Characteristic study of three-phase AC electric arc furnace model

The electric arc furnace can cause voltage flicker and produce harmonics that can impact the power system. This is due to the characteristics of electric arc furnace as a nonlinear load. Designing an electric arc furnace model is intended to study the characteristics of the electric arc furnace and its impact to the power system. The voltage flicker model of Chua's Chaotic Circuit and differential equations of the arc length will be used in the modeling of the electric arc furnace. In accordance with the purposes of this study, the model of electric arc furnace will be applied to the design and placement plan in the power system. Before applying the electric arc furnace model to the power system, the v-i characteristic of electric arc furnace, harmonics, flicker, and other preinstallation requirements will be studied as mentioned in the grid code.
