Universal Power Quality Conditioner (UnPQC) for enhancing the power quality in distribution system

This paper proposes a novel custom power device (CPD), called a Universal Power Quality Conditioner (UnPQC), which enhanced the quality of power in a distribution system. UnPQC consists of shunt and series compensators without a common DC 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 the proposed system consists of an improved DSTATCOM (Distribution Static Compensator) topology, which mitigates the current harmonics originating from the nonlinear loads with a reduced DC link voltage. UnPQC is more suitable for applications where weight and size of the CPDs are critical factors. A simulation was carried out to verify and validate the performance of the UnPQC and the results demonstrate superior performance in minimizing voltage and current related power quality problems.
