Abstract

Carbon emission calculation during power transmission and substation construction provides valuable insights into the trend of carbon emissions and the development of low-carbon power grids. In this regard, this study divides the power transmission and substation construction process into production, transportation, and construction stages based on the sources of carbon emissions and employs a life cycle assessment to calculate the total carbon emissions using the carbon emission factor method for typical 500 kV projects. The results show that in the construction process the production stage contributes the most carbon emissions, with material and equipment production for power transmission accounting for 78% and 14% of the total emissions, respectively. The transportation and construction stage contribute 1% and 7% of the total emissions, respectively. For substations, material and equipment production contribute 67% and 30% of the total emissions, respectively. The transportation and construction phases contribute 1% and 2% of the total emissions. Through the qualitative and quantitative analysis of the carbon emission results, the construction scale and the topography and geology have significant impacts on carbon emissions from power transmission and substation projects. Finally, some targeted recommendations for carbon emission reduction for power transmissions and substations are proposed based on the influencing factors of each stage of the construction.

采用碳排放系数法核算典型 500 千伏输变电站建设过程中的碳排放量

输变电建设过程中的碳排放计算可为碳排放趋势和低碳电网的发展提供有价值的启示。为此，本研究根据碳排放源将输变电建设过程划分为生产、运输和施工阶段，并采用生命周期评估方法，利用碳排放因子法计算典型 500 千伏项目的总碳排放量。结果表明，在建设过程中，生产阶段的碳排放量最大，输电材料和设备生产分别占总排放量的 78% 和 14%。运输和施工阶段分别占总排放量的 1%和 7%。对于变电站，材料和设备生产分别占总排放量的 67% 和 30%。运输和施工阶段的排放量分别占总排放量的 1%和 2%。通过对碳排放结果的定性和定量分析，建设规模和地形地质对输变电工程的碳排放有显著影响。最后，根据施工各阶段的影响因素，提出了一些有针对性的输变电工程碳减排建议。
