Since the building materials are used immediately, the two links are carried out in parallel in a long term and are carried out in sequence in a short term. The procurement link includes a raw material ordering link and a raw material transportation link. The construction and construction link includes a civil engineering link and an electrical equipment installation link. The civil engineering link includes building construction and structure construction. The electrical equipment installation link covers installation of primary equipment and secondary equipment and subsequent test and debugging work. In addition, these links can be further refined. Therefore, the multiple links of the substation engineering construction exist in parallel relationship and nested relationship.
[0003] The procurement link is the primary link of the substation engineering construction, including a raw material ordering link and a transportation link, and plays a decisive role in subsequent engineering links. Specifically, the procurement link includes demand identification and analysis, product screening, supplier evaluation, bidding and contract management, quality and environment monitoring, and continuous improvement and feedback. According to the power grid equipment and material procurement standard issued by the State Grid Corporation, the specification technical requirements are implemented in the raw material ordering link, which provides a solid foundation for improving the quality of equipment and materials and ensuring the safe and stable operation of the project.

[0043] In some embodiments, the computing device 100 performing the substation engineering carbon emission accounting method 200 in embodiments of the present application can be a terminal or a server.
[0044] The substation engineering carbon emission accounting method 200 in embodiments of the present application is described in detail as follows.
[0045] Figure 2 A flowchart of a substation engineering carbon emission accounting method 200 according to embodiments of the present application is shown. As shown in FIG. 1, the substation engineering carbon emission accounting method 200 includes the following steps. Figure 2As shown, the substation engineering carbon emission accounting method 200 includes the following steps 210-240.
[0046] Step 210, the computing device 100 can first determine the accounting boundary of the substation engineering carbon emission, the accounting boundary including a plurality of stages, the plurality of stages including a procurement stage, a construction stage, and an operation stage.
[0047] Step 220, the computing device 100 can obtain carbon emission activity data of each stage of the substation engineering based on the accounting boundary, the carbon emission activity data being used to represent the production or consumption activity that causes carbon emission. The carbon emission activity data includes material consumption and energy consumption.
[0048] In some embodiments, in step 220, the decomposition statistical method, the parameter fitting method, or the process tracing method can be used to obtain the carbon emission activity data of each stage of the substation engineering. Specifically, for the decomposition statistical method, engineering data of the substation engineering can be obtained, and the engineering data can be decomposed into component, part, and process data with credible emission factors, and then the carbon emission activity data can be obtained. For the parameter fitting method, a device carbon footprint report of the substation engineering can be obtained, and the carbon emission activity data of each stage of the substation engineering, including material consumption and energy consumption, can be extracted from the device carbon footprint report of the substation engineering by parameter matching. For the process tracing method, the carbon emission activity data of raw materials and process related to the production of building materials and equipment can be decomposed and traced, and then the carbon emission activity can be calculated step by step. In a preferred embodiment, the decomposition statistical method can be used to obtain the carbon emission activity data.
[0049] Step 230, the computing device 100 can construct a substation engineering carbon emission accounting model based on the carbon emission activity data of each stage of the substation engineering and the corresponding carbon emission factor value.
[0050] In the embodiments of the present application, the substation engineering carbon emission accounting model includes a procurement stage carbon emission accounting model, a construction stage carbon emission accounting model, and an operation stage carbon emission accounting model. That is, in step 230, the computing device 100 can construct the procurement stage carbon emission accounting model, the construction stage carbon emission accounting model, and the operation stage carbon emission accounting model based on the carbon emission activity data of each stage of the substation engineering and the corresponding carbon emission factor value.
[0051] Step 240, the computing device 100 can calculate the carbon emission of each stage of the substation engineering by using the substation engineering carbon emission accounting model, and can calculate the total carbon emission of the substation engineering based on the carbon emission of each stage of the substation engineering.
[0052] Specifically, the computing device 100 can calculate the carbon emission in the procurement stage, the carbon emission in the construction stage, and the carbon emission in the operation stage by using the procurement stage carbon emission accounting model, the construction stage carbon emission accounting model, and the operation stage carbon emission accounting model, respectively.
