Harmonic and transient overvoltage analyses in arc furnace power systems

摘要

Guidelines for analyzing harmonics and transient overvoltages generated by arc furnaces are presented. computer simulation techniques for creating accurate models for the analysis of arc furnace power systems are 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. General practices and designs encountered in arc furnace power systems are discussed as are possible solutions to common problems associated with arc furnace power systems. Shunt capacitor bank arrangements, harmonic filter design, ferroresonance, virtual current chopping, the use of surge capacitors, and surge arresters are discussed.
