This　paper　investigates　the　impact　of　doubly-fed　induction　generator　(DFIG)　wind　farms　on　system　stability　in　multi-generator　power　systems　with　low-frequency　oscillations　(LFOs).　To　this　end,　this　paper　establishes　the　interconnection　model　of　the　equivalent　generators　and　derives　the　system　state　equation.　On　this　basis,　an　updated　system　state　equation　of　the　new　power　system　with　integrated　wind　power　is　further　derived.　Then,　according　to　the　updated　system　state　equation,　the　impact　factors　that　cause　changes　in　the　system　damping　characteristics　are　presented.　The　IEEE　two-area　four-machine　power　system　is　used　as　a　simulation　model　in　which　the　LFOs　occur.　The　simulation　results　demonstrate　that　the　connection　of　wind　power　to　the　power　feeding　area　(PFA)　increases　the　damping　ratio　of　the　dominant　mode　of　inter-area　oscillation　from　-0.0263　to　-0.0107,　which　obviously　improves　the　system　stability.　Furthermore,　the　wind　power　integration　into　PFA,　as　the　connection　distance　of　the　wind　power　increases,　gradually　decreases　the　damping　ratio　of　the　dominant　mode　of　the　inter-area　oscillation　to　-0.0236,　approaching　that　of　no　wind　power　in　the　system.　Meanwhile,　with　the　increase　in　the　wind　power　output　capacity,　the　damping　ratio　of　the　dominant　mode　of　the　intra-area　and　inter-area　oscillation　increases,　and　the　maximum　damping　ratios　reach　0.1337　and　0.0233,　respectively.
