Abstract:AC arc furnace power load is common in power system, its nonlinear characteristics have many adverse effects on the power system, such as voltage flicker, voltage fluctuation, harmonic current and low power factor, etc. To accurately obtain the effect of electric arc furnace on the power quality of electric arc furnace, an accurate simulation model is necessary. This paper uses PSCAD software and builds a simple arc furnace time domain simulation model base on studying the working principle of electric arc furnace and all kinds of time domain, frequency domain model, obtains the voltage flicker caused by arc furnace, the current harmonics, voltage harmonic, voltage fluctuation and other kinds of power quality problems. Finally, simulation data are compared with the measured results,proves the superiority of the model.
