Description

TECHNICAL FIELD

[0002] Taking a natural gas pipeline trunk as an example, the gas storage capacity of the pipeline can be used as a control basis for upstream gas source intake, downstream distribution station, user end distribution and gas storage capacity of the gas storage. By determining the gas storage capacity of each pipeline trunk in the pipeline, it is beneficial to the stability of the gas compression station and the economic operation of the pipeline.

[0003] At present, there are the following problems in the calculation and analysis of pipeline gas storage: first, considering the mutual influence of each pipeline, realizing the balance of the whole network; second, the pipeline scale is large, and the calculation workload of the whole network gas storage is large; third, the number of distribution stations, gas compression stations and user ends is large, and the pipeline topology structure is very complex. At present, for a single pipeline trunk, the steady-state simulation method is generally used to determine the gas storage capacity of each pipe section in each pipeline trunk. However, this method cannot avoid the influence of temperature drop on the gas storage capacity of each pipe section, thereby leading to inaccurate determination of the pipe section gas storage capacity, which greatly affects the subsequent scheduling of the energy in the pipe section and cannot well optimize the total gas storage capacity of each pipe section in the pipeline trunk.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiments of the present application, and is not used to limit the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0038] Figure 1 The flowchart of the control method of energy in a pipeline trunk according to the embodiments of the present application is schematically shown. As Figure 1As shown in an embodiment of the present application, a method for controlling energy in a pipeline trunk is provided, each pipeline trunk comprising a plurality of pipe sections, the method comprising the following steps:

[0039] In step 101, for any one pipe section, the pipe section is divided into a plurality of sub-pipe sections according to a preset distance.

[0040] In step 102, the total amount of pipe storage of the energy to be transported in each pipe section is determined according to the pressure and temperature corresponding to the start and end of each sub-pipe section.

[0041] In step 103, the gas source supply amount of the energy to be transported at the gas source point where each pipe section is located is obtained.

[0042] In step 104, in the case where the gas source supply amount is less than the gas source demand amount, the first scheduling amount of the energy to be transported in each pipe section is determined according to the gas source supply amount and the gas source demand amount.

[0043] In step 105, in the case where the first ratio of the first scheduling amount to the total amount of pipe storage is less than a first preset value, the second scheduling amount of the energy to be transported is determined according to the gas source supply amount and the first scheduling amount.

[0044] In step 106, for any one pipe section, the pipe section is controlled to transport the second scheduling amount of the energy to be transported to the target receiving point.

[0045] The pipeline trunk can refer to a device for transporting energy. The energy to be transported can include gas. Specifically, the gas can refer to natural gas, which can include purchased natural gas and domestically produced natural gas. Each pipeline trunk can include a plurality of pipe sections. When controlling the energy in the pipeline trunk, the processor can divide any one pipe section into a plurality of sub-pipe sections according to a preset distance. The preset distance can be customized according to actual conditions. The length of each sub-pipe section can be equal to the preset distance, or less than the preset distance. For example, for any one 10.5 km pipe section A, the processor can divide it into 11 sub-pipe sections (a1, a2, … a10, a11) according to a preset distance of 1 km. The length of sub-pipe sections a1-a10 is 1 km, and the length of sub-pipe section a11 is 0.5 km. Since the length of the sub-pipe section is small enough, it can be approximated as a node of each pipeline trunk, and the influence of temperature drop on the pipe storage of the sub-pipe section is small, which can improve the accuracy of the total amount of pipe storage of each pipe section.

[0046] In the case that each pipe section is divided into a plurality of sub-pipe sections, the processor can determine the pipe inventory of the energy to be transported in each sub-pipe section according to the pressure and temperature corresponding to the start end and the end of each sub-pipe section, and can further determine the total pipe inventory of the energy to be transported in each pipe section as the sum of the pipe inventory of the energy to be transported in each sub-pipe section. The energy to be transported can refer to natural gas. In the case that the total pipe inventory of the energy to be transported in each pipe section is determined, the processor can obtain the gas source supply amount of the energy to be transported at the gas source point where each pipe section is located. The gas source point can refer to the source of the energy to be transported, and specifically, the gas source point can refer to the gas source point of the pipeline trunk where each pipe section is located. The gas source supply amount of the energy to be transported at the gas source point where each pipe section is located can be the same.

