具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
图1是一种数据中心供电电路的示意图。
不间断电源(uninterruptible power system/uninterruptible power supply,UPS)可以使负载维持正常工作并保护负载软件、硬件不受损坏。当输入正常时,UPS输入电压稳压后供应给负载使用,同时它还向电池充电。UPS的输入可以是直流电(如高压直流输电(high voltage direct current,HVDC)或48伏特(volt,V)电源产品等)或交流电。如果UPS的输入是市电,此时的UPS就是一台交流式电稳压器。当输入中断(事故停电等)时,UPS立即利用电池的直流电能为负载供电。例如,UPS可以通过逆变器切换转换的方法向负载继续供应220V交流电。
数据中心(data center)是全球协作的特定设备网络,用于在因特网(Internet)网络中的信息技术(information technology,IT)设备上传递、加速、展示、计算、存储数据信息。IT设备是指利用信息技术对信息进行处理的设备。IT设备例如可以是服务器等。
为了保证可靠性,中大型数据中心一般为2N设计,参见图1,可以为一个服务器提供两个完全相同的供电模块。供电模块110中,电池113与UPS 111连接,市电经过变压器112与UPS 111连接。供电模块120中,电池123与UPS 121连接,市电经过变压器122与UPS 121连接。IT设备140为UPS 111和UPS 121的负载。
采用上述方式,供电系统的利用率低,理论上,相对于供电系统能够提供的最大功率,功率的最大实际利用率只有50%。
数据中心中,每个IT设备的平均功率并不高,但当业务突增时,IT设备的功率上升,可能出现峰值功率,峰值功率甚至可以达到平均功率的数倍。为了确保服务器的正常运行,必须保证为服务器的供电系统提供足够的电力。因此,数据中心的供电系统需要设计一定的裕度。变压器112的额定功率可以高于IT设备140的平均功率,例如可以是IT设备140平均功率的1.1-1.3倍。但上述功率裕度的设定使得供电系统的利用率更低。
近年来数据中心建设规模逐年增大,数据中心的能耗占比增长迅速。特别是在中大型城市中,需要提高数据中心供电系统的利用率。通过分布冗余(distribution redundancy,DR)或N+冗余(N+redundancy,N+R)的方式,可以提高数据中心供电系统的利用率。
图2是分布冗余供电架构的示意图。
供电模块210、供电模块220、供电模块230为IT设备241、IT设备242、IT设备243供电。供电模块210包括UPS 211、变压器212、电池213,供电模块220包括UPS 221、变压器222、电池223,供电模块230包括UPS 231、变压器232、电池233。
每个IT设备的容量均为A。容量也可以称为额定功率。每个供电模块的容量相同,均为1.5A,也就是说,每个供电模块的变压器的输出功率为1.5A。变压器的输入功率与变压器的输出功率相等,可以理解为电源提供的功率。一般情况下,变压器的输出功率为固定值。
每个IT设备大致由其中两个供电模块分别供应一半的功率,约0.5A。因此,不考虑功率裕度的情况下,三母线(即三个供电模块)的DR架构功率的利用率最高为66.67%。当三个供电模块中任何一个供电模块出现故障或进行维护,不再为IT设备供电时,由另外两个供电模块提供电力,IT设备不会断电。
DR架构也可以包括四个或更多的供电模块。由M个供电模块为M-1个IT设备供电,供电系统的功率利用率为
Figure PCTCN2020111950-appb-000001
其中,M为正整数。
供电模块的数量越多,供电系统的功率利用率越高。
图3是N+冗余(redundancy,R)供电架构的示意图。在图3所示的架构中,N=2。
