随着数据中心能耗的持续增加，人们正在考虑各种可以提高现有和未来数据中心效率的方案。一种方法是在DC配电系统上操作设施。这可以消除中间DC/AC和AC/DC功率级，从而提高整个数据中心功率输送系统的效率。虽然DC数据中心的好处已经通过演示和分析得到了明确的证明，但分析将影响其实际实施的问题至关重要。电源质量就是这样一个问题，由于其与数据中心可靠性和可靠性的直接联系，其重要性不容忽视。本文讨论了直流数据中心可能发生的各种电能质量干扰，它们对系统性能的影响，以及减轻此类干扰必须考虑的设计考虑因素。
As data center energy consumption continues to increase, various options are being considered that could improve the efficiency of existing and future data centers. One way is to operate the facility on a DC distribution system. This can eliminate intermediate DC/AC and AC/DC power stages, thereby improving the efficiency of the entire data center power delivery system. While the benefits of a DC data center have been clearly proven through demonstrations and analysis, it is of paramount importance to analyze issues that will impact its practical implementation. Power quality is one such issue whose importance cannot be dismissed due to its direct connection to datacenter reliability and uptime. This paper discusses the various power quality disturbances that can occur in DC data centers, their impact on system performance, and design considerations that must be taken into account for mitigating such disturbances.
