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

... rm 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.
