[0047] Step B2: sum up the carbon footprint calculation models corresponding to each target process in the target stage to determine the carbon footprint calculation model corresponding to the target stage.

[0048] Specifically, for each target stage in the life cycle of electrical equipment, determine the influencing factors related to the carbon emissions generated in each target process included in the target stage, such as the carbon emissions of the equipment used to make the electrical equipment, the carbon emissions of the raw materials of the electrical equipment, and the carbon emission factors of the electrical equipment. At the same time, determine the carbon footprint accounting model used in each target process based on the influencing factors of carbon emissions in each target process. Then, add up the carbon footprint accounting models used in each target process included in the target stage, and use the added carbon footprint accounting model as the carbon footprint accounting model for the target stage.

The technical solution of this embodiment further optimizes the target stages in the life cycle of electrical equipment and the target processes in each target stage of the above embodiment on the basis of the technical solution of the above embodiment. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 3 As shown, the method includes:

[0071] S201. Determine basic information and process flow of electrical equipment, and determine the carbon accounting system boundary in the life cycle of the electrical equipment based on the basic information and process flow.

[0072] In the embodiment of the present invention, the basic information of the electrical equipment may include the type, model, purpose, material composition, material properties and production process of the electrical equipment. The process flow of the electrical equipment may include the design, parts manufacturing, assembly, factory testing, on-site installation, operation monitoring, maintenance operation and decommissioning of the electrical equipment.

[0073] Specifically, determine the electrical equipment that needs to calculate carbon footprint, such as transformers, cables, switchgear, etc., and determine the type of electrical equipment and the functional unit of carbon footprint accounting. At the same time, determine the basic information of the electrical equipment, such as material composition, material properties, and production process, and determine the process flow of the electrical equipment based on the basic information. Furthermore, determine the scope involved in the carbon emission accounting of electrical equipment based on the basic information and process flow of the electrical equipment, and use it as the boundary of the carbon accounting system in the life cycle of the electrical equipment.

[0075] Specifically, based on the life cycle assessment method and according to the carbon accounting system boundary and process flow of electrical equipment, various target stages related to the carbon footprint of electrical equipment and various target processes included in each target stage are identified.

[0077] As an option, after constructing a calculation process tree with the target stage and the target process as nodes, the method for determining the carbon footprint of electrical equipment further includes the following steps D1-D2:

[0078] Step D1: construct node codes for each node in the accounting process tree.

[0079] Step D2: Establish a node database and store the associated data of each node in the accounting process in the node database; wherein the associated data of the node includes the node code, the node name, the parameters in the carbon footprint accounting model corresponding to the node, the identification code of the associated data and the carbon emissions corresponding to the node.

[0080] Specifically, corresponding node codes are established for each target stage and each target process represented by each node in the accounting process tree of electrical equipment, for example, the node code corresponding to the raw material acquisition stage is 001. At the same time, a corresponding node database is established for each node, and the node database stores the associated data related to the carbon footprint accounting of each node. Among them, the associated data may include the node code, the node name, the parameters in the carbon footprint accounting model corresponding to the node, the identification code of the associated data, and the carbon emissions corresponding to the node. The identification code of the associated data corresponds to the data in the node and can be expressed as a digital code, a QR code, a barcode, or any identification that can ensure traceability. Exemplarily, when the identification code of the associated data is expressed in a digital code, the first three digits can be the corresponding node code, and the fourth to sixth digits can be the serial number of the data related to the node. A corresponding node database is established for each node to optimize the management of node-related data, enhance the ability of data traceability, and effectively connect the associated data of each node through the identification code of the associated data to ensure the consistency and queryability of the data.

[0085] Step E2: Display the accounting process tree on the visual interface, and display the node number of each node and the carbon emission amount corresponding to the node at each node.

[0086] Specifically, after the carbon emissions corresponding to each node in the accounting process tree are calculated based on the carbon footprint accounting model and the actual data corresponding to each parameter in the carbon footprint accounting model, the carbon emissions corresponding to each node are stored in the associated data in the node database corresponding to each node. At the same time, the accounting process tree of electrical equipment can be displayed on the visual interface, and the node number and the carbon emissions corresponding to the node can be displayed at each node in the accounting process tree.

At the same time, according to the node exceeding the preset carbon emissions threshold and the node associated with the node in the accounting process tree, the target stage where the carbon emissions do not meet the requirements is determined. Then, the associated data of the target stage that does not meet the requirements is queried in the node database, and the target associated parameters that cause the carbon emissions of the target stage to not meet the requirements are determined.

[0095] Step G2: for each node in the updated accounting process tree and the pointing relationship between the nodes, determine the carbon emissions corresponding to each node in the accounting process tree according to the carbon footprint accounting model and actual data.

