| 摘 要： | 深入分析了高水头混流可逆式水泵水轮机和球阎各自流量特性的特点，提出了在过渡过程中将导叶和球阎动作相配合的调节规律优化思路．通过对某高水头抽水蓄能电站水力过渡过程的计算分析表明，这种调节规律能大幅降低水锤压力，有效防止反“S”区的水力振荡．

| Abstract: | Based on intensive analyses of flow-across characteristics of rev er sible turbines and ball valves, a kind of optimization scheme is suggested for t he closing procedures of wicket gate and ball valve in load rejection hydraulic transient conditions,Numerical simulations of hydraulic transients in an actual pumped-storage project show that this gate-valve cooperated procedure can obse rvably reduce water hammer pressure and efficiently suppress the hydraulic oscil lation in anti-pump area. |
