Abstract

In this paper, the effects of transformer replacement on the electric are furnace power system of an iron and steel plant have been investigated. The new operating strategy has been determined according to stable are and maximum productivity requirements. Based on these new operating conditions, the sufficiency of the existing flicker compensation system in terms of the load balancing, power-factor correction, and flicker have been examined. All investigations made in this work are supported by real-time measurements.
