Description

一种电源模组及整机柜
本申请要求于2019年11月1日提交中国专利局、申请号为201911060571.3、发明名称为“一种电源模组及整机柜”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电力领域，尤其涉及一种电源模组以及整机柜。
背景技术
随着云计算技术的发展，云数据中心的规模越来越大，企业对供电系统的密度、成本和能效要求也越来越高。服务器厂家开始规划整柜服务器来支持此类场景，目前主流的整柜服务器主要包括单市电进机柜和双路进机柜两种类型。
其中，单市电进机柜的可靠性相比双路进机柜要低，而双路进机柜一般为2N架构，即电源为N+N配置，如此导致机柜配置电源数量较多，成本较高，且密度低。
基于此，提供一种可靠性高，且成本低、密度高的供电方案成为亟待解决的问题。
发明内容
本申请提供了一种电源模组以及整机柜，解决了已有供电方案中无法实现可靠性、成本以及密度兼顾的问题，实现了可靠性高，且成本低、密度高的供电方案。
本申请第一方面提供了一种电源模组，该电源模组具体包括多个电源模块(Power Supply Unit，PSU)以及与该电源模块一一对应的双路静态转换开关(Static Transfer Switch，STS)，其中，每个PSU包括第一端和第二端，其中，第一端可以理解为输入端，用于和该PSU对应的双路STS连接，第二端可以理解为输出端，用于和负载连接，当双路输入中的任一路掉电时，STS可以将输入自动切换为双路输入中的另一路，为负载供电。
通过为电源模块按照1:1比例配置双路STS，当双路输入中的任一路掉电时，通过双路STS可以自动切换至另一路，并且对电源模块进行少量冗余配置，无需备份配置即可实现个别电源模块或静态转换开关故障时，也能正常供电，具有较高可靠性，而且，该方案减少了备份所需的电源模块数量，降低了成本，为整机柜部署计算节点等提供了空间，提高了整机柜密度。
在第一方面的第一种可能的实现方式中，上述电源模组可以设置为可拆卸的，具体地，电源模块还可以连接开关插槽，双路STS可以通过该开关插槽插接于电源模块。如此，在单路输入场景下，还可以将该双路STS拆除，直接利用电源模块为负载供电，提高了电源模组的兼容性。
在第一方面的第二种可能的实现方式中，上述电源模组也可以设置为一体的，具体地，双路STS可以集成于电源模块中，一方面可以减少装配操作，提高装配效率，另一方面，可以减小电源模组的体积，节省空间，而且将双路STS集成在电源模块内部可以实现对双路STS的保护。
在第一方面的第三种可能的实现方式中，为了尽量避免双路输入掉电影响，可以选择配置切换时间较小的双路STS，在实际应用时，可以选择切换时间小于PSU支持的最长掉电时间的双路STS。作为一个示例，可以选择切换时间为10毫秒的双路STS。
结合第一方面或者第一方面的第一至三种实现方式中的任一种实现方式，在第一方面的第四种实现方式中，电源模组可以兼容不同供电场景，如双路交流输入场景、交流和高压直流的混合双路输入场景或者双路高压直流输入场景。
结合第一方面或者第一方面的第一至三种实现方式中的任一种实现方式，在第一方面的第五种实现方式中，所述电源模块的数量可以设置为至少比所述负载的需求功率与单个所述电源模块的功率的比值大1。假设负载的需求功率与单个电源模块的功率的比值为N，则该电源模组中电源模块的数量至少是N+1。如此，即使有一个电源模块或者一个双路STS发生故障，也能够实现对负载正常供电。
此外，当N取值较大时，相对于不间断电源(Uninterruptible Power Supply，UPS)中N+N的备份架构，N+1等冗余架构能够较大程度减少电源模块的数量，减少幅度近50％，因此，可以大幅降低供电成本，而且也为整机柜中部署计算节点等负载节省了空间，提高了整机柜的密度。
本申请第二方面提供了一种整机柜，所述整机柜包括负载和如本申请第一方面所述的电源模组，其中，电源模组和负载设置于整机柜的柜体之中，电源模组用于基于双路输入为负载供电。
其通过将电源模组和负载集成在一个机柜中，可以实现根据用户需求灵活配置硬件平台，提高机柜空间利用率，降低成本。而且，整机柜将大部分组装工作转移到工厂预先完成，通过整机柜直接进行现场快速部署，大大提高了交付效率。
