A novel dual hysteresis controller for the management of a three phase dynamic voltage restorer [PDF]
HeliyonIn this work a novel control scheme for the three-phase dynamic voltage restorer has been proposed and validated. The proposed control strategy guarantees the source current waveform to be sinusoidal and at near unity power factor.

Mitigation of Voltage Sags and Voltage Swells by Dynamic Voltage Restorer [PDF]
International Journal of Electrical and Power Engineering, 2011 Modern industrial processes are based on a large amount of electronic devices such as programmable logic controllers and adjustable speed drives. Unfortunately, electronic devices are sensitive to disturbances, and thus, industrial loads become less tolerant to power quality problems such as voltage sags, voltage swells, and harmonics.

Application of Dynamic Voltage Restorer for Sag and Swell in Voltage
International Journal for Research in Applied Science and Engineering Technology, 2022 Abstract: This paper figures out the problem of voltage sag and swell and overcome it. The most important aspect of electrical engineering is power quality in the current time. Power quality issues occur to the occurrence of substandard voltage, which may be current and frequency which may be damaged to power system equipment. One of the most important

DSTATCOM Performance for Voltage Sag swell Mitigation
International Journal of Recent Technology and Engineering (IJRTE), 2020 The Indian economy has been growing at a fast pace since the beginning of this millennium. Due to constraints in the availability of fuel and environmental concerns, the power generation sector has not kept pace with other industrial sectors. One way of increasing the power availability is by reducing the high losses in the existing power transmission ...
