| 摘 要： | 根据双馈发电机的数学模型,在强迫定向的定子磁场控制策略的基础上,改造DFIG励磁变频器控制策略,实现孤岛下双馈风机恒压恒频运行。技术思路:通过调节转子磁场旋转频率控制定子电压频率,调节转子磁通幅值控制电机内电势。控制转换开关,使得双馈风机孤岛下借助蓄电池进行起励,之后投入直流电容并退除蓄电池,实现双馈风机孤岛恒压恒频运行。并利用Matlab/Simulink对所提出的方案进行了仿真,结果表明该方案的可行性。

| Abstract: | From the beginning of mathematics model of doubly fed generator, the excitation control for stand-alone doubly fed generator was remade that based on forced stator-flux-oriented control strategy, ensure that the stand-alone doubly fed generator work properly at constant voltage constant frequency(CVCF) operation. Technical ideas: Control the frequency of stator voltage by adjusting the rotating frequency of the rotor magnetic field. Adjust the rotor flux amplitude for controlling the stator internal potential. By controlling the switches, ensure the stand-alone doubly fed generator running by itself at CVCF operation. A model was build that simulated in the Matlab/Simulink, the results show that the control strategy is feasible. |
