Power quality is one of major concerns in the present area. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end use equipment’s. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is ...

An interline dynamic voltage restorer (IDVR) is a novel c o m p e n s a t i o n piece of equipment for sag mitigation It is made of several dynamic voltage restorers (DVRs) with a common dc link, here each DVR is connected in series with a distribution feeder. In the sag period, active power is transferred from a feeder to other one and voltage sags with long durations can be mitigated. IDVR co...

The quality of voltage and current delivered by the power utilities has become a major concern of the modern industries. These power quality problems are voltage sag and harmonic which can cause problems to the industries ranging from malfunctioning of equipments to complete plant shutdowns. In this paper, the proposed Quality Power Provider (QPP) modeled by simulation is able to compensate the...
