Description

数据中心供配电系统 技术领域
本申请涉及电力电子技术领域，具体涉及数据中心供配电系统。
背景技术
数据中心可以理解成对各种电子设备提供集中处理、存储、传输、交换、管理等功能和服务的物理空间。部署在数据中心的电子设备多为精密的IT设备，例如计算机、服务器、网络设备、存储设备等。这些IT设备有较高的供电质量要求，要求数据中心提供连续、稳定、平衡且安全的供电环境。然而，市电电网等电源存在闪断、波动、瞬变等问题，因此市电电网等电源不适合直接提供给IT设备，而需要先经过数据中心供配电系统的处理才能配电给IT设备。
现有技术中，有一种数据中心供配电系统利用不间断电源(Uninterruptible Power Supply，UPS)。基于UPS的数据中心供配电系统将市电经过中压配电柜配电到集中式供电的UPS供电系统，再经过工频变压器降压然后经过低压配电柜配电到UPS电源，UPS电源将降压后的市电整流成直流电后与储能电池提供的直流电一起再逆变成交流电380Vac，最后通过UPS输出配电柜配电给IT设备。基于UPS的数据中心供配电系统至少需要中压配电柜、工频变压器、低压配电柜、UPS整流环节和逆变环节以及UPS输出配电柜，因此有设备多环节复杂占地空间大的缺点；另外必须利用集中式供电方式将市电经过工频变压器降压，且供电设备布置在IT负载所在区域之外，从而要求较长的低压母线来实现对IT设备的配电，因此有线路损耗大成本高的缺点。在IEC 60038中定义1kV至35kV电力系统的电压标准为中压。低于1KV的为低压。一般业界以该标准区分中压或者低压，实践中当然可以略有浮动。以常见的功率为2MW的UPS供电方案为例，假设额定电流为3030A，则需要利用3150A的低压母线，成本高达数千元每米，且每米损耗可达78W。另一种数据中心供配电系统利用高压直流输电(High Voltage Direct Current Transmission，HVDC)。基于HVDC的数据中心供配电系统将市电经过工频变压器降压最后与储能电池提供的直流电一起输出直流电240Vdc或者360Vdc。基于HVDC的数据中心供配电系统具有与基于UPS的数据中心供配电系统类似的布局，也有设备多、环节复杂、占地空间大以及低压母线过长、线路损耗大、成本高的缺点。
现有技术中，还有一种数据中心供配电系统利用符合开放计算项目(Open Compute Project，OCP)规范的机架供电系统和电源技术。现有的OCP电源的数据中心供配电系统，将经过中压配电柜配电到集中放置的工频变压器和低压配电柜，经过工频变压器降压然后经过低压配电柜配电到分布式放置在各个IT机柜内的OCP电源和储能电池。基于OCP电源的数据中心供配电系统需要集中放置工频变压器和低压配电柜，而供电设备布置在各个IT机柜所在区域之外，从而要求较长的低压母线来实现对各个IT机柜的配电，因此有线路损耗大成本高的缺点；另外OCP电源和储能电池必须放置在各个IT机柜之内，从而占用了IT设备的空间，不利于减少数据中心供配电系统的整体占地空间。
为此，需要一种技术方案既能满足数据中心的IT设备所要求的连续、稳定、平衡且安全的供电环境，又能解决现有技术中的数据中心供配电系统存在的设备多、环节复杂、占地空间大以及低压母线过长、线路损耗大、成本高的缺点。

本申请实施例可用于以下应用场景：大中小型数据中心、研究站、科学站或者其它需要对各种电子设备进行集中处理和管理的场景。
本申请实施例可以依据具体应用环境进行调整和改进，此处不做具体限定。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请的实施例进行描述。
请参阅图1，图1示出了本申请实施例提供的第一种实施方式的SST供电系统的结构框图。如图1所示，SST供电系统100包括整流模块120、逆变模块130和储能装置140。其中，整流模块120接收市电交流电1000V ac，将市电交流电1000Vac整流成直流电400Vdc，再与储能装置140输出的直流电一起输送给逆变模块130，最后由逆变模块130再逆变成交流电220Vac后输出给适用交流输入电源的IT负载。整流模块120还包括AC/DC变换器121用于将整流模块120所接收的市电交流电转换成低压直流电，以及DC/DC变换器122用于将AC/DC变换器121输出的低压直流电转换成直流电400Vdc。整流模块120输出的直流电400Vdc接上逆变模块130的输入。储能装置140的直流输出也接在逆变模块130的输入上，用于稳定整流模块120的输出，从而使得逆变模块130的输入有稳定的直流电压，实现该SST供电系统100不间断供电。