| Abstract: | This paper deals with dispersed installation of voltage‐detection based shunt active filters for harmonic damping throughput a power distribution system. A main objective of the active filters is to achieve damping of harmonic propagation coming from series/parallel resonance between capacitors for power factor correction and line inductors in the distribution system. Either a harmonic current source or a harmonic voltage source is connected to a distribution system simulator consisting of two distribution feeders, each of which is rated at 200 V and 20 kW. A couple of active filters are installed to the simulator. As a result, it is clarified by experiment that dispersed installation on the end bus of each feeder is effective in attenuating the harmonic propagation. © 2001 Scripta Technica, Electr Eng Jpn, 138(1): 14–23, 2002 |