供电模块310为IT设备341的主供电模块,供电模块320为IT设备342的主供电。供电模块310包括UPS 311、变压器312、电池313,供电模块320包括UPS 321、变压器322、电池323。
供电模块330为IT设备341和IT设备342的备用供电模块。供电模块330包括UPS 331、变压器332、电池333。
每个IT设备的容量均为A。每个供电模块的容量相同,均为A,也就是说,每个供电模块中变压器的输出功率为A。变压器的输出功率也可以理解为电源的功率。一般情况下,变压器的输出功率为固定值。
当供电模块310和供电模块320中的一个供电模块出现故障或进行维护,不能为对应的IT设备供电时,供电模块330为该IT设备供电。
因此,三个供电模块中任何一个供电模块出现故障或进行维护,IT设备均不会断电。
2+R架构基础设施的利用率为66.67%。
N+R供电架构可以是由3个供电模块组成2+R系统,也可以由4个或更多个供电模块组成。由N个供电模块为N-1个IT设备供电,供电系统的功率利用率为
Figure PCTCN2020111950-appb-000002
其中,N为正整数。
供电模块的数量越多,供电系统的功率利用率越高。
根据图1-图3的说明,不考虑功率裕度的影响,与2N供电架构相比,DR供电架构和N+R供电架构能有效提高供电系统的功率利用率,供电系统的功率利用率可以从50%提高到66.7%或更高。
DR供电架构和N+R供电架构的功率利用率与供电模块的数量有关,供电模块的数量越多,供电架构的功率利用率越高。
但是,DR供电架构和N+R供电架构的可靠性较低。2N系统相当于1+1备份系统,假设一个供电模块的可靠度是0.9,则2N供电架构可靠度为
1-(1-0.9) 2=0.99
而由三个供电模块供电的DR供电架构或N+R供电架构的可靠度为
Figure PCTCN2020111950-appb-000003
供电架构中的供电模块越多,成本越低,但可靠度也越低。可见,DR供电架构和N+R供电架构均是以牺牲系统可靠度为代价,提高供电模块的冗余度,从而提高供电系统的功率利用率。
为了解决如何在提高电源的功率利用率的情况下,减小对数据中心中的业务的影响, 提高用户体验,本申请实施例提供了一种供电方法。

第一设备中业务的重要性高于每个第二设备的业务的重要性。第一设备与至少一个第二设备中的业务可以不同。第一设备中的业务可以是出租云业务和/或私有云业务,第二设备中的业务可以是公有云业务。也就是说,第二设备中的业务可转移。第一设备可以理解为重要设备,第二设备可以理解为次重要设备。
第二设备可以包括通信接口。第二设备中的业务可以通过有线或无线的方式转移。第二设备中的业务可以通过各种通信系统实现,例如:全球移动通信(global system for mobile communications,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、未来的第五代(5th generation,5G)系统或新无线(new radio,NR)等。
供电装置用于为数据中心中的设备供电。供电装置可以包括第一不间断电源UPS和第二UPS。第一UPS可以用于控制第一电源和第一储能装置为第一设备供电。第二UPS可以用于控制第一电源和第二储能装置为至少一个第二设备供电。其中,第一储能装置可以为第一设备补充供电,即第一电源提供的功率不能满足第一设备的功率需求时,功率不足的部分由第一储能装置为第一设备提供。第二储能装置可以为至少一个第二设备补充供电。第一电源提供的功率不能满足第一设备的功率需求,即第一设备的瞬时功率大于第一电源输入第一UPS的瞬时功率。
一般情况下,第一电源输入第一UPS的电源输入功率与第一电源输入第一UPS的电源输入功率之和可以等于第一电源的提供功率值。因当理解,等于也可以是约等于。一般情况下,电源提供的功率值固定,即电源的额定功率。在一些情况下,电源提供的功率值可能小于电源的额定功率。
在步骤S401,可以获取第一储能装置的电量。