[0053] Further, the computing device 100 can obtain the total carbon emission of the substation project by adding the carbon emission in the procurement stage, the carbon emission in the construction stage, and the carbon emission in the operation stage. In other words, the total carbon emission of the substation project is the sum of the carbon emission in the procurement stage, the carbon emission in the construction stage, and the carbon emission in the operation stage.
[0054] According to the embodiments of the present application, when performing carbon emission accounting for the substation project, the procurement stage mainly considers the carbon emission of the raw material production link and the transportation link, and also includes the carbon emission caused by using construction machinery due to the removal of transportation obstacles. The construction stage mainly considers the carbon emission in each construction link such as the site leveling project, the foundation project, the building construction, the support installation, and the equipment installation and debugging. The operation stage mainly considers the carbon emission caused by heating, air conditioning, and lighting during the construction process.
[0055] It should be noted that the substation project construction involves the use of a large amount of construction materials (building materials). For the carbon emission accounting in the procurement stage, the carbon emission of the production link and the transportation link of each type of building material and equipment needs to be considered. The carbon emission of the transportation link is related to the transportation weight, the transportation distance, and the corresponding carbon emission factor value.
[0056] Based on this, in some embodiments, in step 230, the procurement stage carbon emission accounting model can be constructed in the following manner:
[0057] First, the types of building materials and the material consumption involved in the construction stage of the substation project can be counted based on the bill of quantities, and the average carbon emission factor value of each type of building material can be found based on the “Building Carbon Emission Calculation Standard” as the material production carbon emission factor value corresponding to the building material.
[0058] Subsequently, based on the material consumption of each type of building material and equipment production link in the substation project and the corresponding material production carbon emission factor value, a production link carbon emission accounting model can be constructed. The production link carbon emission accounting model is used to calculate the carbon emission of the production link. The production link carbon emission accounting model is specifically as shown in the following formula:
[0059]
[0060] In the formula, MP m,i is the material consumption of the i-th type of material in the production link of building materials and equipment; is the carbon emission factor value corresponding to the i-th type of material. In some embodiments, the material includes, for example, metal, concrete, masonry, cement, wood, etc.
[0061] Moreover, based on the average carbon emission factor values corresponding to the transportation distance, transportation weight, and unit energy consumption of transportation tools in the transportation links of various building materials and equipment in the substation project, a carbon emission accounting model for the transportation link can be constructed. The carbon emission accounting model for the transportation link is used to calculate the carbon emissions in the transportation link. The carbon emission accounting model for the transportation link is specifically shown as follows:
[0062]
[0063] In the formula, TD b,i and TD e,i are the transportation distances of the i-th type of building material and the i-th type of equipment respectively; TW b,i and TW e,i are the transportation weights of the i-th type of building material and the i-th type of equipment respectively; EF b,i and EF e,i are the average carbon emission factor values corresponding to the unit energy consumption of the transportation tools for the i-th type of building material and the i-th type of equipment respectively.
[0064] In some embodiments, the equipment in the substation project includes, for example, heavy-duty trucks, truck-mounted cranes, dump trucks, crawler single-bucket hydraulic excavators, crawler bulldozers, crawler cranes, wheeled loaders, mechanical vibratory rollers, motorized tipping cars, steel-wheel internal combustion rollers, distribution boxes, elevators, multi-connected air-conditioning central controllers, variable-frequency multi-connected central air-conditioning outdoor units, maintenance and repair equipment, explosion-proof axial fans, explosion-proof wall-mounted air-conditioning units, split floor-standing air-conditioners, fresh air unit indoor units, ceiling-embedded air-conditioning indoor units, computer room dedicated precision air-conditioning units, multi-connected air-conditioning central controllers, oil and SF6 treatment equipment, etc. The building materials in the substation project include, for example, neat cement slurry, cement mortar, mixed mortar, lime mortar, hemp mortar, cast-in-place concrete, quartz sand, iron parts and steel sections, round steel, h-shaped steel, aerated concrete blocks, standard bricks, etc.
