摘　　要：目的合理设计和优化管理长距离输水系统,提高长距离输水管线的安全可靠性.方法通过建立管线动态水力工况模拟系统,对管线各种运行工况进行数值模拟,并将其结果应用到管线的安全调度和运行管理中.结果对管线进行动态水力工况模拟,可使管线运行时水压分布合理;运行条件改变或发生事故时水力工况能平稳过渡,实现管线各种工况的最优化运行,确保管线安全输水结论建立了动态水力工况模拟,可实现长距离输水的科学管理,保证输水系统安全运行.In order to carry out reasonable design and the optimized management of long-distance water transmission pipeline, this paper proposes a dynamic simulation system to conduct the numerical simulation on various operating conditions of the water transmission pipeline, and to apply the results of simulation to the control and operation of the pipeline. As a result, reasonable pressure distribution in the water transmission pipeline system can be achieved during actual operation. Furthermore, a smooth transition of the pipeline operation condition also can be realized in case of the operation conditions being changed or accidents, which ensures the safe and optimum operation of the pipeline system. Consequently, in order to increase the security and reliability of long-distance water transmission system, it is very important and indispensable to construct a dynamic simulation model.
