| 摘要: |
| 针对直驱永磁风电机组，提出低电压穿越(LVRT)模型参数的整定方法。基于直驱永磁风电机组的通用模型结构，计算各参数的轨迹灵敏度，获得LVRT模型的关键参数。指出由于参数的非线性特性，现有的基于轨迹灵敏度的参数辨识方法难以适用。为此，提出将参数调整与参数优化相结合的参数整定方法。以某直驱永磁风电机组为例，基于实测数据进行了参数整定及模型验证，并进行了其他扰动场景下的适应性分析，结果验证了所提方法的可行性和有效性。 |

| Abstract: |
| A parameter setting method of LVRT(Low Voltage Ride-Through) model is proposed for direct drive permanent magnet wind turbine generators. The trajectory sensitivity of each parameter is calculated based on the universal model structure of direct drive permanent magnet wind turbine generator and the key parameters of LVRT model are obtained. It is pointed out that the existing parameter identification methods based on trajectory sensitivity are difficult to be applied because of the nonlinear characteristics of parameters. Therefore, a parameter setting method combined with parameter adjustment and parameter optimization is proposed. The parameter setting and model verification are taken out based on the measured data of a direct drive permanent magnet wind turbine generator and the adaptability under other disturbance scenarios is analyzed. The results verify the feasibility and effectiveness of the proposed method. |
