Voltage Boosting and Restitution of Voltage Sag by making use of DVR

Divya Anwekar | Amit Gupta ^[9]

Abstract: The dynamic voltage restorer is one of the power electronic based device. It is also known as the custom power device which is used in the distribution system. It is used for the protection of household and industrial electrical devices against sudden changes in the amplitude of voltage, mainly voltage sag and voltage swells. The DVR works in such a manner by injecting the compensating voltage to the system where the disturbance or fault has occurred DVR can inject up to 50 % o the nominal voltage to the system. In this paper, the analysis on DVR is done, and also its functions are explained. Simulation results are also being shown and compared to each other to find out and examine the capability and usefulness of the controlled structure.
