城镇燃气管网优化设计系统开发及其应用

DEVELOPMENT AND APPLICATION OF OPTIMIZED DESIGN SYSTEM FOR CITY GAS PIPELINE NETWORK

在研究燃气管网系统网络结构的多目标函数优化设计数学模型的基础上,结合VC++强大的图形开发功能,开发出了具有高效交互功能和较高计算精度的“城镇燃气管网优化设计”系统。该软件系统适用于城镇各种压力等级、各种管材、枝状、环状及混合型各种工况的燃气管网优化设计计算,并可绘制出相应的水力计算图及12类工艺计算报表。经与现场实际计算结果对比,验证了系统的可行性和可靠性,从而为从事城市高、中、低压燃气管网设计的规划设计单位,以及从事燃气管网维护、运营的企事业单位提供了设计方案及运行操作方案。

Based on the mathematic model of optimized design with multi-objective function for the network structure of gas pipeline system, using the powerful VC + + graphical function, the optimized design system of city gas pipeline network with high-efficient inter-function and high calculation accuracy is developed. The software adapts to the optimized design calculation of gas pipeline system with different situations such as various pressure levels, various pipe materials, and various network shapes (e.g. branches, rings and mixing the both). Also, the corresponding hydraulic calculation drawings and 12 types of process calculation lists are made. Comparing with the field real calculations, it is proved the system is feasible and reliable. The system provides the design programs and the operation programs for the units to design the gas network with high, medium and low pressure, and the units to maintain and operate the gas network.
