Technical Field

[0001] This utility model relates to the field of data center power supply, and more specifically, to a novel power supply architecture for intelligent computing centers. Background Technology

[0002] Power supply equipment is the core component of a data center's power distribution system, and its stable operation directly affects the reliability of power supply to IT loads. Regular maintenance of this equipment is therefore crucial.

[0003] Traditional data center power supply architecture: In order to achieve a core technical architecture with 99.999% power supply guarantee, a multi-level redundant, multi-path backup, and intelligent switching power supply system is generally constructed. A typical architecture includes: 2N mains power + 2N UPS + (N+X redundant) diesel generator. This architecture has disadvantages such as being relatively complex, cumbersome to operate and maintain, requiring a large number of devices, occupying a large area, having low UPS conversion efficiency, short battery life, and poor operational reliability.

[0004] Therefore, one or more methods are needed to solve the above problems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

The cabinet module includes an AC-DC rectifier module, a supercapacitor, and a cabinet. The cabinet module is used to input the incoming power to the cabinet through the AC-DC rectifier module and the supercapacitor.

[0055] The novel intelligent computing center power supply architecture in this example embodiment will be further described below.

[0056] Example 1:

[0057] The new intelligent computing center power supply architecture includes an A-path power supply module, a B-path power supply module, a diesel generator power supply module, and a server rack module, wherein:

[0060] The diesel generator power supply module is connected to both the A-line transformer and the B-line transformer.

It is also used to step down the voltage of the B-line emergency power supply through the B-line transformer, and then transmit the B-line power supply to the cabinet module through the B-line incoming cabinet, the B-line bus tie cabinet, and the B-line transfer cabinet.

[0061] The cabinet module includes an AC-DC rectifier module, a supercapacitor, and a cabinet. The cabinet module is used to input the power supply to the cabinet through the AC-DC rectifier module and the supercapacitor.

[0062] In this example embodiment, the power supply architecture further includes:

[0063] The A-line incoming cabinet and B-line incoming cabinet are busbar structures, and also include circuit breakers, current transformers, and voltage transformers.

[0064] In this example embodiment, the power supply architecture further includes:

[0065] The A-line bus tie cabinet and the B-line bus tie cabinet are connected by the bus tie main line. When the A-line mains power supply or the B-line mains power supply stops supplying power, the A-line bus tie cabinet or the B-line bus tie cabinet is enabled, and the A-line power supply module or the B-line power supply module is powered through the bus tie main line.

[0066] In this example embodiment, the power supply architecture further includes:

[0067] The A-channel and B-channel transfer cabinets are used to transmit the transformed power to the cabinet modules via the AC high-density busbar.

[0068] In this example embodiment, the power supply architecture further includes:

[0069] The cabinet module includes a preset number of sub-cabinet modules, and each sub-cabinet module includes an AC-DC rectifier module, a supercapacitor, and a cabinet.

[0070] In this example embodiment, the power supply architecture further includes:

[0071] The cabinet module includes an A-channel AC-DC rectifier module, an A-channel supercapacitor, a B-channel AC-DC rectifier module, a B-channel supercapacitor, a cabinet A-channel power supply port, and a cabinet B-channel power supply port.

[0072] In this example embodiment, the power supply architecture further includes:

[0073] The A-channel AC-DC rectifier module and the A-channel supercapacitor are connected to the cabinet respectively. The A-channel AC-DC rectifier module is used to convert the AC power input from the A-channel power supply module into DC power, and at the same time charge the A-channel supercapacitor and directly supply power to the A-channel power supply port of the cabinet.

[0074] In this example embodiment, the power supply architecture further includes:

[0075] The B-channel AC-DC rectifier module and the B-channel supercapacitor are connected to the cabinet respectively. The B-channel AC-DC rectifier module is used to convert the AC power input from the B-channel power supply module into DC power, and at the same time charge the B-channel supercapacitor and directly supply power to the B-channel power supply port of the cabinet.

[0076] In this example embodiment, the power supply architecture further includes:

[0077] like Figure 2The diagram shows the power supply status during normal operation. In normal operation: Power supply module A receives mains power and inputs it to AC-DC rectifier module A of the cabinet module; power supply module B receives mains power and inputs it to AC-DC rectifier module B of the cabinet module; AC-DC rectifier module A supplies power to power supply port A of the cabinet; AC-DC rectifier module B supplies power to power supply port B of the cabinet.

[0078] like Figure 3 The diagram shows the power supply status when the A-line mains power supply fails. In the A-line mains power supply failure state, after the A-line mains power supply failure occurs, the A-line supercapacitor supplies power to the A-line power supply port of the cabinet, enables the A-line bus tie cabinet and the B-line bus tie cabinet, and connects them through the bus tie main line to enable the B-line power supply module to supply power to the A-line power bus. The power supply to the A-line power supply port of the cabinet is switched to the A-line AC-DC rectifier module, and the A-line AC-DC rectifier module simultaneously charges the A-line supercapacitor.

