摘要/Abstract

摘要： 以高水头抽水蓄能电站引水支管长度作为优化设计目标，进行敏感性分析，找出水力过渡过程计算中同时满足蜗壳进口最大压力计算控制值和尾水管进口最小压力计算控制值时的引水支管长度合理取值范围。研究结果表明：JFS 及 DLH 抽水蓄能电站工程中的压力值随引水支管长度的变化有相同的变化趋势，且水力过渡过程计算值均能满足规范的计算控制值要求时，引水支管长度可变范围均处在上游调压井到球阀前长度的 6.5%~7.8%。

Abstract: To optimize the length of the penstock branch of a high-head pumped storage power station, sensitivity analysis is conducted to determine the reasonable range of penstock branch length where the hydraulic transient process calculation values can simultaneously satisfy the maximum pressure at the spiral case inlet and the minimum pressure at the draft tube inlet. The study results show that the pressure values of JFS and DLH pumped storage power stations exhibit the same trend with the change of the penstock branch length. When the hydraulic transient process calculation values meet the code-specified control values, the variable range of the penstock branch length is between 6.5%~7.8%of the length from the upstream surge tank to the ball valve.

Key words: hydraulic transient process calculation, penstock branch length, sensitivity analysis, pressure at the spiral case inlet, pressure at the draft tube inlet
