Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply system, and particularly relates to a power supply module and a data center. BACKGROUND

[0002] In the power supply architecture of the traditional data center, in order to ensure the safety during power failure, a UPS power supply is arranged in the computer room to provide uninterrupted power supply for the data center. For example, when the commercial power is abnormal or interrupted, the UPS power supply can automatically switch to the battery power supply mode to protect the connected devices from damage. The UPS power supply can ensure the continuous operation of the data center, provide backup power through the battery pack, and usually can maintain the power supply time for tens of minutes to several hours to ensure that the equipment can continue to operate before the commercial power is restored. The UPS power supply can also stabilize the commercial power when the commercial power is normal, output high-quality power supply, and charge the battery at the same time. However, the UPS power supply is composed of rectifiers, inverters, static switches, battery packs and other components, which has a large volume and occupies the placement space of the data center, thereby reducing the space utilization of the data center.

[0014] This invention proposes a power supply module and a data center. The data center includes electrical equipment. The power supply module includes a mains power input terminal for connecting to mains power, an equipment rack, an energy storage module (including a PCS and an energy storage battery), a diesel generator, and a DPS power system (including a battery). The power supply rack has dual buses for connecting to the mains power input terminal; the energy storage module is connected to the mains power input terminal through the PCS module; the DPS power system is located inside the equipment rack and is connected to the dual buses, with its output connected to the electrical equipment.

The diesel generator can also be activated as needed. This invention installs a smaller-capacity DPS power system inside the equipment rack, while a larger-capacity energy storage module is installed outside the equipment room. In the event of a mains power failure or anomaly, the DPS provides short-term discharge to ensure uninterrupted power supply, while the energy storage module provides backup power for a longer period. This leverages the energy storage characteristics to reduce operating costs through peak shaving and valley filling, and provides ample time for the diesel generator to start. Furthermore, the DPS battery capacity can be significantly reduced, thus minimizing the space occupied by the equipment rack. This tiered backup power and emergency power supply scheme achieves better space utilization, a more favorable cost-performance ratio, and a more reliable solution. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Understandably, in traditional data center power supply architectures, to ensure safety during power outages, the power modules within the racks integrate UPS (Uninterruptible Power Supply) units to provide uninterrupted power. For example, when the mains power in the power module is abnormal or interrupted, the UPS can automatically switch to battery power mode, protecting connected equipment from damage. Simultaneously, the UPS ensures the continuous operation of the data center, providing backup power through its built-in battery pack, typically maintaining power for tens of minutes to several hours, ensuring equipment can continue operating until mains power is restored. The UPS can also stabilize the mains power when it is normal, outputting high-quality power while charging the batteries. However, UPS power supplies consist of components such as rectifiers, inverters, static switches, and battery packs, making them relatively large and occupying space in the data center, reducing space utilization.

[0029] Therefore, in order to save space occupied by power supply modules in data centers, this invention proposes a power supply module for use in data centers, wherein the data center includes electrical equipment, as shown in the reference. Figure 2 The power supply module includes:

[0030] It has a mains power connection terminal for connecting to mains power;

[0031] A power supply rack having a double row of busbars for connecting to the mains power input terminal;

[0032] PCS energy storage system 10, wherein the PCS energy storage system 10 is connected to the mains power access terminal;

[0033] DPS power system 20, the DPS power system 20 is installed inside the power supply rack, the DPS power system 20 is connected to the double busbar, and the DPS power system 20 is connected to the power-consuming equipment;

[0034] When the mains power fails, the DPS power system 20 starts first and supplies power to the electrical equipment, and the PCS energy storage system 10 starts later and supplies power to the electrical equipment through the double busbars.

