Using Fuzzy Logic and Static VAR Compensator to Reactive Power Compensation and Power Factor Correction

Abstract: In this paper Static Var Compensator (SVC) is proposed for reactive power compensation and power factor correction. The TCR is operated automatically by a Fuzzy Logic Controller (FLC). The ability of the TSK (Takagi-Sugeno-Kang) and mamdani, two typical types of fuzzy controllers, for thyristors firing control in SVC is compared. Input signals for the FLC are chosen as load reactive power and initial firing angle of thyristors. The control signal is calculated using fuzzy membership functions. MATLAB/Simulink based simulation is utilized to demonstrate the comparison two types of controllers in SV
