提出了一种基于发电机虚拟转矩和转子磁链直接控制的双馈感应发电机风力发电系统并网控制策略。这种控制没有比例积分调节器，只需要测量电网电压、转子电流和转子位置。相同的切换表用于网格同步和运行进程。开发了一种基于现场可编程门阵列的控制设计，并在一台4kW的实验样机上进行了测试。实验结果表明，所提出的快速软并网方法是有效的。
This paper presents a grid-connection control strategy of doubly fed induction generator wind system based on the direct control of both a virtual torque and rotor flux of the generator. This control is achieved with no proportional-integral regulator and requires the measurement of only grid voltages, rotor currents, and rotor position. The same switching table is used for grid synchronization and for running process. A field-programmable-gate-array-based design of the proposed control is developed and tested on a 4-kW experimental prototype. Experimental results are provided to show the effectiveness of the fast and soft grid-connection method developed.
