Abstract


Voltage sag which is reduction in rms voltage for a short duration could be caused by short circuits, the connection of overloads to system and starting of large motors. The interest to study the voltage sags is mainly because of the problems which they cause on several types of power system equipment: adjustable-speed drives, process-control equipment, and computers are notorious for their sensitivity. In this research description and definition of voltage sag and swell and their destroyer effects on power system is presented. Also the effect of voltage sag/swell mitigation using dynamic voltage restorer (DVR) is investigated. Due to educational purpose of this paper to teaching compensation advantages to graduate students the well-known software MATLAB-SIMULINK has been employed to simulate and investigate the effects of voltage sag/swell mitigation.
