摘要：

风电机组间的尾流效应对发电量有直接的影响,漂浮式机组的尾流受姿态的影响导致其建模和优化更加复杂。针对漂浮式基础位移,提出了一种基于偏航控制的风电场尾流优化策略。首先,考虑漂浮式平台位移对偏航角的影响,改进了Curl尾流模型;其次,建立了风电场发电量与尾流风速、偏航角关系的目标函数;最后,以偏航角为优化参数,采用Nelder-Mead单纯形法进行优化,从整体上提高了风电场的发电量。基于NREL 5 MW的TLP型漂浮式机组,在不同工况条件下对控制策略进行仿真验证,结果表明所提优化策略较传统尾流优化方法提高漂浮式风电场整场发电量效果更加明显。

Abstract:

The wake effect between wind turbines has a direct impact on the power generation,and the modeling and optimization of the wake of floating units are more complex due to their attitude.A wind farm wake optimization strategy based on yaw control is proposed considering the floating foundation displacement.Firstly,considering the influence of floating platform displacement on yaw angle,the Curl wake model is improved.Secondly, the objective function of the relationship between wind farm power generation and wake wind speed and yaw angle is established.Finally,taking the yaw angle as the optimization parameter,optimization is carried out with the Nelder-Mead by the simplex algorithm method to improve the power generation of the wind farm as a whole.Based on NREL 5 MW TLP floating unit, the control strategy is simulated and verified under different working conditions.The results show that the proposed optimization strategy has a more obvious effect on improving the power generation of the floating wind farm than the traditional wake optimization method.

Key words: floating wind turbine, yaw control, wake optimization, power generation improvement
