摘　　要：论文介绍了风电系统中双馈风力发电机(DFIG)的工作原理,论文中所提出的双馈风力发电系统主要采用了双PWM换流器结构的交流励磁系统。并运用矢量控制的控制策略对网侧变换器和励磁侧变换器进行控制。并通过Matlab软件构建了最大风能追踪的仿真模型对其进行仿真,仿真表明论文中所提出的控制策略能够实现现风力发电系统的最大风能追踪和对双馈风力发电机有功功率和无功功率实现独立调节。This paper introduces the operation principle of doubly-fed wind power induction generator（DFIG）,in this paper proposed a doubly-fed wind power generation system which is mainly a dual PWM converter structure of AC excitation system.And the vector control strategies is used in the network side converter and the exciter side conver-ter. Through the Matlab software to build the biggest wind power track model makes the simulation.The consequence show that the control strategy can achieve the largest wind energy wind power generation system to track and double-fed wind generator active and reactive power are regulated independently.
