Abstract

This paper describes a generalized dynamic model of multi-machine power systems for transient stability
analysis and its computer simulation using MATLAB/SIMULINK. The generalized model of the power systems can be
used for teaching the power system transient phenomena, as well as for research works particularly to improve
generator controllers with advanced technologies. Constructional details of various sub-models for the whole power
systems are given and their implementation in SIMULINK environment is outlined. The developed simulation model is
tested on 3-machine 9-bus power system and 10-machine 39-bus New England power system under different large
disturbances. For the studied cases, the critical clearing times (CCT) are calculated and the simulation results are
presented and discussed. Nonlinear time-domain simulation results obtained from several case studies validate the
effectiveness of proposed model for transient stability analysis. The proposed dynamic model has been employed to
support and develop power engineering education at both the undergraduate and graduate levels. Likewise, for
academic and educational use, all component sub-models are transparent and can simply be modified or extended.
