Development and proof examination result of Active Filter for Power Distribution Systems

Abstract

Certain orders of harmonic currents are generated when many non-linear loads are used in the electrical distribution systems. Then the generated harmonic currents are amplified due to the resonance between the system impedance and the static capacitors under the leading power factor conditions. As a result, the voltage distortion grows up.
To solve this problem, an active filter is developed for distribution system and its field test results are presented and discussed in this paper.
