ELECTENG 731 : Power Systems

Engineering

2024 Semester One (1243) (15 POINTS)

Course Prescription

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. Load flow, fault, stability and power quality. Supplemented by laboratories where students learn to use professional software to implement the theoretical aspects.

Course Overview

This course is an introduction to fundamental aspects of power systems theory and analysis. It includes review of the modeling of
components of an integrated power system. This is followed by analysis of power systems, which provides the foundation of
understanding how modern power systems work. The analysis part includes network analysis concepts and techniques for load ow,
fault, stability studies, market analysis.

1. Power Systems Fundamentals & Load Flow Analysis 
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.
2. Fault Analysis 
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.
3. Power Systems Transient Stability Analysis 
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.
4. Power Systems Modeling, Pricing and Optimization 
DC load flow models; Review of Linear Programming; Electricity Markets; Locational Marginal Pricing (LMP); New Zealand Electricity market & NZ Scheduling Pricing & Dispatch (SPD) model; Financial transmission Rights (FTR); Emerging Market Mechanisms for addressing Scarcity and Demand Side Participation; Mixed Ownership Model (MoM) for Generation.

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect 36 hours of lectures; 24 hours for laboratories, assignment; 50 hours of reading and thinking about the content and 40 hours of work on assignment, test, exam preparation.

Delivery Mode

Campus Experience

Attendance is required at scheduled activities including labs to receive credit for components of the course.
Lectures will be available as recordings. Other learning activities including labs will not be available as recordings.
The course will not include live online events including group discussions/tutorials.
The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Health & Safety

  • Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy.
  • Standard health & safety regulations in the power systems lab will need to be followed at all time.
  • Students are expected to adhere to the guidelines outlined in the Health and Safety section of the Engineering Undergraduate Handbook.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

Course structure will be kept more or less same, lecturing orders might be adjusted.

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 their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
