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

摘要

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.
