摘　　要：地下厂房机组安装高程不仅取决于水轮机的吸出高 ,而且取决于水电站水力过渡过程有关的参数 ,甚至对导叶关闭规律的优化、洞室间距的确定、以及调压井型式和尺寸的选取有着重要的影响。本文在阐明上述关系的基础上 ,从水轮机的基本理论和工程实际出发 ,提出地下厂房机组安装高程设计的基本思路和具体步骤 。The installation elevation of turbine is not only dependent on the suction height of turbine, but also decided by large transient conditions in underground power station. Whether heigh or low, the installation elevation will give effect to the optimization of wicket operation rule, to the decision of underground structures interval, and to the selection of surge tank type and size. The paper has analysed these interactions, suggested the design procedure for the installation elevation of turbine, and applied the procedure to the design of two large underground power stations.
