Abstract

This paper presents the performance analysis of power system dynamic stability using Fuzzy logic based PSS for positive and negative value of K₅ constant. Here the two inputs are change in angular speed and rate of change of angular speed whereas output of fuzzy logic controller is a voltage signal. Then the performance of the single machine infinite bus system has been studied without excitation system, with excitation system only, with conventional PSS (lead-lag), and with fuzzy logic based PSS. The simulation results give satisfactory output.