[0047] The processor can further determine the size relationship between the gas source supply amount and the gas source demand amount of the energy to be transported at the gas source point where each pipe section is located. The gas source demand amount can be customized according to user demand. If the gas source supply amount is less than the gas source demand amount, at this time the storage amount of the energy to be transported at the gas source point of the pipe section is insufficient to meet the energy demand amount of the user. In this case, the processor can call up the energy to be transported in the pipe section corresponding to the gas source point. Further, the processor can determine the first scheduling amount of the energy to be transported in each pipe section according to the gas source supply amount and the gas source demand amount. The first scheduling amount can be the difference between the gas source supply amount and the gas source demand amount. For example, if the gas source supply amount at the gas source point where the i-th pipe section is located is less than the gas source demand amount of the i-th pipe section , the energy to be transported in the i-th pipe section can be called up. If the gas source supply amount at the gas source point where the i-th pipe section is located is greater than or equal to the gas source demand amount of the i-th pipe section , at this time the supply amount of the gas source point of the pipe section meets the energy demand amount of the user, and the energy to be transported in the i-th pipe section can not be called up.

[0048] The processor can determine the first ratio between the first scheduling amount and the total pipe inventory of the energy to be transported in each pipe section, and can compare the first ratio with a first preset value. If the first ratio is less than the first preset value, at this time the amount of energy that can be scheduled in the pipe section can meet the user demand. In an embodiment, the first preset value can be 0.03. For example, if the first scheduling amount of the i-th pipe section is less than the total pipe inventory of the energy to be transported in the i-th pipe section ​​the first ratio is less than 0.03, the energy amount that can be dispatched in the ith pipe section can meet the user demand. In the case that the first ratio is less than the first preset number, the processor can determine a second dispatch amount of the to-be-delivered energy according to the gas source supply amount and the first dispatch amount. Specifically, the second dispatch amount can be the sum of the gas source supply amount and the first dispatch amount. For example, the second dispatch amount of each pipe section can be determined by determining, wherein, may refer to the second dispatch amount of the ith pipe section, may refer to the gas source supply amount of the gas source point where the ith pipe section is located, may refer to the first dispatch amount of the ith pipe section. For any one pipe section, the processor can control the to-be-delivered energy of the second dispatch amount in the gas source point where the pipe section is located to be delivered to a target receiving point. The target receiving point can refer to an energy storage location specified by the user.

[0049] By the above technical solution, each pipe section is divided into multiple sub-pipe sections, so that the influence of temperature drop on the pipe inventory of the sub-pipe section is small, the storage amount of the to-be-delivered energy in each pipe section can be more accurately determined, and the accuracy of subsequent allocation of the to-be-delivered energy in the pipe section is further improved. The dispatch amount of the to-be-delivered energy is determined by the gas source supply amount and the gas source demand amount, which can optimize the total amount of the pipe inventory of each pipe section in the pipeline trunk.

[0050] In one embodiment, the control method further comprises: for any one sub-pipe section, in the case that the sub-pipe section is the first sub-pipe section of the pipe section, determining that the first pressure and the first temperature at the start end of the sub-pipe section are a preset pressure and a preset temperature, respectively; for any one sub-pipe section, in the case that the sub-pipe section is not the first sub-pipe section of the pipe section, determining that the first pressure and the first temperature at the start end of the sub-pipe section are the pressure and the temperature at the end of the previous sub-pipe section, respectively; determining the second pressure and the second temperature at the end of each sub-pipe section according to the first pressure and the first temperature at the start end of each sub-pipe section, respectively.

[0051] For any one sub-pipe section, in the case that the sub-pipe section is the first sub-pipe section of the pipe section, the processor can determine that the first pressure and the first temperature at the start end of the sub-pipe section are preset pressure and preset temperature respectively. Wherein, the pipe section can refer to the first pipe section of the pipeline trunk. That is, if the sub-pipe section is the first sub-pipe section of the first pipe section of the pipeline trunk, the preset pressure can refer to the starting pressure of the gas source point of the pipeline trunk, and the preset temperature can refer to the starting temperature of the gas source point of the pipeline trunk. For any one sub-pipe section, in the case that the sub-pipe section is not the first sub-pipe section of the pipe section, the processor can determine that the first pressure and the first temperature at the start end of the sub-pipe section are the pressure and the temperature at the end of the last sub-pipe section respectively. Wherein, the pipe section can refer to the first pipe section of the pipeline trunk. That is, if the sub-pipe section is not the first sub-pipe section of the first pipe section of the pipeline trunk, the first pressure and the first temperature at the start end of the sub-pipe section are the pressure and the temperature at the end of the last sub-pipe section respectively. The processor can determine the second pressure and the second temperature at the end of each sub-pipe section according to the first pressure and the first temperature respectively.

