基于节能低碳的管网优化研究

应用全生命周期法分析供水管网不同管材组合的各阶段能耗,为兼顾经济性和低碳降耗,建立供水管网的能耗函数与管网经济性函数耦合组成多目标优化函数.采用C++平台智能遗传算法对供水管网多目标优化函数进行求解.最后以某城市局部区域的管网为实例进行模型实际应用,计算结果能够在保证经济性的基础上兼顾管网全生命周期的能耗以及管网的供水安全,较好地与实际相吻合.

Network optimization research based on energy conservation and low carbon

The whole life cycle method is used to analyze the issue of water supply network energy consumption of each stage of different pipe combination. For giving to consideration to both economy and low carbon consumption, the new multi-objective optimization function including water supply network energy function and economy function is built. Besides, genetic algorithm based on C＋＋ is used to solve multi-objective function. Finally taking the water supply network of part area of a certain city as an example as shown in the results, this model can not only guarantee the economy but be considered the lifecycle of the network energy consumption and pipe network of water supply security well in conformity with the actualities.
