摘　　要：天然气长输管道受下游用户用气不稳定的影响,一定时间内必然处于进销不平稳状态。如何借助管道现有调峰手段,确定科学、合理、高效的调峰方案是管道运营企业追求的目标。以榆林-济南输气管道(榆济输气管道)为例,评估了该管道在不同输气量下的末端调峰能力,分析了配套储气库的注采气能力及工作要求,测算了管网下游用气不均衡系数,最终结合管网实际情况,提出了优选调峰方案的措施及步骤。将榆济输气管道调峰优化问题程序化、指标化,提高了制定方案的及时性、科学性及经济性。以该管道2012-2013年冬季的调峰问题为例,验证了优化方法的可行性,得出了日调峰以管存为主,季节性调峰应采用管存及储气库联合调峰,满负荷运行状态下管存尽量不调峰等共识,将有效指导管道的运行管理工作。Due to the gas usage instability, a long-distance gas pipeline is bound to supply in unstable status in a period of time. For the pipeline operating companies, it is essential to determine scientifi c, reasonable and effi cient peaking shaving schemes with the current peaking means. Taking the Yulin-Jinan Gas Pipeline as an example, this paper evaluated its peak shaving capacity at the end of the pipeline in different delivery capacities, analyzed the gas injection and recovery capacities and work requirements of the auxiliary gas storage, and calculated the gas usage imbalance coeffi cient of downstream users. Finally, this paper put forward the measures and steps to optimize an optimal peak shaving scheme, according to the actual situation of the pipeline network. The peak shaving optimization for the Yulin-Jinan Gas Pipeline was programmed and indexed, so that the scheme could be prepared in a timely, scientifi c and economic manner. This technique was verifi ed by the peak shaving performance of the pipeline in winter of 2012-2013. It is indicated that daily peak shaving should rely on the pipeline end, seasonal peak shaving should combine the pipeline end with the gas storage, and the pipeline end peak shaving couldn＇t be used under full load operation. These results will effectively guide the operation and management of the pipeline.
