%X 上游风电机组的尾迹对下游风电机组会产生较为明显的影响。该文基于自由涡尾迹方法，结合几何精确梁方法，分析了上下游风电机组的耦合响应。分析结果显示，即使是在6倍叶轮直径处，下游风电机组仍然受到上游尾迹影响，叶轮功率会大幅下降，而叶片载荷波动会大幅上升。而将叶轮偏置一个叶轮直径后，并不能明显地降低上游尾迹影响。<br>The wind turbines in the wind farm are easy to be affected by wakes of upstream wind turbines. In this study, a FSI model based on nonlinear geometrically exact beam (GEB) and a free-vortex wake (FVW) model are applied to study coupled responses under wake effect. As a result, to the downstream wind turbine, the rotor power will decrease and while the load fluctuation of rotor blades will increase, even when the distance between upstream and downstream wind turbines is 6 rotor diameters. After one rotor diameter offset, the load fluctuation cannot decrease significantly
