大型电厂长距离输水工程设计中的几个问题探讨

Discussion on long-distance water diversion projects in large-scale power plants

大型电厂长距离输水工程的设计对整个电厂的供水安全、使用寿命及工程投资均有较大影响,文章对工程输水方式、管材管径的确定及事故工况下水量的保证等问题进行了探讨,并提出了经济管径计算公式及事故工况下连通管保证率计算公式,供同类工程设计参考。

Design of long-distance water diversion project in large-scale power plant observably influences the water supplying safety,project life and investment of the whole power plant.This paper discusses the way of water diversion,the determination of pipe material and diameter and the assurance of water quantity under accident condition,and proposes formulae of calculating the economic diameter and connecting pipe guaranteed rate under accident condition,which provide refence for similar engineering design.
