摘　　要：针对国内目前没有交流励磁的运行案例,交流励磁的控制技术的研究就显得尤为必要和紧迫。设计了一套交流励磁三电平变频器动模系统,针对影响系统运行性能的LCL滤波器和直流平波电容进行了深入的设计分析,给出动模设计方法,并对所设计的滤波器和电容进行了仿真和动模验证。验证结果显示,该设计方法是可行的。There is no practical operation case of AC-excitation variable-speed pumped-storage unit in China at present, it＇s particularly necessary and urgent to research the control technology of AC-excitation. A set of AC-exeitation three-level inverter dynamic simulation system is designed and the designs of LCL filter and DC smoothing capacitor which affect system performance are analyzed. The design method of dynamic simulation system is proposed. The designed LCL filter and DC smoothing capacitor are simulated and verified by the dynamic simulation system. The result shows that the design method is feasible.
