COMPARISON OF DAMPING PERFORMANCE OF CONVENTIONAL AND NEURO-FUZZY BASED POWER SYSTEM STABILIZERS APPLIED IN MULTI-MACHINE POWER SYSTEMS

Duraiswamy Murali – Marimuthu Rajaram

   The objective of this paper is to investigate the power system damping enhancement via power system stabilizers (PSSs). However, the conventional power system stabilizers (CPSSs) have certain drawbacks. There are many techniques proposed in the literature for damping improvement of low frequency power system oscillations. In this paper, adaptive neuro-fuzzy inference system (ANFIS) technology has been proposed to coordinate the CPSSs in a multi-machine power system. The time-domain simulations are carried out in Matlab/Simulink environment to validate the effectiveness of the proposed control scheme under different operating conditions.

Keywords: ANFIS, CPSS, damping enhancement, low frequency oscillations, multi-machine power system, time-domain simulation
