三峡五级船闸运行级数及补水判断程序

三峡五级船闸是目前世界上规模最大的通航设施，船闸投入运行的级数需根据不同，下游水位的组合来确定。本文分析推地了在满足各闸室设计允许的最高，最低通航水位及输水闸门最高工作水头条件下，根据实测的上，下游水位判断运行级数，计算补水量的方法和数学模型，解决了监控系统自动生成船闸运行级数，自动判断补水及补水量计算等问题。

Judgment Program of Operation Level Number and Complement Water for Three Gorges Five-Level Ship Lock

At present,Three Gorges five-level ship lock is the largest navigation facility in the world. The operation level number in which ship lock is put into operation, will be determined according to comination of various water levels of upstream and downstream. The article analyzes and deduces method and mathematical model that judge operation level number and calculate complement water volume according to measured water levels of upstream and downstream on the condition that satisfy the highest and the lowest navigation water levels and the highest working water head of culvert valve which are allowable for design of each lock chamber. It resolves problems such as automatic creation of the operation level number of ship lock by the supervi sory control system and automatic judgement of complement water and calculation of complement water volme.
