Zone protection approach of data center system reliability and power quality

摘要

A critical analysis of power quality and power reliability in data centers is important as steppingstone for improving data center operation efficiency. All data center standards such as, Uptime Tier Classification, TIA-942, BICSI 002, BITKOM, and eN 50600, are defined system reliability design by topology but not mentioned on power quality. Most of topology defines by a single line diagram of power distribution systems (PDS). The PDS design approach is using a coherent zone protection mechanism. This mechanism is tried to get rid of single points of failure by applying redundant topology such as N (by N ≥ 1), N+1, 2N, 2(N+1), and 2N+2N through PDSs. This paper describes the zone protection approach of system reliability and power quality design for Tier 4 data centers. This paper was conducted design analysis of power distribution systems (PDS) from 8 (Tier 3) data centers and 2 (Tier 4) data centers while compared 5 data center standards subject to how to build the highest reliability and harmonic control of data center through zone protection as a recheck point. The results of zone protection analysis proposes a new practical topology of PDS in data center that can be practically deployment in order to improve the overall power quality and reliability of the data centers.
