Abstract

The voltage flicker emission levels caused by electric arc furnace operation can cause objectionable disturbances in residential, incandescent lamp based light sources. Installation of a newly designed SPLC (smart predictive line controller) beta unit in the arc furnace power supply system of Co-Steel Lasco (46 kV, 100 MVA) reduced the flicker levels at the source. The paper presents the SPLC system description, details of installation, current and voltage fluctuation profiles, flicker measurements and operational benefits.
