摘　　要：针对传统抽水蓄能系统所采用的同步水轮机组效率低、转速适应能力弱的情况,设计了一种基于双馈方式的抽水蓄能系统。通过分析双馈电机数学模型,采用基于定子磁链定向的矢量控制方法,提出基于转子侧变流器的双馈电机零速自起动控制策略,对机组的零速起动及同步并网过渡过程进行了仿真和实验研究。仿真实验结果表明,该系统在由零速起动至同步并网的整个过程,转速变化平稳,定、转子电流波动小,且控制简单,运行可靠,有较高的实用价值。According to the features of the traditional synchronous hydro- generator being inefficient and little adaptable to revolution,a pumped storage system based on doubly- fed method was presented. With the analysis of the mathematical model of doubly- fed induction generator,adopting a stator flux oriented vector control method,the zero- velocity starting control strategy based on rotor converter was proposed,and the process of zero- velocity starting to network synchronization was listed. Simulation and experiment results show that the changing process of rotor speed is stabilized,the stator current and rotor current are stabilized for starting and network synchronization,moreover,this control method is comparatively easy,reliable and has high practical value.
