| Abstract: |
| The large-scale self-pressing tree-shaped irrigation pipe network has the characteristics of high difference and long distance. Several pressure regulating tanks are arranged at appropriate positions of the pipe network system to ensure the safe operation of the irrigation pipe network and reduce the total investment. In this paper, pressure regulating tank and the main pipe network are taken as a whole, and the method of synchronous optimization of the pressure tank arrangement and the pipe diameter combination is proposed. The double coding method based on integer coding is adopted, and the sum of the cost of the main pipe and the cost of pressure regulating tank is used. The minimum is the objective function, with the constraint of pressure and pipe flow rate, and the related mathematical model is established. The genetic algorithm is used to solve the problem, and the optimization of pressure regulating tank arrangement and the optimization of the pipe diameter are realized simultaneously. Comparing the optimization scheme with the artificial experience method, the results show that the working pressure of the main pipe water distribution node is more balanced, the total length of the main pipe is reduced by 12.02%, and the total investment of the system is reduced by 17.23%, indicating that the method can obtain better self-pressure tree irrigation. The layout scheme of the pipe network pressure regulating tank provides a reference for the pipe network arrangement with similar terrain conditions. |
