A graphical medium for demonstrating power system stability concepts

Simulation software is a very effective tool for in- class demonstrations and can be readily incorporated in electronic courses. This paper presents an interactive simulation tool to assist instructors for explaining power system stability phenomena. The underlying computational engine is Matlab/Simulaink, whereas the graphical user interface (GUI) is constructed using C#. The GUI provides the capability to modify system parameters/operating conditions interactively. Simulation of a five bus power system model has showed the potentials of the developed tool.
