靖西天然气管道负荷不均衡性及应对策略

Load imbalance of Jingxi Natural Gas Pipeline and relevant solutions

  • 摘要: 随着陕西省天然气产业的快速发展,靖西天然气管道的供需矛盾日益突出,其负荷存在明显的不均衡性,不利于高效平稳输气。为此,在梳理靖西天然气管道下游用气特性的基础上,采用相关性分析法得出了影响其年负荷的4个主要因素;引入月不均匀系数对靖西天然气管道近几年的月负荷规律进行研究,依据供需平衡法对靖西天然气管道的供需形势进行分析。结果表明:靖西天然气管道供需形势存在年不均衡性,且由于用气结构不合理导致其季节不均衡性突出。由此建议:通过大力开发市场、推进“气化陕西”民生工程等策略,解决靖西天然气管道负荷的年不均衡状况;同时,通过建设LNG调峰工厂等方式,缓解靖西天然气管道负荷的季节不均衡性。

     

    Abstract: With the rapid expansion of the natural gas industry in Shaanxi Province, the contradiction between supply and demand for Jingxi Natural Gas Pipeline has become increasingly prominent. Its high load imbalance is not conducive to the smooth and efficient gas transmission. Therefore, through identifying the downstream gas consumption features of Jingxi Natural Gas Pipeline, four main factors influencing the annual load of the pipeline are obtained by the correlation analysis method. Moreover, the monthly imbalance coefficient is imported to analyze the monthly loads of Jingxi Natural Gas Pipeline in recent years; according to the supply and demand balance method, the supply and demand situation of Jingxi Natural Gas Pipeline is analyzed. The results show that the Jingxi Natural Gas Pipeline demonstrates annual imbalance of supply and demand and especially seasonal imbalance due to unreasonable gas consumption structure. This paper hereby proposes that: (1) the annual imbalance of Jingxi Natural Gas Pipeline is addressed through vigorously developing the market and promoting the strategy of "Shaanxi gasification" and other livelihood projects; and (2) the seasonal imbalance of load imbalance of Jingxi Natural Gas Pipeline is relieved by constructing the LNG peak shaving plant.
