摘　　要：目前风力发电行业的价格竞争日趋激烈,在保证机组安全的情况下降低机组成本成为行业当前的重要任务,而降低整机载荷是一种有效降低整机设计成本的方法。为了有效降低机组载荷,文章基于激光雷达设计了风机辅助控制算法。针对正常发电工况设计了基于激光雷达测风的前馈控制,该控制算法能有效降低风机塔底My疲劳载荷约9.36%;针对极端湍流工况设计了湍流控制算法,该控制算法能有效降低机组在极端湍流工况下叶根Mxy极限载荷约4%;针对风速风向极端变化工况设计了阵风控制算法,该算法能有效降低机组在阵风工况下塔底Mxy极限载荷约15%、静止轮毂Myz极限载荷约12%、偏航Mxy极限载荷约15%。仿真结果表明,本文所提控制算法能有效降低风机关键零部件载荷。Amid the intensifying price competition in wind power generation,cost reduction has become the top priority currently in the industry,on the premise of ensuring turbine safety.Reducing loads on wind turbines is considered an effective method to lower design costs.To effectively reduce load,this paper presents the design of a series of LiDAR-based assisted control algorithms.A feedforward control algorithm based on LiDAR wind measurement is designed for normal power generation conditions,aiming to at effectively reduce the fatigue load of the tower base My by about 9.36%.A turbulence control algorithm is designed for extreme turbulence conditions,which can effectively reduce the ultimate load of the blade root Mxy by about 4%.Moreover,a gust control algorithm is designed for conditions with extreme changes in wind speed and direction,leading to effective reductions in the ultimate load of the tower base Mxy by about 15%,the stationary hub Myz by about 12%,and the yaw system Mxy by about 15%.The simulation results demonstrated the effectiveness of these LiDAR-based control algorithm.
