摘　　要：对大功率双馈风力发电机网侧变流器并网方式进行研究,充分利用了双馈风力发电机网侧变流器的数学模型及适时的分段加入各控制环方法来实现该控制方案,详细地描述了其并网策略,并且利用PSIM对所提出的策略进行了仿真,并通过实验验证该方案的正确性,仿真和实验结果都表明所提出的策略具有良好的过渡过程和动态性能。A new control strategy of the grid-connected converter in the system of the doubly-fed wind turbine was presented. Operation process of this grid-connected control strategy was detailed, the mathematical model of the grid-side converter and timely control loop entry were employed to complete the new control strategy. While PSIM was employed to simulate the proposal, through experiment ,to verify the correctness of the control strategy. The experimental results show the control strategy has a good transition process and the dynamic performance.