根据第一储能装置的电量,可以确定第一电源在一段时间内为所述第一设备提供的第一电源功率是否充足。

储能装置可以是电池、飞轮或其他具有电能存储功能的设备。
当第一电源输入第一UPS的功率为额定值,第一电源输入第一UPS的功率小于第一设备的实时功率需求时,由第一储能装置进行补充,以满足第一设备的实时功率需求。当第一电源输入第一UPS的功率大于第一设备的实时功率需求时,第一电源输入第一UPS的功率除了供应给第一设备以维持其运行,还可以为第一储能装置供应,以使得第一储能装置充电。
第二UPS可以实现第二储能装置与第一电源对第一设备的联合供电。
可以由第一UPS或第二UPS确定第一电源功率不足。可以检测一段时间内第一设备的功率消耗,确定第一设备消耗的电能。可以在预设时间内第一设备消耗的电能大于预设消耗量的情况下,进行步骤S402。
也可以通过对第一储能装置的电量检测,确定第一电源功率不足。
第一UPS可以检测第一储能装置的电量。第一UPS可以确定所述第一储能装置的电量小于或等于第一预设电量,以确定所述第一电源输入第一UPS的功率不足。
在一段时间内,如果第一设备的实时功率需求较高,第一储能装置补充供电的时间较长,第一储能装置的电量下降。当第一储能装置的电量小于或等于第一预设电量时,可以进行步骤S402。
步骤S401之前,第一电源输入第一UPS的功率可以为额定值。第一电源输入第一UPS的功率不足,即第一电源输入第一UPS的功率的额定值不能满足第一设备的功率需求。第一电源输入第一UPS的功率的额定值可以大于或等于第一设备的平均功率。第一电源输入第一UPS的功率的额定值也可以成为第一设备的额定功率。
第一预设电量也可以称为备电量,可以是预设的电量值。所述第一预设电量用于指示所述第一设备中的业务运行大于或等于预设时长所需的电量。预设时长也可以称为备电时间。第一设备中的业务运行的预设时长也可以理解为第一设备运行的预设时长。
第一预设电量可以根据第一储能装置能够支持第一设备运行的备电时间t确定。一般情况下,第一储能装置的第一预设电量Q可以支持第一设备运行5-10分钟。第一设备的额定功率为Pa,则第一储能装置的第一预设电量Q=Pa×t。
在步骤S402,当所述第一储能装置的电量小于或等于第一预设电量时,降低所述第一电源输入所述第二UPS的电源输入功率。
目标第二设备是第二设备。至少一个目标第二设备可以是至少一个第二设备中的全部或部分第二设备。
可选地,第一电源输入第一UPS的功率可以是定值,第一电源输入第二UPS的功率可以是定值。当第一UPS确定第一电源输入第一UPS的功率不足,第一UPS可以向第二UPS发送电量指示信息。第二UPS接收电量指示信息后,可以开始为第一设备供电。也就是说,在步骤S402之前,第一UPS为第一设备供电,第二UPS为至少一个第二设备供电。在步骤S402之后,第一UPS和第二UPS均为第一设备供电。应当理解,第二UPS在为第一设备供电的同时,可以为至少一个第二设备供电,也可以停止为该至少一个第二设备供电。
可以由功率恒定的电源为第一UPS与第二UPS供电。这种情况下,第一电源输入第一UPS的功率与第一电源输入第二UPS的功率之和可以是定值。第一电源输入第一UPS 的功率与第一电源输入第二UPS的功率之和可以是与电源连接的变压器的输出。变压器的输出小于或等于变压器的额定功率。一般情况下,变压器的输出功率为额定功率。
在一些实施例中,在步骤S401之前,可以通过限制第一电源输入第一UPS的功率为第一设备的额定功率。从而,第一电源输入第二UPS的功率为电源的功率减去第一电源输入第一UPS的功率的限制值。
当第一UPS确定第一电源输入第一UPS的功率即第一电源输入第一UPS的功率不足,可以取消对第一电源输入第一UPS的功率的限制,或者,也可以提高输入功率的限制值,从而使得第一电源输入第一UPS的功率,即第一电源为至少一个第二设备提供的功率降低。应当理解,第二UPS可以降低第一电源为至少一个目标第二设备提供的功率。至少一个目标第二设备可以是该至少一个第二设备的部分或全部。
