摘　　要：为实现天然气贸易交接从体积计量方式尽快转为能量计量方式,在梳理不同能量计量价格转换方式的前提下,确定适合我国的能量计量体系,建立以管道运行利润最大为目标函数的优化模型,在管道压力约束、气源和用户压力约束、流量平衡约束等条件下,通过优化数学算法完成求解,并在现场进行实际应用和结果验证。结果表明,以36.84 MJ/m^(3)作为基准热值的能量计量结果更为合理,与原体积计量结果差距不大;优化后,应降低高热值气源流量,增加低热值气源流量,销售收益、购气成本和运行成本均有所下降,经济效益从1482.43万元/d提升至1547.47万元/d,预计全年可增加经济效益2.3亿元。研究结果可为能量计量的推广和应用提供实际参考。In order to realize the transfer of natural gas trade from volume measurement to energy measurement as soon as possible,on the premise of sorting out different energy measurement price conversion modes,the energy measurement system that is suitable for China has been determined,and the optimization model with the maximum profit of pipeline operation as the objective function has been established.Under the conditions of pipeline pressure constraints,gas source,user pressure constraints,and flow balance constraints,the solution is completed through the optimization of mathematical algorithm,and the practical application and result verification are carried out in the field.The results show that the energy measurement with 36.84 MJ/m^(3) as the reference calorific value is more reasonable,and the difference with the original volume measurement is not much.After the optimization,the flow rate of high calorific value air source should be reduced,and the flow rate of low calorific value air source should be increased.The sales income,gas purchase cost and operating cost have all decreased,and the economic benefit has increased from 14.8243 million yuan/d to 15.4747 million yuan/d,and it is expected that the annual economic benefit can be increased by 230 million yuan.The research results can provide practical reference for the promotion and application of energy measurement.
