English Abstract

Fuzzy logic controllers have been designed for power sysgtem stability enhancement. The proposed fuzzy PSS was tested on a single machine as well as multimachine systems. A closed loop optimal control strategy is taken as a knowledge base for the fuzzy design. The designing of membership functions and set of rules which are selected from the information using minimum time strategy. Three different fuzzy logic controllers were developed and tested. The response for a single machine infinite bus system with these control strategies are compred with the method reported in the literature. A simplified algorithm which is computationally efficient, has also been examined. From simulation of the proposed fuzzy algorithm on the single machine and multimachine systems it has been observed that the proposed minimum time based fuzzy logic controller is robust. It can provide a simple and effective method of stabilization and its computationally very efficient.