[0065] Furthermore, based on the above carbon emission accounting model for the production link and the carbon emission accounting model for the transportation link, a carbon emission accounting model for the procurement stage can be obtained.
[0066] It should be understood that the carbon emissions in the procurement stage calculated using the carbon emission accounting model for the procurement stage include the carbon emissions in the production link and the carbon emissions in the transportation link.
[0067] In addition, considering the difficulty in data collection for accounting of carbon emissions in the building material transportation link, in some embodiments, the carbon emissions in building material transportation can be accounted for by using highway transportation and heavy gasoline trucks as the transportation tools based on the default transportation distance and mode set in the "Standard for Calculating Carbon Emissions of Buildings".
[0068] According to an embodiment of the present application, the construction and construction phase of the substation project includes the civil engineering link and the installation link (electrical equipment installation link), the civil engineering link includes building and structure construction, and the installation link includes electrical equipment installation, test and commissioning. In some embodiments, the buildings of the substation project are mainly divided into five categories: power generation buildings, substation buildings, power transmission buildings, auxiliary and supporting buildings, and special function buildings. Among them, the power generation buildings include thermal power stations, hydropower stations and new energy power station buildings. The structures include support and equipment foundation, firewall, emergency oil pool, cable channel, internal and external roads, fence and gate, retaining wall and slope protection, etc. In some embodiments, the civil engineering link mainly includes earthwork engineering, foundation treatment, support and equipment foundation construction, masonry engineering, reinforced concrete engineering, roofing engineering, decoration engineering, firewall engineering, and cable channel construction, totaling 9 links.
[0069] The carbon emissions in the construction and construction phase mainly come from the carbon emissions caused by the energy consumption of construction machinery used in the civil engineering link and the electrical equipment installation link of the substation project, as well as the energy consumption of the construction personnel's office and life. The energy consumption of the construction personnel's office and life mainly comes from the construction, operation and demolition process of the temporary buildings in the construction and construction phase (civil engineering link and installation link), among which electric energy is the main energy supply form.
[0070] Based on this, in step 230, the construction and construction phase carbon emission accounting model can be constructed by the following method: based on the number of shifts of various types of construction machinery used in the civil engineering link and the installation link of the substation project, the energy consumption per shift of various types of construction machinery, and the energy carbon emission factor value, as well as the area of temporary buildings in the civil engineering link and the installation link, the unit area carbon emission factor value of temporary buildings in the construction process, the unit area carbon emission factor value of temporary buildings in the demolition process, the unit area electric energy consumption (power consumption) of temporary buildings in the operation process, and the electric energy carbon emission factor value, to construct the construction and construction phase carbon emission accounting model.
[0071] The construction and construction phase carbon emission accounting model constructed according to the present application is used to calculate the carbon emissions in the construction and construction phase. The construction and construction phase carbon emission accounting model is specifically shown in the following formula:
[0072]
[0073] wherein CM i , CM j are the daily shift quantities of the i-th type of construction machinery used in the civil engineering stage and the j-th type of construction machinery used in the installation stage, respectively; d i , d j are the energy consumptions per daily shift of the i-th type of construction machinery and the j-th type of construction machinery, respectively; EF, EF j are the carbon emission factor values corresponding to the i-th type of construction machinery and the j-th type of construction machinery, respectively. S is the temporary building area, EF u is the carbon emission factor value per unit area of the temporary building in the construction process, EF R is the carbon emission factor value per unit area of the temporary building in the demolition process, P is the electric energy consumption per unit area in the operation process of the temporary building, and EF e is the carbon emission factor value of electric energy.
[0074] In some embodiments, the construction machinery can include diesel machinery and electric machinery, for example.
[0075] It should be understood that the carbon emissions of the construction stage calculated by the construction stage carbon emission accounting model include the carbon emissions caused by the energy consumption of various types of construction machinery used in the civil engineering stage and the installation stage, and the carbon emissions in the construction, demolition and operation processes of the temporary building.
