为了使热力系统易于用计算机语言表示, 实现热力系统的图形化建模和热力系统运行方式的动态改动及热力系统的自动扩展, 采用了一种全新的方法来研究大型火电机组的热力系统, 即流体网络法。它利用电网络成熟的理论来分析热力系统, 将整个热力系统类比为流体网络。首先定义了网络图的矩阵表示, 证明了简单图的关联矩阵T的秩Rank(T)为v 1, 并对热力系统的流体网络图进行了分析, 获得热力系统流体网络有向图的关联矩阵。然后利用热力系统有向图的关联矩阵, 导出了热力系统的质量平衡方程和能量平衡方程, 综合质量平衡方程和能量平衡方程导出了热力系统流体网络法的特征矩阵方程。最后基于流体网络法的特征矩阵方程提出了流体网络法的工程解决方案, 并利用实例计算结果验证了本方法的正确。
In order to make the thermodynamic system easy to represent in computer language, to realize the dynamic modeling of the thermodynamic system and the dynamic changes of the thermodynamic system operation and the automatic expansion of the thermodynamic system, a new method is used to study the thermodynamic system of large-scale thermal power units Fluid Network Act. It uses the theory of electric network maturity to analyze the thermodynamic system and the entire thermodynamic system as a fluid network. Firstly, the matrix representation of the network graph is defined, and the Rank Rank (T) of the correlation matrix T of the simple graph is proved to be v 1. The fluid network diagram of the thermodynamic system is analyzed and the correlation matrix of the thermodynamic system fluid network digraph is obtained. . Then, using the correlation matrix of the thermodynamic system directed graph, the mass balance equation and the energy balance equation of the thermodynamic system are deduced. The characteristic matrix equation of the fluid network method of the thermodynamic system is derived by the mass balance equation and the energy balance equation. Finally, based on the characteristic matrix equation of the fluid network method, the engineering solution of the fluid network method is proposed. The calculation results of the examples prove that the method is correct.
