复杂空间热网的拓扑结构及水力过程仿真

针对多热源多环复杂热网的水力过程，提出了基于空间管网的计算方法。该方法可根据网络的固有参数通过求解非线性方程组给出不同工况下管网的流量分配和节点压力，还可解决故障导致的管网水力不对称问题，从而弥补了平面网方法的不足。应用图论理论描述了空间热网的拓扑结构，提出了用平面网信息生成空间网络关联矩阵和基本回路矩阵的实用方法。编制了计算程序，通过算例验证了该方法的正确性和实用性。

Topology and Simulation of Complex Spatial Heating Network

Based on spatial network, a new calculation method is put forward for simulating the hydrodynamic course of multi-heat sources and multi-loops complex heating network. The method can calculate flux assignment and node pressure of heating network under different conditions by counting non-linear equation group according to network inherent parameter, solve the calculation problem of asymmetric network as the result of fault and remedy the shortcoming of the method for planar network. The topology of spatial heating network is described with graph theory, and an applied method for creating relating matrix and basic loop matrix of spatial network is put forward according to information of planar network. The correctness and practicability of the method are validated by an example.
