输气管道压气站装机功率及备用系数的选择

Selection of Installed Capacity or Stand-by Factor of Compression Station on Gas Pipelines

输气管道压气站装机功率及备用系数的选择，直接影响到输气管道正常运行的可用性、可靠性和经济性。结合燃气轮机、天然气压缩机及天然气管道的有关特性，通过对大、小机组方案进行对比，从技术、经济两方面论述天然气输气管道压气站装机功率及备用系数的合理选择，并对隔站增压运行方式进行了分析。

Selection of installed capacity or stand-by factor of compression station has a direct impact on the availability, reliability and economics of gas pipelines. Based on relevant characteristics of gas turbines, gas compressors and gas pipelines, selection of installed capacity or stand-by factor of compression station on gas pipelines are discussed from both technical and economic points of view through comparison of large and small installed capacities. Also, a new boosting mode-boosting for every another station is discussed.
