Power Quality Improvement using FC-TCR (SVC) with Fuzzy Logic Controller

To transmit or distribute fixed amount of power at fixed voltage, the conductor have to carry more current at low power factor. This necessities a large conductor size. The large current at low power factor cause more copper loss in power system as well as increase kva rating of equipments. This low power factor also cause poor voltage regulation and reduce power handling capacity of power system. All these problems can be removed by static var compensator (svc). Fixed capacitor thyristor controlled reactor can be used for power factor correction, flicker reduction, and steady-state voltage control, and also have the benefit of being able to filter out harmonics from the system. In this paper FC-TCR with fuzzy logic controller is simulated using Matlab simulink.