应当理解,第二UPS可以包括一个或多个第二UPS部分,第二储能装置可以包括一个或多个第二储能部分,第二UPS部分可以与第二储能部分一一对应。第二UPS部分可以用于控制第一电源和该第二UPS部分对应的第二储能部分为一个或多个第二设备供电。第一电源为至少一个目标第二设备提供的功率,即第一电源输入该至少一个目标第二设备对应的至少一个第二UPS部分的功率降低。目标第二设备之外的其他第二设备可以按照之前的方式供电。
取消对第一电源输入第一UPS的功率的限制之后,第一电源输入第一UPS的功率根据第一设备对功率的需求确定。当然,取消对第一电源输入第一UPS的功率的限制之后,第一电源输入第一UPS的功率也可以考虑第一设备对应的储能装置充电的需求。
在另一些实施例中,可以限制第一电源输入第二UPS的功率,第一电源输入第一UPS的功率根据第一电源输入第二UPS的功率确定,即第一电源输入第一UPS的功率等于电源的功率减去第二UPS输入功率的限制值。第二UPS输入功率的限制值可以是根据电源的功率与第一设备的额定功率确定的。
当第一UPS确定第一电源输入第一UPS的功率不足,第一UPS可以向第二UPS发送电量指示信息。第二UPS接收电量指示信息后,降低输入功率的限制值,从而使得第一电源输入第二UPS的功率降低。或者,第二UPS接收电量指示信息后,限制第二UPS输入功率为电源的功率减去第一电源输入第一UPS的功率,而第一电源输入第一UPS的功率根据第一设备对功率的需求确定。取消对第一电源输入第二UPS的功率的限制之后,第一电源输入第一UPS的功率也可以考虑第一设备对应的储能装置充电的需求。
还可以对第一UPS和第一电源输入第二UPS的功率均进行限制。当第一UPS确定第一电源输入第一UPS的功率不足,第一UPS取消第一电源输入第一UPS的功率限制,并向第二UPS发送电量指示信息。第二UPS接收电量指示信息,降低第一电源输入第二UPS的功率。
电量指示信息可以用于指示第一储能装置的电量小于第一预设电量,或指示第一电源输入第一UPS的功率不足。或者,电量指示信息可以用于指示降低第一电源输入第二UPS的功率。电量指示信息还可以用于指示至少一个目标第二设备。电量指示信息还可以用于指示降低第一电源输入第二UPS的功率的方式。
第一电源输入第一UPS的功率与第一电源输入第二UPS的功率之和是定值的方式,可以使得本申请实施例提供的数据中心供电方法与现有的供电架构兼容,从而减小在现有 的数据中心应用本申请实施例提提供的供电方法的成本。
第一电源输入第一UPS的功率与第一电源输入第二UPS的功率之和是定值的情况下,降低第一电源输入第二UPS的功率的方式有多种。可以是降低第一电源输入第二UPS的功率限制值,也可以是提高第一电源输入第一UPS的功率限制值,还可以是取消第一电源输入第一UPS的功率的限制,根据第一设备的功率需求,调整第一UPS和第一电源输入第二UPS的功率。
也就是说,可以根据所述第一设备对所述第一电源的功率需求,确定所述第一电源输入所述第二UPS的电源输入功率。
根据第一设备对电源功率的需求,对第一电源输入所述第二UPS的电源输入功率进行调整,从而满足第一设备的功率需求。
第一设备对第一电源的功率需求,可以理解为第一设备的瞬时功率需求,也可以理解为一段较短的时间,如几秒之内第一设备的平均功率。第一储能装置为第一设备补充供电,第一设备对第一电源的功率需求还可以理解为第一储能装置进行充电以及第一设备中业务运行对第一电源的总的功率需求。
取消第一电源输入第一UPS的功率的限制后,第一UPS为第一设备供电的同时,需要为第一储能装置充电。因此,第一电源输入第一UPS的功率增加。第一电源输入第一UPS的功率与第一电源输入第二UPS的功率之和可以是定值,根据第一电源输入第一UPS的功率调整第一电源输入第二UPS的功率,第一电源输入第二UPS的功率降低。
由于第二设备的业务可转移,可以防止断电使得第二设备中的业务无法运行。