[0079] like Figure 4 The diagram shows the power supply status when the B-channel mains power supply fails. In the B-channel mains power supply failure state, after the B-channel mains power supply failure occurs, the B-channel supercapacitor supplies power to the B-channel power supply port of the cabinet, enabling the A-channel bus tie cabinet and the B-channel bus tie cabinet.

[0081] In this example embodiment, the power supply architecture further includes:

[0082] like Figure 6 The diagram shows the power supply status when the A-channel AC-DC rectifier module fails. When the A-channel AC-DC rectifier module fails, the faulty rectifier module unit sets the power supply architecture to the A-channel mains power supply failure state, thus completing the replacement of the A-channel AC-DC rectifier module.

[0083] When the B-channel AC-DC rectifier module fails, the faulty rectifier module unit sets the power supply architecture to the B-channel mains power failure state, thus completing the replacement of the B-channel AC-DC rectifier module.

[0084] like Figure 7 The diagram shows the power supply status when the supercapacitor in circuit A fails. When a supercapacitor fails, the disabled supercapacitor will be directly taken offline and replaced.

[0085] Example 2:

[0086] In this example embodiment, the new intelligent computing center power supply architecture includes one 2500kVA dry-type transformer, one incoming line cabinet (containing one 5000A frame circuit breaker), one bus tie cabinet (containing one 4000A frame circuit breaker), one busbar transfer cabinet (containing only busbars, without switches), four sets of AC dense busbars, and 72 sets of DC terminal modules (modules are configured according to the number of cabinets); the B line has the same configuration.

[0087] In this example embodiment, the connection path of the power supply equipment under the traditional architecture is as follows: the transformer to the incoming cabinet is connected by a busbar; the incoming cabinet to the bus tie cabinet, UPS input / output cabinet, and UPS cabinet is connected by a busbar; the UPS input / output cabinet to the feeder cabinet and maintenance bypass cabinet is connected by a busbar; the UPS cabinet to the battery switch cabinet of the storage battery is connected by a DC compact busbar; the feeder cabinet to the rack head cabinet is connected by a compact busbar; and the rack head cabinet to the cabinet is connected by a multi-core cable. This connection path is numerous and complex, requiring a large amount of on-site construction, and also presents many potential faults and risks. Under the new architecture, the connection path of the power supply equipment is: transformer... The incoming line cabinet is connected to the busbar, and the incoming line cabinet, bus tie cabinet, and busbar transfer cabinet are connected to the busbar. The busbar transfer cabinet is connected to the power supply terminal via a compact busbar. This architecture mainly consists of busbar and compact busbar connections, which is simple and greatly reduces on-site construction and potential fault points. The new architecture optimizes and reduces the number of power supply equipment. AC power supply equipment maintenance mainly targets transformers and distribution cabinets with fewer maintenance items. At the same time, the distribution cabinet only retains the incoming line cabinet and bus tie cabinet, which only involves two frame circuit breakers. Other physical connections are compact busbars and copper busbars, which greatly reduces equipment maintenance work.

[0088] In this example embodiment, the new architecture still adopts a 2N redundancy design, a 2N mains power + 2N DC terminal power supply architecture. This architecture also includes two completely independent power supply links (usually referred to as "A-path" and "B-path"). Each path consists of "mains input + power distribution unit + DC terminal module", and the two paths are physically isolated (independent cables, buses, switches, etc.). Taking the two 2500kVA mains power + two DC terminal power supply architectures shown in the figure below as an example, taking path A as an example, path A consists of one 2500kVA dry-type transformer, one 5000A incoming line cabinet, one 4000A bus tie cabinet, and one combiner cabinet, which are arranged in the power distribution room. Through dense busbars, the mains power of path A is directly sent to the server room module in the white area of ​​the data center to power the DC terminal of each rack. The DC terminal consists of an AC-DC rectifier power supply module and a supercapacitor module. Both modules are rack-mounted and directly installed in the rack.

[0089] In this example embodiment, the traditional architecture requires a power distribution room and a separate battery room due to the large number of power supply devices. These rooms necessitate additional equipment such as fire protection, HVAC, lighting, cable trays, and intelligent systems. Taking the aforementioned dual 2500kVA AC mains power + dual UPS architecture as an example, the total area required for power supply equipment A and B is 657m². 2 ;

[0090] Under the new architecture, most of the equipment in the UPS unit and power distribution unit of the traditional architecture has been optimized and reduced. Taking the architecture of two 2500kVA mains power supply + two DC terminal power supply as an example, the power supply equipment only requires one power distribution room, and the total area required for A and B is 80m². 2 It saves 87.8% of the floor space compared to the traditional architecture. At the same time, due to the elimination of the battery room, the lighting and fire protection systems involved in the battery room are also eliminated. The added DC terminal modules are installed in the cabinet and do not occupy the power distribution area.

