【摘要】 交流励磁发电机又称双馈感应发电机(DFIG)。通过调节发电机转子绕组励磁电流的频率、幅值和相位即可实现变速恒频运行。通过对交流励磁发电机动态数学模型的研究,提出了基于定子磁场定向的矢量控制策略。并进行了有功和无功功率独立调节的仿真实验,仿真结果验证了控制策略的正确性。更多还原

【Abstract】 AC excitation generator is also called doubly fed induction generator.The control of variable speed constant frequency (VSCF) is im- plemented by controlling the frequency,amplitude,phase angle of the rotor winding excitation currents of the machine.By analyzing the dynamic mathematical model of the AC excitation generator,the vector control strategy of active and reactive power is provided.The result of the simulation verifies the validity of the proposed strategy.更多还原
