| dc.description.abstract | The bus impedance matrix is an excellent network description use in the solution
of faulty networks. Unlike traditional network analysis, a bus impedance matrix usually
used simplified notation such as a one-line diagram and per-unit system, and focus on
various forms of AC power such as reactive, real, and apparent power rather than
voltage and current. Even though it is easy to use bus impedance matrix for fault
computations, the bus impedance matrix is not easy to form. One difficulty associated to
build the bus impedance matrix is the ordering of primitive elements. There exist a lot of
software implementations of power network studies. The great importance of bus
impedance matrix is analyzing faults of an existing power system network, which also
indirectly planning the future expansion of power systems as well as determining the
best operation of existing systems. The principal information obtained from bus
impedance matrix is the formulation to compute faults of a power system network. This
project is mainly concerned on Kron Reduction method, where the formulations of Kron
Reduction use to develop a program that will reduce the bus impedance matrix back to
its original pxp order in the process of finding a bus impedance formulation. In this
purpose, Visual Basic 6.0 software is used to provide graphic user interface (GUI) for
the user to enter the desired number of buses impedance data at computer. Besides, it
also shows a Zbus matrix and will produce the simplest Zbus matrix at the end of
program calculation. Through the project, it can be concluded that development of bus
impedance matrix using Visual Basic 6.0 can solve impedance matrix up to infinite
buses easily and faster. | en_US |
