TGNET和SPS在甬台温输气管道设计中的比较

结合甬台温输气管道,分别从建模、有效性检验、工况运行和结果读取4个方面定性分析TGNET和SPS软件在管道工程设计应用中的异同,对多气源管道的稳态动态模拟、最大储气能力和最大输气能力进行计算,并对结果进行定量比较.在相同设置、相同参数的情况下,两款软件的计算结果相近,但又各具特点:TGNET通过实物建模,操作简单、易于掌握,适用于稳态模拟和简单动态模拟；SPS可采用实物和文本编程两种方式建模,其Intran文件逻辑编辑功能强大,并可分段导入中线成果数据,生成断面线,可以随时查看运行结果、调整输入参数,交互性能好.基于此,提出建议:当需要中线成果数据导入及进行动态模拟时,特别是需要模拟多种逻辑控制的复杂管网,SPS明显优于TGNET,在其他情况下,宜采用操作简单的TGNET软件进行工艺计算.

Comparison of TGNET and SPS in the design of YongTaiWen Gas Pipeline

To more accurately select the TGNET or SPS software for the process calculation of multi-gas source gas pipeline projects,based on its application in YongTaiWen Gas Pipeline,qualitative analysis is carried out for similarities and differences of the two software in pipeline engineering design applications from four aspects of modeling,validation check,operation conditions and result reading,the steady-state dynamic simulation,maximum storage capacity and maximum gas transmission capacity of multi-gas source pipeline are calculated and quantitative comparison is conducted on the calculation results.In the case of the same equipment installations and parameters,calculation results of TGNET and SPS are very close,but have different characteristics,that is,TGNET subject to physical modeling and simple operation is easy to grasp and applicable to the steady-state simulation and simple dynamic simulation;SPS subject to physical and textual programming modeling and with its strong Intran file logic editing function can be imported with midline data results in segments,generate cross hatching line,view operating results at any time and adjust input parameters with good interactive performance.Based on the above analysis,it is recommended that when the import of midline results data and dynamic simulation are required,and especially when it is required to simulate complex pipe network subject to multiple logic controls,SPS software will be significantly better than TGNET software,and TGNET with simple operations should be used for process calculation in other cases.
