| 摘 要： | 由于双馈感应发电机(DFIG)的传统控制策略在电网电压不对称跌落下的控制性能较差,提出了一种基于抑制转子侧负序电流的控制策略,以提高DFIG在电网电压发生不对称跌落的控制性能.在不对称跌落下,该控制策略可对DFIG的转子电流的正、负序分量同时进行控制,使用MATLAB/Simulink建立仿真模型,仿真结果表明此控制策...

| Abstract: | Because the control strategy of double fed induction generator under asymmetic drop in grid voltage very poor.Raise a control strategy of rotor-side converter based on negative sequence current,To enhance the control performance of DFIG under asymmetic fault.Based on asymmetic dips,This control strategy can control positive negative sequence of rotor current on the same time,Use MATLAB/Simulink build simulation model,The result shows that this control strategy can improve the operating performance of DFIG under asymmetic grid voltage dips. |
