Research on the optimization technology of pipeline operation based on en-ergy measurement
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/m3 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 14.824 3 million yuan/d to 15.474 7 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.
