The　paper　presents　a　new　control　strategy　to　enhance　the　ability　of　reactive　power　support　of　a　doubly　fed　induction　generator　(DFIG)　based　wind　turbine　during　serious　voltage　dips.　The　proposed　strategy　is　an　advanced　low　voltage　ride　through　(LVRT)　control　scheme,　with　which　a　part　of　the　captured　wind　energy　during　grid　faults　is　stored　temporarily　in　the　rotor＇s　inertia　energy　and　the　remaining　energy　is　available　to　the　grid　while　the　DC-link　voltage　and　rotor　current　are　kept　below　the　dangerous　levels.　After　grid　fault　clearance,　the　control　strategy　ensures　smooth　release　of　the　rotor＇s　excessive　inertia　energy　into　the　grid.　Based　on　these　designs,　the　DFIG＇s　reactive　power　capacity　on　the　stator　and　the　grid　side　converter　is　handled　carefully　to　satisfy　the　new　grid　code　requirements　strictly.　Simulation　studies　are　presented　and　discussed.
