ENHANCING VOLTAGE AND CURRENT CONTROL TECHNIQUES USING UNIFIED POWER QUALITY CONDITIONER

Abstract

In this paper, the process of designing of Unified Power Quality Conditioner (UPQC) including series active power filter, shunt active power filter, a dc link is shown for the reduction in harmonics. In this main focus is on the control system of UPQC that reduces the problem of voltage and current simultaneously. Industrial and sensitive loads can cause various types of power quality problems. Unified Power Quality Conditioner enhances electric power quality mainly at distribution level. By using UPQC problem of voltage sag, voltage swell and current distortion in distribution system can be easily reduced. Moreover, a comprehensive control strategy is also introduced to extract the compensating signals for the control of series and shunt active filters. The proposed control scheme to mitigate the power quality issues is simulated using MATLAB/ SIMULINK in power system block set.
