Abstract :

Compensation of load side voltage design and implementation of a topology of Dynamic Voltage Restorer with Embedded Z- source Inverter which is capable of compensating voltage sag and voltage swell at sensitive load terminals. Depend on this; the DVR consists of uncontrolled rectifier for giving DC supply to Embedded Z source inverter through DC link. This topology is proposed in order to improve the voltage restoration property in high voltage transmission line. By controlling the over shoot through EZI provide ride-through capability during voltage sag, swell and high reliability. With the help of hysteresis controller the restored voltage will be injected in line. The simulation results are presented to manifest the effectiveness of the proposed DVR system, which exhibits the compensation for voltage sag and swell mitigation.
