Implementation of Dynamic Voltage Restorer in Distribution System

Dhivya. T

Abstract: Power quality is one of the major concerns in the era of power system. Power quality problem occurred due to non- standard voltage, current or frequency, that result in a failure of end user equipment. To overcome this problem, Dynamic Voltage Restorer (DVR) is used, which eliminate voltage sag, swell and during fault in the distribution line, it is efficient and effective power electronic device. The size of DVR is small, cost is low and fast dynamic response to the disturbance. By injecting an appropriate voltage, the DVR restores a voltage waveform and ensures constant load voltage. The compensating signals are determined dynamically based on the difference between desired and measured values. The DVR is consisting of VSC, Booster transformer, Filter and Energy storage devices. This paper used for compensate the voltage sag, voltage swell and during three phase fault of the distribution line.
