ROLE OF DYNAMIC VOLTAGE RESTORER IN POWER QUALITY – A REVIEW [pp 01-05]

Balwant Barkhaniya, Madhu Upadhyay

Abstract – Dynamic Voltage Restorer (DVR) is a modern and key custom power device to maintain the power quality. The DVR is a series compensator implemented to mitigate voltage sags and swell and to restore load voltage to its rated value. The Dynamic Voltage Restorer (DVR) is of high dynamic response, flexible and efficient solution to voltage sag and swell problem finally power quality problems using a robust in-phase…

IMPLEMENTATION OF UNIFIED POWER QUALITY CONDITIONER (UPQC) FOR POWER QUALITY IMPROVEMENT – A REVIEW [pp 06-09]

O.P. Shrivastava, Madhu Upadhyay

Abstract – The Unified Power Quality Conditioner (UPQC) is multifunction device employed in the distribution system of a power system network to alleviate the disturbances that affect the performance of sensitive and/or critical load. UPQC can also be implemented for load balancing, voltage regulation, voltage and current harmonics alleviation, alleviation of voltage sag, voltage swell and power factor correction in….

DESIGN & SIMULATION OF DYNAMIC VOLTAGE RESTORER FOR POWER QUALITY IMPROVEMENT [pp 10-15]

Balwant Barkhaniya, Madhu Upadhyay

Abstract – Power quality issues is a key issue in recent time where mainly the disturbances like voltage sag, voltage swell and faults are the mail causes. In this paper Dynamic Voltage Restorer (DVR) is implemented to mitigate the vulgate sag, swell and faulty disturbances. A dynamic voltage restorer (DVR) is a custom power tool used to correct the voltage sag by voltage as well as power injection. The DVR is a series type of compensating device implemented to….