[0076] In addition, considering the lack of original energy consumption data of the construction site of the substation engineering, in some embodiments, the carbon emissions can be calculated based on the bill of quantities and construction quota. Specifically, based on the “Electric Power Construction Engineering Budget Quota (2018 Edition)”, the types of construction machinery and the number of personnel shifts for each sub-item in the civil engineering and installation stages can be determined. Then, in combination with the “National Unified Construction Machinery Daily Shift Quota”, the types of energy and energy consumption per daily shift of various types of construction machinery can be determined.
[0077] In some embodiments, the carbon emissions of the operation stage of the substation engineering mainly come from the energy consumption in the aspects of heating, air conditioning and lighting. In step 230, the operation stage carbon emission accounting model can be constructed in the following manner: based on the electric energy consumption (power consumption) per unit time of the heating equipment in the substation engineering, the daily operation time of the heating equipment, the electric energy consumption per unit time of the air conditioning equipment, the daily operation time of the air conditioning equipment, the daily electric energy consumption of the lighting equipment, the daily operation time of the lighting equipment, the total number of days in the operation stage, and the carbon emission factor value of electric energy, the operation stage carbon emission accounting model is constructed.
[0078] The operation stage carbon emission accounting model constructed according to the present application is used to calculate the carbon emissions of the operation stage. The operation stage carbon emission accounting model is specifically shown in the following formula:
[0079]
[0080] In the formula, CS represents the carbon emission in the operation stage, F h,i represents the unit time electric energy consumption of the heating equipment; F c,i represents the unit time electric energy consumption of the air conditioning equipment; F l,i represents the unit time electric energy consumption of the lighting equipment; t h represents the daily operation time of the heating equipment; t c represents the daily operation time of the air conditioning equipment; t l represents the daily operation time of the lighting equipment; EF e represents the carbon emission factor value of the electric energy; n represents the total number of days in the operation stage.
[0081] It should be understood that the carbon emission in the operation stage calculated by the operation stage carbon emission accounting model includes the carbon emission generated by the heating equipment, the air conditioning equipment and the lighting equipment in the operation stage.
[0082] In some embodiments, the substation project can select a new 800kV substation project of a certain ultra-high voltage project in Shanxi Province to carry out carbon emission accounting analysis. The substation occupies an area of about 15.79 hectares in the fence, and the buildings in the station area include the main control communication building, the relay small room, the main transformer room, the station power room, etc., which adopt the reinforced concrete frame structure, and the total building area of the whole station is about 6136m 2 , of which the main control communication building is 2500m 2 . The 1000kV structure support and equipment support adopt the steel pipe lattice structure, the main transformer structure, and the 500kV structure adopt the steel pipe column and lattice steel beam structure; the rest of the equipment support adopts the steel pipe structure. The present application adopts 7 sets of 1000kV single-phase oil-immersed no-excitation voltage regulation autotransformer, and the weight of a single device is 398t. The equipment is transported to the construction site in the mode of combination of waterway and highway, and the rest of the equipment and construction materials are transported in the conventional transportation mode.
[0083] In addition, the reference measure list can be used as the substation construction project implemented by using the current mainstream construction technology, scheme and measure, and the energy consumption demand in the operation stage is satisfied by being connected to the power grid. On this basis, according to the national standards such as “Green Construction Evaluation Standard for Building Engineering” (GB / T50640) and “Green Construction Specification for Building Engineering” (GB / T50905), 6 low-carbon technologies are adopted, the low-carbon measure list and the strong low-carbon measure list are set, and different technical popularization rates are set for different measure lists according to the actual situation of the ultra-high voltage substation construction, as shown in Table 1.
[0084] Table 1 Technical popularization rate setting
[0085]
[0086] As shown in Table 1, in the source carbon reduction technology selection, the replacement ratio of cement and traditional concrete in the low-carbon measure list reaches 50%, and the strong low-carbon measure list reaches 100%; in the construction material transportation, the low-carbon and strong low-carbon measure lists are uniformly replaced by electric power transportation machinery. Secondly, the construction carbon reduction measures mainly focus on the electrification of construction machinery, and the low-carbon and strong low-carbon measure lists uniformly replace oil-fired construction machinery with electric construction machinery. Finally, due to the characteristics of active and passive technologies and site selection environment, the low-carbon measure list can set the promotion rates of passive energy-saving (natural lighting and ventilation) and active energy-saving technology (photovoltaic integration) to 20% and 25% respectively, and the strong low-carbon measure list sets them to 30% and 50%.
