Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
A schematic diagram of a power supply architecture for a data center in the related art is described below with reference to fig. 1.
As shown in fig. 1, the power architecture includes a dc power supply link and an ac power supply link. The Direct-Current power supply link comprises a High-Voltage power distribution system, a transformer, a low-Voltage power distribution system, High Voltage Direct Current (HVDC) equipment and a Direct-Current column head cabinet which are sequentially and electrically connected, and the alternating-Current power supply link comprises a High-Voltage power distribution system, a low-Voltage power distribution system, a transformer and an alternating-Current column head cabinet which are sequentially and electrically connected.
In the direct-current power supply link, a high-voltage power distribution system is used for inputting a three-phase alternating-current power supply with the voltage value of 10kV, a transformer transforms the alternating-current power supply with the voltage value of 10kV into alternating current with the voltage value of 400V, the alternating current with the voltage value of 400V is sequentially transmitted to a low-voltage power distribution system and HVDC equipment, the alternating current with the voltage value of 400V is converted into direct current with the voltage value of 240V and is transmitted to a direct-current column head cabinet, and the direct current column head cabinet distributes the direct current with the voltage value of 240V to a cabinet load, so that electric energy distribution of the direct.
In the alternating current power supply link, the high-voltage power distribution system is used for inputting a three-phase alternating current power supply with the voltage value of 10kV, and the transformer transforms the three-phase alternating current power supply with the voltage value of 10kV into alternating current with the voltage value of 400V and transmits the alternating current to the low-voltage power distribution system. The low-voltage distribution system transmits 400V alternating current to the alternating current column head cabinet, then the alternating current column head cabinet converts the 400V three-phase alternating current into 220V unidirectional alternating current, and distributes the unidirectional alternating current to the cabinet load, so that the electric energy distribution of the alternating current power supply link is realized.
With the gradual failure of moore's law in recent years, in the case of the cabinet power of the data center increasing rapidly, the cabinets with the current capacity of 80A or even 120A are becoming popular. Under the power supply framework, a cabinet load with the current capacity of 40A is generally adopted, and other components such as electrical connectors, switches and the like with the current capacity of 60A-80A are generally adopted on a direct current power supply link or an alternating current power supply link. If the power supply architecture is used for supplying power to the 80A or 120A cabinet, other components such as electrical connectors and switches with the upload flow rate of 60A-80A on the dc power supply link or the ac power supply link need to be replaced by other components such as electrical connectors and switches with the larger current-carrying capacity, which increases the equipment cost of the components. Or, the power supply architecture can also increase the number of power supply links to increase the power supply power on the basis of the original two power supply links (i.e., the dc power supply link and the ac power supply link) to supply power to the load of the high-power cabinet.
Therefore, in the power supply architecture for the data center in the related art, when the data center adopts a higher-power cabinet, the technical problems of low power supply efficiency, high construction difficulty, high construction cost, high equipment cost and the like exist.
A power supply system 1 according to an embodiment of the present disclosure is described below with reference to fig. 2 and 3.
Fig. 2 shows a schematic diagram of a power supply system 1 according to an embodiment of the present disclosure. As shown in fig. 2, the power supply system 1 includes a high voltage dc conversion module 10, a low voltage conversion module 20, and a power distribution module 30.
Specifically, the high-voltage dc conversion module 10 is configured to convert a high-voltage ac input by the high-voltage power distribution system into a high-voltage dc, where a voltage value of the high-voltage dc is greater than 400V. The low voltage conversion module 20 is electrically connected to the output end of the high voltage dc conversion module 10, and is configured to convert the high voltage dc output by the high voltage dc conversion module 10 into low voltage dc. The power distribution module 30 is electrically connected to the output of the low voltage conversion module 20 for supplying power to the load device 40.
Illustratively, the HVDC conversion module 10 may employ a rectifier transformer device. More specifically, the rectification transformation device may adopt a phase-shifting transformer, and a three-phase alternating current with a voltage value of 10kV is input through a primary side, and after being stepped down and rectified, a high-voltage direct current with a voltage value of more than 400V is output through a secondary side. It should be understood that the foregoing is only illustrative, and should not be construed as a limitation to the embodiments of the present disclosure, and the high voltage dc conversion module 10 in the embodiments of the present disclosure may also adopt other voltage transformation devices, for example, a power electronic transformer, as long as it can convert a three-phase ac with a voltage value of 10kV into a high voltage dc with a voltage value of more than 400V.
The voltage value of the high voltage direct current output by the high voltage direct current conversion module 10 may be any standard direct current voltage level greater than 400V and less than 10kV, for example, 750V or 1000V.
