ENEE13016 - Power System Protection
Term 1 - 2017


All details in this unit profile for ENEE13016 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student). The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.

Overview

Students analyse and design devices and schemes to protect electrical power apparatus and systems. They explain the philosophy, principles, concepts and practices, the codes, standards and manuals that guide design and operation of protection schemes They analyse protection schemes, solve protection problems and correct faults. Students identify requirements, analyse and design protection for power system networks and for apparatus in electrical power systems. They develop fluency in the technical language of power systems protection and develop professional skills needed to communicate, learn and work alone and collaboratively to solve problems and document the solution process. Distance education (FLEX) students are required to have access to a computer and make frequent use of the Internet.

Assessment Overview

Assessment Task Weighting
1. Written Assessment 30%
2. Online Quiz(zes) 30%
3. Written Assessment Pass/Fail
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%). Consult the University’s Grades and Results Procedures for more details of interim results and final grades.

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.

Feedback Source Recommendation
The best part was the broad range of protection functions covered in the course Course Experience Questionnaire The course is continually updated to cover the key industrial applications
The design assignment needs some course content throughout the term. This project should be more structured like a PBL subject, which does workshops throughout the term, demonstrating some fundamental design practices and calculations. Course Experience Questionnaire Some assignment workshop activity will be added into the tutorial time.
NPAG protection guide is really good source, but sometimes it is too complex. Learning guide is a really valuable source. Course Experience Questionnaire The Network Protection and Automation Guide is a key industry resource and it very complete. Unfortunately the document is huge. The weekly lecturers will be upgraded to give more guidance on using the NPAG.
On successful completion of this unit, you will be able to:
  1. Describe and explain the philosophy, principles, concepts and practices that are the foundation of electric power systems protection [2, 3, 5, 7, 8, 9]
  2. Identify, explain the scope and standing of, and apply codes, standards and manuals used to guide design and operation of electric power systems protection [2, 3, 10]
  3. Analyse power protection systems, modify and design such systems to solve problems and correct faults [3, 4, 5]
  4. Describe devices and schemes used to provide protection in power systems, explain their operation and design protection devices and schemes to operate in given situations [1, 2, 3, 4, 5]
  5. Identify apparatus that require protection in power systems, explain the nature of the protection they required and design protection schemes for these apparatus [1, 2, 3, 4, 5]
  6. Describe the types of protection required in power systems networks, explain the nature of the protection required and design protection schemes for these networks [1, 2, 3, 4, 5]
  7. Communicate effectively using electrical power systems protection terminology, symbols and diagrams [1, 2, 3]
  8. Work and learn autonomously and collaboratively to solve problems, record and communicate clearly and professionally the approach used to solve problems and the reasons for adopting such approaches to the problem [2, 6, 9, 10]

Assessment Criteria

The Simplified Protection Diagram

It is acceptable to hand draw the diagram (CAD can take time). The diagram should show clearly:

The primary plant – transformers, breakers and busbars

  • The CT and VT locations
  • The protection relays with a single line connection to their inputs (generally CTs and VTs) and outputs (circuit breaker operating coils). Show the IEEE device numbers on the relays.

To achieve clarity of presentation the simplified drawing can omit:

Interconnections between the relays;

  • The relay tables;
  • Details of the housekeeping power supplies.

Design Summary

The design summary would be expected to refer to the protection diagram. It should:

  1. Identify the protection zones;
  2. For each protection zone specify:
    1. The protection schemes to be applied;
    2. How backup protection is achieved;
    3. The placement of CTs and VTs;
    4. Provide the basic ratings for CTs and VTs;
    5. For overcurrent protection schemes only, give suitable relay settings.

Main Body

Provide an overview of the protection zones and protection schemes;

  1. For each protection zone your plan will specify:
    1. Provide a brief rationale for the selection of the scheme(s);
    2. Provide a brief rationale the placement of CTs and VTs;
    3. Outline the calculations for the ratings of CTs and VTs;
    4. Outline the calculations for overcurrent relay settings;
    5. Provide recommendations for suitable commercial relays.
  1. For each protection zone, give at least two examples of how the protection system will safely and reliably detect and isolate faults within the protection zone. One fault will be a earth fault, one fault will be a line to line fault;
  2. For each protection zone, give at least one example of how the protection system will discriminate against a fault outside of the protection zone.

This is an individual assignment.
