摘　　要：基于交流励磁抽水蓄能机组运行特点,分别建立可逆水泵水轮机和交流励磁电机数学模型;针对可逆水泵水轮机在不同运行模式下的输出特性,分别建立水轮机工况和水泵工况下的负荷特性优化流程;结合电动和发电运行工况,提出功率由交流励磁调节,转速或导叶由可逆水泵水轮机控制的抽水蓄能机组快速功率响应控制策略。通过与传统转速励磁控制策略进行仿真比较,结果表明所提控制策略能够同时提高机组的功率响应速率和可逆水泵水轮机运行效率。Based on the operating characteristics of ACEPSU（AC Excited Pumped Storage Unit）,the models of both reversible pump turbine and AC excited machine are established.In view of the different output characteristics of reversible pump turbine,load optimization flowcharts of turbine and pump are presented.Combined with operating conditions of the motor and generator mode,a rapid power response control strategy for ACEPSU is proposed,in which the power is controlled by AC excited machine and both the rotor speed and gate are controlled by reversible pump turbine.Comparison of simulative results between the conventional and proposed strategy indicates that the proposed strategy can not only improve the power response rate of ACEPSU,but also increase the efficiency of reversible pump turbine.