It should be noted that the voltage value of the high-voltage direct current output by the high-voltage direct current conversion module 10 may be set correspondingly according to the power supply power requirement of the data center cabinet load. For example, when the power supply power of the data center rack load is high, the power supply power of the power supply system 1 is also increased correspondingly, and the voltage value of the high-voltage direct current output by the high-voltage direct current conversion module 10 may be increased correspondingly, so that the current value flowing through the power supply branch circuit is maintained at 60-80A, and thus other components such as a switch or a connector on the power supply branch circuit are still applicable to the current power supply branch circuit. Therefore, under the condition that the power supply power requirement of the data center cabinet load is increased, the power supply system 1 of the embodiment of the disclosure does not need to replace components such as a switch or a connector with larger current-carrying capacity, so that the cost of upgrading equipment can be saved.
Compared with a power supply framework in the related art, the high-voltage distribution equipment is used for converting an alternating-current power supply with the voltage value of 10kV into three-phase alternating current with the voltage value of 400V and transmitting the three-phase alternating current to the high-voltage direct-current equipment. In the embodiment of the present disclosure, by using the high-voltage dc conversion module 10, the three-phase ac with a voltage value of 10kV is converted into the high-voltage dc with a voltage value greater than 400V, and is transmitted to the low-voltage conversion module 20, and in a process of transmitting the high-voltage dc to the low-voltage conversion module 20, a current value of the high-voltage dc is correspondingly reduced, especially under a condition that a power supply power of the power supply system 1 is increased, a heat loss of the high-voltage dc in a process of transmitting the high-voltage dc to the low-voltage conversion module 20 can be reduced, so that a loss of.
The low-voltage conversion module 20 is configured to convert the high-voltage direct current output by the high-voltage direct current conversion module 10 into low-voltage direct current or low-voltage alternating current. It is understood that the voltage value of the low voltage output after the conversion by the low voltage conversion module 20 is lower than that of the high voltage direct current, in other words, the low voltage conversion module 20 may adopt a buck converter.
Illustratively, the low voltage conversion module 20 may employ a buck DC/DC converter, or a buck DC/AC converter, which may be selected according to the power supply requirement of the load device 40.
Accordingly, the power distribution module 30 may adopt a dc power distribution module or an ac power distribution module according to the type of the low voltage power outputted from the low voltage conversion module 20. For example, in the case that the low voltage output by the low voltage conversion module 20 is low voltage direct current, the power distribution module 30 may adopt a direct current power distribution module. For another example, when the low voltage output by the low voltage conversion module 20 is a low voltage ac power, the power distribution module 30 may adopt an ac power distribution module.
Illustratively, the dc power distribution module may employ a dc column header cabinet to distribute low voltage dc power to the load devices 40. The ac power distribution module may employ an ac column head cabinet to distribute low voltage ac power to the load devices 40.
According to the power supply system 1 of the embodiment of the present disclosure, by providing the high voltage dc conversion module 10, the three-phase ac power source with the voltage value of 10kV input by the high voltage distribution system is converted into the high voltage dc with the voltage value greater than 400V, and is transmitted to the low voltage conversion module 20, and during the transmission process of the high voltage dc, the current value of the high voltage dc can be reduced, so as to reduce the heat loss of the high voltage dc during the transmission process, thereby improving the power supply efficiency of the power supply system 1. Therefore, the technical problem that the power supply efficiency of the power supply structure in the related art is low under the condition that the power supply power requirement of the cabinet load of the data center is increased is solved. Moreover, the current value of the high-voltage direct current in the transmission process is correspondingly reduced, and can be maintained between 60A and 80A, for example, so that when the power supply power requirement of the data center cabinet load is increased, other devices such as a conventional switch or a connector with the current capacity of 60 to 80A adopted by the low-voltage conversion module 20 can still be adapted, and therefore, the switch or the connector with the larger current capacity does not need to be replaced, and the upgrading cost of the devices is saved.
Therefore, the power supply system 1 of the embodiment of the present disclosure has higher power supply efficiency in the case where the demand of the power supply power of the data center load device 40 increases, and can save the device cost.
In one embodiment, the high voltage direct current has a voltage value greater than 400V and less than or equal to 1000V. The low voltage is low voltage direct current, and the voltage value of the low voltage direct current is 240V; alternatively, the low voltage is a low voltage alternating current, and the voltage value of the low voltage alternating current is 220V.
It is understood that the voltage value of the ac supply in the domestic electric system is typically 220V, and the voltage value of the dc supply used in the field of communications is typically 240V. The voltage value of the low-voltage direct current is set to 240V, or the voltage value of the high-voltage alternating current is set to 220V, so that the power consumption requirement of most cabinet loads can be met, and the power supply range of the power supply system 1 is widened.
