摘　　要：变速抽水蓄能技术是未来抽水蓄能发展的方向,合理的控制策略是充分发挥变速抽水蓄能机组技术优势的关键。本文在对变速抽水蓄能机组整体建模的基础上,提出了一种转子动能转移自适应控制策略,建立了包含变速抽水蓄能机组及常规火电机组的电力系统模型,对不同运行工况下系统的频率调节能力进行仿真。结果表明,本文提出的控制策略能更加有效的帮助机组释放或吸收转子动能,使得系统负荷突变时,系统频率上升或下降波动程度更小,有效提升变速抽水蓄能机组参与系统调节的能力。Variable speed pumped storage technology is the direction of future pumped storage development,and a reasonable control strategy is the key to fully leveraging the technological advantages of variable speed pumped storage units.Based on the overall modeling of variable speed pumped storage units,this article proposes a rotor kinetic energy transfer adaptive control strategy,establishes a power system model including variable speed pumped storage units and conventional thermal power units,and simulates the frequency regulation ability of the system under different operating conditions.The results show that the control strategy proposed in this article can more effectively help the unit release or absorb rotor kinetic energy,so that when the system load suddenly changes,the fluctuation degree of system frequency rise or fall is smaller,effectively improving the ability of variable speed pumped storage units to participate in system regulation.
