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

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.
