Embodiment 1
[0052] Embodiment 1. The multi-transmission and difference collaborative calculation model of the urban gas pipeline network. The urban gas pipeline network is taken as a whole and divided into some individual gas transmission lines L1...Lk, and the gas supply port and the gas connection port are divided into the entire gas pipeline network. , gas transmission branch port, gas sales port, gas supply flowmeter is configured at the gas supply port, gas connection flowmeter is configured at the gas connection port, flow meters are configured at each branch port, and sales flow meters are configured at the gas sales port. The application methods include gas pipes Network receiving and transmission method, gas pipeline network sales transmission method, and gas pipeline network i-th gas transmission line transmission method.
Embodiment 2
[0053] Embodiment 2. Gas pipeline network receiving and transmission method:
[0054] (1) The gas purchase metering of the gas pipeline network for a period of time is the sum of all gas purchase meters in the entire gas pipeline network:
[0055] Q t总购气 =∑Q t购气表i i=1 to m
[0056] Among them: Q t总购气 : The total gas purchase volume of the gas pipeline network over a period of time, Nm 3 .
[0057] Q t购气表i : Gas purchase volume of the i-th purchase meter Fgi in a period of time, Nm 3
[0058] (2) The received gas metering of the gas pipeline network for a period of time is the sum of the received gas meters in the entire gas pipeline network:
[0059] Q t总接收 =∑Q t接收i i=1 to n
[0060] Among them: Q t总接收 : The total gas intake volume of the gas pipeline network for a period of time, Nm 3 .
[0061] Q t接收i : Gas volume of the i-th receiving gas meter Fji for a period of time, Nm 3
[0062] (3) The gas storage capacity of the gas pipeline network is poor for a perio...
Embodiment 3
[0071] Embodiment 3. Gas pipeline network sales transmission method:
[0072] (5) The sales gas metering of the gas pipeline network for a period of time is the sum of the sales gas measurements in the entire gas pipeline network:
[0073] Q 总销气 =∑Q 销气表i i=1 to k
[0074] Among them: Q 总销气 : The total gas sales volume of the gas pipeline network over a period of time, Nm 3 .
[0075] Q 销气表i : gas sales volume of the i-th gas sales meter Fxi in a period of time, Nm 3
[0076] (6) The method of sales and transmission difference of gas pipeline network for a period of time:
[0077] ΔQ t销气输差 = Q t总接收 -Q 总销气 -Q t总管存气量差
[0078]
[0079] Among them: △Q t销气输差 : The total gas sales and transmission difference of the gas pipeline network over a period of time, Nm 3 .
[0080] ΔQ d销气输差 : The percentage of the total gas sales and transmission difference of the gas pipeline network for a period of time.
