**ABSTRACT:**In this paper, the operation of DVR is presented and the control technique used for voltage source inverter is Space vector PWM. Space vector PWM techniques can utilize the better dc voltage and generates the fewer harmonic in inverter output voltage. Phase jump compensation is achieved by using Phase Locked Loop. This work describes the DVR based on Space Vector PWM incorporating the PLL provides voltage support to sensitive loads and is simulated by using MATLAB/SIMULINK. The control approach presented is able to compensate for any type of voltage sags and swells. This work also intended to assimilate the amount of DC energy storage depends on the installed load.Computer Communication and Informatics (ICCCI), 2013 International Conference on; 01/2013 -
##### Conference Paper: Mitigating voltage sags due to DOL starting of three phase asynchronous motors using dynamic voltage restorer (DVR)

**ABSTRACT:**Voltage sags caused by starting large asynchronous motors, especially in industrial distribution system have huge impacts on system power quality. The paper analyses and proposes an extended application of custom power devices using dynamic voltage restorer for mitigating voltage sags due to the direct-on-line (DOL) starting of asynchronous motors in industrial distribution system. In the paper, different control strategies used for custom power devices are analyzed and an effective method is proposed. A test system is simulated in Matlab/Simulink with different DVR configurations that proves the effectiveness and robustness of the proposed control strategy with dynamic voltage restorer for voltage sag mitigation. The results show that voltage sags are totally compensated.Transmission and Distribution Conference and Exposition (T&D), 2012 IEEE PES; 01/2012 -
