Analysis of Dynamic Voltage Restorer for Voltage Profile Improvement

Javed A Dhantiya, Amin S Kharadi, Ashraf M Patel


 The most noticeable topic for electrical engineering is power quality in recent year. The use of sensitive electronic equipment has increased now a day which has lead to power quality problems. Like voltage sag, voltage swell, harmonics, transient etc. Dynamic voltage restorer (DVR) is a custom power device used for the Compensation of voltage sag and swell. In this paper an overview of DVR, its components, functions, compensating strategies and control methods are reviewed in detail and the compensating strategies are compared.