当所述第二储能装置的电量小于第三预设电量时,向所述至少一个第二设备中的至少一个目标第二设备发送转移指示信息,所述转移指示信息用于指示所述至少一个目标第二设备转移业务。
UPS单元可以检测第二储能装置的电量,第二储能装置用于为所述至少一个第二设备供电。当所述第二储能装置的电量小于第三预设电量,UPS单元向所述至少一个第二设备中的至少一个目标第二设备发送转移指示信息,所述转移指示信息用于指示所述至少一个目标第二设备转移业务。
第三预设电量支持所述至少一个目标第二设备运行的时间可以大于或等于所述至少一个目标第二设备中业务的转移时间。从而,至少一个目标第二设备中的业务能够完全转移,防止断电导致的至少一个目标第二设备中的业务无法运行。
第二设备为多个时,可以根据第一储能装置中电量的消耗速率,确定目标第二设备的数量。第一储能装置中电量的消耗速率越快,目标第二设备的数量越多。可以根据经验确定第一储能装置中电量的消耗速率与目标第二设备数量的一一对应关系,并存储该一一对应关系。当第二设备为多个时,根据第一储能装置中电量的消耗速率,以及第一储能装置中电量的消耗速率与目标第二设备数量的一一对应关系,在多个第二设备中确定目标第二设备的数量。
现有技术中,为了避免第一设备在一段时间中均处于高于平均功率运行的情况下储能装置电量消耗的问题,通常在设置第一电源输入第一UPS的功率的额定值时设置一定裕度,使得第一电源输入第一UPS的功率的额定值大于第一设备的平均功率。
本申请实施例中,第一电源输入第一UPS的功率的额定值可以等于所述第一设备的 平均功率。等于也可以理解为约等于。第一电源输入第一UPS的功率的额定值不再设置裕度,而是等于所述第一设备的平均功率,可以进一步增加功率利用率。
在本申请实施例提供的方法中,第一设备在一段时间中均处于高于平均功率运行的情况下,可以通过降低电源为至少一个目标第二设备提供的电源功率的方式,提高电源为第一设备的提供的功率。因此,第一电源输入第一UPS的功率的额定值可以等于所述第一设备的平均功率,从而使得供电系统的功率利用率进一步提高。
在步骤S402之后,UPS单元可以检测第一储能装置的电量。
当所述第一储能装置的电量大于所述第二预设电量时,停止对所述第一电源输入所述第二UPS的电源输入功率的降低,所述第二预设电量大于或等于所述第一预设电量。
也就是说,当第一储能装置的电量超过第一储能装置的第二预设电量,UPS单元可以停止对第一电源输入第二UPS的功率的降低。第一储能装置的第二预设电量可以大于或等于第一储能装置的第一预设电量。
也就是说,可以在第一储能装置的电量超过第一储能装置的第二预设电量之后,限制第一电源输入第一UPS的功率为额定值。或取消第一电源输入第一UPS的功率额定值的提高。
因此,在第一储能装置的电量达到第一储能装置的第二预设电量之后,可以恢复第一电源输入第二UPS的功率。
可以在第一储能装置的电量达到第一储能装置的第二预设电量之后,恢复至少一个目标第二设备对应的输入功率。也可以在第二储能装置的电量达到第二储能装置的电量预设值之后,恢复至少一个目标第二设备对应的输入功率。第二储能装置的电量预设值可以大于第二储能装置的第三预设电量。
应当理解,第二UPS可以为多个第二设备供电。该多个第二设备均为数据中心中的设备。
当第二储能装置的电量低于第三预设电量时,UPS单元可以向多个第二设备中的全部或部分第二设备发送电量指示信息。该全部或部分第二设备即至少一个目标第二设备。接收到电量指示信息的第二设备可以进行业务转移。接收到电量指示信息的第二设备集合可以称为集合1,未接收到电量指示信息的第二设备集合可以称为集合2。
第三预设电量可以大于或等于集合1中的第二设备进行业务转移所需的电量,以及集合2中的第二设备在集合1中的第二设备进行业务转移以及集合2中的第二设备进行业务转移期间所需的电量。
也就是说,第三预设电量可以根据停止为多个第二设备供电的方式确定。第二UPS可以依次或一次性停止为多个目标第二设备供电。第二UPS可以停止为多个目标第二设备中全部或部分第二设备供电。
