Abstract

This paper proposes a novel custom power device (CPD), called a Universal Power Quality Conditioner (UnPQC), whichenhanced the quality of power in a distribution system. UnPQC consists of shunt and series compensators without a commonDC link. The series compensator of the presented system, also known as Transformerless Dynamic Voltage Restorer (TDVR),eliminates power quality problems related to voltage without utilizing any injecting transformer. The shunt compensator of theproposed system consists of an improved DSTATCOM (Distribution Static Compensator) topology, which mitigates the currentharmonics originating from the nonlinear loads with a reduced DC link voltage. UnPQC is more suitable for applications whereweight and size of the CPDs are critical factors. A simulation was carried out to verify and validate the performance of theUnPQC and the results demonstrate superior performance in minimizing voltage and current related power quality problems.
