　　由于双馈机组已成为国内主流机型且大型双馈机组风电场通常占地面积比较大，需要研究双馈风电机组间的尾流效应及时滞对双馈机组风电场的并网点输出特性的影响情况。通过搭建了30台2 MW双馈风电机组组成的风电场模型，对风速波动和电网故障下双馈机组风电场输出特性进行分析和比较。通过仿真表明，机组间的尾流效应导致双馈机组风电场的风能损失；风速时滞平缓了风电场输出功率。

Because doubly fed induction generator has become the mainstream type and a large wind power plant usually covers a larger area,the impacts of wake effects among wind turbines and time delay on output characteristics of wind power plant need to be studied. With a wind power plant model composed of thirty 2?MW double fed induction generator wind tur?bines,the output characteristic of wind power plant under the conditions of wind speed fluctuation and grid faults is analyzed and compared. The simulation results show that the wake effects among wind turbines can cause the wind energy loss of wind farm and the wind speed time delay will smooth the power output of wind farm;wake effects among wind turbines and wind speed time delays needs to be considered when the grid?connection stability of wind farms with double fed induction generator wind turbines is analyzed.
