摘要
风电场内部尾流相互作用影响下游风力发电机组的流入风速,为了降低尾流效应对漂浮式风电场发电量的影响,提出了考虑尾流效应的漂浮式风电场偏航优化控制策略。针对偏航状况下尾流恢复速度变化以及对下游机组尾流影响的特殊性,建立高斯卷曲混合尾流模型。考虑偏航工况对叶片位移、叶根载荷以及平台运动的影响,设定机组偏航角范围为约束条件,利用连续最小二乘(SLSQP)优化算法,以整场发电量最大为目标函数,偏航角为优化变量,优化获得风电场内每台机组最优偏航角以及各台机组发电量。仿真结果表明,所提控制策略可有效提高风电场整场发电量。
The interaction of internal wakes in wind farms affects the inflow wind speed of downstream wind turbines.To reduce the impact of wake effects on the power generation of floating wind farms,a yaw optimization control strategy of floating wind farms considering wake effects is proposed.A Gaussian curl mixed wake model is established for the specificities of the wake recovery speed changes and the impact on the wake of downstream units under yaw conditions.Considering the influence of yaw conditions on the blade displacement,the blade root load,and platform motion,a range of unit yaw angles is set as a constraint condition.Using the least squares SLSQP optimization algorithm,the optimal yaw angle and power generation of each unit in the wind farm are obtained with the maximum overall power generation as the objective function and the yaw angle as the optimization variable.The simulation results show that the proposed control strategy can effectively improve the overall power generation of the wind farm.