Preferably, the high voltage direct current has a voltage value of 750V.
On the basis, on one hand, the current of the high-voltage direct current is ensured to be smaller in the process of conveying the high-voltage direct current to the low-voltage conversion module 20, so that the heat loss in the conveying process is reduced, and the power supply efficiency is ensured; on the other hand, the voltage value of the high-voltage direct current is set to 750V, the power supply requirement of a cabinet load with the power specification of 24kW (80A) or 36KW (120A) can be met, and the current value of the high-voltage direct current in the conveying process meets the adaptation specification of other components 60-80A such as a conventional switch or a connector, so that the components do not need to be upgraded.
In one embodiment, as shown in fig. 1, the hvdc conversion module 10 includes a first hvdc conversion sub-module 11 for converting high voltage ac power input from the high voltage power distribution system into high voltage dc power. The low-voltage conversion module 20 comprises a low-voltage direct-current conversion submodule 21, which is electrically connected with the output end of the first high-voltage direct-current converter module 11 and is used for converting the high-voltage direct current output by the first high-voltage direct-current converter module 11 into low-voltage direct current. The power distribution module 30 includes a dc power distribution submodule 31 electrically connected to the output of the low voltage dc conversion submodule 21 for supplying power to the load device 40. The first high-voltage direct-current converter module 11, the low-voltage direct-current conversion submodule 21 and the direct-current power distribution submodule 31 form a direct-current power supply branch 1A of the power supply system 1.
In one specific example, the first hvdc converter module 11 is used to convert the three-phase ac power with the voltage value of 10kV inputted from the high voltage distribution system into the high voltage dc power of 750V, and transmit the high voltage dc power to the low voltage dc converter module 21. The low-voltage dc conversion submodule 21 is configured to convert the high-voltage dc into 240V low-voltage dc, and transmit the low-voltage dc to the dc power distribution submodule 31. The dc power distribution submodule 31 distributes and transmits 240V low-voltage dc power to each cabinet load, so as to implement dc power distribution of the dc power supply branch 1A. The dc power distribution submodule 31 may be a dc rail cabinet.
It is understood that the power supply system 1 may include one dc power supply branch 1A, and may also include a plurality of dc power supply branches 1A. The number of the direct current power supply branch circuits 1A can be set according to the number of cabinet loads of the data center and direct current power utilization requirements.
Through the scheme, the direct current power supply requirement of the power supply system 1 on the data center load equipment 40 can be realized. Compared with a power supply architecture in the related art, the high-voltage power distribution equipment, the low-voltage power distribution equipment and the high-voltage direct-current equipment are required to be arranged to realize the multi-stage voltage conversion of the direct-current power supply, the voltage conversion of the direct-current power supply can be realized only through the first high-voltage direct-current converter module 11 and the low-voltage direct-current conversion submodule 21 in the embodiment of the disclosure, the power supply power loss can be further reduced, and the equipment cost can be further reduced.
In one embodiment, as shown in fig. 1, the hvdc conversion module 10 includes a second hvdc conversion sub-module 12 for converting high voltage ac power input from the high voltage power distribution system to high voltage dc power. The low-voltage conversion module 20 comprises a low-voltage alternating current conversion submodule 22, which is electrically connected with the output end of the second high-voltage direct current conversion submodule 12 and is used for converting the high-voltage direct current output by the second high-voltage direct current conversion submodule 12 into low-voltage alternating current. The power distribution module 30 includes an ac power distribution submodule 32 electrically connected to the output of the low voltage ac conversion submodule 22 for supplying power to the load device 40. The second hvdc converter module 12, the low-voltage ac conversion submodule 22 and the ac power distribution submodule 32 form an ac power supply branch 1B of the power supply system 1.
In one specific example, the second hvdc conversion submodule 12 is configured to convert three-phase ac power with a voltage value of 10kV input to the high voltage distribution system into high voltage dc power of 750V, and transmit the high voltage dc power to the low voltage ac conversion submodule 22. The low-voltage ac conversion submodule 22 is configured to convert the high-voltage dc power into a low-voltage ac power of 220V, and transmit the low-voltage ac power to the ac power distribution submodule 32. The ac power distribution submodule 32 distributes and delivers the low-voltage ac power of 220V to each cabinet load, so as to implement dc power distribution of the dc power supply branch 1A.
It is understood that the power supply system 1 may include one ac power supply branch 1B, or may include a plurality of ac power supply branches 1B. The number of the alternating current power supply branches 1B can be specifically set according to the number of the cabinet loads of the data center and the power consumption requirement.
