数据中心RR架构分析及应用实践

Analysis and Application Practice of RR Architecture in Data Center

从理论上分析4种中低压RR供电架构具体形式和特点。从建设成本、可靠性、供电效率等方面,对比分析数据中心分布式柴油发电机中压RR架构与2N架构技术特点。针对数据中心分布式柴油发电机中压RR架构存在的电气隔离等问题提出相应的运维保障措施,并介绍一种可实现A、B两路电源电气隔离的RR架构。

Specific forms and characteristics of four MV and LV RR power supply architectures are analyzed theoretically. The technical characteristics of MV RR architecture and 2N architecture of distributed diesel generator are compared and analyzed in terms of construction cost, reliability and power supply efficiency. In this paper,the corresponding operation and maintenance guarantee measures are put forward and an RR architecture that can realize the electrical isolation of two power sources are introduced for the electrical isolation problems existing in the MV RR architecture of distributed diesel generators.