第二设备的电量达到第二储能装置的电量预设值,可以依次或一次性开始为该多个第二设备供电。
可以控制第二UPS与每个第二设备之间的开关,控制第二UPS开始或停止为每个第二设备供电。第二UPS与每个第二设备之间的开关可以设置在配电柜中。
应当理解,UPS单元可以检测第一电源输入第一UPS的功率是否充足,即确定第一电源输入第一UPS的功率状态。UPS单元可以根据第一电源输入第一UPS的功率状态, 调整电源为全部或部分第二设备提供的电源功率。
第一电源输入第一UPS的功率状态可以包括供电剩余,供电充足,供电不足三种状态。供电不足时,可以执行步骤S401至步骤S402。
当供电剩余时,也可以提高第一电源输入第二UPS的功率。可以检测第一储能装置的电量。当第一储能装置的电量大于剩余状态电量时,确定第一储能装置对应的输入功率状态为供电剩余。
通过本申请实施例提供的方法,数据中心的功率利用率提高。
可以将本申请实施例应用在2N供电架构、DR供电架构、N+R供电架构中。对于第一设备,供电系统的可靠性不降低。具体可以参见图5至图11的说明。

本申请实施例提供的方法可以应用在N+R供电架构中。冗余(redundancy,R)对应的供电模块包括第三UPS和第四UPS。正常情况下,第二电源输入第四UPS的功率为第二电源的额定功率。在第三UPS为第一设备供电的情况下,第三UPS可以参照第一UPS的供电方式为第一设备供电,第四UPS可以参照第二UPS的供电方式为至少一个第三设备供电。
可选地,所述数据中心还包括:至少一个第三设备,所述第一设备中业务的重要性高于每个所述第三设备中业务的重要性,每个所述第三设备中的业务可转移。

本申请实施例提供的方法可以应用在分布冗余(distribution redundancy,DR)供电架构中。
第一电源输入第一UPS的额定功率与第二电源输入第三UPS的额定功率之和,等于第一设备的额定功率。第一设备的额定功率可以大于或等于第一设备的平均功率。
图5是本申请实施例提供的一种供电系统的示意性结构图。
变压器512和变压器522的输出功率均为1。功率也可以称为容量。变压器512和变压器522的电力来源可以是市电。
市电经变压器512后,输入UPS 511a和UPS 511b。UPS 511a和UPS 511b的最大功率均为1。UPS 511a为第一设备541供电,第一设备541的额定功率为1,峰值功率可以大于1。UPS 511b为第二设备551供电。
当UPS 511a的输入功率不足时,UPS 511a的输入功率和电池513a中存储的电能联合为第一设备541提供电力,可以实现UPS 511a和电池513a的联合供电,即电池、市电联合供电。同理,当UPS 511b的输入功率不足时,电池513b和UPS 511b进行联合供电。
市电经变压器522后,输入UPS 521a和UPS 521b。UPS 521a和UPS 521b的额定功率均为1。UPS 521a为第一设备541供电,UPS 521b为第二设备551供电。当输入功率 不足时,UPS 521a和电池523a,以及UPS 521b的输入功率和电池523b,可以分别实现电池、市电联合供电。
电池513a、电池523a的备电时间均为t,备电量均为Q。备电时间t一般为5至15分钟(minute,min)。第一设备541的额定功率为Pa,Q=Pa×t。
当市电容量不足时,UPS 511a、UPS 521a可以实现市电、电池联合供电,例如市电能提供给UPS 511a、UPS 521a的功率均为0.5,当UPS 511a的负载超过0.5时,UPS 511a可以启动市电、电池联合供电模式,由市电提供0.5的能量,不足的能量由电池513a补充。
第一设备541瞬时峰值功率为Pp,Pp最大持续时间为ta。电池513a、电池523a备电量Q也可以考虑瞬时峰值功率的影响,满足重要负载的峰值功率需求。因此,备电量Q可以表示为:Q=Pa×t+Pp×ta。
考虑系统效率X的影响,备电量

