摘要
工程设计中,水电站压力管道的管径序列必须满足调节保证水击压力允许值的约束条件,本文叙述水击约束条件下压力管道管径序列优化的动态规划法.同时对不考虑水击约束条件时地下埋管的管径序列优化问题作了简要说明.文中建议的方法对其他类型的水电站压力管道也适用,该法除可供通常设计采用外.尤其适宜在水电站压力管道CAD系统中应用.
A dynamic programming procedure determining the optimal decision policy of diameter sequences of buried penstocks of hydroplants is introduced in this paper. The penstock diameter sequences must satisfy the restraint from water-hammer pressures. While there is no reasonable method to solve this optimization problem. So, the calculation of optimal decision of diameter sequences under the water-hammer restrained condition is mainly discussed, which may be suited to all types of penstocks. The optimization procedure without considering the abovementioued restrained condition is also presented. The present method can particularly be used in penstock CAD systems to improve the design.
