“Power system is dynamic in nature and it is constantly subjected to disturbances and unpredictable faults. It's main objective that these disturbances and faults do not lead the system to unstable condition. Power system stabilizers (PSS) are used to improve the damping during low frequency oscillation and other faults under these disturbances. PSS are designed by conventional and non-conventional controllers. Conventional controller’s uses phase lead compensation techniques, but they cannot provide best performance in all loading condition. To cover wide range of conditions non-conventional controllers used such as Fuzzy Logic controller. This paper presents the study about PSS using Fuzzy Logic to enhance stability of single machine infinite bus system. The input of synchronous machine are Speed deviation and acceleration. The supplementary voltage signals are taken from fuzzy logic controller are given to excitation system of the synchronous machine. Results presented in this paper shows that fuzzy logic based PSS design gives much more better performance than conventional PSS.
