| 摘 要： | 本文基于某长引水式水电站水力过渡过程的数值模拟,针对蜗壳末端压力受涌浪压力控制的情况,进行压力管道直径的优化。结论表明,减小压力管道直径将导致蜗壳末端水锤压力增加,控制其最大值不超过涌浪压力控制值,可在一定范围内缩小压力管道直径,减少工程投资,对类似工程具有一定的参考意义。

| Abstract: | Based on the numerical simulation of the hydraulic transition process of a hydropower station with long diversion system，the diameter of the penstock is optimized in accordance with status that the pressure at the end of the spiral case is under the control of the surging pressure. The conclusion shows that reducing the diameter of the penstock can lead to the increase of the water-hammer pressure at the end of the spiral case，and then if its maximum value is only controlled to be not over the control value of the surging pressure，the diameter of the penstock can be reduced within a certain range for saving the project investment. This has certain reference significance for the similar projects concerned. |
