Overview
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.

Offerings For Term 2 - 2024
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).
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 Overview
Assessment Grading
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%). Consult the University's Grades and Results Policy for more details of interim results and final grades.

- Work individually and collaboratively in a team to produce high-quality outputs.
2 Online Quiz(zes)
The Online Quiz (with several Numerical and Multiple Choice Questions (MCQs)) is generally in the form of problems that require simple calculations to find the correct answer. Students are expected to work individually for this assessment task. To ensure continuous engagement of the students with the learning of this unit, the quiz has been separated to four parts and distributed over first 12 weeks of the term as indicated in the Unit Schedule Section. Each part of the quiz covers the unit content covered in each quarter of the term. Each part of the online quiz opens on the Unit Moodle Website eight clear working days prior to the respective due dates. The online quiz will randomly draw questions from a pre-designed question bank for each individual student. The quiz is a time limited assignment. More details is available for the students through the unit Moodle website. Marks of all four parts of the quiz is added and scaled to a score out of 25 to be added to the unit total.

4 Online Test
The Online Test is an individual assessment task conducted via the Unit Moodle website and during the University examination period. The questions will be available in Moodle during the Online Test time. The test will be Open Book and students can use any printed or electronic material as a reference. The solutions should be handwritten, and scanned during the test time and uploaded to the unit Moodle site before the closing time. The test duration is three hours and a reasonable time would be allowed for uploading the solutions. The Online Test covers all contents of the unit from Week 1 to 12, and from the solutions, the students are required to demonstrate the theoretical knowledge they have gained during this unit. The solutions must be submitted through the Online Test link in Moodle as a single pdf file.
In order to pass, the students must score at least 50% of the allocated marks for the Online Test.
The Online Test is held during examination week. The date and time of the test will be notified later.
Feedback will be available after the grades are confirmed by the school board.
The mark awarded will be based on:
- Accuracy of the method used
- Correct application of mathematics in the calculations
- Correct results
- Compare and explain features of DC and AC electrical machines with regard to their construction and operational characteristics
- Compare and explain features of drive systems, protection and control schemes for electric machines
- Apply appropriate laboratory techniques and software tools to understand power systems and electrical machines
As a CQUniversity student you are expected to act honestly in all aspects of your academic work.
Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.
When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.
Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.
As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.
What is a breach of academic integrity?
A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.
Why is academic integrity important?
A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.
Where can I get assistance?
For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
