A Study on Performance of Fuzzy Logic PSS and Fuzyy Model Reference Learning PSS

Power system stabilizer (PSS) can provide supplementary control signal to the excitation system to damp electromechanical oscillations between interconnected synchronous generators and to improve dynamic performance. This paper presents a comparison study between a fuzzy logic PSS (FLPSS) and a fuzzy model reference learning PSS (FMRLPSS) to improve the stability of a synchronous generator. A fuzzy logic based PSS and fuzzy model reference learning are designed and simulated using MATLAB software package. The simulation results are compared. It is shown that the FMRLPSS is superior to FLPSS
