ENEE13016 - Power System Protection

General Information

Unit Synopsis

In this unit, you will analyse and design devices and schemes to protect electrical power apparatus and systems. You will explain the philosophy, principles, concepts and practices, the codes, standards and refer to manuals that guide the design and operation of protection schemes. You will also analyse protection schemes, solve protection problems and correct faults. You will identify requirements, analyse and design protection for power system networks and for apparatus in electrical power systems. You will develop fluency in the technical language of power systems protection and develop the professional skills needed to communicate, learn and work alone and collaboratively to solve problems and document the solution process.

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 30%
2. Online Quiz(zes) 30%
3. Take Home Exam 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: Moodle
More diverse problems in tutorials to get a better understanding of the settings and calculations of relays in various situations.
The tutorial question set will be expanded every year.
Action Taken
The tutorial set was expanded last year.
Source: Moodle
It would be good if the ANSI device number is introduced beside each protection method, such as REF and SEF. This will give more clarity to what the numbers represent. If a relay device is introduce for each topic, it will also help with the assignment and the understanding of how each protection scheme work.
ANSI numbers will be added to the tutorial questions and solutions.
Action Taken

Assessment requirements should be better explained.
The assignment feedback sessions will be brought forward by one week. The assignment group formation process will be accelerated and will be complete in week 2. An indicative assessment rubric will be supplied with the major assignment.
Action Taken
The timings were adjusted and feedback opportunities were pushed this term. The last page of the assignment list the key deliverables and the marking is done against these.
Source: Moodle
It is a unit very rich in content but not too overwhelming difficult in terms of difficulty. The course is well structured and easy to follow.
Continue as is.
Action Taken
Continue as is.

Only the lack of face to face interaction and missing substation visit but that was out of our control this year.
The substation visit will be introduced, health directives permitting.

Unit learning Outcomes

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

  1. Analyse and design power system protection schemes to solve operational problems and correct faults
  2. Apply codes, standards, guidelines in manuals to design power system protection schemes for given operational scenarios
  3. Design protection schemes for power networks, including determining the type and nature of suitable protection for apparatus that needs protection
  4. Document solutions effectively using electrical power systems protection terminology, symbols and diagrams to present the information in a professional manner
  5. Communicate, work and learn both individually and in teams, in a professional manner.
