摘要：
Voltage flicker, a phenomenon of light intensity fluctuation is caused by large and rapid industrial load changes. The AC Electric Are Furnace is one of the major sources generating voltage fluctuations, deteriorating the power quality. In the present work, the voltage fluctuations produced by a 4 tonne AC EAF and its effect on the 11kV/0.566kV distribution system is analyzed. The EAF load is modeled based on field measurement data obtained from the AC EAF at a modern steel manufacturing plant, Chennai, Tamil Nadu, India. Voltage flicker mitigation studies with and without static var compensator are carried out. The low frequency voltage oscillations due to EAF load currents in the distribution system are eliminated by controlling the firing angle of the SVC. The PSCAD/EMTDC software is used for modeling and simulation and the results are presented.
