Converter based solution to power quality problems on radial distribution lines

In this paper it is shown that the power converter-based power quality manager is a viable solution to power quality problems on radial lines. It is capable of harmonic isolation, improving voltage regulation and flicker compensation simultaneously. These functions can also be implemented independently. The power quality manager 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 converter based static VAr compensator.
