This report focuses on modelling a balanced three-phase power system using the per-unit system
and validating results through simulations with PSCAD (Power System Computer Aided Design) and
PSS/E (Power System Simulation for Engineers). The system's one-line diagram is analysed, selecting
a common base of 100 MVA and 22 kV at the generator side. Each group is assigned different load
capacities with varying power factors to introduce realistic diversity. The report covers the
identification of the electrical network sections, calculation of base voltage values for each section,
and the determination of per-unit values for components under steady-state conditions. The per-unit
system is employed to simplify calculations and facilitate comparisons of system parameters across
different voltage levels. A simulation study is conducted using PSCAD and PSS/E to verify the
accuracy of the per-unit system results and observe the system's dynamic behaviour. The outcomes
highlight the effectiveness of the per-unit system in analysing complex power systems, while the
simulation results provide validation of the theoretical calculations.

power system for the nominal circuit “π” and determine the sending end line voltage and current
including the percentage of voltage regulation for a medium transmission line model. Each group is
assigned different load capacities with varying power factors to introduce realistic diversity. The
outcomes highlight the behaviour of the system in regulating the voltage and frequency in power
systems, while the simulation results provide validation of the theoretical calculations.
This report investigates generation control and transmission systems, focusing on the analysis of a
power system's steady-state performance. The study emphasizes controlling active and reactive
power to maintain voltage stability and frequency regulation in the power grid, utilizing simulations
conducted in PSCAD (Power System Computer-Aided Design). The system's Single Line Diagram,
which taken from Assignment A, has been modified by adjusting load capacities, generator control

through active and reactive power control of synchronous generators. Additionally, it calculates the
ABCD parameters of the modified power system for the nominal "π" circuit model. Using these

medium transmission line model are determined. Each group in the assignment has been allocated
unique load capacities with varying power factors to simulate realistic system diversity. The

The simulation results will thoroughly be analysed and compared with theoretical calculations
In this assignment, we explored the critical aspects of generation control and transmission systems,
focusing on the steady-state behaviour of a power system. By utilizing PSCAD simulations, we
successfully demonstrated the control of active and reactive power to regulate the voltage and
frequency of the power grid. The modifications made to the Single Line Diagram, including
adjustments to load capacities, generator control methods, and transmission parameters, provided a
comprehensive understanding of system behaviour under various conditions.
The calculated ABCD parameters for the nominal "π" circuit model, along with the derived sendingend voltage, current, and voltage regulation percentage, validated the theoretical principles
governing medium transmission line models. Simulations further reinforced the effectiveness of
synchronous generator controls in managing voltage and frequency fluctuations, ensuring system
stability.
The assignment also underscored the importance of diverse load profiles with varying power factors
in realistic power system analysis. The insights gained from the simulation results and their alignment
with theoretical expectations highlight the critical role of advanced tools like PSCAD in studying and
optimizing power systems. Overall, this task provided a robust foundation in understanding and
addressing the challenges of voltage and frequency regulation in power systems.
