Analysis of harmonic propagation in a power distribution system: An application of a distributed constant‐circuit model

This paper discusses harmonic propagation and damping in a long‐distance distribution feeder having many capacitors for power factor correction, and presents harmonic damping characteristics of a shunt active filter based on voltage detection. A distributed constant‐circuit model for the feeder is derived to perform analysis with the focus on harmonic propagation and damping. As a result, it is clarified by theory and experiment that harmonic propagation throughout the feeder can be mitigated by installing the active filter, which acts as a harmonic terminator, on the end terminal of the feeder. © 2002 Scripta Technica, Electr Eng Jpn, 139(1): 73–81, 2002; DOI 10.1002/eej.1148
