摘要
在分析、对比国内外数据中心柴油发电机组备用电源母线配电系统几种配电方式基础上,探讨环形母线配电在数据中心柴油发电机组备用电源配电系统中应用的技术特点和优势。重点探讨如何实现环形母线配电系统的继电保护难点问题,通过采用母线差动、多段复合过流保护等保护方式,实现故障的快速甄别与切除,达到高等级数据中心配电系统并行可维护、容错和自愈能力要求。
Based on the analysis and comparison of several power distribution modes in the bus distribution system for the standby power supply of the diesel generator unit in the data center,the technical characteristics and advantages of the ring bus distribution in the standby power supply for the diesel generator unit in the data center are discussed.This paper focuses on the difficulties in how to realize the selective protection of the ring bus distribution system.Through the line differential protection multi⁃segment composite overcurrent protection and other protection methods,the rapid identification and removal of faults can be realized to meet the requirements of parallel maintainability,fault tolerance and self⁃healing ability of the distribution system of high⁃level data center.
