Abstract :
The authors present guidelines for analyzing harmonics and transient overvoltages generated by arc furnaces. Computer simulation techniques for creating accurate models for the analysis of arc furnace power systems are also discussed. Simulation guidelines are outlined in detail to assist the power systems engineer in performing a complete and accurate study of arc furnace power systems. These guidelines can be applied to melting and ladle furnace applications. General practices and designs encountered in arc furnace power systems are discussed. Possible solutions to common problems associated with arc furnace power systems are also discussed. Discussions of shunt capacitor bank arrangements, harmonic filter design, ferroresonance, virtual current chopping, the use of surge capacitors and surge arresters are also included