在第二方面的第一种实现方式中，负载具体可以包括服务器和交换机，如此可以将电源、交换等非计算机体系结构模块与服务器这种计算机体系结构模块集成在一个机柜，实现集中供电和散热，可以提高电源效率，降低服务器能耗水平。
在第二方面的第二种实现方式中，所述整机柜还可以包括电池，该电池具体可以用于在双路输入掉电时，为所述负载供电，提高供电可靠性。
结合第二方面、第二方面的第一种实现方式或者第二种实现方式，在第二方面的第三种实现方式中，电源模组和负载可以通过各自对应的端子连接至整机柜的柜体，如此，可以方便拆卸，当个别电源模组或负载发生故障时方便维修或更换。

具体实施方式
随着云计算技术的发展，互联网对数据的需求呈现爆炸式增长，这极大地促进了云数据中心的市场需求。所谓云数据中心是一种协作的设备网络，用于在网络基础设施上传递、加 速、展示、计算、存储数据信息，为了避免影响用户体验，需要针对云数据中心提供一种可靠性较高的供电方案。
开放计算项目(Open Compute Project，OCP)提供了一种单市电进机柜部署云数据中心，虽然在一定程度上减小了能耗，但是可靠性难以保障。基于此，开放数据中心委员会(Open Data Center Committee，ODCC)提出了一种双路进机柜，通过N+N的电源架构可以实现在一路电源掉电时，通过备用的另一路电源进行供电。但是这种N+N的电源架构一方面增加了初期设备投资成本，另一方面也增加了运营时的能耗成本，而且供电密度也较低。
基于此，本申请实施例提供了一种电源模组，通过在每个电源模块前端增加一双路STS，电源模块的另一端用于连接负载，如此，当双路输入中的任一路掉电时，可以将输入自动切换为双路输入中的另一路，电源模块基于该另一路为负载供电，避免掉电影响负载正常运行，提高了供电可靠性。
而且，在该方案中每个电源模块通过对应的双路STS连接双路输入，而不是通过两个电源模块分别连接双路输入中的一路，因此，无需采用N+N架构配置备份电源模块，仅配置少量的冗余电源模块即可实现在个别电源模块或双路STS故障时也能正常供电，进一步提高了供电可靠性，而且大幅减少了需要配置的电源模块的数量，降低了成本，节省了机柜空间，如此可以提高供电密度。
下面结合附图，对本申请的实施例进行描述。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
参见图1所示的电源模组的平面结构示意图，该电源模组10包括多个电源模块11和与电源模块一一对应的双路静态转换开关12，其中，每个电源模块11包括第一端111和第二端112，所述第一端111用于连接对应的所述双路静态转换开关12，所述第二端112用于连接负载20，以为负载20供电。其中，负载20可以是任意需要供电的设备，例如计算设备如服务器，交换设备如交换机路由器等。
双路静态转换开关12输入为双路，具体可以是双路市电，如图1所示，双路市电可以表示为市电A和市电B，双路静态转换开关12可以在双路市电中的任一路掉电时，将输入自动切换为另一路，避免负载20受到掉电影响。
在具体实现时，双路静态转换开关12可以设置其中一路例如市电A为默认市电，电源模块11一般可以基于该默认市电为负载20供电，当默认市电发生掉电时，双路静态转换开关12立即将输入切换为市电B。当然，在有些情况下，默认市电如市电A恢复供电时，双路静态转换开关12也可以将输入切回至默认市电即市电A。
需要说明的是，上述“双路”并不限于两路，在实际应用时，“双路”也可以是从两路源中引出的多路输入，例如从两组发电机组中引出的四路输入等等。
在实际应用时，上述电源模组10可以设置为可拆卸的，具体地，电源模块还可以连接开关插槽，双路STS可以通过该开关插槽插接于电源模块。当然，电源模块11和双路静态转换 开关12也可以通过板卡进行连接，通过在板卡上进行插拔实现电源模组10的拆装。
参见图2所示的电源模组的三维结构图，如图2所示，电源模组10是装配于板卡13之上的，该板卡13具体可以是印刷电路板(Printed Circuit Board，PCB)，该PCB板在垂直方向上导通，将电源模块11以及该电源模块对应的双路静态转换开关12的引脚插入垂直方向的一条线上，可以实现电源模块11和双路静态转换开关12的连接。
进一步地，还可以在PCB板的相应位置，具体可以为电源模块11及其双路静态转换开关12所在直线上的位置，插上相应的引线端子14，使得引线端子14与双路静态转换开关12连接，如此可以将双路市电通过该引线端子14输入至双路静态转换开关12。
