Simulation and Research of the EAF Characteristics under Voltage Flicker using MATLAB

摘要

Power quality is becoming a more concern of today's power system engineer due to the rapid growth of non-linear loads, such as power electronic control equipment and electric arc furnace (EAF). Harmonics and voltage flicker are the power quality problems which are introduced to the power system as result of non-linear behavior of the electric arc furnace operation. There are numbers of arc furnace models. This paper presents a time domain model which is used to study its behavior on the power system using MATLAB. To analyze the method, several characteristics for different operating conditions are investigated.
