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. Distance students are required to participate in the compulsory Residential School.

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) 20%
3. Practical and Written Assessment 20%
4. Examination 40%

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%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Unit survey
Feedback
The unit-coordinator was extremely helpful, promptly answering any queries.
Recommendation
This good practice will be continued.
Action Taken
The good practice will be continued.
Source: Unit survey
Feedback
Labvolt activity helps students understand the content.
Recommendation
These good practices will be continued.
Action Taken
The good practice will be continued.
Source: Unit survey
Feedback
There is a discontinuity between the first half and second half of the lectures.
Recommendation
This unit will be delivered independently from other electrical units, e.g., ENEE12015 by unit coordinator/lecturer of this unit.
Action Taken
All unit lectures and tutorials were delivered by the unit coordinator/lecturer of this unit in T2 2018.
Source: Unit survey
Feedback
The timing of the tutorials being after the lecture should be reviewed.The tutorial after the lecture didn't seem to work.
Recommendation
Tutorial sessions will be allocated in other days after lecture sessions.
Action Taken
There was a time gap of six hours between lectures and tutorial sessions of this unit in T2 2018.
Source: Unit evaluation
Feedback
Students have appreciated having laboratory exercises follow a step list which make them easy to perform.
Recommendation
This good practice will be continued.
Action Taken
Nil.
Source: In class
Feedback
Students have appreciated using a digital whiteboard, i.e., a digital pen to deliver the tutorials instead of using a document camera.
Recommendation
This good practice will be continued.
Action Taken
Nil.
Source: Unit evaluation
Feedback
Laboratory exercises could not be accessed for several weeks due to a Moodle error.
Recommendation
This happened because of Moodle rollover. In T2 2019, this issue will be checked before the term starts.
Action Taken
Nil.
Source: Unit coordinator
Feedback
Students had a problem with understanding of 3-phase circuits analysis.
Recommendation
The fundamentals of 3-phase circuits will be practised more in this unit.
Action Taken
Nil.
