摘　　要：为了使油气集输系统能量利用更加科学有效,将分布式能源系统的供能、用能理念应用于油气集输系统设计中。按照"以热定电"的原则设计了油气集输分布式能源系统:将燃气轮机和余热锅炉应用于油气集输系统,燃气轮机发电为集输系统提供电能,利用余热锅炉回收发电后的尾气余热为集输系统提供热能,系统盈余的电力上网。实例计算结果表明:与常规集输站相比,分布式能源系统集输站能量利用率提高7.01%,效率提高16.5%;同时,油气集输分布式能源系统年节省费用开支498.29×104元。可见,将分布式能源系统应用于油气集输,既可以提高系统的节能性,又具有很好的经济性,值得推广应用。In order to enable energy utilization of oil ＆ gas gathering system to be more scientific and effective, the concept of power supply and consumption of distributed energy system is applied to the design of oil ＆ gas gathering system. The principle of＂power decided by heat＂ is used to design distributed energy system ofoil ＆ gas gathering： gas turbine and heat recover steam generator （HRSG） are applied to oil ＆ gas gathering system, the gas turbine provides power for the gathering system, the waste-heat of tail gas after power generation is recycled by HRSG to provide heat energy for the gathering system, and the surplus power of the system is connected with the power grid. Through case calculation, results indicate that compared with conventional gathering station, the energy utilization rate of gathering station of distributed energy system is increased by 7.01%, and the efficiency of exergy is increased by 16.5%. At the same time, distributed energy system of gathering station can save RMB 498.29x 104 each year. Therefore, it can be seen that, the application of distributed energy system to oil ＆ gas gathering can improve energy conservation and is economical, which is worth popularizing and applying. （2 Figures, 5 Tables, 11 References）
