摘　　要：对抽水蓄能电站尾水调压室的设计规范进行了探讨,结合可逆机组的实际运行情况与工程算例,研究了关闭规律、运行工况、输水系统布置方案以及压力脉动对尾水管内最小负压的影响,得到的相关结论可供抽水蓄能电站输水系统设计参考。The specifications for design of tailrace surge chamber at pumped storage plant are discussed in this paper, and the influence of wicket gate closing law, operactional regime layout of water conveyance system and pulsating pressure on the minimum negative pressure in draft tube is studied in connection with the actual operational and engineering calculating example of pumped storage plant. The beneficial conclusions which can be referenced for the design of other pumped storage plant water conveyance system are obtained.
