摘要
滴灌系统干管设计是否合理,直接影响滴灌系统投资及运行费用,本文以滴灌系统年费用最低为目标,建立了滴灌系统管网优化模型,采用遗传算法对模型进行求解。应用结果表明:该模型及算法能够快速、准确地计算出管网优化方案及水泵优化扬程,适合滴灌系统管网的优化设计。
The design of main pipe in drip irrigation system is reasonable or not affects the investment and operation cost of drip irrigation system directly, This paper regards the irrigation system cost minimum as the goal, establishes the pipe network optimization model of drip irrigation system and uses genetic algorithm to solve the model. The application results show that the model and algorithm can calculate the optimal scheme of the pipe network and the optimal pump head quickly and accurately, which is suitable for the optimal design of the pipe network of drip irrigation system.
