| 摘 要： | 液压型风力发电机组主传动系统为定量泵-变量马达闭式系统，风机并网后依靠变量马达变排量机构对系统进行控制。研究了系统压力控制特性，建立了并网后主传动系统数学模型,得出了系统压力对马达斜盘摆角的传递函数。利用MATLAB辨识工具箱，根据实验数据，对系统压力控制模型进行数据辨识，并与理论模型进行对比，验证了理论模型的准确性，为液压型风力发电机组通过压力控制实现最佳功率追踪控制奠定理论与实验基础。

| Abstract: | Fixed displacement pump-variable displacement motor is the main drive system of hydraulic type wind turbine, the system is controlled by a variable displacement mechanism after grid-connected. To study the pressure control characteristics, a mathematical model was built and the transfer function describing the pressure to the position of the motor swash plate was derived. Compared with the identified model obtained from data identification in MATLAB system, the built model was verified, which laid theoretical and test foundation for further maximum power point tracking(MPPT) based on pressure control in hydraulic type wind turbine. |
