| 摘要: |
| 全尺寸风电地面试验平台传动系统中柔性薄壁筒环节会给被测机组引入原本不存在的扭转动态影响，为此提出一种改进的风机模拟控制方法消除其影响。该改进模拟方法以被测机组主轴输入端转矩及转速与实际风机运行情况保持一致为原则，基于参考轴系模型与地面试验平台轴系模型的差异性，推导试验平台拖动电机参考转速信号，并分析了所提方法的可行性及其在不依赖微分求取上的优势；针对实际25 MW级风电地面试验平台采取的转子共轴双拖动电机方案，设计了所提方法的双拖动电机主从驱动控制策略；针对改进模拟方法所需试验平台轴系关键参数，提出一种基于模型参考自适应系统的试验平台传动轴等效刚度辨识方法。基于MATLAB/Simulink仿真验证了所提方法的有效性，仿真结果表明其能够准确还原被测机组的扭转动态，并能适应不同柔性薄壁筒刚度的需求。 |

| Abstract: |
| Flexible thin-walled cylinder link of the transmission system of the full-size wind power ground test platform will introduce torsional dynamic effects that do not originally exist to the tested unit. Therefore, an improved wind turbine simulation control method is proposed to eliminate its effects. The improved simulation method is based on the principle that the torque and speed at the input end of the main shaft of the tested unit are consistent with the actual operation of the wind turbine. Based on the difference between the reference shaft system model and the shaft system model of the ground test platform, the reference speed signal of the test platform’s driving motor is derived, and the feasibility of the proposed method and its advantage of not relying on differential calculation are analyzed. Aiming at the rotor coaxial dual-motor drive scheme adopted in the actual 25 MW-level wind power ground test platform, a master-slave drive control strategy for the dual-motors is designed. Based on model reference adaptive system, an identification method of equivalent stiffness for the test bench drive shaft is proposed to improve the key parameters of the test bench shaft system required for the improved simulation method. The effectiveness of the proposed method is verified through MATLAB/Simulink simulation. The simulative results show that it can accurately reproduce the torsional dynamics of the tested unit and can adapt to the requirements of different stiffness of the flexible thin-walled cylinder. |
