Active Power Feeder for Electric Arc Furnaces

The Active Power Feeder is an advanced grid friendly technology designed to assist steel plant managers, operators, and maintenance engineers working with electric arc furnace-based meltshops. It enhances operational efficiency, improves product quality, and reduces operational costs by increasing productivity, extending maintenance intervals, and simplifying operations through advanced power control, dynamic current control, and integrated monitoring systems.

The Active Power Feeder for electric arc furnaces integrates advanced modular multilevel converters (MMC) to deliver balanced real power from a medium-voltage supply system. This system offers precise control over furnace operations, enabling fast current control and minimizing power fluctuations. The result is a more stable and efficient electric arc furnace melting process and reduced operational costs.
