Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent carbon emission monitoring, in particular to a construction period carbon emission accounting method and system based on a substation construction process. BACKGROUND

[0002] Substation construction period carbon emission is an important part of the whole life cycle carbon emission of the substation. Strict control of the substation construction period carbon emission can effectively reduce the carbon emission caused by the substation, and accurately account for the corresponding carbon reduction means. At present, due to the poor real-time data caused by the high dispersion of emission sources and different data caliber, it is difficult to effectively monitor and control the construction period carbon emission of the substation, so that the final construction period carbon emission often far exceeds the expectation.

[0003] In the prior art, a carbon emission monitoring and early warning method during substation construction is disclosed in Chinese Patent No. CN202410978261.4, which relates to the technical field of carbon emission monitoring. During the construction of the substation, the mechanical equipment is worn out or aged with the increase of work load, which causes the energy consumption of the mechanical equipment per unit of work to gradually increase, thereby causing the carbon emission per unit of work to increase. By obtaining the energy consumption evaluation value of the mechanical equipment, the energy consumption trend function is fitted, thereby quantifying the functional degradation of the mechanical equipment. According to the energy consumption trend function, the subsequent fuel consumption is predicted, thereby obtaining the possible overall carbon emission under the current conditions, so that the future carbon emission exceeding the standard can be warned. However, it only considers the increase of carbon emission caused by the wear of mechanical equipment, and does not consider the change of carbon emission caused by other factors during actual construction, so the calculation result is difficult to be accurate.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] Please refer to Figure 1 The flowchart of the construction period carbon emission accounting method based on the construction process of a substation provided by the embodiment of the present application, further, the construction period carbon emission accounting method based on the construction process of a substation can specifically include the contents described in the following steps S1-S5.

[0020] S1: Obtain the design data and expected construction process of the target substation, and calculate the first carbon emission data expected by the target substation during the construction period according to the design data; S2: Disassemble the first carbon emission data into second carbon emission data corresponding to each construction process, and monitor the incoming building materials and incoming equipment during the construction process to form monitoring data; S3: Obtain the carbon emission data corresponding to each completed construction process as actual process carbon emission data according to the monitoring data, and calculate the actual process carbon emission data of the completed construction process as actual completion carbon emission data; S4: Calculate the sum of the second carbon emission data of the completed construction process as reference carbon emission data; S5: When the actual process carbon emission data is greater than the reference carbon emission data, adjust the construction content of the subsequent construction process not yet implemented according to the difference between the actual process carbon emission data and the reference carbon emission data.

[0021] When the embodiment of the present application is implemented, the design data and expected construction process of the target substation need to be obtained first, wherein the design data can be obtained by the design department, and the expected construction process can be obtained by the construction organization file of the construction unit. The design data is used to calculate the carbon emission data expected during the construction period, and the expected construction process is used to evaluate the carbon emission of each construction process. In order to calculate the expected carbon emission data of each construction process, the first carbon emission data needs to be disassembled into multiple second carbon emission data, each carbon emission data corresponding to a construction process. The disassembly process can be disassembled according to the construction organization file, or disassembled by a preset proportion parameter.

[0022] In the embodiment of the present application, during the construction process, the incoming building materials and incoming equipment need to be monitored, wherein the monitoring of the incoming building materials needs to include the overall monitoring of the types, quantities and transportation mileage of the incoming building materials to evaluate the building material situation required for a construction process; and the monitoring of the incoming equipment needs to monitor the types, quantities and energy consumption of the incoming equipment, including fossil energy consumption and electric energy consumption, which need to be evaluated separately.

[0023] In the embodiment of the present application, the carbon emission data of each completed construction process can be calculated based on the above-mentioned construction material and construction equipment related data; it should be understood that the construction material in the embodiment of the present application includes construction materials and equipment to be installed, and the construction equipment includes engineering machinery and transportation equipment used in construction. The carbon emission data of all completed construction processes can be obtained by summing up the carbon emission data of the completed construction processes, and the amount of carbon over-emission can be compared by comparing the sum of the data and the corresponding second carbon emission data. In order to strictly control the amount of carbon over-emission, the embodiment of the present application needs to adjust the subsequent construction processes to reduce the carbon emission of the subsequent construction processes, so as to ensure that the carbon emission of the entire substation construction period is in a controllable state. The present application can effectively monitor the carbon emission of each construction process during construction, and when the limit is exceeded, the content of the subsequent construction process is adjusted so that the carbon emission of the entire construction period is within a controllable range, effectively reducing the over-emission amount of the substation construction period.

[0024] In a possible implementation, the calculation of the first carbon emission data comprises: The construction material carbon emission data, the transportation carbon emission data and the energy carbon emission data in the construction process are calculated according to the design data, and are summed up to form the first carbon emission data; the construction material carbon emission data is the carbon emission data in the construction material production process; the transportation carbon emission data is the carbon emission data in the construction material transportation process; and the energy carbon emission data is the carbon emission data of energy use in the construction process.

