Abstract

Power quality is one of the major concerns in the era of power system. Power quality problem occurred due to non- standard voltage, current or frequency, that result in a failure of end user equipment. To overcome this problem, Dynamic Voltage Restorer (DVR) is used, which eliminate voltage sag. This paper narrates the application of DVR to optimize the power quality problems such as voltage sag,The DVR is a power electronics based device that is commonly for voltage sagmitigation at the point of connection. A control technique based on a proportional (P) controller is implemented. In fact with the aid of Pulse width modulation (PWM) inverters capable of generating accurate high quality voltage waveforms from the power electronic device. Simulation results shows the effectiveness of proposed method by MATLAB.
