Power systems are subjected to low frequency oscillations due to disturbances. Such oscillations may sustain and grow to cause system separation if adequate damping is not available. To enhance system damping, generators are equipped with Power System Stabilizers (PSSs) that provide supplementary feedback stabilizing signals in the excitation channel. The fuzzy logic system is concerned with the stability of the electric power system, and the excitation governor controllers are used to stabilize a synchronous machine infinite bus system. The considerable effort has been directed to the development power system stabilizer. This paper incorporation of a simple method for the design of reliable decentralized stabilization using two controllers.
