摘要
随着管网系统的复杂化和大型调峰、增压设备的增多,利用TGNET软件开展川西天然气管网系统运行调度工作的研究,通过建立川西气区管网模型开展仿真模拟计算,分别利用稳态模拟技术优选增压机组运行调度方案以及利用动态模拟技术制定应急调度方案,结果表明:若运行工况随时间参数发生变化且方案的实施也涉及时间参数,选择动态模拟更能准确地为方案决策提供技术依据;反之则选择稳态模拟运行更为简便。
So far, gas pipeline systems with more and more large-sized peak-shaving and gas-boosting facilities become more complex. In this study, TGBET software was applied to operational scheduling for gas pipelines in western Sichuan Basin. At first, a model of gas pipelines was established for this area to implement an analogue simulation; and then, one technology of steady-state simulation was used to optimize an operational scheduling plan of booster set; at the same time, another technology of dynamic-state simulation was used to formulate an emergency scheduling. Results show, if working condition varies with time, the dynamic simulation can provide technological evidence for accurately making decision of emergency scheduling whereas the steady- state simulation makes this scheduling more simple and convenient.
