Description

供电控制方法及装置 技术领域
本文涉及但不限于通信领域，尤指一种供电控制方法及装置。
背景技术
在云计算席卷全球、云计算产业发展迅速的背景下，建设绿色数据中心、实现节能减排成为了近年来学术界和产业界关注的话题之一。在相关技术中，数据中心中的信息技术(IT，Information Technology)设备大多为每一台IT设备均需通过市电和高压直流输电(high-Voltage direct current，简称为HVDC)同时供电，在这种供电模式下，供电效率实质上是比较低的，且能耗较大。因为在电源给每一台IT设备供电时，所承担的负载率在80％左右时，电源的供电效率可以达到最高。然而采用市电和高压直流输电HVDC两个供电电源同时为每一台IT设备供电时，每一供电电源将均分每一台IT设备的负载，进而使得每一电源所承担的负载率将下降至50％左右，但是鉴于可靠性的考虑，每一IT设备的供电电源设计容量往往留取的余量较大，因此采用市电和高压直流输电HVDC两个供电电源同时为每一台IT设备供电时，每个电源所承担的负载率还达不到30％，造成电源的供电效率降低，能源浪费较大。
针对相关技术中，数据中心每一IT设备采用市电和高压直流输电同时供电的方式所导致的供电效率低的问题，尚未提出有效地解决方案。
