On a Matlab/Simulink of Power Quality Issues in Distribution System with the Presence of Electric Arc Furnaces and Mitigation Solution Using Active Filter

The non-linearity of the conductance of the electric arc furnace causes voltage flicker and harmonics in power systems. Nowadays, the application of electric arc furnaces in the steel production industry in Vietnam also results in the aforementioned power quality issues and it has been critical to find appropriate solutions for mitigation of those issues recently. This paper develops a time-domain simulation of electric arc furnace that can show power quality issues such as voltage flicker and harmonics in the distribution system and the solution using an active filter for power quality improvement in MATLAB/SIMULINK and thus, it is possible to assess the influences of different parameters of electric arc furnace on the design of active filter. The comparison of simulation results and experimental results obtained from the distribution system of the factory of Thien Phat Company has been conducted.
