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.
