Analysis of DC arc furnace operation and flicker caused by 187 Hz voltage distortion

This paper analyzes an unusual flicker-like disturbance during the operation of a DC arc furnace. A harmonic resonance, excited by an excessive amount of uncharacteristic converter current harmonics, was the main cause of the disturbance. A study was performed in which the phenomenon was duplicated...

Zusammenfassung:This paper analyzes an unusual flicker-like disturbance during the operation of a DC arc furnace. A harmonic resonance, excited by an excessive amount of uncharacteristic converter current harmonics, was the main cause of the disturbance. A study was performed in which the phenomenon was duplicated with the Electro-Magnetic Transients Program. The simulation model and results are described. The generation of uncharacteristic converter current harmonics under normal and abnormal converter operation are demonstrated. The significant conditions leading to the unusual 187 Hz disturbance and flicker complaints are discussed.< >
