摘　　要：从基本物理规律出发,采用面向对象的模块化建模思想,提出了一种简单的针对热动力系统中热工流体网络的建模方法。该方法通过模块的搭接来构筑和求解网络整体模型,提高了模型的开放性和可扩展性;使用差分方程解算流体网络,在精确性满足需要的同时,简化了仿真程序的编写,提高了建模效率;适用于各类常见的可压缩或不可压缩热工流体网络,具有较好的精确性、实时性和工程实用性。A simple modeling method of fluid network in thermo-power systems was brought forward based on object-oriented module modeling theory. By the linkage of different types of module units, the applicability and expansibility of holistic network mode were improved. Implicit-Euler algorithm was used to solve equations, which simplified the writing of simulative programs and enhanced modeling efficiency. This simulation method is characteristic of preferable accuracy, real-time character and actual practicability, and it can be used in the commonly compressible/uncompressible fluid-network modeling.
