基于PSO算法的中型灌区输水调度模型研究
|
摘要
本文建立了基于PSO算法的灌区输水调度模型,并选取了两个典型的渠道灌溉系统(位山灌区、小开河灌区)对模型进行了验证。结果表明:该算法稳健高效,能够快速满足渠道灌溉系统的输水优化调度。与常规求解方法相比,该模型将两个灌区选定的渠段输水渗漏损失量分别降低了25.93%和16.83%,有效提高了渠道灌溉系统的输水效率,干渠输水量接近实际水量,所提出的模型及优化求解算法可为灌区提供实用高效的输水调度方案。
An irrigation area water dispatching model based on a PSO algorithm is established in the paper. Two typical channel irrigation systems(located in Weishan irrigation area and Xiaokaihe irrigation area)are selected to verify the model. The results show that the algorithm is robust and efficient,which can quickly meet the optimal dispatching of canal irrigation systems. The leakage loss of water in the selected canal sections of the two irrigation areas are respectively reduced by 25.93% and 16.83% through the model compared with the conventional solution method. The proposed model and optimization solution algorithm can provide a practical and efficient water dispatching plan for the irrigation area.
