中文摘要	南水北调中线工程引汉总干渠自动控制和安全运行是南水北调工程的重大课题。现提出"双参数等容积—限流量控制模式"作为总干渠运行自动控制方式。首先,以渠段中点水位不变来保持该渠段内水体容积V0不变即静态参数等容积控制;其次,以渠段水力坡度J不超过上限值J0来控制渠水断面流量即动态参数限流量控制;利用上述控制达到全干渠流量实时动态平衡控制。建议采用"精密气泡式水位计"作为自动控制的测量仪器,对控制误差作了估算。; Autocontrol and safe operation of the general diversion channel from Han River in the South-to-North Water Transfer Project are important tasks.Dual-parameter of equal water volume & limit discharge control model for the general channel operation autocontrol model has to be presented in this paper.First,the water level at the middle point of the channel section should not be changed to keep equal water volume V0 of this channel section,i.e.realizing the equal water volume control through static parameter.Next,the energy gradient of the channel section J should not be exceed the limit energy gradient J0 to control the discharge of the channel section,i.e.realizing the limit discharge control through dynamics parameter.The real-time dynamic balance discharge control of the whole general channel is to be got by using the dual-parameters autocontrol model.The Precision Bubbles Water Level Gage is recommended as a measuring instrument for the autocontrol process.The error of autocontrol has to be estimated in the paper.
