随着国民经济和国家信息化建设的快速发展、数据时代的到来以及互联网的快速发展,促使互联网数据中心迅速崛起。加强互联网数据中心直流电源运行节能的优化管理,是响应国家节能减排号召,合理调整并优化布局建设资源节约型社会的迫切需要。当前面临着降低数据中心总能源消耗、降低成本的巨大困难。为提高直流电源在运行中对能源的利用率,开展数据中心直流电源运行能耗优化方法的设计研究。直流电源母线与数据中心接口单元包括能源接口、DC/DC接口、变换器接口,需根据具体情况进行接口单元的主动调控;通过直流电源运行的系统级控制与能量管理,进行直流电源运行能耗优化,实现优化方法的设计。以某地区大型能源数据中心为例,设计对比实验,实验结果表明:设计的方法应用效果良好,优化后不仅可以控制电源运行单位时间内的能耗,还可以提高电源在运行过程中对能源的平均利用率,解决数据中心直流电源运行管理中存在的高耗能问题。

With the rapid development of the national economy and national information construction,the arrival of the data age and the rapid development of the Internet,the Internet data center has risen rapidly.Strengthening the optimal management of energy saving in DC power supply operation of Internet data center is an urgent need to respond to the call of national energy conservation and emission reduction,rationally adjust and optimize the layout of building a resource-saving society.At present,it is facing great difficulties in reducing the total energy consumption and cost of the data center.In order to improve the energy utilization rate of DC power supply in operation,the design and research of energy consumption optimization method for DC power supply operation in data center are carried out.The interface unit of DC power bus and data center includes energy interface,DC/DC interface and converter interface.According to the specific situation,the active control of the interface unit is carried out.Through the system-level control and energy management of DC power supply operation,the energy consumption of DC power supply operation is optimized,and the design of optimization method is realized.Taking a large energy data center in a certain area as an example,a comparative experiment is designed.The experimental results show that the design method has a good application effect.After optimization,it can not only control the energy consumption per unit time of power supply operation,but also improve the average utilization rate of energy during the operation of power supply,the high energy consumption problem in the operation and management of DC power supply in data center is solved.
