Voltage Sag and Swell compensation using DVR to enhance Power Quality
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 2
Abstract
The quick developments in power electronic technology have made it possible to mitigate voltage disturbances in power grid. Among the voltage disturbances challenging the trade, the voltage sags are considered to be the most necessary drawback to the sensitive loads. Dynamic voltage restorer (DVR) is a series connected power electronic based device which will quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. DVR is recognized to be the simplest effective solution to overcome this problem. The first advantage of the DVR is keeping the users always on-line with prime quality constant voltage maintaining the continuity of production. In this paper, the advantage of including DVR in distribution system for the purpose of voltage sag and swell mitigation is interpreted. The DVR presented here is based on the concept of dqo. The control method is found very efficient for identifying and clearing any power quality disturbance in distribution systems. Results of simulation using Matlab/Simulink are shown to prove the importance of this scheme.
