MITIGATION OF VOLTAGE SAG IN INDUSTRIAL GRID BY USING DYNAMIC VOLTAGE RESTORER

Abstract

Anstract - The voltage changes in a short period of concave voltage can cause serious consequences such as stop at some important load, affecting the normal operation of the entire plant. The Dynamic Voltage Recovery (DVR) is built on the basis of the modified power electronics with features to mitigate voltage changes on the concave grid to protect sensitive loads above. This paper presents the design procedure details the configuration and capacity of the installation location for a DVR. Model simulations in the Matlap-Simulink. Building empirical models with a capacity of 5 kVA DVR in the laboratory. The simulation results and experimental designs confirm the exact DVR, as a basis for practical application of DVR..
