Voltage flickers and harmonics are power quality (PQ) problems in the electric system during a variation and arc furnace (AF) adaptability. AF creations must determine a harmonic and flicker. This article evaluates complex AF systems. This article presents a newly established time domain (TD) static become to on an AF's V-I attributes (VIA). Static arc configurations are useful for harmonic analyses, but dynamic methods are needed for PQ studies, especially voltage flicker analysis. The MATLAB-based dynamic AF configuration is simulated for four different configurations. A response with configurations 1 and 4 varies from the real AF outcomes. The simulation results and numerical finding shows that configurations 2 and 3 are much more appropriate and produce better results for minimum 3rd harmonics for arc current, arc voltage, and point of common coupling (PCC) voltage. The novelty of this configuration is that the energy transferred to the load by the AF during the cycle of operation has been identified, making the developed scheme more reliable and dependent on the load's operational conditions. After that, effective applications of these configurations and other configurations' accuracy should be clarified.

“…For the constant component and even harmonics in EAF currents, the presence of a "valve effect" [7] arises due to unequal back-electromotive force (EMF) of electric arcs when alternating the anode and cathode on the electrode and charge. In real conditions on the operating equipment, the valve effect is also the cause of the intermediate interharmonics emergence, which are caused by different forms of positive and negative half-wave current.…”

The authors of the article carried out experimental studies of the harmonic current composition of arc steelmelting furnaces of various capacities and classes operating at various metallurgical enterprises in Russia. This made it possible to carry out a comprehensive analysis of the changes in the higher current harmonics of the electric steelmaking units, to identify patterns of changes in individual harmonic components, as well as to determine the average and maximum harmonic levels for arc furnaces of each type. Also, a comparative analysis was made of the change rate of the total effective values of even and odd harmonic components, which showed an important pattern in exceeding the rate of attenuation of even harmonics of an arc furnace over odd ones several times. On the basis of this, it was shown the expediency of using the rms current of even harmonics for the purpose of diagnosing the melting stages in an electric arc furnace with the classical technological process. This principle formed the basis for the structure of the new control system for the electric mode of the furnace, which implements the diagnostic technique for the melting stage according to the harmonic composition of the electric arc current signal.
