As the popularity and use of the arc furnace loads in the industry increase, so does the power-quality problems as a result of this progress. The voltage flicker and the existence of harmonic load currents can be given as examples of adverse effects introduced by arc furnaces due to the voltage-current characteristic of the arc being nonlinear. Utilities and customers have been trying to minimize the effects otarc furnace loads on power quality as much as possible. In order to propose solutions to minimize these adverse effects of arc furnaces, the impact of these highly nonlinear, time-varying loads on the power quality of the overall power system should be investigated. For this, an evaluation procedure and its compensation methods were suggested - considering the simulation results in the MATLAB {simulink) environment.
In recent years, power quality issues have become more and more important in both practice and research. The Power Quality broadly refers to maintaining the near sinusoidal waveform of power distribution bus voltage at rated voltage magnitude and frequency. A Power Quality Disturbance could be defined as being “any power problem manifested in voltage, current, or frequency deviations that result in failure or mal-operation of customer equipment, or Power system equipment”. The increasing use of equipment sensitive to power system disturbances and the related economic aspects, the increasing awareness of power quality issues.
