Upgrading SVC Controls Boosts EAF Performance at JSW, Ohio

Static VAR compensators (SVCs) in large electric arc furnaces, especially those above the 100-MW range, predominantly employ TCR technology, which has been used for over 30 years. While thyristor valves remain durable, control systems face obsolescence and integration challenges with new technologies. Instead of replacing the entire system, an upgrade solution from AMI Automation was implemented at JSW Steel in Mingo, Ohio, rejuvenating the control system. The latest AMI PXC platform was introduced, providing enhanced diagnostics and better digital furnace regulator integration. This upgrade revitalized operations, optimizing consumable use and boosting furnace efficiency.
