摘　　要：降低风电场尾流效应可以有效提高风电场的整体发电量,偏航尾流优化控制成为近年来风电领域的研究热点。本文提出了一种考虑推力载荷的风电场偏航尾流优化方法,它以偏航角和轴向诱导因子为优化参数,实现了最大化总功率输出和最小化机组推力载荷的协同优化。以25台风电机组规则排布的风电场为研究对象,研究了不同入流风向及湍流强度下的尾流优化效果。结果表明,考虑推力的偏航尾流控制优化模型存在最佳平衡参数,能够在实现风电机组推力载荷减小的同时,使风电场的总功率输出提高1.96%。Reducing the wind farm wake flow effect can effectively improve the overall power generation of wind farms,and the optimized control of yaw wake flow as become a research hotspot in the field of wind power in recent years.In this paper,a yaw wake optimization method for wind farms considering thrust load is proposed,which takes the yaw angle and axial induction factor as the optimization parameters,and achieves the synergistic optimization of maximizing the overall power output and minimizing the thrust load of the units.Taking a wind farm with 25 units in regular rows as the research object,the effect of wake flow optimization under different incoming wind directions and turbulence intensities is investigated.The results show that there is an optimal equilibrium parameter in the optimization model of yaw wake flow control considering thrust load,which can increase the overall power output of the wind farm by 1.96%while reducing the thrust load of the wind turbines.
