摘　　要：为了对大型多热源环状供热管网快速地水力计算,文中结合某市供热环网的案例,在已知有限个节点流量和热源流量的情况下,提出了一种基于水力计算软件的水力计算方法,基于图论建立热网拓扑结构进行水力计算的方法进行了比较分析,为大型多热源环状管网快速水力计算提供了借鉴。This paper presents a limited number of node flows and heat source flows to quickly perform hydraulic calculation of a large multi-heat source ring-shaped heating pipe network. The hydraulic calculation method is compared with the method of hydraulic calculation based on graph theory to establish a heat network topology structure, which provides a reference for fast hydraulic calculation of large-scale multi-heat source annular pipe network.
