Abstract

Ultrahigh-power AC electric arc furnaces (AC EAF) are considerable flicker sources in an electric power system. Often several steel plants containing AC EAF are connected in different network nodes and are working simultaneously. The flicker in the electric power system caused by simultaneous operation of several AC EAF is a result of the interaction and the summation of the flicker caused from each operating AC EAF. The method of the analysis of the influence of a particular fluctuating load on the flicker level in the HV transmission system based on direct on-site measurements as well as the mathematical modelling of the flicker emission from particular flicker sources is described in the offered paper.
