针对多热源环状热网故障工况的模拟问题，提出了一种空间热网的拓扑重构方法。该方法基于图论理论，首先搜索隔离故障点所需关闭的阀门，只关闭故障点所在的供水或回水管上的阀门，充分利用了环状管网的备用功能；然后给出停热的管段和热用户，并对故障工况管网进行拓扑重构。编制了计算机程序，通过算例分析表明，该方法能很好地解决故障工况非对称热网的模拟问题，算法适用于各种型式的热网，收敛速度快、模拟精度高。

Aiming at simulation problems for multi-heat source ring-shaped heat-supply network under fault conditions,presents the reconstruction method of topology structure of spatial heat-supply network, which is based on the graph theory,first searches the valves needed to be shut for insulation fault repair and only shuts the valves on the water supply pipe or return pipe of fault repair to utilize adequately standby function of ring-shaped heat-supply network,then affords the pipe segment and heat users to stop supply and puts up topology reconstruction under fault conditions.Develops a computer program,and the analysis on an example indicates that the method can commendably solve the simulation problem of dissymmetrical heat-supply network under fault conditions,which arithmetic is suitable for various types of heat-supply network with rapid convergence rate and high simulation precision.
