Effectiveness of fuzzy logic controller on performance of unified power flow controller

In this paper a concert of fuzzy logic controller based unified power flow controller and its comparison with control tool based on P at different phase variation is shown on the basis of results using MATLAB, so that effectiveness of fuzzy logic controller based UPFC can be boosted. To governor the real and reactive power flow, and also to improve the system constancy in a transmission line a cutting-edge and flexible scheme of FACTS devices are used in which UPFC is one of them. Controllers which are in the control mechanism have major properties on monitoring power flow and improving the system constancy of UPFC. MATLAB/Simulink results specify that when a three phase fault is applied for 0.2 sec on one of the transmission lines, for controlling real/reactive power flow using different control tools based on P & Fuzzy controllers, fuzzy based control tool shows better concert in power flow controlling. The study can be performed with MATLAB/Simulink.
