| 摘 要： | 避免双馈风力发电机转子侧过电流的出现是确保转子侧变流器的安全运行的重要措施。通过对双馈电机的空载数学模型以及空载时定向坐标系与定子、转子坐标系间的位置关系分析,提出了基于虚拟电网磁链观测基础上的电流前反馈解耦控制的转子电流闭环控制策略。相关仿真研究验证了所提出的控制策略的正确性和有效性。 |

| Abstract: | To prevent overcurrent occuring at the rotor side of doubly-fed induction generator (DFIG is an important way to ensure the safe operation of rotor-side converter. Analyzing the no-load mathematical model of DFIG and the relatonship of its vector coordinate system with the stator and rotor coordinate systems, and according to the virtual grid flux estimation, this paper proposes a closed-loop control strategy for the rotor current, namely the forward feedback decoupling control. The correctness and effectiveness of the proposed strategy has been verified through related simulations. |
| Keywords: | doubly-fed induction generator (DFIG) wind power rotor current control |
