Many customers who require high reliable power, utilities provide dual feeds; i.e. service to a facility comes from two independent transmission lines. Maintaining power quality is an important issue in the transmission and sub transmission system. Unified Power Quality Conditioner is the optimal solution to ameliorate the quality of power. Many researchers analyzed the performance of UPQC with various control techniques. Recent advanced UPQC is the Multi Converter Unified Power Quality Conditioner (MC-UPQC). Conventionally the MC-UPQC is controlled using the PI controller for DC link voltage control. This paper proposes Fuzzy Logic Controller (FLC) to enhance the performance of the MC-UPQC to improve the power quality in a multi bus with sub transmission system. In this article MC-UPQC is designed with two series and one shunt voltage-source converters (VSC). It is nominated to follow out in adjacent transmission lines to improve the quality of electric potential. In the proposed system, all converters are connected back to back on the dc side and share a common DC-link capacitor. It results in the transfer of power from one line to adjacent line to compensate for voltage sag/swell. Performance of MC-UPQC using the conventional PI controller and proposed FLC are compared. Harmonics produced by voltage distortion is also reduced within IEEE standards. The whole system is simulated and analyzed using MATLAB7.7/ Simulink.
