Three-Phase Line-Interactive Dynamic Voltage Restorer with a New Sag Detection Algorithm

A New Topology for Interline Dynamic Voltage Restorer Based on Direct Three-Phase Converter

In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology contains two direct three-phase converters which have been connected together by a common fictitious dc-link. According to the kind of the disturbances, both of the converters can be employed as a rectifier or inverter. The converters receive the required compensation energy from the gird thro...

Using of Dynamic Voltage Restorer (DVR) to Mitigate Sag & Swell Voltage during Single Line to Ground & Three- Phase Faults

Mitigation of voltage sag/swell using Dynamic voltage restorer (DVR)

The most noticeable topic for electrical engineering is power quality in recent year. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency. Utility distribution networks, sensitive industrial load and critical commercial operation suffer from various types of outages and service interruption can cost significant financial losses. One of the major prob...

Implementation of Dynamic Voltage Restorer for Mitigation of Voltage Sag

Power quality is one of major concerns in the present. It has become important, especially with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to improve the power quality. In this paper, emergency control in distribution systems is discuss...

The Effectiveness of Dynamic Voltage Restorer with the Distribution Networks for Voltage Sag Compensation

This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...