应当理解的是，SST供电系统100利用的是固态变压器(Solid State Transformer，SST)，也叫做电力电子变压器(Power Electronic Transformer，PET)或者电子电力变压器(Electronic Power Transformer，EPT)，因此利用了高频变压器而没有利用工频变压器，从而大幅减小了变压器的体积和重量。也就是说，SST供电系统100通过利用SST实现从市电交流电1000Vac到输出的交流电220Vac的降压过程，从而无需用到工频变压器进行降压，也因此不需要集中放置工频变压器和对应的低压配电柜，从而可以将SST供电系统100部署在IT设备附近，有利于减少占地空间、减少低压母线的长度、降低损耗和减少成本。另一方面，SST供电系统100无需通过工频变压器对市电交流电进行降压，而是直接将市电交流电1000Vac转换成直流电400Vdc之后与储能装置140的直流输出一起作为逆变模块130的输入，从而减少了所需设备和简化了环节。应当理解的是，图1所示的SST供电系统100的输出的交流电220Vac仅为示例性，在一些示例性实施例中，也可以输出其它规格的交流电例如输出400Vac。储能装置140可以是锂电池、锂电模块或者其它类型的储能装置，还可以利用多个锂电模块的并联形式来提供直流补偿电源从而实现稳定的直流电压。在一些示例性实施例中，SST供电系统100还包括机柜单元(未示出)用于放置SST供电系统100的各个组件，该机柜单元也可以独立于SST供电系统100而分开布置。
请参阅图2，图2示出了本申请实施例提供的第二种实施方式的SST供电系统的结构框图。如图2所示，SST供电系统200包括整流模块220和储能装置240。其中，整流模块220接收市电交流电1000Vac，将市电交流电1000Vac整流成直流电400Vdc，再与储能装置240输出的直流电一起输出给适用直流输入电源的IT负载。整流模块220还包括AC/DC变换器221用于将整流模块220所接收的市电交流电转换成低压直流电，以及DC/DC变换器222用于将AC/DC变换器221输出的低压直流电转换成直流电400Vdc。整流模块220输出的直流电400Vdc直接输出给IT负载。储能装置240的直流输出也接在SST供电系统200的输出上，用于稳定整流模块220的输出，从而使得SST供电系统200的输出有稳定的直流电压，实现该SST供电系统200不间断供电。应当理解的是，SST供电系统200利用的是固态变压器SST，也叫做电力电子变压器PET或者电子电力变压器EPT，因此利用了高频变压器而没有利用工频变压器，从而大幅减小了变压器的体积和重量。也就是说，SST供电系统200通过利用SST实现从市电交流电1000Vac到输出的直流电400Vdc的降压过程，从而无需用到工频变压器进行降压，也因此不需要集中放置工频变压器和对应的低压配电 柜，从而可以将SST供电系统200部署在IT设备附近，有利于减少占地空间、减少低压母线的长度、降低损耗和减少成本。另一方面，SST供电系统200无需通过工频变压器对市电交流电进行降压，而是直接将市电交流电1000Vac转换成直流电400Vdc之后与储能装置140的直流输出一起作为SST供电系统200的输出，从而减少了所需设备和简化了环节。应当理解的是，图2所示的SST供电系统200的输出的直流电400Vdc仅为示例性，在一些示例性实施例中，也可以输出其它规格的直流电例如输出240Vdc。储能装置240可以是锂电池、锂电模块或者其它类型的储能装置，还可以利用多个锂电模块的并联形式来提供直流补偿电源从而实现稳定的直流电压。在一些示例性实施例中，SST供电系统200还包括机柜单元(未示出)用于放置SST供电系统200的各个组件，该机柜单元也可以独立于SST供电系统200而分开布置。
请参阅图3，图3示出了本申请实施例提供的第三种实施方式的SST供电系统的结构框图。如图3所示，SST供电系统300包括整流模块320、逆变模块330、储能装置340和旁路装置350。其中，整流模块320接收市电交流电1000Vac，将市电交流电1000Vac整流成直流电400Vdc，再与储能装置340输出的直流电一起输送给逆变模块330，最后由逆变模块330再逆变成交流电220Vac后输出给适用交流输入电源的IT负载。旁路装置350与逆变模块330并联连接于整流模块320的输出和SST供电系统300的输出之间。旁路装置350被配置成可以对逆变模块330进行旁路处理，从而使得整流模块320输出的直流电400Vdc和储能装置340输出的直流电一起旁路逆变模块330，然后直接作为SST供电系统300的输出的直流电。