双碳背景下变电站全生命周期碳排放管理研究

esearch on the Lifecycle Carbon Emission Management of Substations under the“Dual Carbon”Background

变电站作为电力行业中的重要一环,在落实电力行业“双碳”战略目标中担负着重要角色,建设低碳变电站是未来的发展趋势,对“双碳”目标的实现以及绿色可持续发展具有重要意义。本文在系统梳理与深入分析变电站全生命周期碳足迹的基础上,结合变电站工程的自身特点,分析碳排放计算边界与碳排放核算方法,对其全生命周期碳排放进行计算。研究发现:变电站运行阶段的碳排放量占比最大达到75%,通过实施供能替代、运行优化、设备降碳、建筑节能等降碳技术改造,将显著减少变电站全生命周期的碳排放量。基于此,应注重设计阶段对变电站全生命周期碳排放的核算,建立碳管理信息系统实现碳足迹追踪,根据碳减排潜力科学选择降碳方案。

Substations,as a crucial component of the power industry,play a vital role in fulfilling the“dual carbon”strategic objectives of the power sector.Constructing low-carbon substations is the future development trend and holds significant importance for achieving“dual carbon”goals and promoting green and sustainable development.This paper,based on systematically organizing and deeply analyzing the carbon footprint throughout the lifecycle of substations and considering the unique characteristics of substation projects,analyzes the boundaries of carbon emission calculations and the methods for carbon accounting,and calculates the total lifecycle carbon emissions of substations.The research finds that carbon emissions during the operation phase of substations account for up to 75%of the total.Implementing carbon reduction technologies such as energy supply substitution,operational optimization,equipment decarbonization,and building energy conservation will significantly reduce the total lifecycle carbon emissions of substations.Based on this,it is important to focus on accounting for the carbon emissions of substations throughout their lifecycle during the design phase,establish a carbon management information system to track carbon footprints,and scientifically select decarbonization strategies based on carbon reduction potential.
