ENEX12001 - Electrical Power and Machines

General Information

Unit Synopsis

In this unit you will model basic power system components and electrical machines using simplified linear equivalent circuits. You will explain the relationship between power and energy, and calculate power and energy in power networks and electrical machines. You will apply problem-solving techniques in the analysis of balanced three-phase power circuits using per-unit methodology. You will also investigate and compare the construction and operational characteristics of direct current (DC) and alternating current (AC) electrical machines. You will explain different drive system topologies for the electrical machines. You will explain electrical machine protection and control schemes. In this unit, you must complete compulsory practical activities. Refer to the Engineering Undergraduate Course Moodle site for proposed dates.

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 20%
2. Online Quiz(zes) 25%
3. Practical and Written Assessment 25%
4. Take Home Exam 30%

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%).
