Abstract :
The Electric Arc Furnaces is time varied and non linear load that up to now so many models are suggested for the analysis of its operation. This kind of unstable load can make many problems in power quality (i.e. Flicker, Sag and Swell), unstable voltage and current and harmonics for the power transmission network. In this essay, you can find a new model for making a model for the Electric Arc Furnaces by complex two methods of Casi and Mayre and choosing a complex function that can cover both two methods. In this method, Electric Arc Furnaces is considered as a load with a variable admittance and corrosion of electrodes is considered as a parameter variable by time. At the end, you can find the result of simulation and its comparison with the other models.
