Abstract :
This paper introduces a fuzzy controller as a power system stabilizer (PSS). The fuzzy controller has been designed to provide a supplementary signal to the excitation system of the synchronous generator. Three proposed types of fuzzy control algorithms are inspected and tested in the case of single machine that connected to the network, for various types of disturbance. To show the effectiveness of the proposed controller in damping oscillations a three-phase short circuit condition under various loading conditions is presented to illustrate the application of the developed methodology. The obtained results show that the proposed controller for stabilizing power system can provide very good damping characteristic, comparison with the conventional PSS, through wide range of operating condition for power system and improves dynamic operating of the system substantially.