[0025] When the embodiment of the present application is implemented, when calculating the total carbon emission in the construction process, all carbon emissions are divided into three parts: construction material carbon emission data, transportation carbon emission data and energy carbon emission data; the construction material carbon emission data refers to the carbon emission data generated in the construction material production process; the transportation carbon emission data refers to the carbon emission data generated by the transportation equipment in the process of transporting the construction material from the production site to the construction site; and the energy carbon emission data is the sum of the carbon emission of chemical energy and electric energy used by various equipment in the construction process. It should be understood that based on the content of the above-mentioned three data, the corresponding emission reduction means can be analyzed for emission reduction adjustment of subsequent construction processes.

[0026] In a possible implementation, the acquisition of the second carbon emission data comprises: An already completed construction substation similar to the parameters of the target substation is acquired as a typical substation, and the carbon emission proportion of each construction process during the construction of the typical substation is acquired; The product of the carbon emission proportion and the first carbon emission data is calculated as the second carbon emission data corresponding to the construction process.

[0027] In the implementation of the embodiments of the present application, in order to simplify the accounting of the possible carbon emission data corresponding to each construction process, a proportional approximation method is used for calculation, wherein a typical substation with similar parameters needs to be selected first, and the selection process needs to ensure that the typical substations have the same transformer size, the same voltage level, the same building mode, and similar building area. The same building mode mentioned here means using the same type of foundation and the same type of superstructure type. For example, if the target substation is 110kV and is equipped with 3x50000kVA transformers, and uses the building mode of raft foundation plus steel structure superstructure, then the typical substation also needs to be 110kV, equipped with 3x50000kVA transformers, and use the building mode of raft foundation plus steel structure superstructure, and the building area needs to be as close as possible to that of the target substation.

[0028] In the embodiments of the present application, by analyzing the corresponding carbon emission status of the construction period of the typical substation, the carbon emission proportion corresponding to each construction process can be calculated, which can be directly used as the carbon emission proportion of the target substation, and then the carbon emission quantity of different construction processes can be calculated.

[0029] In a possible implementation, the calculation of the actual process carbon emission data includes: According to the monitoring data, all incoming construction materials and incoming equipment corresponding to the construction process are obtained; According to the incoming construction materials and the transportation path, construction material production and transportation carbon emission data are calculated, and actual energy carbon emission data are obtained according to the energy use of the incoming equipment; The sum of all construction material production and transportation carbon emission data and the actual energy carbon emission data of the same construction process forms the actual process carbon emission data corresponding to the construction process.

[0030] In the process of calculating the actual process carbon emission data, the actual content mainly includes carbon emission data generated by the production of construction materials, carbon emission data generated in the transportation process, and carbon emission data of the energy of incoming equipment. The carbon emission data generated by production can be obtained by multiplying the number of incoming construction materials by the carbon emission coefficient in the corresponding specification. The carbon emission data in the transportation process can be obtained by obtaining the transportation mileage of the incoming construction materials and the corresponding carbon emission coefficient. The energy carbon emission data of the equipment is obtained according to the actual chemical energy use and the electric energy use. The actual carbon emission quantity of a construction process can be calculated by summing the carbon emission data of the same construction process.

[0031] In a possible implementation, adjusting the construction content of the subsequent construction process not yet implemented includes: adopting at least one of adjusting building material selection, building material localization and construction machinery electrification; The adjusting building material selection is selecting low-carbon building materials or adjusting building material configuration; the building material localization is selecting a production address with a transport distance less than a current planned transport distance; and the construction machinery electrification is increasing the proportion of electric construction machinery.

[0032] When the construction content of a construction process that has not started is reduced, three methods are mainly used, namely, adjusting building material selection, building material localization and construction machinery electrification. Since the cost of each adjustment method is different, the construction machinery electrification is generally selected first. If the construction machinery electrification alone cannot compensate for the current carbon over-release, the building material localization is selected. If the construction machinery electrification and the building material localization are selected simultaneously and still cannot compensate for the current carbon over-release, the adjusting building material selection is added to reduce carbon emissions. When the adjusting building material selection is performed, part of the structure needs to be redesigned and strength calculation needs to be performed again.

[0033] In a second aspect, the application further provides a construction period carbon emission accounting system based on a substation construction process, comprising: An acquisition unit is configured to acquire design data and expected construction processes of a target substation, and calculate first carbon emission data expected by the target substation during the construction period according to the design data; A disassembling unit is configured to disassemble the first carbon emission data into second carbon emission data corresponding to each construction process, and monitor incoming building materials and equipment during construction to form monitoring data; A calculation unit is configured to acquire carbon emission data corresponding to each completed construction process as actual process carbon emission data according to the monitoring data, calculate the actual process carbon emission data of the completed construction process as actual completion carbon emission data, and calculate a sum of the second carbon emission data of the completed construction process as reference carbon emission data; An adjusting unit is configured to adjust the construction content of a subsequent construction process that has not started when the actual process carbon emission data is greater than the reference carbon emission data according to a difference between the actual process carbon emission data and the reference carbon emission data.

