Abstract :
Based on the improved nonlinear time-variable resistance model of electric arc furnace, the power supply system simulation model is established for voltage fluctuation study by means of MATLAB/POWER system. A flexible power supply method for EAF is presented in which SVG is used, the paper applied instantaneous reactive power theory to measure instantaneous reactive current, PWM is used for current tracing feedback control to make SVG produce the required reactive current. The simulation result shows that the method is valid to overcome power supply voltage fluctuation and flicker
