| 摘要: |
| 为了实现一整套开放、可扩展的风力发电实验平台，分析了双馈电机的工作原理，推导了其在空载并网过程和并网后变速恒频以及最大功率跟踪的控制策略。首次推导并采用了定子磁链定向下的转速外环和无功功率内环的双闭环控制结构来实现并网后的控制要求，并在Simulink环境下仿真验证了控制策略的效果。研制了以TMS320F28335和PLC为核心的全开放式实验平台，DSP程序实现了控制策略。实验波形和结果证明了模型和控制策略的有效性，以及该实验平台的可扩展性和稳定性。 |

| Abstract: |
| To realize a whole set of wind power experimental platform that is both fully-open and extensible, the principles of doubly-fed induction generator (DFIG) are analyzed. The controlling strategies of gird-connection and variable-speed- constant-frequency (VSCF) and maximum-power-point-tracking are derived, and the structure of rotating speed external loop and reactive power inner loop under stator flux orientation is applied. The effects of the controlling strategies are examined in Simulink environment. A full-open experimental platform is developed based on the digital signal processing (DSP) chip of TMS320F28335 and PLC. Controlling strategies of DFIG are implemented by DSP program. The experiment results verify the validity and efficiency of the model and the controlling strategies and the stability of the platform. |