[0052] For example, taking the pipeline trunk B as an example, the pipeline trunk B includes the pipe section B1, the pipe section B1 is the first pipe section of the pipeline trunk B, the pipe section B1 includes sub-pipe sections , ,… , , and the sub-pipe section is the first sub-pipe section of the pipe section B1, and the sub-pipe section is the last sub-pipe section of the pipe section B1. For the sub-pipe section , which is the first sub-pipe section of the pipe section B1, the first pressure and the first temperature at the start end of the sub-pipe section are determined as preset pressure and preset temperature. The preset pressure can be the starting pressure of the gas source point of the pipeline trunk B, and the preset temperature can refer to the starting temperature of the gas source point of the pipeline trunk B. For the sub-pipe section , which is the second sub-pipe section of the pipe section B1, the pressure and the temperature at the start end of the sub-pipe section are determined as the pressure and the temperature at the end of the sub-pipe section of the pipe section B1 respectively.

[0053] In one embodiment, the control method further comprises: for any one pipe section, determining that the second pressure and the second temperature at the end of the last sub-pipe section of the pipe section are the first pressure and the first temperature at the start end of the first sub-pipe section of the next pipe section respectively; determining the second pressure and the second temperature at the end of the first sub-pipe section of the next pipe section according to the first pressure and the first temperature at the start end of the first sub-pipe section of the next pipe section.

[0054] For any one pipe section, the processor can determine the second pressure and the second temperature at the end of the last sub-pipe section of the pipe section as the first pressure and the first temperature at the start of the first sub-pipe section of the next pipe section. The processor can determine the second pressure and the second temperature at the end of the first sub-pipe section of the next pipe section according to the first pressure and the first temperature at the start of the first sub-pipe section of the next pipe section. For example, taking the pipeline trunk B including pipe sections B1 and B2 as an example, the pipe section B1 is the first pipe section of the pipeline trunk B, and B2 is the second pipe section of the pipeline trunk B. The pipe section B1 includes sub-pipe sections , ,... , , where the sub-pipe section is the first sub-pipe section of the pipe section B1, and the sub-pipe section is the last sub-pipe section of the pipe section B1. The pipe section B2 includes sub-pipe sections , ,... , , where the sub-pipe section is the first sub-pipe section of the pipe section B2, and the sub-pipe section is the last sub-pipe section of the pipe section B2. For the pipe section B1, the second pressure and the second temperature at the end of the last sub-pipe section of the pipe section B1 are the first pressure and the first temperature at the start of the first sub-pipe section of the pipe section B2, respectively.

[0055] In one embodiment, determining the second pressure and the second temperature at the end of each sub-pipe section according to the first pressure and the first temperature at the start of each sub-pipe section respectively includes: determining the current flow of the energy to be transported in each sub-pipe section; for any one sub-pipe section, determining the second pressure at the end of the sub-pipe section according to the first pressure, the first temperature, the current flow, and the friction coefficient between the energy to be transported in the sub-pipe section and the inner wall of the pipeline of the sub-pipe section; for any one sub-pipe section, determining the second temperature at the end of the sub-pipe section according to the first pressure, the first temperature, the second pressure, and the specific heat capacity at constant pressure.

[0073] (3)

[0074] wherein, is the pipe inventory of the energy to be transported in the sub-pipe section, is the pipe capacity of the sub-pipe section, is the average pressure of the sub-pipe section, is the compressibility factor of the energy to be transported in the sub-pipe section under standard conditions, is the temperature under standard conditions, the value of which is 293.15 K, and P is the pressure of the sub-pipe section under standard conditions, is the compressibility factor of the energy to be transported in the sub-pipe section, 0.904, is the average temperature of the sub-pipe section.

[0075] In an embodiment, the pipe capacity of the sub-pipe section may be determined by , wherein D is the pipe diameter of the sub-pipe section, and L is the length of the sub-pipe section.

[0076] In an embodiment, the control method further comprises: in a case where the first ratio of the first scheduling quantity to the total pipe inventory is equal to a first preset value, determining a third scheduling quantity of the energy to be transported according to the total pipe inventory; determining a second ratio between the sum of the scheduling quantities of the gas source supply quantity and the third scheduling quantity and the gas source demand quantity; and in a case where the second ratio is greater than or equal to a second preset value, determining the sum of the scheduling quantities as a second scheduling quantity of the energy to be transported.

