近年来,由于城市人口大幅度增长,工业迅猛发展,导致城区燃气负荷不断增加,现有城区燃气管网供气能力面临巨大的挑战,在此情况下开展城区燃气管网故障工况适应性分析具有积极意义。建立了M市城区燃气管网水力计算模型,借助于TGNET水力计算软件完成了该市城区燃气管网的故障工况水力计算,分析了城区燃气管网在故障工况下的适应性。研究结果表明:城区燃气管网在故障工况下具有很高的适应性,在未来很长一段时间内都能较好地满足城区燃气负荷需求。此研究模型与方法能为其他同类型城市燃气管网故障工况适应性评价提供有效的借鉴。
In recent years, with the rapid growth of the urban population and the rapid industrial development, the gas load in the urban area has been continuously increasing. As a result, the gas supply capacity of the existing urban gas pipeline network faces enormous challenges. Under such circumstances, the adaptive analysis of the urban gas pipeline network fault conditions Has a positive meaning. The hydraulic calculation model of gas pipeline network in urban area of M city was established. With the aid of TGNET hydraulic calculation software, the hydraulic calculation of the fault gas pipeline network in urban area was completed and the adaptability of gas pipeline network in urban area under fault conditions was analyzed. The results show that the gas pipeline network in urban area has high adaptability under fault conditions and can meet the gas load demand in urban areas for a long time in the future. This research model and method can provide an effective reference for the adaptive evaluation of the fault conditions of gas pipelines in other cities.
