Power Systems 2 ENG431


Calculation of unbalanced fault conditions, methods of symmetrical components, the admittance model and network calculations, the impedance model and network calculations, Thévenin's theorem, load flow solutions, the Gauss-Seidel method, the Newton-Raphson method, power flow studies in system design and operation, SKM Power Tools application for load flow analysis, fault calculation using the bus impedance matrix, the equal-area criterion for transient stability analysis, economic operation of power systems, unit commitment, state estimation of power systems, reliability analysis of power systems. The aim of this course is to instill confidence and understanding of those concepts of power system analysis that are likely to be encountered in the study and practice of electrical power engineering.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

Special approval is required for enrolment into TNE Program units.

TNE Program units special approval requirements.

* The Final WW Date is the final date from which you can withdraw from the unit without academic penalty, however you will still incur a financial liability (see withdrawal dates explained for more information).

Unit census dates currently displaying for 2020 are indicative and subject to change. Finalised census dates for 2020 will be available from the 1st October 2019.
