Abstract: This paper presents a model of a multi-machine system and examines the efficacy of power system stabilisers and static VAR compensator in transient stability enhancement. The main contribution of this work is a compact, user-friendly and comprehensive model to analyse and reinforce the system stability through a coordinated focus on damping of electromechanical oscillations and suppression of voltage deviations. The model is developed by integration of various mathematical equations pertaining to synchronous machines and some network equations. To test the effectiveness of the proposed model, MATLAB-based simulations are carried out by subjecting the system to challenging transients. The performance evaluation of the model incorporating both power system stabilisers and static VAR compensator is tested against the individual performance of each. It is found that the model is effective in maintaining transient stability as well as improving transient stability limits.
