Abstract
This letter proposes a novel sag detection method for the line-interactive dynamic voltage restorer (DVR). The DVR with proposed detection method can compensate the voltage sag or interruption within 2-ms delay, which is faster than the existing delay time of 4 ms. The feasibility of proposed method was verified through computer simulations. The DVR with proposed detection method can effectively compensate the voltage sag or interruption for sensitive loads.
