  Simulation of Dynamic Voltage Restorer for Voltage Sag Mitigation

  By G S Gayathri, K Manimala

  Abstract: In recent years, power quality is the major issue in transmission and distribution network. This paper concentrates on one of the power quality problem, such as voltage sag. A novel mitigation system is simulated using Dynamic voltage restorer (DVR). The proposed system is boosting the sagged phase voltage by deriving the voltages from other healthy phases. The system is designed with two ac chopper circuits and two transformers. The voltage …