[0035] Understandably, in traditional data center power supply architectures, to ensure safety during power outages, large spaces are required to integrate UPS power supplies within the rack's power supply modules. Large-scale integrated UPS power supplies are typically expensive, potentially increasing construction and operating costs for data centers with limited budgets. Furthermore, data center rack space is usually limited, and installing large-scale integrated UPS power supplies can occupy significant space, affecting the installation and layout of other equipment. It should be noted that while UPS power supplies provide backup power, they themselves can fail. If a UPS power supply fails, it can cause a complete power outage for the entire rack. To maintain stable power supply to the data center while saving space occupied by power supply modules, this invention replaces the UPS power supply inside the power supply rack with a smaller capacity PCS energy storage system 10, and installs a larger capacity DPS power system 20 outside the power supply rack. The stable power supply to the data center is achieved through the combined operation of the DPS power system 20 inside the power supply rack and the PCS energy storage system 10 outside the power supply rack. This not only reduces the space occupied by the power supply modules in the data center but also improves the reliability and scalability of the power supply modules.

[0036] In this embodiment, the power supply module includes a mains power input terminal, a power supply rack, a PCS energy storage system 10, and a DPS power system 20. The PCS energy storage system 10 is located outside the power supply rack and connected to the mains power input terminal; the DPS power system 20 is located inside the power supply rack and connected to the dual-row bus and the power-consuming equipment. When the mains power is in a normal supply state, the power voltage output from the mains power flows sequentially through the mains power input terminal, the dual-row bus, and the DPS power system 20 before finally being output to the power-consuming equipment, thus realizing the function of direct mains power supply to the data center. When the mains power fails, that is, when the mains power is in an abnormal supply state, the DPS power system 20 responds quickly and outputs power voltage to the power-consuming equipment to ensure that the equipment does not suddenly lose power and operates in a temporarily stable state. During the process of the DPS power system 20 supplying power to the electrical equipment, the PCS energy storage system 10 starts up. Its output power voltage is sequentially delivered to the electrical equipment through the mains power input terminal, the dual busbars, and the DPS power system 20, ultimately achieving the effect of the DPS power system 20 and the PCS energy storage system 10 jointly supplying power to the data center. With this configuration, this embodiment replaces the UPS power supply inside the power rack with the smaller-capacity PCS energy storage system 10, and installs the larger-capacity DPS power system 20 outside the power rack. The DPS power system 20 inside the power rack provides priority power supply, while the PCS energy storage system 10 outside the power rack provides power later, ensuring the continuity and stability of power supply to the data center. This not only reduces the space occupied by the power supply modules in the data center but also improves the reliability and scalability of the power supply modules.

[0037] Furthermore, when one of the two mains power sources fails, it briefly supplies power to the load; when both inputs fail, it provides uninterrupted power to the load until the inputs are restored to normal power (mains power is restored or the PCS energy storage system 10 discharges). That is, when one mains power source fails, the switching unit switches the input of the DPS power system 20 from the failed source to the other normal mains power source; when both sources fail, the DPS power system 20 supplies power, and the switching unit does not need to operate in this case.

[0038] It is important to understand that the DPS power system 20 includes a DPS conversion circuit, which is implemented using a dynamic power supply circuit. This circuit is primarily used to quickly respond to power changes in the power supply module, enabling power switching or adjustment within a short time. For example, the dynamic power supply circuit can quickly activate upon detecting mains power fluctuations or circuit faults to ensure the short-term stable operation of the power supply module and maintain the continuity of power supply to the equipment. The PCS energy storage system 10 includes a PCS conversion circuit, which is implemented using an energy storage converter. This circuit is primarily used for energy conversion between the battery pack in the power supply module and the mains power or load. Its operation often involves more complex control logic and a larger-scale energy conversion process. For example, when the energy storage converter detects a mains power outage, it not only needs to perform energy conversion but also needs to consider multiple factors such as battery status, protection mechanisms, and coordination with other systems. This makes its response require relatively more time for comprehensive judgment and preparation. Therefore, when the mains power fails, the DPS power system 20 responds quickly and prioritizes power supply to the electrical equipment, while the PCS energy storage system 10 starts later, ultimately achieving the effect of DPS power system 20 and PCS energy storage system 10 jointly supplying power.

