节制闸联合调度控制下明渠输水系统水力控制研究

A Study of Hydraulic Control of the Open Channel Water Diversion System under Combined Control of all Check Sluices

本文对明渠输水系统下节制闸联合控制中的同步控制法和顺序控制法进行研究,对不同控制方法下长距离明渠输水系统在增流量和减流量工况下的各闸闸前水位、闸后水位、水力过渡时间等水力特性进行了分析比较。研究结果显示,当流量增大时,易采用提前顺序控制方法;当下游渠段流量因意外情况需要立即减少时,易采用同步控制方法。

This paper deals with the synchronous control method and the sequential method in the combined control of check sluices under the open channel water diversion system.Hydraulic behaviors of water level before and after the check sluices and water hydraulic transfer time of long-distance open-channel water diversion system under different control methods,and in the close of industrial operation conditions with discharge increase and decrease are analyzed and compared.The research results indicate that when the discharge is increased,the sequential method in advance should be used and that when the discharge in the downstream section needs to be reduced immediately in the case of emergence,the synchronous control method is adopted.
