Abstract

This paper introduces a systematic approach incorporating MATLAB and SIMULINK for modeling transient stability of small and large scale multi-machine power systems with their associated controllers. Although there are different commercial and educational packages for power system simulations, this proposed approach introduces a step-by-step simple model starting by modeling a single machine and its controllers as a machine template. This machine template is suitable to be repeated and modified according to the simulated network. A multi-machine model is constructed systematically and easily by cloning the machine template to expand the power system. The regular and systematic expansion from small to larger system emphasizes the flexibility and the simplicity of the proposed approach for modeling different power systems for the purpose of research and educational study. This approach is tested and verified through the comparison of responses of two test systems with respect to their responses from the simulation package of power system toolbox (PST).
