Abstract
A Power System Stabilizer (PSS) is the absolute most cost effective approach of increase the system positive damping; enhance the steady-state stability margin. The stability of power electrical networks is really a key factor for the delivery of top quality energy. This study compares the power system stabilizer based on fuzzy logic control with the conventional power system stabilizer for Single Machine Infinite Bus System (SMIB). The objective of designing the fuzzy stabilizer could be the increased stability and improving the dynamic response of the single machine system linked to the infinite bus. A Fuzzy Power System Stabilizer (FPSS) design using discrete inputs is presented. To offer satisfactory behavior in the whole region of operation of the generator, additional signals namely, generator's active and reactive power are utilized as inputs to FPSS. The results of simulations performed on the model of nonlinear system shows good performance of the Fuzzy controller. SMIB system was selected due to the simple structure, that will very useful in understanding the effects and implications of the PSS.
