Requisites

Pre-requisite: ELE1801 or Students must be enrolled in one of the following Programs: MEPR or GCEN or METC or GEPR

Other requisites

Recommended prior or concurrent study: ELE3803 or ELE2702.

Rationale

This core course in the ADNG and BENS programs introduces concepts and practices essential for the comprehension of higher level courses in the allied electrical power load flow, stability and fault analysis fields.

Synopsis

This course introduces the principles and practical aspects of generation, transmission distribution and control of electrical energy. On successful completion of this course, the student should be able to discuss the technical, environmental and economic considerations of planning and operating different types of electrical plant (generators, transformers, circuit breakers, cables, insulators and transmission lines), as well as principles of substation layout, control, instrumentation and protection. The student should also be aware of the theoretical principles of system stability, load flow, and fault analysis of power systems using computing software tools.

Objectives

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. justify the typical structure of modern electricity supply systems on the basis of economics, reliability, safety and technical constraints;
  2. compare underground cables against overhead lines on the basis of environmental impact, cost, technical performance and supply reliability;
  3. analyse three-phase electrical networks under abnormal conditions;
  4. determine, by qualitative analysis, the performance requirements of electricity supply system practical hardware;
  5. analyse the impact of transformer tap-change on the voltage profile of radial feeders;
  6. compare the relative strengths and weaknesses of typical protection schemes.

Notes
  1. This will be an open examination. Students will be provided further instruction regarding the exam by their course examiner via 精东传媒appDesk. The examination date will be available via UConnect when the official Alternate Assessment Schedule has been released.

Important assessment information

  1. Attendance requirements:
    It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    Due to COVID-19 the requirements for S2 2020 are:
    To satisfactorily complete an individual assessment item a student must achieve at least 50% of the marks for that item.

    Requirements after S2 2020:
    To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    Due to COVID-19 the requirements for S2 2020 are:
    To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course.

    Requirements after S2 2020:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the marks available for that assessment item.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure (point 4.4.2).

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.

  6. Examination information:
    Due to COVID-19 the requirements for S2 2020 are:
    An Open Examination is one in which candidates may have access to any printed or written material and a calculator during the examination.
