| Abstract: |
| 【Objective】The optimal scheduling method of "two reservoirs and three pumping stations" irrigation system in hilly areas was studied.【Method】Aiming at the problem of joint operation of two reservoirs and three pumping stations in drought years in hilly areas, the optimal scheduling model of "two reservoirs and three pumping stations" irrigation system was constructed. the objective function was to take the minimum sum of squares of irrigation water shortages in each irrigation area and each period, and the constraints included the annual water supply of the system, the annual water supply of the pumping station, the water lifting capacity of the pumping station, and the optimal scheduling criteria of the reservoir, etc. The large system decomposition-coordination method based on experimental optimization was used to solve the optimal scheduling scheme.【Result】Taking the joint optimal operation of Shanhu Reservoir and Niqiao Reservoir in Liuhe District of Nanjing City, Jiangsu Province in dry years as an example, the result showed that compared with the conventional scheduling scheme of preferred parameters, the irrigation water shortage in Niqiao Irrigation District was reduced from 350,000 m3 to 00,000 m3, the amount of abandoned water in Shanhu Reservoir was reduced from 450,000 m3 to 00,000 m3, the amount of extracted river water was increased from 4.03 million m3 to 4.35 million m3, and the terminated water storage of Shanhu Reservoir and Niqiao Reservoir was increased from 8.19 million and 1.45 million m3 to 8.47 million and 1.59 million m3 of initial water storage.【Conclusion】The large system decomposition-coordination method based on experimental optimization is used to solve the optimal scheduling scheme, which can effectively reduce the amount of abandoned water in the reservoir and increase the amount of irrigation water supply. It can also give full play to the water lifting capacity of the pumping station and reduce the number of water lifting of the pumping station. In addition, it can also meet the requirements for the specific value of the terminal water storage of the reservoir. |