[0096] Specifically, for the accounting process tree of electrical equipment displayed on the visual interface, the accounting process tree can be modified and updated according to the user's change operation. Exemplarily, the nodes in the accounting process tree can be added, deleted, moved, or the pointing relationship between the nodes can be adjusted according to the user's change operation. Furthermore, for the modified and updated accounting process tree, the corresponding updated carbon footprint accounting model and the actual data corresponding to each parameter in the carbon footprint accounting model are used to calculate the carbon emissions corresponding to each node in the updated accounting process tree.

[0097] As an option, the method for determining the carbon footprint of electrical equipment also includes the following steps H1-H2:

[0099] Step H2: Obtain the associated data of each node in the accounting process tree, fill in the carbon footprint report template based on the associated data, and form a carbon footprint report.

[0100] In the embodiment of the present invention, the carbon footprint report refers to a report showing the carbon emissions of each target stage and each target process in the life cycle of the electrical equipment. The carbon footprint report template refers to a report template pre-built for the carbon footprint report of the electrical equipment.

[0101] Specifically, the report format and layout of the carbon footprint report of electrical equipment are determined according to the needs of users to form a carbon footprint report template. Then, the associated data of each node is obtained from the node database corresponding to each node in the accounting process tree of electrical equipment, and the associated data of each node is filled in the carbon footprint report template to form a carbon footprint report.

[0102] The technical solution of the embodiment of the present invention determines the basic information and process flow of electrical equipment, and determines the carbon accounting system boundary in the life cycle of electrical equipment based on the basic information and process flow; determines each target stage in the life cycle of electrical equipment and the target process in each target stage based on the carbon accounting system boundary and process flow, thereby realizing the determination of each target stage and each target process in the life cycle of electrical equipment based on the basic information and process flow of electrical equipment, thereby ensuring the comprehensiveness and continuity of the carbon footprint accounting process of electrical equipment; constructs an accounting process tree using the target stage and target process as nodes, thereby realizing the life cycle of electrical equipment through the accounting process tree.

[0128] E=E 原材料 +E 生产 +E 运输 +E 使用 +E 焚烧 ;

[0129] If the carbon emissions reduced by recycling electrical equipment are taken into account, the carbon footprint accounting model for the life cycle of electrical equipment is:

[0130] E=E 原材料 +E 生产 +E 运输 +E 使用 +E 处置 .

[0131] S305: Construct a calculation process tree based on each node of the electrical equipment and the input-output relationship of each node.

[0138] Specifically, the actual data of the life cycle of electrical equipment is substituted into the carbon footprint accounting model for calculation, so as to obtain the carbon emissions of electrical equipment at each target stage in the entire life cycle, and the carbon emissions of each target stage are summarized to obtain the total carbon emissions of electrical equipment. At the same time, the carbon emissions of each node are stored in the corresponding node database to facilitate data organization and management, as well as subsequent data analysis and tracing.

[0141]

[0142] S307. Based on the accounting process tree and node database of electrical equipment, conduct a comprehensive analysis of the accounting results, and trace back to identify and locate the factors affecting the carbon footprint.

[0143] Specifically, the calculation results of carbon emissions are analyzed in detail, the carbon emissions of each node are clarified, and the contribution of each node's carbon emissions to the total carbon emissions is evaluated. Furthermore, according to the identification code of the associated data, the specific production link and data source can be quickly located, its carbon emissions can be analyzed, and reverse tracing can be performed based on the process tree to identify the specific factors that lead to high carbon emissions.

[0144] S308. Based on the analysis results, propose emission reduction strategies.

[0145] Specifically, emission reduction strategies include technical emission reduction strategies and management emission reduction strategies. Among them, technical emission reduction strategies include: optimizing the design of electrical equipment, adopting lightweight design, reducing material usage and weight; introducing advanced production processes and equipment to improve energy efficiency; promoting the use of renewable energy such as solar energy and wind energy to replace traditional fossil energy; strengthening the classification, recycling and reuse of waste to reduce resource waste and environmental pollution.

[0146] Management emission reduction strategies include: establishing a carbon emission management system, formulating carbon emission management policies and systems, and clarifying emission reduction targets and responsibilities; implementing energy audits and energy efficiency assessments, optimizing energy use structure, and reducing energy consumption; and promoting suppliers to adopt low-carbon production methods to reduce carbon emissions in the supply chain.

[0147] For example, the emission reduction suggestions for the above GIS equipment are as follows: the carbon footprint of GIS equipment is mainly distributed in the upstream raw material acquisition stage, and the main components of upstream emissions are the production of raw materials such as aluminum alloy, cast aluminum silicon magnesium alloy, and carbon steel. Therefore, the focus of carbon emission reduction for GIS equipment is on the upstream stage. Furthermore, for the raw materials in the upstream stage, product carbon emission reduction can be achieved through the following ways: from the product design level, under the premise of achieving the same product performance, the composition of the product should be replaced with raw materials with low carbon footprint or high recycling rate as much as possible; green procurement, when purchasing raw materials, screen and give priority to purchasing from suppliers who implement effective carbon emission reduction measures in the production process; improve material utilization, by optimizing production processes and improving manufacturing precision, reduce raw material waste, and improve the effective utilization of materials.
