摘　　要：针对抽水蓄能电站交流励磁可变速机组的黑启动,提出了一种黑启动交流励磁装置,对其结构、各部分功能及主要设备参数计算方法进行了分析讨论,提出了与之适应的黑启动交流励磁控制方法。针对实际控制中励磁电源切换过程可能出现的冲击问题,提出了参数设定判据。构建了包括交流励磁控制装置实物及RTDS的实时仿真系统,对黑启动过程进行了仿真研究。仿真结果表明,本文提出的黑启动交流励磁装置及其控制方法可实现变速机组母线电压的平稳、快速建立,同时各中间电气量变化平稳。A kind of black-start AC excitation device is proposed for the black start of variable speed pumped-storage unit.The structure,the function of each part and the calculation method of main equipment parameters of the black-start AC excitation device are analyzed and discussed,and the corresponding control method of the black-start AC excitation device is also proposed.The parameter setting criterion is proposed to deal with the possible shock problem during the excitation power switching process in actual control.A real-time simulation system including the AC excitation control device and RTDS is built for simulation study of black start process.The simulation results show that the proposed black-start AC excitation device and its control method can realize the stable and fast establishment of bus voltage of variable speed unit,and the intermediate electrical quantities change smoothly at the same time.
