变电站作为城市供配电系统的重要枢纽,在建设、安装和运维过程中会造成大量温室气体排放,通过对变电站建筑全生命周期碳排放进行研究,可明确变电站建筑的碳排放特点,并采取有针对性的节能减碳技术措施,从而降低能源消耗,保护生态环境.以浙江安吉110 kV城北变电站建设方案为例,对其全生命周期碳排放量进行计算,从平面布置、围护结构设计、结构设计、暖通设计、模块化设计5 个方面进行减碳优化,并与原方案进行对比分析.研究表明,整体优化后全生命周期总减碳量为1 619 362.52 kgCO2e,减碳率72.32%,其中地基与基础设计优化和暖通设计优化是全生命期减碳总量较大的措施,减碳量分别为 650 400.80 kgCO2 e和440 897.60 kgCO2e.
As an essential hub of urban power supply and distribution systems,substations cause a great amount of greenhouse gas emissions during construction,installation,operation,and maintenance.By studying the life-cycle carbon emissions of substation buildings,the carbon emission characteristics of substation buildings can be figured out,thus targeted energy-saving and carbon-reducing technical measures can be taken to reduce energy consumption and protect the ecological environment.The construction plan of Zhejiang Anji 110 kV Chengbei substation is analyzed,calculating its whole life cycle carbon emission,optimizing the carbon reduction in five aspects,including the plan layout,envelope design,structural design,HVAC design,modular design,and comparing with the original plan.The result shows that the total life-cycle carbon reduction with the overall optimization is 1 619 362.52 kgCO2e,the carbon reduction rate is 72.32%,among which the optimization of foundation and footing design and the optimization of HVAC design are the measures with larger total life-cycle carbon reduction,with carbon reduction of 650 400.80 kgCO2e and 440 897.60 kgCO2e respectively.
