死水位(dead storage level)是指:水库在正常运用情况下的最低水位。正常蓄水位与死水位之间的高差,称为水库消落深度。死水位应通过综合技术经济比较和分析选定。其原则是:(1)使水电站的保证出力和年发电量在既定的正常蓄水位条件下接近最大值;(2)考虑防洪及其他综合用水部门如灌溉、航运等对水库最低水位的要求;(3)要注意低水位时水轮机运 Dead storage level (dead storage level) refers to: the reservoir in the normal use of the lowest water level. The difference between the normal water level and the dead water level is called the depth of the reservoir. Dead water level should be selected by comprehensive technical and economic comparison and analysis. The principle is: (1) make the guaranteed output of hydropower stations and annual power generation close to the maximum under the established normal water level conditions; (2) consider the minimum water level requirements of flood control and other integrated water resources departments such as irrigation and shipping ; (3) pay attention to low water level when the turbine transport