[0077] In a case where the first ratio of the first scheduling quantity to the total pipe inventory is equal to a first preset value, the processor can determine a third scheduling quantity of the energy to be transported according to the total pipe inventory. In an embodiment, the first preset value can be 0.03. For example, if the first preset value is 0.03, and the first ratio of the first scheduling quantity to the total pipe inventory is equal to the first preset value at this time, the processor can determine the total pipe inventory multiplied by 0.03 as the third scheduling quantity of the energy to be transported. That is, the third scheduling quantity is the maximum scheduling quantity of the energy to be transported in the pipe section at this time. In this case, the processor can further determine a second ratio between the sum of the scheduling quantities of the gas source supply quantity and the third scheduling quantity and the gas source demand quantity, and can compare the second ratio with a second preset value. In an embodiment, the second preset value can have a value range of 0-1. If the second ratio is greater than or equal to the second preset value, it can be determined that the sum of the scheduling quantities determined at this time can meet the energy demand of the user. The processor can determine the sum of the scheduling quantities as a second scheduling quantity of the energy to be transported, and can further control the pipe section to transport the second scheduling quantity of the energy to be transported to the target receiving point.

[0078] In one embodiment, the control method further comprises: in the case that the first ratio of the scheduled quantity to the total quantity of the pipe storage is greater than the first preset value, sending an alarm prompt to prompt that the scheduled quantity of the pipe section exceeds the upper limit. When the pipe section worker receives this prompt, the prompt that the scheduled quantity exceeds the upper limit can be reported to the operation department.

[0079] In one embodiment, the processor can control the energy to be transported of each pipe section of the pipeline trunk by controlling the energy to be transported of each pipe section of the pipeline trunk. Wherein, may refer to the second scheduled quantity of the i-th pipe section, may refer to the gas source demand quantity of the i-th pipe section, may refer to the weight of the i-th pipe section, and maxF may refer to the maximum value of the sum of the product of the second scheduled quantity and the gas source demand quantity of the N pipe sections under the preset constraint condition and the weight of the pipe section. Wherein, the preset constraint condition is , 0.03 , . Wherein, The value range of can be 0-1.

[0080] In one embodiment, as Figure 2 shown, an example diagram of a pipeline trunk is provided. Each pipeline trunk can serve as a primary pipeline, and each primary pipeline includes n sub-transmission stations. There is a gas source point at the source of the primary pipeline, and the gas source can include imported natural gas and domestically produced natural gas. The pipeline between every two adjacent sub-transmission stations is a secondary pipeline, and each secondary pipeline can be the aforementioned pipe section. As Figure 3 shown, an example diagram of a pipe section is provided. The pipe section between the No. 1 sub-transmission station and the No. 2 sub-transmission station can be a secondary pipeline, which can be the aforementioned pipe section. As Figure 4 shown, each secondary pipeline can be divided into multiple tertiary pipelines according to a preset distance, and each tertiary pipeline can be the aforementioned sub-pipe section. For example, the secondary pipeline between the No. 1 sub-transmission station and the No. 2 sub-transmission station can be divided into multiple tertiary pipelines. Since there is a sub-transmission station between every two adjacent secondary pipelines, the sub-transmission station can unload the energy in the pipeline, and there is an unloading quantity of energy to be transported between every two secondary pipelines. Therefore, the storage quantities of the energy to be transported in every two secondary pipelines are different. For the multiple tertiary pipelines included in each secondary pipeline, there is no unloading quantity of energy to be transported between every two tertiary pipelines. By determining the pipe storage quantity of each tertiary pipeline to determine the total pipe storage quantity of each secondary pipeline, each tertiary pipeline can be regarded as a node, and the starting point temperature of each tertiary pipeline can be regarded as the average temperature of the secondary pipeline.

[0081] By dividing each pipeline segment into multiple sub-segments, the aforementioned technical solution minimizes the impact of temperature drops on the pipeline inventory within each sub-segment. This allows for more accurate determination of the amount of energy to be transported within each segment, further improving the accuracy of subsequent energy allocation within that segment. By determining the dispatched amount of energy to be transported based on the gas supply and demand, the total pipeline inventory within each segment of the pipeline can be optimized.
