Abstract
This thesis will describe a newly developed interactive
power system simulator utilising computer-graphics for use
in the teaching of the operation of electrical power system
to the undergraduate power engineering students. The simulator
allows students to study the normal steady state behaviour
of a power system (load-flow analysis) and also the transient
stability of the system due to the different possible
disturbances (dynamic analysis).
In the system dynamics, a general and comprehensive form
of multi-node system dynamic analysis is developed and on
which an extensive simulation facility has been based.
A major part of the author's work has been in the
development of a powerful input/output interface to the dynamic
and load-flow analysis packages, allowing the user to interact
with the program using a graphic display terminal. The
interaction between the user and the computer is then based
on diagramatic terms, plain English options and prompting
messages.
In this thesis, a general method has also been developed
to study the system subjected to simultaneous disturbances.
Different schemes of clearing the fault have also been
investigated, in particular, 3-phase fault and autoreclosure.
The simulator described in this thesis is currently used
as a teaching and design tool at the Electrical Power
Department at the University of New South Wales.
