摘要
为研究基于主动偏航控制下的尾流效应对风力机运行特性和尾流特征的影响,模拟时考虑背景湍流入流,设置2台串列排布的NREL-5MW风力机,对上游风力机实施主动偏航控制并改变2台风力机间的间距,基于动态尾流蜿蜒模型协同风力机运行控制,定量研究不同间距下采取主动偏航控制的2台风力机的运行特性和尾流特征。研究结果表明:2台风力机间的间距会影响最大输出功率和上游风力机的最优偏航角;上游风力机的偏航控制对2台风力机总输出功率的增益随着间距的变化呈现出不同的规律;相比无偏航情况,对上游风力机施加主动偏航控制后,下游风力机在上游风力机的倾斜尾流作用下,其尾流也呈现出轻微的不对称特征,且尾流膨胀率减小。
In order to investigate the influence of wake effect based on active yaw control on wind turbine operation characteristics and wake features,two tandem NREL-5 MW wind turbines are set up to implement active yaw control on the upstream wind turbine and to change the spacing between two wind turbines.Based on the dynamic wake meandering model and wind turbine operation control,the operation characteristics and wake features of two wind turbines with active yaw control at different spacing are quantitatively studied.The results show that the spacing between two wind turbines affects the maximum power output and the optimal yaw angle of the upstream wind turbine.The yaw control of the upstream wind turbine has different rules for increasing the total power output of two wind turbines as the spacing changes.Compared with the case without yaw,after active yaw control is applied to the upstream wind turbine,the wake of the downstream wind turbine also exhibits a slight asymmetry under the influence of the wake deflection of the upstream wind turbine,and the wake expansion rate decreases.
