Mitigation of Voltage Sag using DVR

  • Abstract:
  • Voltage Sag and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problem based on recent power quality studies. Their impact on sensitive loads is serve. The impact ranges from load disruptions to substantial economic losses up to millions of dollars. Different solutions have been developed to protect sensitive loads against such disturbance but the DVR considered to be the most efficient and effective solution. Its appeal includes lower cost, smaller size and its dynamic response to the disturbance. In this paper, an enhance voltage sag compensation strategy is proposed, which mitigates the phase jump in the load voltage while improving overall sag compensation time. An analytical study shows that the proposed method significantly increases the DVR sag support time (more than 50%) compared with the existing phase jump compensation methods.
