摘要
本文从能量的角度出发,分析了双馈电机的运行特性和能量转换特性,从原理上证明了实现其功率控制的可行性,并给出了由双馈电机作能量转换部件的变速恒频抽水蓄能系统,建立了定子磁场定向矢量控制模型,通过控制转子电流,以实现系统的变速恒频运行和对系统有功功率和无功功率的独立控制。
This paper demonstrates the feasibility of realizing Variable Speed Constant Frequency(VSCF) operation and power control of doubly fed induction machine. A new vector control model based on the stator flux linkage reference frame is presented and the control scheme to realize independent control of active and reactive power is proposed.
