| 摘 要： | 建立了考虑蒸汽温位因素的全局能量集成超结构,描述了在全局热源、公用工程、汽轮机、全局热阱之间进行热量传递和交换的所有可能的拓扑结构。基于此超结构,建立了全局能量集成的混合整数非线性规划模型,并用列队竞争算法进行求解。通过优化求解,得到高压、中压和低压蒸汽的优化温位和流量,使全局能量集成更有效。实例表明:本文所提出的方法优于没考虑蒸汽温位因素的全局能量集成。

| Abstract: | A super structure for total site energy integration is established considering steam level factors,where all possible topology of heat transfer and exchange among site heat sources,utility system,steam and site heat sinks,are described.Based on the super structure,a mixed integer non-linear programming(MINLP) model is established for total site energy integration.Steam levels and flow rates of high pressure(HP),middle pressure(MP) and low pressure(LP) are obtained by solving the model using line-up competit... |
