摘　　要：基于交流励磁方式的可变速抽水蓄能(VSPS)机组,因其运行方式灵活、调节速度快等特点日益受到电网的青睐。文章详细推导了采用定子磁链定向矢量控制的变速抽水蓄能交流励磁机组发电工况和抽水工况的数学模型,设计了功率闭环控制器,在实时数字仿真系统(RTDS)试验平台和对拖式异步-双馈电机物模实验平台上进行了仿真验证和实验验证。结果表明,本文设计的控制策略控制效果优良,适用于大型变速抽水蓄能交流励磁机组系统。The variable-speed pumped-storage(VSPS)units based on the AC excitation system is increasingly favored by the power grid because of its flexible operation mode,fast adjustment speed,etc.In this paper,the mathematical model of the generator operation mode and the pump operation mode of the VSPS AC excitation unit based on stator flux oriented vector control is derived in detail.The closed-loop power controller is designed,and the simulation and experimental verification is done based on the Real-Time Digital Simulation(RTDS)test platform and the coaxial motor asynchronous-double-fed motor physical model test platform.The results show that the control strategy designed in this paper has a good performance,and it’s suitable for the large-scale VSPS AC excitation system.
