基于拓扑复杂程度的实际供热管网建模方法研究与分析
摘要：提出了按照管网拓扑复杂程度建立水力工况仿真模型的思路，以及结合流量方向和最小闭合差判断环网水力交汇位置的方法。以某市区集中供热管网为研究对象，根据3种复杂程度建立管网水力工况仿真模型，并取3种工况验证分析。结果表明，该方法能准确判断环网水力交汇位置，每一级的模型仿真压力与实际值的最大相对误差的绝对值均低于10%,且管网拓扑结构复杂程度越高，模型模拟误差越小，建模成本越高。

Research and analysis on modeling method of actual heating network based on topology complexity
Abstract: In this paper, a simulation model of the hydraulic condition is established according to the complexity of the network topology, and a method is proposed to judge the hydraulic intersection location of the ring network by combining the flow direction and the minimum closure difference. Taking the central heating network in an urban area as the research object, the hydraulic condition simulation model of the network is established according to three kinds of complexity, and verified with three kinds of conditions. The results show that the method can accurately judge the hydraulic intersection location of the ring network, and the absolute value of the maximum relative error between the model simulation pressure and the actual value of each stage is less than 10%. Moreover, the higher the topology complexity of the network, the smaller the model simulation error, and the higher the modeling cost.
Keywords: central heating; topology; heating network; complexity; simulation modeling; hydraulic intersection; pressure balance of ring network;
