摘    要:在大型水利水电工程中 ,管道系统结构复杂 ,而且包含各种非管道元件 ,在该类系统的仿真中初值计算通用性很差 ,影响了系统仿真的自动建模。该文基于管网的恒定流计算方法 ,同时考虑各种非管道元件的特性 ,提出一种新的包括各种非管道元件在内的管网计算方法——虚拟阻抗法 ,解决了初值计算通用性差的困难。该方法适合各种复杂的管道系统布置 ,计算结果合理 ,使大型水利水电系统仿真的自动建模得以真正实现

关 键 词:仿真  管网  自动建模  水电工程

Abstract:Large hydraulic engineering has complex pipe networks and many nonpipe elements. It is very difficult to build a general program to calculate the steadystate heads and flows at the inner points of the pipes and in the nonpipe elements of the system for automatic modeling in a system simulation. Based on the pipe network computation, a new method (virtual resistance method) is presented to solve this problem, which takes into account the resistance effect of some nonpipe elements. This method can be applied to different hydraulic engineering projects without reprogramming and provides the foundation for automatic modeling in the large hydraulic engineering simulation.
Keywords:simulation  pipe networks  automatic modeling  hydraulic engineering
