Abstract

This paper presents the application of Fuzzy Logic Controller (FLC) for Thyristor Controlled Series Capacitor (TCSC) to enhance over all stability of electric power systems. The proposed hybrid controller combines the advantages of FLC and a conventional PI controller. In this work, we consider Single Machine Infinite Bus (SMIB) system installed with Power System Stabilizer (PSS) and Fuzzy-PI based TCSC Controller. In order to test effectiveness of these controllers, simulations are carried out in different loading conditions under a symmetrical three-phase short circuit fault at generator terminals. The response of Fuzzy-PI controller is compared with that of the PI controller. The simulation result shows that the Fuzzy-PI controller has outstanding operation in fast damping of power system oscillations.
