Abstract :
The paper studies a practical project of 2 MVA dynamic voltage restorer on the basis of transformer-less cascade multilevel topology, it discusses each part working principle of DVR, but also provides a practical voltage sag problem solving scheme for a 6 kV feed line based on proposed cascade structure. EMTDC/PSCAD based simulation results verify the validity of proposed scheme
