火力发电流体网络建模与实现

基于四方公司CyberSim通用图形化仿真建模软件,利用C++编程工具,对传统单相流体网络压力迭代计算方法进行了改进,采用流体网络拓扑和矩阵求解相结合的方法,解决了传统压力迭代模块化建模方法中无法考虑流体网络高度差或动态阻力压差影响、孤岛多解、边界和内部计算节点转换的问题,该软件已在多方项目中应用并得到肯定。

Modeling and Realization of Thermal Power Fluid Network

Based on the general graphical simulation modeling software developed by Sifang Company,C++ programming tools are used to improve the traditional single-phase fluid network pressure iterative calculation method.The method of combining the fluid network topology with matrix solution is adopted to solve the problem of not being able to consider fluid network height difference or dynamic resistance pressure influence,the island with multiple solutions and conversion problems of boundary & internal computing nodes.The software has been used in PG9171E of Jiangsu Wujiang Power Plant,V94.2 of Yizheng Power Plant,M701F4 gas turbine simulation projects of Huaneng Beijing Thermal Power Plant and gained acceptance.
