Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission accounting for power systems, and more specifically, to a method, device and medium for carbon emission accounting during the life cycle of a power transmission and transformation project. Background Art

[0002] Carbon emissions refer to the general term for greenhouse gas emissions of the research object. Accurate measurement of carbon emissions is the basis for achieving the "dual carbon" goal. Accurate and detailed carbon emissions data can provide an important basis for the formulation of relevant policies for the power system and for conducting evaluation and assessment work. As the main source of global carbon emissions, the energy industry needs to focus on carbon emission accounting technology. Among them, carbon emission accounting in the power sector is the top priority. According to data released by the International Energy Agency in 2020, the growth rate of carbon emissions involving electricity is the fastest among all industrial sectors.

[0003] The life cycle assessment method is a method for quantitatively analyzing the environmental impact caused by the product production process. After determining the accounting object and accounting boundary, the calculation is completed by collecting data on the entire life cycle of the product and calculating the data by characterization. Among them, carbon emissions are one of the environmental impacts analyzed by the life cycle method.

[0004] In addition, there are currently no relevant standards for the accounting of carbon emissions from power transmission and transformation on the grid side of the power system, and the technology is not perfect. The determination of carbon emission objects for different projects, the definition of accounting boundaries, the formulation of data collection sequence principles, and the engineering carbon emissions summary model are not yet mature. Power transmission and transformation projects in the power system urgently need to solve the problem of carbon emissions accounting throughout the life cycle and propose a guiding carbon emissions accounting method.

[0083] Figure 1 1 is a flow chart of a method for calculating carbon emissions during the life cycle of a power transmission and transformation project provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 1 As shown, the carbon emission accounting method 100 for the life cycle of a power transmission and transformation project includes the following steps:

[0084] Step 101, specifying carbon emission accounting objects in the life cycle stage of the power transmission and transformation project, and determining the accounting boundary model of each carbon emission accounting object;

[0089] Specifically, the present invention specifies the carbon emission accounting process, accounting boundaries, accounting methods, data collection and other contents of the power system transmission and transformation project. Based on the "modularization" principle, the boundaries of the entire life cycle of the power system transmission and transformation are divided into the survey and design stage, the material acquisition stage, the construction and installation stage, the operation and maintenance stage, and the dismantling and recycling stage. The data collection principles for carbon emission activities of the transmission and transformation project are proposed, a carbon emission model for each stage is established, and a summary model for the project carbon emission accounting is proposed. The present invention provides a method for carbon emission accounting in the life cycle of a transmission and transformation project to solve the technical problem of the lack of carbon emission accounting methods in the life cycle of a power system. The steps are:

[0098] Select activities that have a significant impact on the carbon emissions of power transmission and transformation projects and should be kept independent of each other for measurement;

[0099] Activities that account for a small proportion of total life cycle carbon emissions, are technically impossible to quantify or the cost of quantification is too high may not be included in the accounting.

[0100] Further, in step 1, refer to Figure 2 As shown in the figure, the life cycle stages of power transmission and transformation projects include design stage, material stage, construction stage, operation and maintenance stage, and dismantling and recycling stage.
