weights for each assessment task as shown below. Criterion Referenced Assessment will be used for summative assessment as requirement of QUT policy.
Assessment name:
Design
Description:
Selection and design of power equipment for a given requirement.
As part of the design, you will solve an individual problem and preset the solution for feedback before proceeding to work in a small group to design and select power equipment for a given requirement. This may include site visits which will form the basis for the assessment task.

Academic Honesty
QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.
A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.
Resource materials
Lecture material (presentations) will be available from the Black Board site for this unit and will mirror some material from the Australian Power Institute site.
Australian Standards and research material from the library and its databases.
Risk assessment statement
You are expected to undertake laboratory work which is the only area that can constitute a risk. In order to minimise this risk you are expected to undertake Health And Safety training and obtain a "green card". Details of this will be provided at the commencement of the semester by the unit co-ordinator.
Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
