A practical model of electric arc furnace can help design filters to delay the use life of power line electro-insulating material. This paper proposed a practical simulation model of electric arc furnace. The model is built based on its real output characteristic. It can out put a distort current composed up of n harmonics and non-integer harmonics which re-appear the arc’s cutting off and short circuit phenomenon in melting stage. The current can be set to extrude unbalanced current, interrupted current and half wave imbalance current of each phase. It can also simulate the voltage distortion and flicker effect to other loads. A flicker measure plat is carried out and the model proved to be feasible and realizable. It can realize electric arc furnace output characteristic and is easier to be connected to the power system.
