Abstract :
The damping of the electromechanical mode oscillation in a multimachine power system is improved by a power system stabiliser (PSS). To prevent the system voltage profile from being deteriorated by the PSS, a static VAr compensator (SVC) with a self-tuning feedback controller is also developed. The effectiveness of the proposed PSS and SVC is demonstrated by computer simulation of the dynamic responses of the system subject to a three-phase fault. It is observed that the combination of PSS and SVC is capable of increasing system damping without deteriorating system voltage profile
