Unit Outline

The aim of this unit is to instill confidence and understanding of those concepts of power system analysis that are likely to be encountered in the study and practice of electrical power engineering. The approach is to develop the thinking process of the student in reaching a sound understanding of a broad range of topics in the power-system area of electrical engineering. Calculation of unbalanced fault conditions, methods of symmetrical components, the admittance model and network calculations, the impedance model and network calculations, Thévenin's theorem, load flow solutions, the Gauss-Seidel method, the Newton-Raphson method, power flow studies in system design and operation, SKM Power Tools application for load flow analysis, fault calculation using the bus impedance matrix, the equal-area criterion for transient stability analysis, economic operation of power systems, unit commitment, state estimation of power systems, reliability analysis of power systems.

Intended Learning Outcomes

As per the Assessment and Results Policy 1.3, your results will reflect your achievement against specified learning outcomes.

On completion of this unit, you will be able to:


1.	Analyse unbalanced short-circuit and open-circuit conditions.
2.	Perform load-flow analysis using admittance and impedance models of power systems.
3.	Perform power security and reliability analysis of power systems.
4.	Design, analyse and evaluate power systems using professional electrical engineering software.
5.	Communicate results of power system analysis through report writing and oral presentations.

Assessment Task 4: Project

Task Description:

The project provides students an opportunity to apply their knowledge and skills acquired throughout this unit to the design, simulation and analysis of a given power system. The task will involve applying the learnt software packages, analysis techniques and key knowledge regarding the components of a power system. The project includes an individual report (70% of the project examination) and a joint oral presentation (30% of the project examination).

Task Length:

Typically 30-40 page report and 15 min presentation + questions.

How your final result is determined

To pass this unit, you need to demonstrate your attainment of each of the Intended Learning Outcomes, achieve a final unit grade of 50% or greater, and pass any hurdle tasks.

Submission of assignments

Where practicable, assignments should be submitted to an assignment submission folder in MYLO. You must submit assignments by the due date or receive a penalty (unless an extension of time has been approved by the Unit Coordinator). Students submitting any assignment in hard copy, or because of a practicum finalisation, must attach a student cover sheet and signed declaration for the submission to be accepted for marking.

Academic integrity

Academic integrity is about acting responsibly, honestly, ethically, and collegially when using, producing, and communicating information with other students and staff members.

In written work, you must correctly reference the work of others to maintain academic integrity. To find out the referencing style for this unit, see the assessment information in the MyLO site, or contact your teaching staff. For more detail about Academic Integrity, see Important Guidelines & Support.

Requests for extensions

If you are unable to submit an assessment task by the due date, you should apply for an extension.

A request for an extension should first be discussed with your Unit Coordinator or teaching support team where possible. A request for an extension must be submitted by the assessment due date, except where you can provide evidence it was not possible to do so. Typically, an application for an extension will be supported by documentary evidence: however, where it is not possible for you to provide evidence please contact your Unit Coordinator.

The Unit Coordinator must notify you of the outcome of an extension request within 3 working days of receiving the request.

Late penalties

Assignments submitted after the deadline will receive a late penalty of 5% of the original available mark for each calendar day (or part day) that the assignment is late. Late submissions will not be accepted more than 10 calendar days after the due date, or after assignments have been returned to other students on a scheduled date, whichever occurs first. Further information on Late Penalties can be found on the Assessments and Results Procedure.

Review of results and appeals

You are entitled to ask for a review of the marking and grading of your assessment task if there is an irregularity in the marking standards or an error in the process for determining the outcome of an assessment. Details on how to request a review of a mark for an assignment are outlined in the Review and Appeal of Academic Decisions Procedure.
