Abstract : AC traction load is generally a large single-phase load with dynamic characteristics due to which a significant negative sequence component of current (NSC) is drawn from the grid and harmonics are injected in voltage and current. This inflicts undesirable effects on power quality. This work proposes a unified power quality conditioner which is a combination of a shunt-connected distribution static synchronous compensator (D-STATCOM) and a series-connected dynamic voltage restorer (DVR) to mitigate the degradation of power quality. The D-STATCOM helps in reducing the NSC significantly and suppressing the harmonic distortions. DVR addresses the voltage sag caused by the shunt compensating device. Control strategies for D-STATCOM and DVR for the unified power quality compensator are presented. The system is simulated in MATLAB environment, and a comparative analysis is carried out under various loading circumstances. As a result, superior power quality is achieved with the proposed UPQC.
