Question
Travel and Tourist (T&T) company has been awarded by the government to
transform Pulau Kecik to tourist island. Electrical supply is found a big challenge for
this development. Thus, T&T has hired your company to design a reliable mesh or
loop isolated power system network in the island. The island divided into five areas
namely North, South, West, East and Center area which later can be the bus name.
TABLE Q1 provides the initial design parameters to be adopted.
TABLE Q1
Base MVA
Voltage level
100 MVA
11 kV
Total load
15 MW
Complying with the information given in TABLE Q1, you are given flexibility to
choose relevant and logical parameters to design the network. This flexibility allows
you to decide on the network topology, slack bus voltage, number of generator bus
(PV bus), generator power, generator voltage, number of load bus (PQ bus), load
real power, load reactive power, impedance of the generators and lines/cables.
State all your assumptions where applicable and avoid copying directly from any
sources, you will be penalized for plagiarism in doing so.
a. Using Gauss-Seidel method perform, manual calculation to solve the voltages
at all buses in per unit (up to four decimal places) until FIVE (5) iterations.
b. Using the PowerWorld software and display the snapshot results to compare
with the manual calculation, in part (a), for every iteration. Interpret the result
convergence. Submit the PowerWorld's pwb and pwd files.
C.
Neglecting the load, using Thevenin's equivalent circuit, perform manual
calculation to solve the per unit three-phase balanced fault current and
corresponding bus voltage at all buses (up to four decimal places) for every
faulted bus.
