中文摘要：

针对水电站长引水道系统机组导叶的关闭规律,根据涌浪压力及水锤压力的不同性质,提出了合理统筹调压室断面面积、阻抗孔口尺寸、关闭时间三者的优化方案.同时指出在可研阶段优化导叶关闭规律存在较多的不确定性因素,还应结合关闭规律的敏感性分析以得到一个鲁棒性较好的关闭规律.

英文摘要：

According to different properties of surging pressure and water hammer pressure, relationship among of area of surge tank, size of throttling orifice and closure time should be taken into account during optimization of vane closure law in the long-distance convey tunnel system. The optimization scheme that consider the three factors simultaneously is designed. In addition, during the stage of designing many uncertainty factors exist in the optimization of vane closure law. The vaue closure law with good robust can be obtained using sensitive analysis of vane closure low.
