Slimane Touil, Djilani Ben Attous . Effect of Different Membership Functions on Fuzzy Power System Stabilizer for Synchronous Machine Connected to Infinite Bus. International Journal of Computer Applications. 71, 7 ( June 2013), 20-26. DOI=10.5120/12371-8716
The effectiveness of power system stabilizer (PSS) in providing damping and improving the dynamic response is well established. In this paper focuses, the performance of single machine infinite bus is studied with fuzzy power system stabilizer (FPSS). The generator is represented by the standard K-coefficients as second order system. The mechanism to discuss the rules is described and the performance is investigated for trapezoidal, triangular and Gaussian membership functions of input and output variables. For FPSS, speed deviation and acceleration deviation are taken as input. The system is simulated in SIMULINK environment and performance is investigated for transients due to change in input of varying magnitude.
