This paper discusses control characteristics of line-voltage regulation by a shunt active filter intended for installation on a power distribution system. Since the power circuit configuration of the active filter is the same as a static synchronous compensator (STATCOM), it is possible to regulate the line voltage by means of controlling an adequate amount of a reactive power. In this case, no harmonic voltage affects a feedback controller for the line-voltage regulation, because the active filter eliminates harmonic components from the line voltage at the installation bus. The dynamic performance is also investigated by computer simulation and experimental results. This paper proposes a new compensation scheme capable of reducing transient voltage fluctuations caused by a phase angle change in the installation bus voltage.