[0039] In another embodiment, reference Figure 1The power supply module is equipped with a diesel generator circuit diagram and also includes a relay K and an ATS (Automatic Transfer Switch). The first terminal of relay K is connected to the mains input 2. The first terminal of the ATS is connected to both the PCS energy storage system 10 and the second terminal of relay K. The second terminal of the ATS is connected to the diesel generator, and the third terminal of the ATS is connected to the double-row busbar. It's important to understand that when the mains power is normal, the PCS energy storage system 10 is controlled to meet grid response requirements, enabling peak shaving and valley filling applications, or it is kept in hot standby mode to ensure uninterrupted power supply to the load during any mains power failure. Because the PCS energy storage system 10 can quickly respond to changes in power demand, it can rapidly release energy to maintain the stable operation of the data center when the power load of electrical equipment increases instantaneously or when there are brief fluctuations in the grid. Its response time is typically in the millisecond range, providing immediate power support to electrical equipment. On the other hand, the diesel generator has a long continuous power supply capability. In the event of a prolonged power outage, the diesel generator can start and continuously provide power to the data center. It can serve as a primary backup power source, ensuring the normal operation of the data center for extended periods. Therefore, when the PCS energy storage system 10 and the diesel generator simultaneously supply power to the data center as backup power modules, they can complement each other's strengths. For example, in the initial stages of a fault, the PCS energy storage system 10 can immediately provide power, buying time for the diesel generator to start. Once the diesel generator is running, it can handle the primary power supply task, while the PCS energy storage system 10 can supplement it, continuing to provide power support when the diesel generator fails or requires maintenance. Therefore, controlling the start of the PCS energy storage system 10, followed by the start of the diesel generator, allows the PCS energy storage system 10 to respond instantly and provide power. When the mains power fails or needs switching, it can immediately fill the power gap, achieving seamless switching and ensuring power continuity. In practical applications, when the mains power is abnormal, the control relay K disconnects the path between the mains input 2 and the PCS energy storage system 10, thus preventing a short circuit between the mains 380Vac and the PCS energy storage system 10 output when the mains power recovers. The ATS (Automatic Power Supply) first switches the connection between the PCS (Power Storage System) 10 and the electrical equipment, and then starts the PCS 10 and the diesel generator. Initially, the PCS 10 outputs voltage to the electrical equipment. Once the diesel generator starts successfully and its output power is stable, the ATS switches the connection between the diesel generator and the electrical equipment, allowing the diesel generator to supply power to the data center. This makes the diesel generator a backup power module for the electrical equipment. This configuration prevents unstable shutdowns during diesel generator power supply, thus ensuring the continuity of backup power.

[0040] This invention proposes a power supply module for use in a data center, which includes electrical equipment. The power supply module includes a mains power input terminal for connecting to mains power, a power supply rack, a PCS energy storage system 10, and a DPS power system 20. The power supply rack has a double-row busbar for connecting to the mains power input terminal; the PCS energy storage system 10 is connected to the mains power input terminal; the DPS power system 20 is located inside the power supply rack, connected to the double-row busbar, and connected to the electrical equipment. In practical applications, when the mains power fails, the DPS power system 20 responds quickly and outputs power voltage to the electrical equipment, operating in a briefly stable state. The PCS energy storage system 10 starts later and outputs power sequentially through the mains power input terminal, the double-row busbar, and the DPS power system 20 to the electrical equipment, achieving the effect of both the DPS power system 20 and the PCS energy storage system 10 jointly powering the data center. This invention replaces the UPS power supply inside the power supply rack with a smaller capacity PCS energy storage system 10, and installs a larger capacity DPS power system 20 outside the power supply rack. The DPS power system 20 inside the power supply rack provides priority power supply, while the PCS energy storage system 10 outside the power supply rack provides power supply with a delay, ensuring the continuity and stability of power supply to the data center. This not only reduces the space occupied by the power supply module in the data center, but also improves the reliability and scalability of the power supply module.

