Study & Comparison of Various Topologies of Dynamic Voltage Restorer & Its type: A Review

Electrical Engineering

Power quality is one of the most important area of power system which we cant ignore as the lot of protective accessories, huge capital and customer safety are the important concern besides providing just a power supply. Power quality is ability of system to provide constant, pure sinusoidal and distortion less supply to power system. Now a days due to advanced technologies interruptions occur in the system which we need to compensate at proper time. For this purpose a research is made to reduce the effect of using non linear load on power system. One of the device used to compensate the unwanted disturbances in power system is studied in this paper . This study represents analysis of various types of dynamic voltage restorer (DVR) used in transmission line. Dynamic voltage restorer is power electronics controller used in series with transmission line to inject three phase voltage. This paper compares various topologies of three phase DVRs. In this research various technologies related to DVR are compared with each other.
