摘　　要：作为风电并网主流机型——双馈风电机组的并网控制日益重要,然而传统矢量控制的双馈风电并网控制,其转子位置角信号容易受到干扰而影响其稳定性,给风电并网带来了影响。分析了双馈风电机组(DFIG)的同步化特点,提出了基于转子电压幅值和频率控制(MFC)的DFIG并网控制方法,并进一步提出了基于MFC控制的含调度指令功能的DFIG并网控制策略;通过仿真验证了基于转子电压MFC的双馈风电并网控制策略的有效性。As a major type of wind power generation unit,DFIG（Doubly-Fed Induction Generator） grid-connected control becomes increasingly important.However,based on the traditional vector control,the stability of the DFIG system is affected because the rotor angular signal measurement is vulnerable to disturbance.In this study,synchronous characteristics of DFIG were analyzed.Then,a grid-connected control of the DFIG was proposed based on the rotor voltage magnitude and frequency control（MFC）.Besides,a grid-connected DFIG control with dispatched command function was also presented based on the MFC.The Simulation results show the effectiveness of the rotor voltage amplitude and frequency control（MFC） strategy.
