[Abstract]:The Tian Shan Yellow River Irrigation District is located in Pingyin County, Jinan City and Feicheng City, Tai'an City. It was founded in 1968 and put into operation in 1971. The irrigation district system was optimized and operated efficiently for the industrial irrigation of irrigation district, Jinan City and Feicheng City. Ecological water use and urban life are of great significance. In this paper, the water and sediment movement, the economic operation of pumping station and the efficient joint dispatch of sluices in the west sediment sink of irrigation district are studied. The main contents of this study are as follows: (1) the topographic survey and water and sediment observation experiments of sediment basin are carried out, and the topographic survey data of sediment basin channel are obtained, the velocity and sediment content data of four important sections under two different discharge rates are measured, and the velocity distribution is analyzed. The sediment content changes along the pond, and the sediment content out of the reservoir is calculated, which verifies the accuracy of the experimental data and studies the characteristics and sediment control of the sediment sink. The present situation of the sediment sink and the sediment grain gradation of the Yellow River are analyzed. By using MIKE21 software, the sediment model of sediment sink is established, and the simulation results and critical sediment discharge under several typical discharge are obtained. The scheme of sediment control for further reducing sediment content is discussed, and the simulation analysis is made on the scheme of setting the bottom sill. In this paper, the author puts forward the suitable technology measures to improve the efficiency of the pumping station and reduce the energy consumption, and puts forward the research algorithm for the economic operation of the pump station suitable for the Tianshan Electric Irrigation Station, which is suitable for the economic operation of the first class pumping station in the irrigation district, and puts forward the technical measures to improve the efficiency of the pumping station and reduce the energy consumption. The mathematical model of the economic operation of the first-grade pump station in Tian Shan irrigation district is established by using the simulation technique method. The economic operation scheme is studied. In the unsteady operation stage, the safety of water supply is taken as the limiting condition, and the efficiency of water conveyance, sediment control and pumping station is taken as the goal. Taking the control sluice of the connected project as an example, the design flow rate is calculated, and the joint dispatching analysis of the complex system of Tian Shan diversion from the Yellow River is carried out, and the high efficient joint dispatching scheme of the system is given to ensure the pumping station and the sediment sink reservoir. Using computer technology to integrate engineering information, real-time water regime, dispatching scheme and other information, the guide manual for optimal operation of the Yellow River diversion system in Tian Shan irrigation district is compiled, and the Tian Shan Yellow River diversion dispatching management information system is developed. To provide intuitive, accurate information service and technical support for Tian Shan irrigation system efficient dispatching management.