It should be noted that the power supply system 1 may only be provided with the dc power supply branch 1A, and may also only be provided with the ac power supply branch 1B, and the dc power supply branch 1A and the ac power supply branch 1B may be specifically set according to the actual power demand of the data center.
Preferably, as shown in fig. 1, the power supply system 1 may include a dc power supply branch 1A and an ac power supply branch 1B. Therefore, the requirements of the data center cabinet load on direct current power supply and alternating current power supply can be met simultaneously. Moreover, when the ac power supply demand of the cabinet load of the data center is large, the ac power supply branch 1B only needs to perform voltage conversion on the ac power supply through the first high-voltage dc conversion sub-module 11 and the low-voltage ac conversion sub-module 22, so that the power supply efficiency is higher than that of the dc power supply branch 1A, and thus the overall power supply efficiency of the power supply system 1 can be improved.
In one embodiment, as shown in fig. 1, the load device 40 includes a complete rack 41 and a standard rack 42, and the complete rack 41 and the standard rack 42 are electrically connected to the output terminals of the power distribution module 30, respectively. The whole cabinet 41 is provided with a low-voltage power supply unit, the low-voltage power supply unit is used for converting low voltage into a direct-current communication power supply and outputting the direct-current communication power supply to a direct-current bus, and the voltage value of the direct-current communication power supply is 48V or 12V. The standard cabinet 42 is provided with a Power Distribution Unit (PDU) for distributing low voltage to each server.
Illustratively, the load device 40 may comprise a rack load. The rack load may include a complete rack 41 and a standard rack 42, and the complete rack 41 and the standard rack 42 are electrically connected to the power distribution module 30 by cables. The standard cabinet 42 is provided with a power distribution unit therein, and is configured to deliver the power distribution module 30 to the low voltage of the standard cabinet 42, distribute and deliver the low voltage to each server adapted to the voltage class of the low voltage. The entire cabinet 41 is provided with a server Power Supply Unit (PSU) for converting a low voltage input to the entire cabinet 41 into a dc Power having a voltage value of 48V, and transmitting the dc Power to a dc bus of the entire cabinet 41.
In one embodiment, the high voltage dc conversion module 10 is provided with an uninterruptible power supply 13 module, and the uninterruptible power supply 13 module is configured to output high voltage dc power in case of a power failure of the utility power.
For example, the uninterruptible power supply device 13 may employ a storage battery. The storage battery can output high-voltage direct current with a voltage value of more than 400V, for example, can output high-voltage direct current with a voltage value of 750V. Therefore, when the commercial power is cut off or the high-voltage distribution system breaks down, the uninterrupted power supply equipment 13 supplies power to the load equipment 40 of the data center, so that the data center can normally operate, and the working stability of the data center is improved.
In one embodiment, as shown in FIG. 3, the HVDC conversion module 10 and the low pressure conversion module 20 are integrated.
In one example, high voltage dc conversion module 10 and low voltage conversion module 20 may be adjacently disposed such that no long cable connections are required between high voltage dc conversion module 10 and low voltage conversion module 20.
In another example, the high voltage dc conversion module 10 and the low voltage conversion module 20 may be integrated in one cabinet. Specifically, as shown in fig. 2, the high-voltage dc conversion module 10 includes a first high-voltage dc conversion module 11 and a second high-voltage dc conversion module 12, and the low-voltage dc conversion module 20 includes a low-voltage dc conversion submodule 21 and a low-voltage ac conversion submodule 22. The first high-voltage direct-current conversion module 11 and the low-voltage direct-current conversion submodule 21 are integrated in one cabinet body, and the second high-voltage direct-current conversion module 12 and the low-voltage alternating-current conversion submodule 22 are integrated in one cabinet body. Therefore, the integration of the power supply system 1 can be improved, and the space occupied by the high-voltage direct-current conversion module 10 and the low-voltage conversion module 20 can be reduced.
In one embodiment, the low voltage conversion module 20 and the power distribution module 30 may be disposed adjacent to each other to reduce the efficiency loss during the transmission of the low voltage to the power distribution module 30, thereby further improving the power supply efficiency.
According to another aspect of the present disclosure, there is also provided a data center including the power supply system 1 according to the embodiment of the present disclosure.
According to the data center disclosed by the embodiment of the disclosure, by using the power supply system 1 disclosed by the embodiment of the disclosure, under the condition that the power supply power requirement of the load equipment 40 is increased, the higher power supply efficiency can still be ensured, so that the operation cost of the data center is reduced, and the equipment cost does not need to be increased.
