Abstract Based on the hydraulic calculation method for dynamic simulation of gas pipeline network, the mixed transmission node traffic allocation solution method and heat dynamic assignment method are coupled, and the implicit difference method is used for numerical solution. Based on the above method, the calorific assignment software of the multi-source natural gas pipeline network is compiled, and the calorific assignment calculation is carried out. It is verified that the error between the calculated natural gas calorific value and the measured results is within 0.36%, which meets the maximum tolerance requirements of GB/T 18603 ‘Technical Requirements for Natural Gas Metering Systems’. The method realizes the functions of temperament tracking and dynamic calorific value assignment of multi-gas source natural gas pipeline network.
