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 (AHFs). 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 discuss when and where these advantages apply. Additionally discussed is the simplicity in selection of the AHF. The author present specific examples for the various applications to which AHFs have been applied.