[0041] In one embodiment, reference is made to Figure 2 The capacity of the battery pack in the DPS power system 20 is lower than the capacity of the battery pack in the PCS energy storage system 10.

[0042] It is understandable that the battery capacity inside the DPS power system 20 should be lower than the battery capacity inside the PCS energy storage system 10. This allows the use of power-type cells in the DPS power system 20 and energy-type cells in the PCS energy storage system 10. Furthermore, due to the limited space in data center power racks, installing a large-capacity integrated UPS power supply would occupy a significant amount of space and weight. To save space occupied by power modules in the data center and improve space utilization, in this embodiment, the battery capacity in the DPS power system 20 is set to be lower than that in the PCS energy storage system 10. This arrangement allows the larger-capacity PCS energy storage system 10 to be placed outside the power rack, reducing the weight of the power rack and saving space. For the internal space of the power rack, removing the large-capacity battery pack frees up space, making the internal layout of the power rack more flexible and reducing congestion caused by the battery pack occupying space.

[0043] In one embodiment, reference is made to Figure 3The mains power access terminal includes a first mains power access terminal and a second mains power access terminal. The dual-row busbar includes a first busbar and a second busbar. The first mains power access terminal is connected to the first busbar, and the second mains power access terminal is connected to the second busbar. The PCS energy storage system 10 includes:

[0044] PCS conversion circuit 11 and first battery pack 12, wherein PCS conversion circuit 11 is connected to the second mains power input terminal and PCS conversion circuit 11 and first battery pack 12 are connected;

[0045] The PCS conversion circuit 11 is used to convert the mains power at the second mains power input terminal to power the first battery pack 12 when the second mains power input terminal is normally powered, and to convert the voltage of the first battery pack 12 to power the electrical equipment when the second mains power input terminal loses power.

[0046] Understandably, in this embodiment, to prevent data centers from immediately losing mains power and causing service interruptions due to line faults such as line damage, substation failures, or unexpected power outages, a first mains power access terminal and a second mains power access terminal are provided. The first mains power access terminal is used to connect to the first mains power supply, and the second mains power access terminal is used to connect to the second mains power supply, achieving the effect of dual mains power supply. With dual mains power supply, if one mains power supply fails, the other mains power supply can continue to power the data center, greatly reducing the power outage time caused by mains power failures and ensuring the continuous operation of the data center. Furthermore, dual mains power supply can provide a larger total power supply capacity to meet the power supply needs of the power modules under high load or peak demand.

[0047] Furthermore, in this embodiment, the PCS conversion circuit 11 and the first battery pack 12 are located outside the power supply rack, and the PCS conversion circuit 11 is connected to the second mains power input terminal. The PCS conversion circuit 11 and the first battery pack 12 are used together to realize the conversion and storage of electrical energy. The PCS conversion circuit 11 is specifically implemented using an energy storage converter. When the second mains power fails, the PCS conversion circuit 11 can switch to battery power supply mode, convert the battery voltage of the first battery pack 12 from DC to AC, and then output it. The AC power output by the PCS conversion circuit 11 passes through the second mains power input terminal and the first bus DPS power system 20 in sequence, and is finally output to the power-consuming equipment to provide emergency power supply for the power-consuming equipment, ensure the continuous operation of the power-consuming equipment, avoid data center business interruption or equipment damage caused by the failure of the second mains power, and greatly improve the continuity and stability of power supply.

[0048] In one embodiment, reference is made to Figure 3The DPS power system 20 includes: a mains connection line, a first connection line, and a conversion circuit 30. The conversion circuit 30 includes a DPS conversion circuit 31 and a second battery pack 32.

