Abstract：As the wind power penetration from large scale wind turbines, which are based on variable speed constant frequency (VSCF) doubly fed induction generators (DFIG), has been increasing rapidly in the transmission system, the grid codes for grid connected wind turbines evolve continuously and demand that the wind power generator has to ride through the grid faults, especially the grid voltage dips. In this paper, the influence of grid voltage dips on the DFIG is analyzed firstly. Meanwhile, the control objective of the low voltage ride through (LVRT) is proposed. Several types of LVRT technology for the DFIG wind turbine systems are then summarized and evaluated respectively. Finally, for the purpose of revealing the latest progress and the developing direction of this technology a valuable conclusion about the optimizing of the LVRT technology is drawn from the above discussion.
