集中供热网的可及性分析

Accessibility analysis of district heating networks

针对集中供热网，尤其是多热源环形网提出了可及性分析的概念，建立了相应的数学模型并探讨了用混合遗传算法求解的方法。通过所编制的相应软件对国内几个大型集中供热网的分析研究结果表明，在环形网上合理地装配和调节阀门，有利于改善系统的工况，充分利用管网的输送能力，提高运行的经济性。给出了一个具体的算例。

Presents the concept of accessibility analysis for heating networks especially for the multi heat sources and multi loops system, describes a mathematical model for the analysis and its solution based on a mixed generic algorithm. With a software developed in the basis of the algorithm such analyses of several large heating networks reveals that proper installation and regulation of valves in the pipework is conducive to improvement of the operation conditions and utilization of the deliverability. Gives an example of using the procedure.