如此电源模组能够实现可拆卸，在单路市电输入场景下，还可以将该双路静态转换开关拆除，直接利用电源模块为负载供电，提高了电源模组的兼容性。
考虑到机柜中配置的电源模式数量较多的情况下，为了减少装配工作，节省部署时间，还可以在双路静态转换开关出厂前即将该双路静态转换开关集成于电源模块中。一方面可以减少装配时间，提高交付效率，另一方面将双路静态转换开关进行集成可以减少整个电源模组的体积，节省空间。并且，通过封装的方式进行集成可以实现对该双路静态转换开关的保护。
需要说明，双路静态转换开关进行市电输入切换需要一定时间，为了尽可能减小掉电对负载的影响，可以选择配置切换时间较小的双路静态转换开关，具体为切换时间小于电源模块支持的最大掉电时间的双路静态转换开关，如此，在进行切换时，可以由电源模块自身储存的电能先进行供电。在切换成功后，可以由切换后的市电输入进行供电。
为了便于理解，下面结合双路静态转换开关的电路图对切换过程进行详细说明。
参见图3所示的双路静态转换开关的电路图，该双路静态转换开关包括两条火线即L1和L2以及两条零线即N1和N2，两条火线L1和L2连接，并在连接位置还连接电流互感器组件(Current Transformer Assembly，CTA)，具体为连接CTA1，两条零线N1和N2连接，每条火线或每条零线连接有继电器(Relay，RLA)、电流互感器CTA以及可控硅整流器组件(Silicon Controlled Rectifier Assembly，SCRA)，具体地，针对L1，其连接有RLA1、CTA2、RLA5以及SCRA1、SCRA2，其中，SCRA1、SCRA2与RLA5并联，然后整体与RLA1、CTA2串联，针对N2，其连接有RLA2、SCRA3、SCRA4以及RLA6，其中，SCRA3、SCRA4与RLA6并联，然后整体与RLA2串联，L2、N2在RLA、CTA以及SCRA的连接关系与L1、N1相同，在此不再赘述。
在实际应用时，RLA1至RLA4的状态分别与L1、N1、L2、N2中是否有电相关联。当L1、N1、L2、N2有电时，默认L1给负载供电，此时，RLA1、RLA2、RLA3、RLA4闭合，此外，RLA5、RLA6闭合，RLA7、RLA8断开。当L1、N1掉电，RLA1、RLA2、RLA5、RLA6断开，RLA7、RLA8闭合，供电从L1切换到L2。
另外，考虑到切换时间，在进行切换时，SCRA先导通，由于SCRA无法长时间通流，与之并联的RLA随后闭合以旁路SCRA，实现双输入快速切换。在有些情况下，切换时间可以控制在10毫秒以内。
在该切换过程中，由电源模块中预先储存电荷的电容等器件对负载供电，图3中未示出，实现了不间断供电，具有较高可靠性。
在上述实施例中，双路输入可以是双路交流(Alternating Current，AC)输入，即AC+AC；也可以是双路高压直流(High Voltage Direct Current，HVDC)输入，即HVDC+HVDC；或者是交流和高压直流的混合双路输入，即HVDC+AC。
可见，该方法通过一种架构，实现兼容云数据中心各种输入制式，具有较好的兼容性，当输入制式发生变化时，能够自适应供电，避免了对数据中心供电架构进行改造导致的人力成本、时间成本以及材料成本等。
可以理解，电源模块的数量是根据负载需求进行配置的。考虑到需要对电源模块进行冗余设置，因此，在一些可能的实现方式中，电源模块的数量至少比负载的需求功率与单个电源模块的功率的比值大1，为了方便表述，可以将负载需求功率与单个电源模块的功率的比值记作N，也即电源模块的数量至少是N+1。作为一个示例，可以在电源模组中配置N+1个电源模块。
与传统的N+N架构相比，该方案可以大幅减少需要配置的电源模块的数量，从N+N演进到N+1,电源模块数量减少近50％，如此，大幅降低了供电成本，而且电源模块数量减少也为机柜中其他设备预留了较多空间，如此，可以提高供电密度。
当然，由于电源模块数量比正常需求多一个，因此，当电源模组中存在一个电源模块或者一个双路静态转换开关发生故障时，也能够通过剩余的电源模块进行供电，进一步提高了可靠性。并且为更换或维修故障电源模块等提供了充足的时间。
需要说明，图1、图2是以需求功率为9千瓦(kilowatt,KW)进行示例说明的，在该示例中，每个电源模块的功率为3KW，传统的供电方案采用3+3个电源模块进行供电，而本申请的方案可以采用3+1个电源模块进行供电。
