DESIGN AND CONSTRUCTION OF DYNAMIC VOLTAGE RESTORER
Abstract
The boundaries are set for quality of electrical power that is being supplied to all
the power equipment to function properly. If these equipment are exposed to any
of the power quality problems then the malfunctioning of the equipment will occur.
Different loads will respond differently depending upon the type duration and
severity of the quality problem occurring n the system. Because of this reason the
need of study of power quality disturbances is currently under the study of
researchers. Different types of power quality problems occur in the electrical
power system that depend upon the frequency and magnitude of the voltage. The
most common type of voltage magnitude quality problem that occurs in the
distribution network is voltage sag. Voltage sag will cause in increase in current
and that will eventually damage the load side. In case of sensitive loads the voltage
sag mitigation can be done with the help of a Dynamic Voltage Restorer. This
research will focus on the Voltage sag mitigation technique in an interconnected
system for a sensitive load with the help of a Dynamic Voltage Restorer (DVR).
This technique can be used to mitigate the most dangerous Power Quality
problems in different sensitive parts of the Power system.
