 Generator implementation: Infinite/Non infinite bus generator parameter introduction, simulation.
 Voltage Divider/ Transmission Line Impedances: Representation of Transmission line impedance by
circuit parameters (Series impedance and shunt admittance), implementation of a voltage divider circuit
for load voltage calculation.
 Transformer Operation/Implementation: Principle of transformer operation overview, application in
power systems and implementation for transmission purposes.
 Circuit Breaker operation , Load variation: Circuit breaker simulation parameters, Usage for load
variation, switching effects on the system.
 Load Impedances, Induction Motors: SQC100 Double cage motor analysis and simulation parameters.
Equivalent impedance circuit, Transient and steady state comparison.
 Per Unit Systems, Simulation-Calculation Methods: Simulation of a Radial system having three
different voltage levels, Result comparison with Mathematical analysis.
 Load Flows: Y-bus matrix formulation , Gauss Seidel load flow method used for verification
Teaching Methodology:
Students are taught the course through lectures (3 hours per week) in computer rooms, by
2
means of traditional tools and computer demonstration.
The lecturer introduces the computer simulation software through illustrations in the class room
and the students using the knowledge gained, having the assistance of the lecturer familiarise
themselves with the software.
Furthermore as this subject combines knowledge from many areas of power systems, an
introduction of the subject of each simulation report is given.
Exercises, of contents explained during prerequisite lectures, are mathematically solved and
simulated by the students to form their assessment reports.
Literature search is encouraged by assigning students to identify a specific problem solution,
gather relevant scientific information about how others have addressed various issues and
report this information in writing in their reports.
Students are assessed continuously and their knowledge is tested throughout the duration of the
course. Students are prepared for the final exam, by revision on the subject taught, problem
solving and concept testing and are also trained to be able to deal with time constraints.
The final assessment of the students is formative and is assured to comply with the subject’s
expected learning outcomes and the quality of the course.
