摘要

The Pressure-Node Model is used in the simulation of single-phase incompressible fluidlcompressible fluid system.When the pressure nodes are dense or the differential pressure is lesser between nodes,this model will cause problems,such as unbalanced flux in all the branches of one node,slow calculating,and so on so forth.This article will introduce a Liyuid-Network Model that is based on random topology network.This model made a great improvement on the flux channels modeling method.1t calculates and analyzes not ony one node but all the nodes inside the flux network.The mathematical models of the draft fan and air heater and all kinds of flow resistance mathematical models such as pressure flux branch are built on the analysis of super-critical boiler air flue system.The simulation arithmetic of the air flue system is developed by modulating and it was simulated on Simpanel for the static state and dynamic characteristic.The research discussed in this article has been applied to full conditions simulation system of a 600MW unit and got good result.
