Abstract

The paper describes the process of defining flicker emission limits and requirements
regarding power quality of a steel plant with electric arc furnace (EAF) equipped with a static
var compensator (SVC). As a first step flicker transfer factors from the point of connection to
selected substations with public customers (points of common coupling) were calculated by
Graz University of Technology, taking into account different grid topologies and background
flicker. Planning levels, flicker targets and requirements for the SVC were defined based on
those data. Using realistic flicker reduction factors and operational data of the new EAF,
expected flicker values for the 110 kV grid were forecasted. After commissioning of the
installation, new flicker measurements were performed to verify the calculations. Besides the
description of this process, operational experience with the new equipment is given.