[0049] The mains connection line is used to connect the second busbar and the electrical equipment, and the first connection line is used to connect the mains connection line and the DPS conversion circuit 31;

[0050] The DPS conversion circuit 31 is connected to the first bus, the second battery pack 32 and the electrical equipment respectively; the DPS conversion circuit 31 is used to convert the voltage of the second battery pack 32 into voltage and output it to power the electrical equipment when both the first mains power input terminal and the second mains power input terminal lose power.

[0051] It is understood that, in this embodiment, reference is made to... Figure 3 The DPS power system 20 consists of an AC power connection line, a first connection line, a DPS conversion circuit 31, and a second battery pack 32. The DPS conversion circuit 31 is implemented using a dynamic power supply circuit, which is mainly used to quickly respond to power changes in the power supply module and can switch or adjust the power in a short time.

[0052] In practical applications, the DPS conversion circuit 31 internally includes a first voltage monitoring circuit for continuous real-time monitoring of the mains voltage connected to the first and second buses. This first voltage monitoring circuit has a set voltage threshold range. When the mains voltage detected by the first voltage monitoring circuit is within the voltage threshold range, it is determined that the mains power is in a normal connection state. When the mains voltage detected by the first voltage monitoring circuit exceeds the voltage threshold range, such as when the detected mains voltage is lower than the lower limit of the normal operating voltage or close to zero, it will determine that the mains power connection is abnormal. For example, if the voltage range is set to 220V ± 10% (i.e., 198V - 242V), when the voltage value detected by the first voltage monitoring circuit is lower than 198V or no voltage is detected at all, it will determine that the mains power connection is abnormal. The DPS conversion circuit 31 also includes a first control circuit. When an abnormality is detected in the mains power connection, the first control circuit of the DPS conversion circuit 31 performs DC-AC conversion or DC-DC conversion on the voltage of the second battery pack 32, and outputs the processed voltage of the second battery pack 32 to the power-consuming equipment to supply power to the equipment. When the DPS conversion circuit 31 is an AC DPS conversion circuit 31, the first control circuit of the AC DPS conversion circuit 31 performs DC-AC conversion on the voltage of the second battery pack 32 and outputs it to supply power to the power-consuming equipment; when the DPS conversion circuit 31 is a DC DPS conversion circuit 31, the first control circuit of the DC DPS conversion circuit 31 performs DC-DC conversion on the voltage of the second battery pack 32 and outputs it to supply power to the power-consuming equipment.

[0053] It is important to understand that since the DPS conversion circuit 31 is connected to both the first bus and the second bus via the first connecting line, and the DPS conversion circuit 31 is connected to the mains voltages of both the first and second mains power supplies via the first and second buses, when the DPS conversion circuit 31 determines that the mains power connection is abnormal, it means that both the first and second mains power supply terminals are de-energized. This configuration, by establishing a connection between the first and second buses via the first connecting line, ensures that the DPS conversion circuit 31 is only allowed to output voltage when both the first and second mains power supplies are de-energized. This ensures that when the first and second mains power supplies are functioning normally, the DPS conversion circuit 31 is in a standby state and will not output voltage arbitrarily, avoiding unnecessary energy consumption and potential system interference. It effectively prevents voltage conflicts between the mains voltage and the voltage of the DPS conversion circuit 31, avoiding problems such as current reverse flow and voltage instability that could affect the normal operation of the power supply module, thus increasing the reliability, stability, and emergency response capability of the DPS conversion circuit 31.

[0054] In one embodiment, reference is made to Figure 4 The DPS power system 20 includes: a first AC converter circuit 40, a second AC converter circuit 50, and a switching unit 80;

[0055] The input terminals of the switching unit 80 are connected to the first bus and the second bus respectively, and the output terminals of the switching unit 80 are connected to the first AC conversion circuit 40 and the second AC conversion circuit 50 respectively. The output terminal of the first AC conversion circuit 40 is connected to the electrical equipment, and the output terminal of the second AC conversion circuit 50 is connected to the electrical equipment.

