Designing and Modeling of Dynamic Voltage Restorers for Power Quality Control in Myanmar Info-Tech Zar Zar Tun Voltage sags and swells in the medium and low voltage distribution grid are considered the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. Different solutions have been developed to protect loads sensitive against such disturbances. Among them, DVR is considered to be the most efficient and effective solution. Its appeal includes loner cost, smaller size and its dynamic response to the disturbance. This paper described DVR principles and voltage restoration methods for balanced and/or unbalanced voltage sags and swells in a distribution system. DVR is a powerful custom power device useful for short duration voltage compensation of sensitive loads against voltage disturbances in power distribution lines. The presentation will focus on the technical market requirements and the proposed solution for Myanmar Info-Tech, which is the largest computer and software industry in Myanmar. Myanmar Info-Tech is often encountering power quality problems including voltage sag/swell and short interruption. To overcome these problems, the DVR solution is introduced in this paper with Matlab simulation . 2009 http://hdl.handle.net/20.500.12678/0000001963 https://meral.edu.mm/records/1963
