ENAE12007 - Electrical Power Systems

General Information

Unit Synopsis

This course provides students with an introduction to the operation and analysis of electrical power systems. Students explain the features, function and operation of components of power systems and apply key concepts and procedures to analyse routine problems and solve problems involving three-phase power systems. They explain the features, function and operation of transformers, sub-stations, transmission lines and distribution systems and analyse basic transmission line design and operation problems. Students are required to show that they can effectively communicate power systems concepts, professionally document problem and design solutions, and work productively and professionally, both individually and in groups.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 25%
2. Written Assessment 25%
3. Written Assessment 25%
4. Written Assessment 0%
5. Practical and Written Assessment 25%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).
