摘　　要：针对海上风电场疲劳载荷分布不均衡、各机组维护频次不同步而导致运维成本高的问题,提出了一种考虑疲劳载荷分布的海上风电机组出力优化控制策略。基于风机最小推力系数控制策略有效降低风电场的尾流效应,以疲劳载荷分布均衡为目标优化各机组的疲劳载荷,使各机组维护频次同步,进而降低运维成本。仿真结果表明:与风机最大功率点跟踪控制策略相比,所提策略在实现风电场疲劳载荷均衡分布的同时,使得风电场年发电量提高4.20%。To address the problem of unbalanced fatigue load distribution in offshore wind farms and high O&M costs due to the unsynchronized maintenance frequency of each unit,an optimal control strategy for offshore wind turbine output considering fatigue load distribution is proposed,which effectively reduces the wake effect of wind farms based on the minimum thrust coefficient control of wind turbines,optimizes the fatigue load of each unit with the goal of balanced fatigue load distribution,synchronizes the maintenance frequency of each unit,and thus reduces costs.The simulation results show that compared with the maximum power point tracking control strategy,the proposed strategy achieves a balanced distribution of fatigue load on the wind farm while increasing the annual output of the wind farm by 4.20%.
