基于数据中心碳中和大背景和降低PUE的刚性需求,本文提出了以10kV能量路由器为核心技术的柔性供电系统方案。该方案解决目前数据中心供电系统不能大规模接入光伏、储能的问题,大幅减小数据中心电网电能消耗,提高数据中心运营效益;优化数据中心供电系统架构,利用储能系统替代长期浮充状态的应急电源蓄电池组,解决单体电池开路隐患、蓄电池组运维工作量大的问题;通过电能转换装置模块化几余设计解决模块可靠性、运维方便性问题:通过柔性控制解决系统电压、电流、功率平衡问题,解决电力电子模块工作效率问题。

Based on the background ofcarbon neutralization and the rigid demand of PUE reduction in data centers,this paper proposes a flexible power supply system scheme with 10kV energy routers as the core technology.The scheme solves the problem that the current data center power supply system cannot be connected to photovoltaic and energy storage on a large scale.This greatly reduces the power consumption of the data center grid and improves the operating efficiency of the data center.Optimizing the power supply system architecture of the data center by replacing the emergency power battery packin the long-term floating state with the energy storage system,so as to solve the hidden danger of open circuit of a single battery and the heavy workload of battery pack operation and maintenance The modular redundancy design of the electric energy conversion device solves the problems of module reliability and convenience of operation and maintenance The balances of system voltage,current,and power are solved through flexible control,and the working efficiency of power electronic modules is solved.