[0034] In a possible implementation, the acquisition unit is further configured to: Calculate building material carbon emission data, transport carbon emission data and energy carbon emission data during the construction process according to the design data, and sum them to form the first carbon emission data; the building material carbon emission data is carbon emission data in a building material production process; the transport carbon emission data is carbon emission data in a building material transport process; and the energy carbon emission data is carbon emission data of energy use during the construction process.

[0035] In a possible implementation, the disassembling unit is further configured to: obtain a completed construction substation similar to the parameter of the target substation as a typical substation, and obtain a carbon emission proportion of each construction procedure of the typical substation during construction; calculate a product of the carbon emission proportion and the first carbon emission data as the second carbon emission data of the corresponding construction procedure.

[0036] In a possible implementation, the calculating unit is further configured to: obtain all incoming construction materials and incoming equipment of the corresponding construction procedure according to the monitoring data; calculate construction material production and transportation carbon emission data according to the incoming construction materials and the transportation path, and obtain actual energy carbon emission data according to the energy use of the incoming equipment; calculate a sum of all the construction material production and transportation carbon emission data and the actual energy carbon emission data of the same construction procedure to form the actual procedure carbon emission data of the corresponding construction procedure.

[0037] In a possible implementation, the adjusting unit is further configured to: adopt at least one of adjusting construction material selection, construction material localization, and construction machinery electrification; the adjusting construction material selection is to select low-carbon construction materials or adjust the type of construction materials; the construction material localization is to select a production address with a transportation distance less than the current planned transportation distance; and the construction machinery electrification is to improve the electrification proportion of construction machinery.

[0038] For example, the embodiment of the present application provides a specific example. Among them, the target substation is a 110kV substation in southwest, with a capacity of 2x50000kVA, using raft foundation, steel structure on the ground, steel and concrete structure underground, building area of 2231m2, total concrete of 5616.63t, total steel of 638.64t, and the construction stage carbon emission data calculated by design data is 3494.59t; In order to simplify the specific process in this embodiment, the construction process is divided into four, namely foundation and enclosure construction, main structure construction, electrical equipment installation and supporting system construction. By querying the most similar typical substation, a typical substation with a capacity of 2x50000kVA, using raft foundation, steel structure on the ground, steel and concrete structure underground, building area of 2193m2, total concrete of 5374.15t, total steel of 556.49t, and construction stage carbon emission of 3236.62t is found. By calculating the actual carbon emission of the above four construction processes of the typical substation, the proportion of foundation and enclosure construction is 38.63%, the proportion of main structure construction is 22.85%, the proportion of electrical equipment installation is 31.46%, and the proportion of supporting system construction is 7.06%. Based on the proportion, the second carbon emission data of foundation and enclosure construction is calculated as 1349.96t, the second carbon emission data of main structure construction is calculated as 798.51t, the second carbon emission data of electrical equipment installation is calculated as 1099.40t, and the second carbon emission data of supporting system construction is calculated as 246.72t.

[0039] In the construction process, during the monitoring of the construction process of the foundation and enclosure structure construction, it is found that the carbon emission data obtained after the completion of the foundation and enclosure structure construction is 1467.65t, which is 117.69t over the limit, and the reason is that the concrete is used in excess; at this time, according to the priority, the construction machinery is first selected to be electrified, and the 4 60t crawler cranes used in the subsequent main structure construction are replaced by a 400t self-elevating tower crane, wherein the diesel consumption of the 60t crawler crane is 47.17kg per shift, and the power consumption of the 400t self-elevating tower crane is 164.31kwh per shift; the number of shifts is 120 days, the total carbon emission of the crawler crane is 71.25t, the total carbon emission of the 400t self-elevating tower crane is 10.98t, and the total carbon emission is 60.27t. There is a gap of 57.42t. At this time, the selection of local building materials is further reduced, and it is found that the main construction steel is purchased from a steel plant 483 kilometers away, and due to road conditions, only 18t heavy diesel trucks can be used for transportation, with a carbon emission factor of 0.129kg / (t*km), and the total transportation carbon emission is 27.33t. After purchasing nearby, the distance is shortened to 44km, and 46t heavy diesel trucks can be used for transportation, with a carbon emission factor of 0.057kg / (t*km), and the total transportation carbon emission is 1.10t, and the total carbon emission is 26.23t. There is a gap of 31.19t. At this time, the building material needs to be adjusted, and part of the Q420 hot-rolled section is replaced by Q420 high-frequency welded H-shaped steel, and after the strength calculation is passed, the cross section is optimized to reduce the weight by 12%, and the total carbon emission is reduced by 52.3t, and the carbon emission reduction goal is achieved.