[0091] Under the new power supply architecture, the overall planning and layout of intelligent computing centers will undergo significant changes. In traditional intelligent computing centers, the area ratio of the power distribution room to the computer room area is already 1:1 or even 2:1, with the power distribution room accounting for more than 2 / 3 of the entire intelligent computing center area. Furthermore, as the power density of the computer room area of ​​the intelligent computing center further increases, the area occupied by the power distribution room will further increase. Under the new power supply architecture, the area ratio of the power distribution room to the computer room area is already 1:8, and the area occupied by the power distribution room is significantly reduced.

[0092] Within the same area of ​​the intelligent computing center, it can accommodate up to four times more server room area and server racks, significantly increasing the output of the intelligent computing center.

[0093] In this example embodiment, compared to the traditional architecture, the new architecture reduces the power distribution equipment to 1 / 4 of the original, directly reducing the UPS and battery room, and the area of ​​the power distribution area is reduced to 1 / 8 of the original.

[0094] If we only consider the investment in power distribution equipment, the two architectures are basically on par. If we also consider the savings in building area and the increased revenue from the increased output of the intelligent computing center's server room, the new architecture will significantly reduce the overall investment in the intelligent computing center, and the owner's TCO will be greatly reduced.

[0095] In the future, with the large-scale application of supercapacitors in the industry, the price of supercapacitors is expected to decrease further, the cost advantage of the new architecture will become more prominent, and the total cost of ownership (TCO) of the new architecture will decrease significantly.

[0096] In this example embodiment, the novel power supply architecture uses supercapacitors as backup power, while the traditional architecture uses a UPS plus a battery as backup power. Supercapacitors and batteries differ significantly in their usage. The impact on the system is primarily determined by the following characteristics.

[0097] A) Supercapacitors exhibit double-layer or quasi-capacitive effects and do not involve chemical reactions; storage batteries involve chemical reactions and have poor stability.

[0098] B) Supercapacitors have high instantaneous power and fast response speed; batteries have a slower charging and discharging speed and require conversion through a UPS.

[0099] C) The supercapacitor is directly connected to the IT load without any other conversion; the UPS needs to convert AC to DC and then DC to AC to power the IT load. During the conversion process, some electrical energy is lost as heat, resulting in low conversion efficiency.

[0100] D) Supercapacitors can withstand tens of thousands to hundreds of thousands of cycles and require almost no maintenance; storage batteries can withstand thousands of cycles and need to be replaced regularly.

[0101] Due to the combined effects of the factors mentioned above, the new architecture has higher efficiency and longer service life.

[0102] In the embodiments of this example, as Figure 8 The diagram shows the power supply architecture of route A. Taking route A as an example, route A consists of one 2500kVA dry-type transformer, one 5000A incoming line cabinet, one 4000A bus tie cabinet, and one combiner switch cabinet. It is arranged in the power distribution room and sends the mains power of route A directly to the computer room module in the white area of ​​the data center through the dense bus. It supplies power to the DC end of route A of each rack. The DC end consists of an AC-DC rectifier power supply module and a supercapacitor module. Both modules are rack-mounted and directly installed in the rack.

[0103] In this example embodiment, the normal operating state is as follows:

[0104] Dual independent mains power supplies are supplied simultaneously, connected to mains power from two different substations (or different busbars of the same substation). This ensures that if one mains power supply is interrupted due to a grid fault (such as a substation outage or line maintenance), the other mains power supply can still provide normal power. Both mains power supplies must meet the "no risk of co-source faults," meaning that simultaneous interruptions due to grid faults in the same area should be avoided. Mains power supply A is connected to the high-voltage side of the A-type dry-type transformer. The low-voltage side of the transformer is connected to the incoming side of the incoming line cabinet via a copper busbar. The copper busbar on the outgoing side of the incoming line cabinet is connected to the incoming side of the bus tie cabinet and the copper busbar of the busbar transfer cabinet. The copper busbar of the busbar transfer cabinet is connected to the compact busbar to deliver mains power A to the DC terminal in the cabinet. Mains power supply B operates on the same principle as mains power A.

[0105] In the DC terminal system, the DC terminal consists of an AC-DC rectifier module and a supercapacitor module. The AC-DC rectifier module converts the mains power (A-channel) into DC power, part of which is used for float charging of the supercapacitor, and the other part is stably output to the load.

[0106] The diesel generator is in "hot standby" mode, with a full fuel tank, the start-up system on standby, and real-time monitoring of the status of the mains power and DC terminal system.

