摘　　要：在电力系统仿真软件中建立了双馈风电场和仿真电力系统模型,分析了双馈风电场并网后对低频振荡阻尼模式的影响,双馈风电场并网后出力变化、双馈风电场从不同位置并网对系统低频振荡模式阻尼的影响,仿真结果表明双馈风电机组接入系统后会引入新的振荡模式,随着双馈风电场出力增加,系统阻尼降低。双馈风电场从不同位置接入电网,不会改变系统的振荡模式,但是会改变系统在某些振荡模式下阻尼的性质。The doubly fed induction generator wind farm model and power system simulation model is established in the power system simulation software. The paper analyzes the influence of wind farm integration from different sites on power system low frequency oscillation damping and the change of the wind farm outputs after connecting the wind farm to grid. The simulation results show that a new oscillation mode occurs after connecting the wind farm to the grid, the system damping decreases with the increasing output of the double fed wind farm, and the damping characteristic might be changed when connecting the wind farm to the grid from different sites.
