长距离明渠输水工程实时控制研究

Real Time Control of Water Stage in Long Distance Open Channel Water Convegance

介绍等水位、等容量水位实时控制原理，给出了数学模型．运用该原理，可以对长距离明渠输水工程水位进行实时控制．这种控制方法应变能力强，可控范围大；能节约工程投资，缩短工程周期，便于实现运行管理的全自动化．最后进行了模型试验验证．

The real time control principle for flow stage in open channel according to the constant stage and constant volume method is described in this paper,and numerical models are given too.Computational and test results show that the present controlling method is distinct from other methods in its good adaptability to different discharges and stages,its sensitivity to various disturbances,and its simple device reguirement.This method can help save the projeat cost,shorten the constrution period and realize the automatic operation management along the channel.