[0056] The switching unit 80 is used to control the first and second mains power access terminals to supply power to the electrical equipment when the first mains power access terminal or the second mains power access terminal is normally powered, and to switch the input of the DPS power system 20 to the second mains power access terminal or the first mains power access terminal when the first mains power access terminal or the second mains power access terminal loses power, so as to use the mains power to supply power to the electrical equipment.

[0057] Understandably, when either the first or second AC power input fails, the DPS power system 20 input is switched to either the second or first AC power input. This allows the DPS power system 20 to utilize AC power as much as possible to supply power to the load and reduces battery discharge time. In other words, when one AC power input fails, the corresponding DPS power system 20 operates in battery discharge mode for a short period, providing uninterrupted short-term power to the load. When both AC power inputs fail, the DPS provides uninterrupted power to the load through battery discharge until the input power is restored (either through AC power or PCS discharge). With this setup, the battery needs to support continuous power supply to the load during switching unit transitions, without requiring the battery to power the load for extended periods, thus reducing battery capacity and size and saving rack space.

[0058] The first AC converter circuit 40 includes a first AC DPS circuit 41 and a third battery pack 42, and the second AC converter circuit 50 includes a second AC DPS circuit 51 and a fourth battery pack 52.

[0059] The output terminal of the switching unit 80 is connected to the first AC DPS circuit 41 and the second AC DPS circuit 51 respectively. The first AC DPS circuit 41 is connected to the third battery pack 42 and the electrical equipment respectively. The second AC DPS circuit 51 is connected to the fourth battery pack 52 and the electrical equipment respectively.

[0060] The first AC DPS circuit 41 is used to convert the voltage of the third battery pack 42 and output it to power the electrical equipment.

[0061] The second AC converter circuit 50 is used to convert the voltage of the fourth battery pack 52 and output it to power the electrical equipment.

[0062] It is understood that, in this embodiment, reference is made to... Figure 4 The DPS power system 20 consists of two AC conversion circuits and a switching unit 80. The first AC conversion circuit 40 includes a first AC DPS circuit 41 and a third battery pack 42, and the second AC conversion circuit 50 includes a second AC DPS circuit 51 and a fourth battery pack 52.

[0063] In practical applications, the switching unit 80 is used to switch to normal mains power supply when one mains power supply fails; when both mains power supplies are disconnected, the switching unit 80 does not work and controls the output voltage of the first AC conversion circuit 40 and the second AC conversion circuit 50.

[0064] For example, when the first mains voltage is within the voltage threshold range, it is determined that the first mains power is in a normal connection state. When the second mains voltage exceeds the voltage threshold range, it is determined that the second mains power connection is abnormal, and the switching unit 80 switches to the first mains power supply. Conversely, when the first mains power is abnormal, the switching unit 80 switches to the second mains power supply. When both mains power supplies are disconnected, the DPS power system supplies power. The first AC DPS circuit 41 and the second AC DPS circuit 51 act as conversion devices, converting the voltage of the battery packs into a suitable AC voltage for output to the power-consuming equipment. Specifically, the first AC DPS circuit 41 starts and performs DC-AC conversion on the voltage of the third battery pack 42 before outputting it to power the power-consuming equipment. The second AC DPS circuit 51 starts and performs DC-AC conversion on the voltage of the fourth battery pack 52 before outputting it to power the power-consuming equipment. In this way, by setting up two AC conversion circuits, the effect of two-way AC voltage conversion is achieved. When one AC voltage conversion fails, the other AC voltage conversion can continue to supply power to the data center, ensuring the continuous operation of the data center.

[0078] It is understood that, in this embodiment, reference is made to... Figure 6 The output of the fifth battery pack 62 is connected to the output of the first DC DPS circuit 61, and their interconnection points are connected to the power-consuming equipment. Simultaneously, the output of the sixth battery pack 72 is connected to the output of the second DC DPS circuit 71, and their interconnection points are connected to the power-consuming equipment. This combination of the fifth and sixth battery packs provides the power supply module with four power supply paths.