第二设备551的额定功率为1,峰值功率可以大于1。第二设备中的业务可以实现快速转移,转移至第二设备552或其他第二设备(图5中未示出)中。
配电柜561和配电柜562中设置有开关。
如图5所示的各设备之间可以设置信号线,使得各个设备可以进行通信。例如,进行业务转移的两个第二设备之间存在信号线,以实现业务的转移。
图5所示的供电系统的运行原理可以参见图6至图8的说明。UPS 511a和UPS 521a均可以视为第一UPS。UPS 511b和UPS 521b均可以视为第二UPS。
本申请实施例提供的供电方法,可以保证UPS 511a和UPS 521a下游的第一设备541满足供电2N备份及备电量Q对应的备电时间要求,确保第一设备541的可靠性不低于2N架构。
UPS 511b和UPS 521b还可以为第二设备552供电。
在传统的2N结构中,设备的额定容量一般需要设定一定裕度,即设备的额定容量大于设备的平均容量。为了提高功率利用率,在图5所示的供电架构中,可以将设备的平均容量设定为设备的额定容量。因此,在变压器512和变压器522的容量不变的情况下,UPS 511b和UPS 521b还可以为第二设备552供电。
在UPS 511b为第二设备551和第二设备552供电时,预设电量Qt能够支持第二设备551和第二设备552运行的时间为时长tx。在时长tx内,第二设备551和第二设备552可以同时或依次将业务转移到其它第二设备。
UPS 511b可以停止为第二设备551和/或第二设备552供电。
配电柜561中的开关依次断开一部分或全部,即全部或部分开关脱扣,直到UPS 511b的输入功率可以匹配未断开连接的第二设备的功率需求。例如,配电柜561可以断开与第二设备551的连接,以使得UPS 511b停止为第二设备551供电,继续为第二设备552供电。
UPS 521b也可以停止为第二设备551和/或第二设备552供电。
当UPS 511b停止为所有的第二设备供电时,可以将供电功能关闭,即可以关闭用于供电的电路,以减小电力消耗。
本申请实施例提供的供电方法,在传统2N供电架构的基础上,供电模块为增加的第 二设备供电,增加的第二设备中的业务可转移。在原有的第一设备供电不足的情况下,第二设备中的业务转移,供电模块停止为第二设备供电,优先保证原有的第一设备供电。对于第一设备,本申请实施例提供的供电方法中供电模块的可靠度与传统2N供电架构中供电模块的可靠度相同,系统中的功率利用率提高。系统中的功率利用率可以提高至100%。

在步骤S801,第二UPS检测第二电池的电量。
在步骤S802,第二UPS判断第二电池的电量与预设电量Qt的大小关系。
第二UPS可以实时监测第二电池的电量。当第二电池的电量不满足预设电量Qt时,第二UPS向第二设备发送转移指示信息。转移指示信息用于第二设备开始进行业务的转移。
预设电量Qt可以由第二设备的业务转移所需要的时间决定。预设电量Qt能够支持第二设备运行的时间为时长tx。在时长tx内,第二设备业务中的业务可以安全转移到其它设备中。
在完成步骤S803且经过时长tx之后,进行步骤S804。

另外,由于供电模块310、供电模块320、供电模块330输入功率设置的最大值存在裕度,即供电模块310、供电模块320、供电模块330输入功率的最大值大于IT设备341和IT设备342的平均功率,即变压器312提供的功率大于IT设备341的平均功率,变压器322提供的功率大于IT设备342的平均功率,从而使得供电架构的功率利用率较低。
在供电模块310中增加UPS 1111和电源1113,在供电模块320中增加UPS 1121和电源1123。将UPS 311的输入功率的额定值设置为IT设备341的平均功率,变压器312提供的功率还可以通过UPS 1111为第二设备1151供电。将UPS 321的输入功率的额定值 设置为IT设备342的平均功率,变压器322提供的功率还可以通过UPS 1111为第二设备1152供电。因此,供电模块310、供电模块320、供电模块330的功率利用率可以提高至100%。
