Simulation and Experimental Verifi cation of Alternating Current Electric Arc Furnace with Static Var Compensator

Non linear and erratic loads like an alternating current electric arc furnace with almost instantaneous fl uctuations with its active and reactive power requirements, leads to power quality issues such as poor power factor, harmonic generation etc. We propose to simulate such unique load and prepare its simulation for active and reactive power requirements. Static var compensator is perfect solution for eliminating the above mentioned threats to power quality. SVC behaves like shunt connected variable impedance, which can either generate or absorbs reactive power [2]. Through this review we also present simulation of SVC with AC EAF and prove that all reactive power required by AC EAF during its operation at various power stages is supplied by the SVC only and net reactive power drawn/ supplied from system is almost zero in line with actual field practice.
