Converter-based solution to power quality problems on radial distribution lines

In this paper, the authors show that the power converter-based Power Quality Manager (PQM) is a viable solution to power quality problems on radial power distribution lines. The PQM is capable of simultaneous harmonic isolation, improving voltage regulation and flicker compensation. These functions can also be implemented independently. The PQM is a hybrid device comprising passive components and a power converter. The converter power rating is lower than that required by an equivalent active filter or power converter-based static VAr compensator.
