摘要 随着天然气管网规模不断增大以及运行条件日益复杂,对管网集中调控提出了更高的要求,仅凭调度员经验难以全面应对管网运行问题,亟需高效的优化工具辅助制订运行方案,调整日常工况。将最优化技术应用于天然气管网运行中,分别以管道水力热力计算校核、压气站负荷分配、单条输气管道运行方案、复杂输气管网运行方案为优化对象,建立了相应的最优化模型,并提出了求解方法。最优化技术是解决天然气管网生产实际问题的有效方法,但仍需突破精准优化模型建立、优化模型高效求解以及优化结果分析利用等技术瓶颈。最后,展望了最优化技术在非稳态优化、控制系统优化以及全生命周期优化方面的应用前景。 As the scale of natural gas pipeline network is increased continuously and its operation conditions get more and more complicated, its central regulation and control shall meet more requirements. In this case, the problems involved in pipeline operation can be hardly solved comprehensively if dispatchers do the judging only based on their experience. Therefore, efficient optimization tools are in urgent need to assist the formulation of operation schemes and the regulation of daily conditions. In this paper, the application of optimization technology in the operation of natural gas pipeline network was described. Then, the corresponding optimization model was established and the solution method was developed with four cases as optimization objects, i.e., the hydraulic and thermal calculation checking of pipeline, the load distribution of compressor station, the reasonable optimization of single gas pipeline operation scheme, and the complex pipeline network operation scheme. It is pointed out that the optimization technology is an effective way to solve some practical production problems of natural gas pipeline network, but it is still necessary to strengthen the researches to break through the technical and application bottlenecks, e.g. the establishment of precise optimization model, the efficient solution of optimization model and the analysis and utilization of optimization result. Finally, the application prospect of optimization technology in transient optimization, control system optimization and even whole life cycle optimization was predicted.
