An Approach for apply DVR to Moderate Voltage
Sags and Swells
International Journal of Innovations in Engineering and Science, 2 (8):
9-13 (July 2017)Abstract
Improved and controlled power quality is one
of the necessary fundamental in any electrical industry
for the utilization of resources. On the other hand
critical problems in power quality have been predictable
such as sags, swells, harmonic distortions and some of
the interruptions. These sags and swells are found and
have collision on the electrical devices and electrical
machines. So needs to be compensated to failure. The
DVR is one of the tradition power device used for the
compensation of voltage sag and swell with an
advantage of active/reactive power control.
A most important volume of literature reported in past
quite a lot of years on different configurations of DVR
and different control technique used in it which have
been describe in this paper. In context of this a detailed
review on DVR has been presented with different
possible power circuit topologies and control techniques
available to reconcile these power quality issues. In this
paper will put in in better selection of control policy
DVR for a particular requirement.
