摘要:

在“双碳”战略目标下,核算输变电工程的碳排放水平可为电力工程的减碳工作提供重要数据参考。当前,输变电工程碳排放核算领域面临着标准缺失与研究基础薄弱的问题,亟待建立精细化方法和模型。面向输变电工程供应链上游减碳的应用场景,首先,从研究对象和核算边界两方面界定了碳排放核算范围;其次,梳理了关键设备与材料在原材料获取与生产制造环节的碳排放活动,研究了工程前期数据受限情况下的活动量获取与转换方式,构建了输变电工程关键设备与材料的碳排放核算模型;最后,面向某特高压直流输变电工程,基于在初设阶段的有限数据源,核算了7种关键电力设备与材料在原材料获取与生产制造环节的碳排放。结果表明,导线、杆塔材料和变压器是输变电工程关键设备与材料的主要碳排放来源,应聚焦这3类设备在原材料与制造工艺方面的碳排放,推进电力设备与材料的降碳研究。

Abstract:

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.
