The high-frequency resonance in the superstructure of a pumped storage power station (PSPP) due to the generation unit can shorten the service life of the power station structure and even endanger its safety. Although tuned mass dampers (TMDs) have been proved to be effective in controlling structural vibration, their application in PSPPs is rare, as high-frequency vibration control of PSPPs has not been studied. In this paper, a TMD control method is proposed based on PSPP high-frequency vibration and various TMD control strategies, and a set of high-frequency TMD equipment is designed. Results of a series of vibration reduction tests and numerical analyses show that the new TMD device can effectively control the high-order mode of the structure, and the bandwidth of the suppression frequency is extended, which shows the robustness and control efficiency of the device.

基于多重TMD的抽水蓄能电站的结构振动控制

发电单元在抽水蓄能电站（PSPP）上部结构中产生的高频共振会缩短电站结构的使用寿命，甚至危及其安全性。尽管已证明调谐质量阻尼器（TMD）可有效控制结构振动，但由于尚未研究PSPP的高频振动控制，因此它们在PSPP中的应用很少。提出了一种基于PSPP高频振动和多种TMD控制策略的TMD控制方法，并设计了一套高频TMD设备。一系列减振测试和数值分析结果表明，新型TMD器件可以有效地控制结构的高阶模态，并且抑制频率的带宽得到了扩展，
