由于气源供应不足、设备故障、自然灾害、用户用气需求增加等原因，天然气管网运营部门需要对各个用户供应量进行重新分配和调整，而天然气在管网系统的运行过程中，其运行参数受流动规律的限制，用户对天然气供应压力和流量也有相应的要求。在综合考虑管网运行特性和用户用气需求的基础上，以用户重要度作为配置天然气供应量的依据，提出基于重要用户优先服务策略的天然气管网资源优化分配模型，优化资源分配，减少天然气的低效利用率，降低因天然气供应紧急、短缺带来的不利影响。以一个由35个节点、33条管段和3个压缩机站构成，涉及各个用户类型的实际管网为例，应用建立的模型和方法，通过计算得出管网系统的最优运行方案，为生产运行调度提供了重要依据。

Due to equipment failures,natural disasters,supply shortage and increased demand for natural gas,the natural gas pipeline network operations department needs to distribute and adjust the supply for individual user.However,operation parameters were restricted by flowing law when natural gas flowed in the process of the pipeline system,the gas supply pressure and flow rate must also meet the requirements established by users.Based on the gas pipeline operation features,user needs and service priority,natural gas pipeline network resources optimization allocation model was put forward based on the priority service of important user to optimize the resources allocation and reduce the inefficiency utilization of natural gas and negative influence of shortage of natural gas supply.It took an actual example involving 33 pipes,35 nodes,3 compressor stations and the various types of users and applied the model and method,calculated the optimal operation schemes of pipeline system,which provided an important basis for operation scheduling.
