| 摘 要： | 通过对风力机简化模型的分析,推导出风力机的运动方程和输出方程;通过卡尔曼坐标变换将塔架前后运动方程和载荷输出方程所代表的线性时变系统解耦为线性时不变系统,在此基础上提出带3个独立控制环的独立变桨控制策略;利用"GH Bladed"软件对独立变桨控制策略进行仿真试验研究,仿真试验结果表明,采用独立变桨控制技术不但能实现转速控制功能,还能有效减小叶片根部挥舞力矩、轮毂倾翻力矩、偏航力矩的波动,从而能有效降低变桨轴承、主轴、轮毂、偏航轴承、塔架上的疲劳载荷。

| Abstract: | Based on the analysis of simple wind turbines model,the motion equations for the drivetrain and output equation were deduced.The time-varying system that depends on the blade azimuth angles was transformed to a purely time-invariant linear system using the Coleman transform.And an individual pitch control strategy that composed of three individual control loops was put forward.Simulation study of the individual pitch control strategy using GH Bladed software was developed.The simulation verifies result show... |
