Effect of different arc furnace models on voltage distortion

In this paper, different arc furnace methods are reviewed for the purpose of harmonic analysis. In general, these models may be classified into time domain method and frequency domain method. The difference between these two methods is discussed and evaluated. In this paper, six typical arc furnace models from the time domain and frequency domain methods are selected to study their effects on harmonic analysis. Simulation results are also provided. Comparisons between these results show the effects of different arc furnace models on voltage waveform and percentage of harmonic components distribution, which provides a discussion of the differences between time domain and frequency domain methods. Finally, recommendations are made for the application of some of these models
