Electric arc furnace is unbalanced, nonlinear and time varying loads, which can cause many problems in the power system. Voltage variation problem is the major focus of the power system because the loads can vary anytime. Power quality issue has a very high attractive for power system engineers and try to solve these problems by several effective ways. In this thesis, Static Var Compensator (SVC), thyristor controlled reactor compensation with thyristor switched capacitor (TCR-TSC) type is designed and its performance is simulated in the case studies. This unique design of this device (SVC) is used for reactive power compensation for nonlinear loads such as electric arc furnace (EAF) in an industrial plant. Moreover, the SVC is more effectively enhance the voltage stability. Single tuned passive harmonic filter can reduce total harmonic distortion (THD) caused by thyristor controlled reactor of SVC. The installation site for this thesis is No. 1 Iron and Steel Mill, Pyin Oo Lwin. And then, data is taken from this Steel Mill. Simulation results will be provided by using MATLAB/SIMULINK.