[0087] The PKPM-CES Industry is used to simulate and calculate the 800kV substation of the ultra-high voltage project through the bill of quantities combined with carbon emission factors and other data in a year as a cycle, and the carbon emissions of each stage can be obtained.
[0088] Figure 3 A schematic diagram of carbon emissions under three measure list scenarios according to some embodiments of the application is shown. From the diagram, it can be seen that the differences of the nine types of carbon emissions in the three stages under the three measure list scenarios of the baseline measure scenario, the low-carbon measure scenario and the strong low-carbon measure scenario. Figure 3 As can be seen, the differences of the nine types of carbon emissions in the three stages under the three measure list scenarios of the baseline measure scenario, the low-carbon measure scenario and the strong low-carbon measure scenario. Specifically, the procurement stage (production and transportation link) includes materials such as metal, concrete, masonry, cement and wood, the construction stage covers electric machinery and diesel machinery, and the operation stage includes heating, air conditioning and lighting equipment energy consumption.
[0089] Overall, the total carbon emissions under the baseline measure list, the low-carbon measure list and the strong low-carbon measure list are 228663.99, 126423.31 and 52181.66tCO2 respectively. Obviously, the application of low-carbon technology can significantly reduce carbon emissions.
[0090] In terms of stages, the carbon emissions of the procurement stage under the baseline measure list, low-carbon measure list, and strong low-carbon measure list were 190315.88, 96343.15, and 22104.39 tCO2, accounting for 83.23%, 76.21%, and 42.36%, respectively. The carbon emissions under the baseline measure list and low-carbon measure list scenarios accounted for a higher proportion, mainly due to cement and concrete, as the main control building adopts a reinforced concrete form, and a high proportion of cement and concrete is used in the procurement of building materials. In addition, due to the high carbon emissions of these two types of building materials, the procurement stage has the highest carbon emissions. The carbon emissions of the construction stage under the baseline measure list, low-carbon measure list, and strong low-carbon measure list were 38336.61, 30073.25, and 30073.25 tCO2, accounting for 16.77%, 23.79%, and 57.63%, respectively. Due to the low mechanical bench quantity of the main control building construction and the existence of a certain proportion of electric machinery, the carbon emissions of the construction stage are at a medium level. The carbon emissions of the operation stage under the baseline measure list, low-carbon measure list, and strong low-carbon measure list were 11.50, 6.90, and 4.02 tCO2, accounting for 0.01% each. Due to the fact that this report only simulates the ten-year period and does not consider the power consumption of auxiliary systems, depreciation, and other factors, the main carbon emission source of the operation stage is household electricity, accounting for a low proportion.
[0091] To explore the carbon emission reduction effect brought about by the use of low-carbon technology, the carbon emissions of the low-carbon measure list and strong low-carbon measure list were plotted against the baseline measure list carbon emissions, as shown in Tables 2 and 3.
[0092] Table 2 Carbon emission changes of low-carbon and strong low-carbon measure lists
[0093]
[0094] Table 3 Carbon emission change percentages of low-carbon and strong low-carbon measure lists
[0095]
[0096]
[0097] Tables 2 and 3 show that, regarding the changes in carbon emissions caused by various materials, the most significant positive changes (carbon reduction) are seen in brick and stone, cement, timber, and diesel machinery. The former's changes are primarily due to the high demand for cement during construction and operation, and the significant reduction in unit carbon emissions after replacing it with kaolin cement. The latter's changes are due to the large number of shifts in diesel machinery and the significant difference in carbon emission factors between fuel oil and electricity. The least significant positive changes (carbon reduction) are seen in heating and air conditioning during operation. This is partly because total carbon emissions are low during operation, and partly because heating and air conditioning equipment are basic necessities, making it difficult to reduce usage. Furthermore, the replacement of some diesel machinery with electric machinery has resulted in a counter-trend increase in carbon emissions from electric machinery, i.e., a negative change (carbon increase).
