摘要
数据中心市电柴发切换系统是为保障市电电源故障时系统顺利切换到柴油发电机系统供电状态,以及市电恢复后系统顺利从柴油发动机供电状态切换到市电供电状态而设置的一套装置,是保障数据中心供电可靠性的关键设施。本文对数据中心10kV市电与柴油发电机系统切换的控制要求、常见的3种投切方式、切换的控制逻辑以及3种方式的优缺点进行了详细的分析和探讨。
The diesel power generation switching system in the data center is to ensure that the system switches smoothly to the power supply state of the diesel generator system when the utility fails, and a set of devices are set up for the system to switch smoothly from the diesel engine power supply state to the utility entrances state after the utility entrances is restored. it is the key facility to ensure the power supply reliability of the data center. In this paper, the control requirements, three common switching modes, switching logic and the advantages and disadvantages of the three switching modes of 10KV power and diesel generator system in data center are analyzed and discussed in detail.
