Voltage Quality Improvement Using Dynamic Voltage Restorer (DVR)

Abstract

Voltage sags and swells are well-known problems with serious consequences for sensitive loads. Custom power devices are utilized to solve this problem. One of them is the Dynamic Voltage Restorer (DVR) is one of these devices. One of the most efficient and effective bespoke power systems available today. In electricity distribution networks, these are the equipment that are employed. This is a paper about DVR fundamentals and voltage correction methods are discussed for voltage sags and swells in a balanced and/or unbalanced system of distribution The results of the simulation were presented to Analyze and comprehend DVR's performance under circumstances of voltage sags/swells The outcomes of the research The efficiency of the method was proved by simulation using MATLAB. This gadget is particularly effective in compensating voltage sags and swells (relative to voltage sag/swell duration) Quick reaction.
