| 摘 要： | 针对双馈变速恒频风力发电机组控制并网和功率控制问题，采用转子磁链直接转矩控制方法，调节转子侧交流励磁，达到控制双馈发电机定子侧输出的目的。通过控制基理研究，制定控制实验框图，并在30kW机组试验平台上验证，得到机组同步化过程中和并网前后的实验结果。经测试、分析，此控制策略有效，可以在同类发电机组中推广应用。

| Abstract: | To solve the connection to the grid and power control problems of Doubly-Fed Variable Speed Constant Frequency(VSCF)wind turbine control system,the method of rotor magnetic flux Direct Torque Control(DTC)was used to regulate rotor side AC exciting,and get the aim of controlling stator side output.The control principle was described,the trial control scheme was established,and the performance was verified by a 30kW wind turbine trial platform.The trial results of control strategy were obtained on the process of synchronization and before and after getting connected to the grid.By testing and analyzing,the validity of the control method is confirmed,which can be popularized to other similar generator system. |
