Mitigation of Voltage Sags and Swells by Dynamic Voltage Restorer

Abstract:

This paper presents the modelling and simulation of Dynamic Voltage Restorer (DVR) for mitigation of voltage sags and swells which are the major problems and issues on non linear loads.The Dynamic Voltage Restore (DVR) has become popular as a cost effective solutions for the protection of sensitive loads from voltage sags and swells.. The control of compensation voltages in DVR based on a-b-c to d-q-0 algorithm is discussed. The proposed control technique is cost effective and simple to design. Computer simulations are carried out in a suitable test system to investigate the effectiveness of control technique by using MATLAB/SIMULINK software.
