多热源环状空间热网拓扑结构研究

Topological structure of multi-heat source ring-shaped heat-supply network

提出了一种建立空间热网拓扑结构的方法,该方法在平面网络的基础上,引入热源信息矩阵和热用户信息矩阵。采用广度优先搜索生成空间热网的"树",据此构建树支关联矩阵、链支关联矩阵和基本回路矩阵。该方法为多热源环状热网的水力工况分析和非对称热网的计算提供了实现的手段。

Presents a method for establishing topological structure of spatial heat-supply network based on a plane network, and introducing the heat source information matrix and heat consuming installation information matrix. By adopting breadth-first search, makes spatial heat-supply network tree, and composes branch incidence matrix, chain incidence matrix and fundamental circuit matrix. This method affords a way to performing the calculation of multi-heat source ring-shaped heat-supply network hydrodynamic condition analysis and asymmetric heat-supply network.
