Abstract

This paper narrates the application of DVR to optimize the power quality problems such as voltage sag, voltage swell and harmonics. Among all these three power quality problems, two are identified as the major concern to the customers namely voltage sag and voltage swell. One of the well known solutions to mitigate the power quality problem is to inject the voltage as well as power into the system with the help of DVR.The DVR is a power electronics based device that is commonly for voltage sag and voltage swell mitigation at the point of connection. A control technique based on a proportional integral (PI) 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 show the effectiveness of proposed method by MATLAB/Simulink.                                                                                                                                        

 Key words: Dynamic Voltage Restorer (DVR); Power quality; Pulse Width Modulation (PWM); Voltage Source Converter (VSC).
