Fuzzy logic based automatic voltage regulator For damping power oscillations

Abstract

This paper proposes a novel fuzzy logic based automatic voltage regulator. The proposed controller has one control loop, i.e. the voltage control loop, which function as automatic voltage regulating unit of synchronous machine. The input signals for voltage control are error of terminal voltage and its derivative. Comparison studies have been performed to see the performance of the proposed controller with the conventional automatic voltage regulator and conventional automatic voltage regulator along with power system stabilizer.