[0107] In this example embodiment, a single mains power failure occurs:

[0108] If the mains power supply to route A fails and is interrupted, the incoming frame circuit breaker in the incoming line cabinet of route A will trip, and the supercapacitor of route A will immediately switch to "discharge mode" (millisecond-level switching). At this time, the power supply ports of route A in the cabinet are all powered by the supercapacitor of route A in this cabinet. Meanwhile, the mains power supply of route B will still normally supply power to the DC terminal and load of route B.

[0109] If the mains power failure on route A continues, and if it is foreseeable that the supercapacitor's operating time on route A will be exceeded, the PLC controller will close the frame circuit breakers in the bus tie cabinets of routes A and B. According to the closing logic program, the incoming frame circuit breaker in the incoming line cabinet of route A cannot close at this time, to ensure that if the mains power on route A is suddenly restored, the incoming frame circuit breaker in the incoming line cabinet of route A will not suddenly close, thus avoiding the risk of phase merging between the transformers of route A and route B. Since the frame circuit breakers in the bus tie cabinets of routes A and B are closed, the DC terminal and load of route A are powered by the mains power of route B, and the supercapacitor of route A enters "charging mode." The DC terminal and load of route B are still powered by the mains power of route B, that is, the mains power of route B bears 100% of the load. If the mains power on route B is interrupted, its working principle is the same as the mains power failure interruption logic of route A.

[0110] In this example embodiment, both mains power supplies are interrupted simultaneously:

[0111] Phase 1 (0-90 seconds): Both mains power supply lines A and B fail simultaneously. The supercapacitors on lines A and B immediately switch to "discharge mode" (millisecond-level switching). At this time, power supply ports on line A of the cabinet are powered by the supercapacitors on line A within the same cabinet, and power supply ports on line B of the cabinet are powered by the supercapacitors on line B within the same cabinet, ensuring continuous operation of the load. Simultaneously, the control system triggers the diesel generator set's generator start signal.

[0112] Phase Two (After Diesel Generator Set Start-up): The diesel generator set starts up within 60 seconds and outputs a stable power supply. Through the PLC controller, the high-voltage side of transformers A and B is switched from AC mains power to diesel generator set power. At this time, the AC-DC rectifier module at the DC end of transformer A resumes operation, converting the AC power generated by the diesel generator set into DC power. Part of this DC power is used to charge the supercapacitor in transformer A, and the other part is stably output to the load in transformer A. Similarly, the AC-DC rectifier module at the DC end of transformer B resumes operation, converting the AC power generated by the diesel generator set into DC power. Part of this DC power is used to charge the supercapacitor in transformer B, and the other part is stably output to the load in transformer B.

[0113] Long-term operation: The diesel generator set provides continuous power until mains power is restored. After mains power is restored, the system automatically switches back to mains power supply, and the diesel generator set stops and stands by. If both mains power lines are restored simultaneously, mains power line A supplies power to the DC terminals and loads of line A, while mains power line B supplies power to the DC terminals and loads of line B; this is a dual-line independent mains power supply mode. If only one mains power line is restored, both DC terminals and loads are powered by the restored mains power line; this is a single mains power line carrying 100% of the load mode.

[0114] In this example embodiment, the DC end fault is:

[0115] If a single supercapacitor module in power supply port A of the cabinet fails, since the load on port A is normally powered by AC mains power on port A and the AC-DC rectifier module at the DC end of port A, simply replacing the faulty supercapacitor module will not affect the load on port A. The same applies to port B.

[0116] If a single AC-DC rectifier module in the A power supply port of the rack fails, the supercapacitor of the A line will immediately switch to "discharge mode" (millisecond-level switching). After the A line supercapacitor's battery life is exceeded, the server will continue to obtain power through the B power interface (the server's dual power supply design ensures that a single power outage will not affect operation). After replacing the faulty AC-DC rectifier module, it will switch to the normal dual-line independent AC mains power supply mode.

[0117] In this example embodiment, DC end maintenance:

[0118] Since both the AC-DC rectifier module and the supercapacitor module at the DC end are rack-mounted, they are easy to install and maintain.

[0119] When a module fails, the faulty module can be directly removed from the rack and replaced with a new one, making maintenance convenient.

[0120] In the traditional architecture, taking DC-related equipment such as UPS and battery packs as examples, maintenance is relatively complicated and requires many precautions when a fault occurs.

[0121] When the UPS fails, first switch the power supply system to "maintenance bypass", disconnect the UPS input and output circuit breakers, replace the faulty module, perform a no-load test first to confirm that the UPS is operating normally (such as normal switching between AC mode and battery mode), and then gradually connect the load.

[0122] When the battery fails, first disconnect the battery switch cabinet, remove the connecting copper busbars / cables between the batteries one by one, take out the old batteries, install the new batteries according to the original wiring method (series or parallel), ensure the polarity is correct, measure the total voltage of the battery pack to confirm that it is consistent with the nominal voltage, and connect the UPS for testing.