在本申请其他可能的实现方式中，当需求功率以及电源模块的功率发生变化时，电源模块的数量也可以相应地发生变化，并不限于图1、图2中所示的4个。
由上可知，本申请实施例提供了一种电源模组，其通过为电源模块按照1:1比例配置双路STS，当双路市电输入中的任一路掉电时，通过双路STS可以自动切换至另一路，并且对电源模块进行少量冗余配置，无需备份配置即可实现个别电源模块或静态转换开关故障时，也能正常供电，具有较高可靠性，而且，该方案减少了备份所需的电源模块数量，降低了成本，为整机柜部署计算节点等提供了空间，提高了整机柜密度。
基于本申请实施例提供的上述电源模组，本申请实施例还提供了一种整机柜设备。下面结合附图对该整机柜设备进行详细说明。
参见图4所示的整机柜的结构示意图，整机柜40包括如上所述的电源模组41和负载42，其中，电源模组41和负载42设置于整机柜40的柜体43之中，在具体实现时，可以将电源模组41设置在柜体43的底部，将负载42设置于电源模组41之上，电源模组41基于双路市电输入为负载42供电。
在一个示例中，整机柜高度可以为2000毫米(millimeter，mm)，即39OU，其中，OU是通用机柜高度单位，1OU约等于44mm，其中3OU空间可以用于放置电源框，该电源框可以参见图5，其可以由如图2所示的电源模组堆叠形成，该整机柜中剩余空间可以用于放置负载。
该方案通过将电源模组和负载集成在一个机柜中，可以实现根据用户需求灵活配置硬件平台，提高机柜空间利用率，降低成本。而且，整机柜将大部分组装工作转移到工厂预先完成，通过整机柜直接进行现场快速部署，大大提高了交付效率。
在图4所示实施例中，负载具体可以是服务器和交换机，例如可以放置32OU服务器以及4OU交换机，通过将电源、交换等非计算机体系结构模块与服务器这种计算机体系结构模块集成在一个机柜，实现集中供电和散热，可以提高电源效率，降低服务器能耗水平。
进一步地，在实际应用时，整机柜40中还可以包括电池，例如可以从32OU服务器中取出3OU用于放置电池，如此，在双路市电输入均掉电时，还可以通过电池为服务器、交换机等负载进行供电，提高供电可靠性。
考虑到维护需求，电源模组41和负载42可以通过各自对应的端子如电源端子、负载端子连接至整机柜40的柜体43，如此，可以方便拆卸，当个别电源模组41或负载42发生故障时方便维修或更换。
由上可知，本申请实施例提供了一种整机柜，其将电源模组、负载集成在一个机柜中，电源模组中的每个电源模块配置有对应的双路静态转换开关，该双路静态转换开关可以接收双路市电输入，并在双路市电输入中的任一路掉电时切换至另一路，避免掉电影响负载正常运行。此外，每个电源模块均接收双路市电输入，而不是通过两个电源模块分别连接双路市电输入中的一路，因此，无需将电源模块完全备份，只需在正常需求数量上额外配置少量电源模块，使得个别电源模块故障时，也能正常供电，提高可靠性，而且减少了需要配置的电源模块的数量，降低了成本，并为整机柜中配置计算节点等预留了空间，提高了供电密度。
另外需说明的是，以上所描述的实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。另外，本申请提供的装置实施例附图中，模块之间的连接关系表示它们之间具有通信连接，具体可以实现为一条或多条通信总线或信号线。
通过以上的实施方式的描述，所属领域的技术人员可以清楚地了解到本申请可借助软件加必需的通用硬件的方式来实现，当然也可以通过专用硬件包括专用集成电路、专用CPU、专用存储器、专用元器件等来实现。一般情况下，凡由计算机程序完成的功能都可以很容易地用相应的硬件来实现，而且，用来实现同一功能的具体硬件结构也可以是多种多样的，例如模拟电路、数字电路或专用电路等。
但是，对本申请而言更多情况下软件程序实现是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在可读取的存储介质中，如计算机的软盘、U盘、移动硬盘、ROM、RAM、磁碟或者光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，训练设备，或者网络设备等)执行本申请各个实施例所述的方法。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。
