| 摘 要： | 基于变速恒频双馈风力发电系统能实现最大风能追踪,首先建立了双馈感应发电机的三阶数学模型,在基于定子磁链定向的转子励磁控制策略基础上,提出在最大风能追踪的过程中,采用速度模式控制的系统动态特性优于采用电流模式控制的动态特性,并给出了状态空间解释.最后给出了仿真波形,仿真结果验证了分析的正确性.

| Abstract: | The doubly fed induction generator(DFIG) used in variable-speed constant-frequency (VSCF) wind energy generation system can realize the maximal wind energy capture.A model of DFIG is established firstly. Based on the stator flux-oriented excitation vector control strategy, it is shown that the system dynamic characteristics under speed-mode control are superior to the dynamic characteristics under current-mode control in the process of maximum power point tracking (MPPT);and the explanation is given based on state space theory.Finally,the simulation results in MATLAB/Simulink are put forward to verify the good static and dynamic performances of the designed closed-loop control system. |
