Proper use of active harmonic filters to benefit pulp and paper mills

This paper is a basic primer for defining and applying active harmonic filters. Active harmonic filters (AHFs) are sophisticated electronic devices that offer significant advantages over traditional harmonic mitigation and displacement power factor correction methods. This paper introduces the AHF and discusses when and where these advantages apply. Additionally, the simplicity in selection of the AHF discussed. The author presents specific examples for the various applications to which AHFs have been applied.
