大数据, 2023 作为算力承接地，西部地区拥有丰厚的自然资源禀赋，需充分发挥其在能源、气候等方面的优势。“东数西算”背景下，数据中心急需对算力转移过程的碳减排效益进行量化分析。在考虑可再生能源、气候因素和传输过程3个影响因素的情况下，构建了数据中心工作负载转移的碳排放量核算模型，以“东数西算”八大节点为例进行算例分析。结果发现，相较于可再生能源和气候因素所减少的碳排放量，传输过程造成的额外碳排放量微乎其微，在仅考虑前两者的情况下，每转移1 kW·h的工作负载，碳排放量可减少0.053~0.344 kg ...

12 kV气体绝缘断路器柜在原材料获取阶段和制造阶段碳排放计算与对比分析
Gaoya dianqi, 2023 产品碳足迹是指产品在整个生命周期中对环境产生的影响，目前高压开关设备全生命周期碳足迹核算已成为高压开关领域的一个热点研究问题。文中以12 kV气体(干燥空气和SF6)绝缘环网开关设备中的断路器柜为研究对象，利用碳排放当量计算公式进行产品原材料获取阶段和制造阶段的计算，并对两种断路器柜计算结果进行对比分析。在原材料获取阶段干燥空气绝缘断路器柜比SF6气体绝缘断路器柜碳排放当量多25%(不计入绝缘气体)，在生产制造阶段两者的碳排放量基本相当。计入SF6气体碳排放量后两者的差异巨大 ...
