A transient stability tool combining the SIME method with MATLAB and SIMULINK

This paper proposes an efficient educational tool for evaluating the transient stability of
multi-machine electric power systems with possible future extensions to control (stabilisation). It uses
the Single Machine Equivalent (SIME) transient stability method combined with SIMULINK to model
transient stability phenomena, and the GUIDE (Graphical User Interface Design Environment) software
of MATLAB. The resulting package validates the data and simulates the results by executing the
SIMULINK model in the background in a user-transparent manner. It also provides the user with an
extremely flexible tool, which enables him or her to enter, modify, and/or add on complexity to the
existing model, thanks to the powerful hierarchical structure of SIMULINK. Considering the popularity
and availability of MATLAB at the university level, this package should prove useful for pedagogical and
research purposes, while at the same time having the look and feel of commercial packages.