如此，通过旁路装置350的操作，可以实现经过逆变模块330输出的交流电220Vac和不经过也即旁路化逆变模块330后输出的直流电400Vdc之间的切换。整流模块320还包括AC/DC变换器321用于将整流模块320所接收的市电交流电转换成低压直流电，以及DC/DC变换器322用于将AC/DC变换器321输出的低压直流电转换成直流电400Vdc。整流模块320输出的直流电400Vdc接上逆变模块330的输入或者经过旁路装置350的操作直接接上SST供电系统300的输出。储能装置340的直流输出也接在逆变模块330的输入上或者经过旁路装置350的操作直接接上SST供电系统300的输出，用于稳定整流模块320的输出，从而使得逆变模块330的输入或者SST供电系统300的输出有稳定的直流电压，实现该SST供电系统300不间断供电。应当理解的是，SST供电系统300利用的是固态变压器SST，也叫做电力电子变压器PET或者电子电力变压器EPT，因此利用了高频变压器而没有利用工频变压器，从而大幅减小了变压器的体积和重量。也就是说，SST供电系统300通过利用SST实现从市电交流电1000Vac到输出的交流电220Vac或者直流电400Vdc的降压过程，从而无需用到工频变压器进行降压，也因此不需要集中放置工频变压器和对应的低压配电柜，从而可以将SST供电系统300部署在IT设备附近，有利于减少占地空间、减少低压母线的长度、降低损耗和减少成本。另一方面，SST供电系统300无需通过工频变压器对市电交流电进行降压，而是直接将市电交流电1000Vac转换成直流电400Vdc之后与储能装置340的直流输出一起作为逆变模块330的输入或者SST供电系统300的输出，从而减少了所需设备和简化了环节。另外，通过旁路装置350可以使得SST供电系统300输出交流电或者直流电，有利于根据实际需求进行灵活配置。应当理解的是，图3所示的SST供电系统300的输出的交流电220Vac或者直流电400Vdc仅为示例性，在 一些示例性实施例中，也可以输出其它规格的交流电例如输出400Vac或者其它规格的直流电例如240Vdc。储能装置340可以是锂电池、锂电模块或者其它类型的储能装置，还可以利用多个锂电模块的并联形式来提供直流补偿电源从而实现稳定的直流电压。在一些示例性实施例中，SST供电系统300还包括机柜单元(未示出)用于放置SST供电系统300的各个组件，该机柜单元也可以独立于SST供电系统300而分开布置。

请继续参阅图4，通过各个区域的SST供电系统对所配电的市电进行降压，无需用到工频变压器进行降压，也因此不需要集中放置工频变压器和对应的低压配电柜，从而可以将各个SST供电系统部署在对应的IT负载附近也就是部署在同一个区域中，有利于减少占地空间、减少低压母线的长度、降低损耗和减少成本。另一方面，各个SST供电系统无需通过工频变压器对市电交流电进行降压，而是直接将市电交流电转换成直流电之后与储能装置的直流输出一起作为逆变模块的输入或者SST供电系统的输出，从而减少了所需设备和简化了环节。另外，通过各个区域的中压开关柜实现了独立操作各个区域的IT负载的配电，有利于智能电能配电。另外，通过各个区域的隔离装置实现了各个区域的配电区跟IT区之间的隔离，提高了安全性。

图9所示的数据中心供配电系统的IT负载的第二种组合可以对应图4至图7中的任一种IT负载的组合。应当理解的是，通过利用各个区域的SST供电系统对所配电的市电进行降压，因此无需用到工频变压器进行降压，也不需要集中放置工频变压器和对应的低压配电柜，从而可以将各个SST供电系统部署在各个SST供电系统所在区域的IT负载附近也就是部署在同一个区域中，从而有利于减少占地空间、减少低压母线的长度、降低损耗和减少成本。另外，因为每个区域的SST供电系统通过各自对应的中压开关柜直接从市电配电获得电能，因此每个区域的SST供电系统可以针对各自对应的IT负载情况进行不同的设计，从而有利于灵活配置应对不同区域的需求。例如，第一区域920的SST供电系统922可以设计成输出220Vac的交流电，而第一区域的IT负载被配置成适用于接收交流电输入；第二区域930的SST供电系统932可以设计成输出400Vdc，而第二区域的IT负载被配置成适用于接收直流电输入。如此，可以针对第一区域920的需求将市电转换成交流电同时针对第二区域930的需求将市电转换成直流电，相比于集中式供电配电的方式，在供电配置上有更大的灵活性。另外，如果利用图3所示的SST系统的结构，可以选择性的切换SST供电系统输出的为交流电或者直流电，有利于根据实际需求进行灵活配置。
