Electrical Power System Modeling and Simulation of Putrajaya Precinct 5 Gas District Cooling Plant

As a prerequisite for FYP, the author is required to submit a dissertation that records on
going study of electrical power system in a Gas District Cooling (GDC) Plant located in
Putrajaya Precinct 5, which subsequently is simulated to explore the system behaviour
and response. Two major approaches of power system analysis, which has been covered,
are load flow and short circuit studies. In relation with the operation of the plant, it is
necessary to conduct such studies to ensure system's stability and robustness.
The robustness of a power system is measured by the ability of the system to operate in a
state of equilibrium under normal and perturbed conditions. Power system stability deals
with the study of power system's behaviour under conditions such as sudden changes in
load or short circuits on buses or branches.
The first section of this report will elaborate on the introductory part, which consists of
the brief description on the project, the scope of work and also the main activities that the
author has participated.
The second part of the report will cover the details of the literature review that the author
has undergone. The first study being carried out is the process requirements, which
encompass mechanical principles of the GDC system that is very important in designing
Electrical Load Analysis (ELA). ELA is then evaluated to calculate maximum demand
and peak load. Equipment sizing, power flow study using Newton-Raphson method and
short circuit study using Per Unit method based on comprehensive study has also been
conducted.
The third section will focus on the methodology that has been taken by the author
throughout her final year period in UTP. Consequently, this section will highlight
procedures and tools that have been utilized in
SKM® Power Tools [4]. SKM® Power Tools [4] have been extensively used in industry
as it usually has the simplest solution for most cases. The aim of this project is to
understand how the system works by creating a software simulation that represents
electrical power utilization. Prior to this, there is a need in understanding an electrical
system response with presence of a disturbance and interruption.
This next slot represents results and discussion that has been covered especially on short
circuit and load flow studies. The main intention is to develop a model for load flow and
short circuit studies to validate the accuracybased on the relevant data obtained from the
plant.
The last section will outline some recommendations and will represent as conclusion of
the report. This chapter is focusing on the relevancy of this study and the achievement of
this project according to the objective and mil
