由于大型风电场占地面积较大，风电机组数量众多，风电机组间尾流效应和风速时滞将对风电场产生一定的影响。采用 Weibull分布函数，建立随机风速模型和风电机组模型，构建含风速场模型的风电场小干扰稳定模型。仿真分析复杂风速场下的风电场运行情况、对线型分布和交叉分布的三风机系统，得到了不同分布方式下系统的特征根变化轨迹，发现尾流效应和时滞效应对风电场机网小信号稳定的影响较小，通过合理的风机分布可以增加风电场的稳定裕度。

Because of the large scale wind farms occupied a larger area,and containing a large number of wind turbines,wake effects and wind delay among wind turbines have a certain impact on wind farms.Based on Weibull distribution function,the stochastic wind model and wind tur-bine mathematical model of wind farm were established in this paper.The small signal stability model of wind farm was created,and the complex wind farms operation was comprehensively an-alyzed.The linear-distribution and cross-distribution of three fan system were simulated,and the changing of eigen-values under different distribution methods was analyzed.It was found out that wake effects and the time-delay have little influence to small signal stability.The stability margin of wind farms via reasonable distribution of fans can thus be increased.
