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.
