SUMMARY:Active power feeder:  A grid-friendly power supply for electric arc furnaces
DESCRIPTION:"The Primetals Technologies Active Power Feeder utilzes a modern AC converter system combined with the Primetals Melt Expert control system philosophy. By incorporating a Modular AC Converter, it is able to control the furnace currents and output frequency and voltage and moreover draw balanced active power from the supplying Medium Voltage Grid in a very grid-friendly way. Set points for furnace current, frequency and arc voltage are automatically adjusted according to the operational situation and stability of arcing.
The benefits on the grid side are a high reduction of flicker and harmonics and a cos phi close to 1. No separate compensation systems are required and additional power consumers like a ladle furnace will be compensated as well. The benefits on the furnace process side are a stabilized arc and controlled furnace currents. The reduced current fluctuations allow to increase the arc voltage, power input into the furnace and ultimately reduce the power-on time in the melting phase. Controlled currents and avoiding overcurrent situations reduce the stress and wear for the operational equipment and result in reduced electrode consumption. Furnace operation with low output frequency reduce the feeding losses and increase the efficiency in the flatbath pase.
The operation with Primetals Technologies Active Power Feeder does not require a furnace circuit breaker to interrupt the power input and does not require primary side reactors to stabilize the arc."
