| description | Under “dual-carbon” goals, the carbon emission accounting for power transmission and transformation projects can provide important data reference for carbon reduction of power projects. At the present stage, the field of carbon emission accounting in power transmission and transformation projects is facing the problems including the lack of standards and weak research foundation, thus it is significant to establish specific methodology and models. This paper is oriented to the application scenario of upstream carbon reduction in the supply chain of power transmission and transformation projects. Firstly, the paper defines the scope of carbon emission accounting from perspectives of carbon accounting objects and system boundary; secondly, the paper analyzes the carbon emission activities of key equipment and materials during raw material acquisition and manufacturing stages, researches the way of collecting and converting activity data with limited raw data from the pre-engineering stage, and constructs carbon emission accounting models for key equipment and materials in power transmission and transformation projects; finally, the paper conducts a case study for an ultra-high voltage direct current transmission and transformation project, and calculates the carbon emissions of seven key electric equipment and materials during raw material acquisition and manufacturing stages based on the limited data sources from the preliminary design stage. The research results show that wires, tower materials and transformers are the main components of the total carbon emissions, thus it is essential to focus on carbon emissions of the equipment, and promote the research on carbon reduction in electrical equipment and materials. |
