摘　　要：提出双馈异步发电机(DFIG)的比例谐振(PR)控制策略,实现双馈风力发电系统的空载并网控制。该方法将转子有功电流和无功电流分量转换到静止坐标系下进行调节,实现双馈风力发电系统的电网同步控制。与DFIG空载并网控制策略相比,提出的控制策略减少了坐标变换的次数,避免采用受发电机参数影响的前馈补偿控制,从而简化了控制算法,提高了控制系统的鲁棒性。实验结果表明,提出的控制策略可有效实现DFIG的电网同步控制。The proportional resonant（PR） control strategy of doubly-fed induction generator（DFIG） is proposed to realize the control of the idle load grid connection of the double-fed wind power generation system.The active and reactive current components are transformed in the stationary frame to adjust and achieve power grid synchronization control of the doubly-fed wind power system.Compared with traditional network synchronization control of DFIG,the proposed scheme reduces the times of rotating coordinates transformation,cancels the feed-forward compensation control influenced by generator parameters.The control algorithm is thus simplified and the robustness of control system is improved.Experimental results show that the proposed control strategy realizes the network synchronization control of DFIG effectively.
