Calendar notes
Builds on the knowledge of three-phase power systems components to understand modelling, formulation and typical analysis carried out by electricity transmission, distribution and generation entities. The analysis part includes network analysis concepts and techniques for load flow, fault, and stability studies, supplemented by laboratories where students learn to use professional software to implement the theoretical aspects.
Prerequisite: ELECTENG 309Restriction: ELECTENG 411
Course outline:
(Course details representative only. For various reasons minor additions/deletions may occur)
Power Systems Fundamentals & Load Flow Analysis (AU)
Review of power systems fundamentals & per-unit systems; SCADA, EMS, DMS & Smart Grid; Development of non-linear load flow equations; bus admittance matrix; classification of bus types; solution techniques; voltage and power flow control; general algorithms for the solution of the load flow equations-the Gauss Seidel and Newton Raphson techniques; Approximations of Load Flow.
Fault Analysis (AU)
Types of faults, use of Thevenins and Superposition Theorems for fault analysis; symmetrical faults and fault levels; matrix methods for the analysis of faults in large order systems; asymmetrical fault conditions and the symmetrical components transformation technique for analysis; sequence networks and the application of the connection methods; matrix methods extended to the analysis of asymmetrical faults in larger order systems.
Power Systems Transient Stability Analysis (AU)
Basic concepts of power systems stability; the dynamics of the synchronous machine in the network; the electromechanical equations; coherent machines; a two machine equivalent system and representative swing equations; the swing equation for a single machine on infinite bus-bars; the Equal Area Criterion; critical clearing time and angle calculation.
Coursework
The basis for overall assessment is 50% final examination, 50% on-course assessment which consists of two tests (15% each), two labs (4%) and two assignments (16%).To gain a pass in this course you must obtain a passing mark in the combination of the final examination mark and the on-course assessments.
Test 1 - Friday, 5th April (Closed book, Restricted Calculator)
Test 2 - Friday, 24th May (Closed book, Restricted Calculator)
Assignment 1 - Thursday, 30th May 5 pm (Submission deadline)
Assignment 2 - Friday, 7th June 5 pm (Submission deadline)
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious offence. The work that a student submits for grading must be the student's own work, reflecting his or her learning.
Exam rules
50% weightage will be on final examination (Closed book, Restricted Calculator)
Inclusive learning
Students are urged to discuss privately any impairment-related requirements face-to-face and/or in written form with the course convenor/lecturer and/or tutor.
Other assessment rules
Laboratory:
There will be three lab sessions of 2 hours each. The laboratory sessions involve load flow, fault analysis of a typical power system. The two lab sessions are to facilitate understanding of the lecture material and get a feel for practical power system analysis. Educational version of DigiSilent Powerfactory software will be used for these lab sessions. The professional version of this software is used by system operator (Transpower), distribution companies, consultants etc. in New Zealand.
The lab session is scheduled for 2 hours slots during 4th and 9th teaching weeks. You will need to enroll into a convenient lab slot. Your lab simulations must be seen and marked off by the lab GTA: failing which zero marks will be awarded for this assessed component. Please note that under the departmental rule only one lab re-run will be permitted with payment schedule: see the document Guide to laboratories, available via Canvas.
Academic integrity
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting his or her learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the world-wide web. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.
All students enrolled at the University of Auckland are required to complete a compulsory Academic Integrity course, usually in their first semester/year of enrolment. The University of Auckland’s full guidelines on procedures and penalties for academic dishonesty are available here.
Actions shared/based on previous feedback
Survey from previous years for this course has been consistent and good. In 2019, this course will work towards the same level if not better. Furthermore, the course content has been revised. More real-life experience components have been added
This site intends to guide you through your chosen specialisation at the Faculty of Engineering. The semester links lets you view detailed course information for your chosen course. Please note that the structure displayed for your specialisation here will reflect what’s available over the upcoming semesters, but detailed information may be from a previous year.
