“… Both sintering devices, induction furnaces and arc furnaces are heavy harmonic sources. The harmonic examination of the arc furnaces has already been done in literature well-known [10], [12], [13], [18]- [21], [23], [28]. The harmonics of an electric current assisted sintering system is to be examined in the near future by the present authors.…”

“…Electric arc furnaces (EAF) are systems used for heating materials with electric arc. Arc furnaces which are also high power metallurgical devices like resistive sintering systems are commonly used in industrial settings to heat and mold metal and their power system harmonics and power requirements have been examined in literature [10], [12], [13], [18]- [21], [23], [28]. Arc furnaces range in size from only a few dozen grams (used in research laboratories for some specific purposes) to about hundreds ton units (used for high volume industrial applications).…”

Industry 4.0, a new industry revolution, is happening now and several developed countries are leading the path. Internet of things (IoT) is also encompassed by Industry 4.0. In the future, more devices in factories are to be connected to Ethernet or Internet. However, this makes the companies, devices and researchers vulnerable to cyber-attacks. Recently, some cyber-attacks which have happened to some companies or countries verify the danger. Sintering systems and furnaces are used for research by universities and for series manufacturing by factories. Arc furnaces and induction furnaces are also commonly used devices in metal factories. A sintering system, an arc furnace or an induction furnace which is connected to Internet or Ethernet may also be under cyber-attack threat. The danger may be prevented by taking necessary precautions. In this study, these threeproduction systems are first briefly introduced and then inspected assuming that they have been connected to internet and examined with considering cyber-attack point of view. Some basic solutions against cyber-attacks to the aforementioned devices are suggested.

In recent years, non-linear loads on the distribution side are increasing rapidly. Notably, the electric arc furnace (EAF) is the most used non-linear load due to its diverse applications for industrial needs. However, EAF has some disadvantages like uneven distribution of heat inside the furnace, release of unwanted gases, increased level of harmonics, and Flickers in voltages. Specifically, power quality concerns are more and need comprehensive solutions. In this work, a matrix converter (MC) along with static VAR compensator (SVC) is proposed, and the hybrid exponential-hyperbolic furnace model is adapted in MATLAB platform. Simulations are carried out for different cases and the observed results are compared with existing methodologies. It was perceived that the power quality parameters such as peak current and voltages, total harmonic distortions (THDs), voltage flickers, and power factors are enhanced compared with existing methodologies. Precisely, the THD of current and voltage attains a prime rate of about 2.85% and 29.54%, respectively. Moreover, the proposed model’s voltage flicker and power factor offer a grander scale of about 1.26% and 0.9975, respectively. The enhanced scheme provides more significant advantages to the large-scale steel manufacturing plant with EAF.

“…Dynamic loads always generate harmonics in the power system and reduces the performance of electrical equipment. Electric arc furnace is such type of load which causes voltage fluctuation when connected to the grid in the electrical system thereby leading to the problem of voltage flicker [5], [6]. These power quality problems results in reduction of efficiency and performance of electrical equipment.…”

Voltage flicker is the disturbance in voltage waveform due to the variation of load in the power system. Voltage flicker is the most important factor that effects the power quality of an electric arc furnace. voltage flicker causes the fluctuation in the light source that varies from time to time. Therefore, this paper deals with the study of Flexible AC Transmission Line (FACTS) based distribution static synchronous condenser (D-STATCOM) device that alleviates the voltage flicker from the arc furnace. The arc furnace is acting as current source and simulated in the MATLAB for obtaining the result.
