Abstract :
This paper presents design of a fuzzy logic controller to prevent an electric power system to losing synchronism after a large sudden fault and to achieve good postfault voltage level. The developed fuzzy logic controller (FLC) accepts speed deviation and acceleration as inputs and generates the control signal. The simulation study is carried out based on a single machine infinite bus power system. The performance of this controller is compared with a nonlinear state feedback linearizing controller (NFLC).
