Dunhuang　wind　farm　in　Gansu　province,　China　with　237　GW　wind　energy　potential　has　a　great　significance　for　northwest　grid　in　China.　In　this　paper,　in　line　with　Hexi　750kV　Power　Transmission　Line　Protections　project,　modeling　of　different　wind　turbines　are　studied.　In　this　research,　modeling　and　analysis　of　doubly　fed　induction　generator　for　wind　turbine　applications　is　investigated.　Based　on　the　vector　control　method,　the　simulation　is　executed　in　PSCAD/EMTDC　software　and　the　results　show　the　performance　of　the　system.　The　data　are　used　based　on　the　real　information　from　the　wind　farm　site.　Also,　the　smart　grid　roadmap　is　considered　for　this　wind　farm　to　adjust　itself　with　new　situations　hence　smartening　the　grid.　Furthermore,　fault　analysis　and　stability　of　the　system　can　be　feasible.
