摘　　要：明渠输水是大型调水工程的常用手段,其运行控制的目标状态由恒定流解法求得,其调节过渡过程的稳态却由非恒定流数值解法得到,两者之间的差异直接影响系统控制的精度以及过渡过程时间。以南水北调工程为仿真背景,定量分析两者的差异及形成机理,并且对这一差异在系统控制中的影响进行分析。Canal flow is the most common method for water delivery, the target state is calculated by steady flow method, but the steady state of operating procedure is simulated by the unsteady flow method, the difference between two solutions will greatly influence the accuracy of control and transition time. Based on the South-to-North Water Transfer Project, the thesis quantitatively analyses the difference and its influence to the control of system.
