数据中心电能利用效率计量方法研究
Study on power usage effectiveness metering methods of data centers
摘要：
结合国家标准和计量科学方法的要求,从计量边界选择、点位设置、仪表管理、体系建设、数据采集和处理5个关键因素介绍了目前数据中心电能利用效率(PUE)计量存在的问题,并给出了关联要素的实施建议。通过实际数据中心案例,分析了PUE计量过程,以及基于能效计量如何实现节能降碳运行,为后续数据中心PUE计量和数据利用提供参考。
Abstract：
Based on national standards and metrological method requirements, this study examines current issues in power usage effectiveness (PUE) metering for data centers. The analysis covers five key elements: metering boundary selection, instrument placement, meter management, system framework, and data acquisition and processing. Practical recommendations are provided for each element. Using an operational data center case, this paper demonstrates the PUE metering process and shows how energy efficiency measurements enable energy conservation and carbon reduction. These findings thus serve as a practical reference for improving PUE measurement and data utilization in data centers.
