摘　　要：可变速抽水蓄能机组由于在发电和抽水工况下,均可以实现大范围的功率调节,因此具有较好的应用前景。为了研究可变速抽水蓄能机组的稳态运行特性,本文从变速电机的旋转同步数学模型出发,深入分析定子侧功率与转子电流、转子电压之间的关系,并绘制出机组的稳态运行特性图。针对300MW机组的运行特性进行了实时数字仿真(Real Time Digital Simulation, RTDS),仿真结果验证了机组运行特性曲线的正确性,为今后大容量变速抽水蓄能机组的设计运行提供了经验。Variable speed pumped storage unit can achieve a large range of power adjustment under both generation and pumping conditions, so this kind of machine has good application prospect. In order to research the steady-state operating characteristic of variable speed pumped storage unit, this paper analyzes the relationship between the stator side power and the rotor current and rotor voltage by using the rotational synchronous model of variable speed motor(VSM). Then the steady-state operating characteristic figure is plotted. RTDS simulation of the operating characteristic of a 300 MW unit is carried out. The simulation results verified the correctness of the operating characteristic of the unit, and provided experience for the design and operation of large-capacity variable speed pumped storage unit.
