Abstract

This paper presents an application of fuzzy control to determine the control signal of static var compensator (SVC) for reactive power compensation and power factor correction. 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. The effectiveness and feasibility of the TSK (Takagi-Sugeno-Kang) and Mamdani type fuzzy controllers for thyristors firing control in SVC is compared. Effectiveness of the proposed technique is demonstrated by simulation studies on a single machine infinite bus system. Results obtained show improvement in the overall system characteristics using the proposed adaptive fuzzy logic SVC controller.
