Modeling and Harmonic Damping Effect of Shunt Active Filters for Dispersive Installation on Power Distribution Systems

Experimental verification of the effect of a voltage-detection-based shunt active filter for harmonic damping throughout a power distribution line

“…Figure 3 shows the control block diagram. The harmonic detection scheme is a voltage detection scheme in which the voltage of the active filter at the installation point is detected [9,10]. First, the installation-point voltage v is detected; when the dq transformation is performed at the source angular frequency, the fundamental component (60 Hz) becomes dc and the harmonic components become ac.…”

“…The shunt active filter of the voltage detection scheme [9,10] (active filter for power distribution systems) of this paper is aimed at the suppression of harmonic expansion in power distribution systems, and differs in objective and control method from the active filter for specific consumers installed near the harmonic generation source.…”

New trends in active filters for power conditioning

“…Moreover, dispersive installation of "multiple" shunt active filters on multiple feeders in a power distribution system causes neither harmonic propagation nor harmonic interference among them, and thus it is a viable and effective way of actively damping harmonic propagation throughout a power distribution system which is subjected to harmonic pollution caused by harmonic resonance and a number of unidentified harmonic-producing loads [49].…”

Power Quality Improvement using Voltage Source Converter (VSC) based Unified Power Quality Conditioner (UPQC)

“…There has been an increased use of power electronics equipment due to low cost and new technologies causing an increased interest for research and development in the area [1]. Active power filters (APFs) that have been explored in shunt, series and combination of shunt and series configurations to compensate for current and voltage based distortions will play an important role for better quality solutions [1], [2].…”
