在决定正常高水位以及进行水能调节计算时,梯级水庫有效容积的确定是有很大意义的。水库的有效容积系由其面积及所采用的消落深度决定的。由此,在梯级中上游水库的消落深度就影响到所有下游水电站的发电量,因为梯级水庫中所消落水 The determination of effective volume of cascade reservoirs is of great significance in determining the normal high water level and in the calculation of water energy regulation. The effective volume of a reservoir is determined by its area and the depth at which it will fall. As a result, the depth of upstream reservoirs in the cascade affects the amount of electricity generated by all downstream hydropower stations because of the descending water in the cascade reservoirs
