摘　　要：针对变速抽水蓄能机组有功功率与转速之间的协调控制问题,分析了变速抽水蓄能机组有功功率与转速协调控制原理,提出了变速抽水蓄能机组有功功率与转速协调控制方法,并搭建了变速抽水蓄能机组控制系统联合RTDS仿真试验平台,对变速抽水蓄能机组有功功率与转速协调控制方法进行了联合仿真试验验证。试验结果表明:发电工况有功功率与转速协调控制宜采用交流励磁系统转速闭环和调速器有功功率闭环控制方式,抽水工况有功功率与转速协调控制宜采用交流励磁系统转速闭环和调速器开度闭环方式。For the problem of coordinated control between active power and speed of variable-speed pumped-storage unit,the coordinated control principle between active power and speed is analyzed,and the coordinated control method is proposed.The RTDS simulation test platform for the control system of variable-speed pumped-storage unit is built,and the coordinated control method between active power and speed is verified.The test results show that the AC excitation speed closed-loop and governor active power closed-loop mode should be adopted for the active power and speed coordinated control under generating condition,and the AC excitation speed closed-loop and governor opening closed-loop mode should be adopted for the active power and speed coordinated control under pumping condition.
