【摘要】 为提升小开河灌区引调水管理水平，减少引调水过程的渗漏损失，以灌区干渠渗漏水损失最小兼顾全年引调水频次少为目标，构建灌区水库群引调水优化模型。采用遗传算法对模型求解，得到灌区全年内水库群引调水过程优化方案。以小开河灌区2022-2023调度年的水库群引调水过程为实例分析，结果表明，采用灌区水库群引调水优化模型制定的引调水方案，单次引调水过程最多可减少渗漏损失81.26万m~3，损失率降低4.25%，全年可减少渗漏损失313.84万m~3，损失率降低2.35%，全年引调水次数可减少3次，有效减少渗漏损失并便于灌区引调水管理。该研究构建的灌区水库群引调水优化模型可为灌区制定引调水计划提供科学支撑，指导灌区科学合理配水与集中统一调度。更多还原

【Abstract】 In order to improve the management of water diversion and transfer in Xiaokaihe Irrigation District and to minimize leakage losses during diversion, an optimization model of water diversion for reservoir groups in the irrigation district is established in this paper, with minimizing leakage loss and water diversion in the main canal and at the same time reducing the frequency of water diversion and transfer throughout the year as the main objective. A genetic algorithm is employed to solve the model, providing an optimized scheme for the yearround process of water diversion and transfer from reservoir groups in the irrigation district. Taking the 2022-2023 reservoir water diversion and transfer operations in the Xiaokaihe Irrigation District as a case study, the results demonstrate that the water diversion and transfer scheme developed through the reservoir groups optimization model for the irrigation district can reduce seepage losses by up to 812 600 m3 in a single diversion process, achieving a 4.25% reduction in the loss rate. Annually, leakage losses could be reduced by 3 138 400 m3, a 2.35% decrease in loss rate, along with a reduction of three diversion events per year, thereby significantly minimizing leakage losses and enhancing water diversion management in the irrigation district. The reservoir groups diversion optimization model developed in this study provides a scientific basis for irrigation districts to formulate water diversion and transfer plans, guiding irrigation districts in scientific and reasonable water distribution and centralised and unified scheduling.更多还原
