Description

Technical Field

[0001] This application relates to the field of power supply and distribution technology, specifically to a power supply architecture, power supply method, power supply device, and readable storage medium. Background Technology

[0002] Data centers typically employ a 2N+ high- and low-voltage bus tie power supply architecture. The high-voltage bus tie provides mutual backup for two high-voltage power supplies, while the low-voltage bus tie provides mutual backup for two sets of low-voltage busbars. However, in practice, this architecture has several drawbacks. Preventative testing of high-voltage equipment requires shutting down one power supply circuit for testing. If the other power supply circuit fails under single-load conditions, it can lead to a dual power outage for the end-point IT equipment. Furthermore, short-circuit faults in downstream equipment can cause malfunctions in the high-voltage side circuit breaker. After switching via the bus tie, the fault can propagate to the other power supply circuit, and due to identical protection configurations, this can trigger interlocking tripping. Summary of the Invention

[0003] This application provides a power supply architecture, power supply method, power supply device, and readable storage medium. By connecting a first power supply circuit and a second power supply circuit connected to each other at low voltage busbars to two different devices to be powered, the two power supply circuits that supply power to the same device to be powered are made completely independent.

[0004] This application provides a power supply architecture, including:

[0005] The mains power terminal includes a first mains power terminal and a second mains power terminal, and the first mains power terminal and the second mains power terminal are connected by a high-voltage bus.

[0006] The power supply system includes a plurality of first power supply circuits and the same number of second power supply circuits as the first power supply circuits. The high-voltage terminals of the plurality of first power supply circuits are electrically connected to the first mains terminal, and the high-voltage terminals of the plurality of second power supply circuits are electrically connected to the second mains terminal. The low-voltage terminals of the plurality of first power supply circuits are respectively connected to the low-voltage terminals of the plurality of second power supply circuits in a one-to-one low-voltage bus tie.

[0007] The number of devices to be powered is the same as that of the first power supply circuit. Each device to be powered is electrically connected to a low-voltage terminal of the first power supply circuit and a low-voltage terminal of the second power supply circuit. The first power supply circuit and the second power supply circuit, which are interconnected by a low-voltage bus, are electrically connected to two different devices to be powered.

[0008] The power supply architecture provided in this application connects the first and second power supply circuits, which are mutually connected to low-voltage busbars, to two different devices to be powered. This achieves complete independence of the two power supply circuits that supply power to the same device. Furthermore, a fault in one power supply circuit will not affect the normal power supply of the other power supply circuit, thus providing more time for maintenance, reducing maintenance difficulty, and improving the reliability of the power supply architecture.

[0009] In some embodiments, the power supply architecture further includes a backup power supply, which includes a first output terminal and a second output terminal. The first output terminal of the backup power supply is electrically connected to the high-voltage terminal of the plurality of first power supply circuits, and the second output terminal of the backup power supply is electrically connected to the high-voltage terminal of the plurality of second power supply circuits.

[0010] In this way, by setting up a backup power supply and connecting its output terminals to the high-voltage terminals of the first power supply module and the second power supply module respectively, the diesel generator set can supply power to all loads when the mains power fails simultaneously, thus avoiding the shutdown of the equipment to be powered due to the mains power interruption and ensuring the continuity of power supply.

[0011] In some embodiments, the power supply architecture further includes a first circuit breaker and a second circuit breaker, wherein the first output terminal of the backup power supply is electrically connected to the high-voltage terminal of the plurality of first power supply circuits through the first circuit breaker, and the second output terminal of the backup power supply is electrically connected to the high-voltage terminal of the plurality of second power supply circuits through the second circuit breaker.

[0012] Thus, by setting up a first circuit breaker and a second circuit breaker between the output end of the diesel generator set and the power supply module, independent control and protection of the diesel generator set's power supply circuit are achieved. This facilitates rapid isolation during diesel generator set maintenance or failure, prevents the fault from spreading to the high-voltage power distribution system, and improves operation and maintenance safety.

[0013] In some embodiments, the first power supply circuit includes a transformer, the primary side of which is electrically connected to the first mains power terminal, and the secondary side of which is electrically connected to the device to be powered.

[0014] Thus, by setting up a transformer in the first power supply circuit, the conversion from the mains voltage to the voltage applicable to the equipment to be powered is realized. At the same time, through the electrical isolation between the primary and secondary sides of the transformer, the impact of harmonic interference on the mains side on the load is reduced, ensuring the quality of power supply.

[0015] In some embodiments, the first power supply circuit further includes a third circuit breaker and a fourth circuit breaker, wherein the primary side of the transformer is electrically connected to the first mains terminal through the third circuit breaker, and the secondary side of the transformer is electrically connected to the device to be powered through the fourth circuit breaker.

[0016] Thus, by setting a third circuit breaker and a fourth circuit breaker on the primary and secondary sides of the transformer respectively, independent protection of the transformer's input and output circuits is achieved. When there is an internal fault in the transformer or a short circuit on the load side, the corresponding circuit can be quickly disconnected to prevent the fault from spreading to the mains power terminal or other power supply circuits, thereby improving system safety.

[0017] A second embodiment of this application provides a power supply method for a power supply architecture. The power supply architecture includes a mains power terminal, a power supply system, and devices to be powered. The mains power terminal includes a first mains power terminal and a second mains power terminal, with the first mains power terminal and the second mains power terminal connected by a high-voltage bus. The power supply system includes a plurality of first power supply circuits and the same number of second power supply circuits as the first power supply circuits. The high-voltage terminals of the plurality of first power supply circuits are electrically connected to the first mains power terminal, and the high-voltage terminals of the plurality of second power supply circuits are electrically connected to the second mains power terminal. The low-voltage terminals of the plurality of first power supply circuits are connected to the low-voltage terminals of the plurality of second power supply circuits one-to-one via low-voltage bus connections. The number of devices to be powered is the same as the number of first power supply circuits. Each device to be powered is electrically connected to a low-voltage terminal of one first power supply circuit and a low-voltage terminal of one second power supply circuit. The first power supply circuits and second power supply circuits connected by mutual low-voltage bus connections are electrically connected to two different devices to be powered. The power supply method includes:

[0018] The operating status of the first power supply circuit or the second power supply circuit that supplies power to at least one of the devices to be powered is obtained;

[0019] In response to determining an abnormal power supply circuit in the first power supply circuit or the second power supply circuit based on the operating state, power is supplied to the device to be powered corresponding to the abnormal power supply circuit through another first power supply circuit or the second power supply circuit that supplies power to the device to be powered corresponding to the abnormal power supply circuit.

[0020] In this way, two completely independent power supply circuits are set up for the device to be powered, and if the operation of one of them is abnormal, the other power supply circuit is switched to power the device to be powered, thereby improving the reliability of the power supply architecture.

[0021] A third embodiment of this application provides a power supply device for a power supply architecture, characterized in that the power supply architecture includes a mains power terminal, a power supply system, and devices to be powered. The mains power terminal includes a first mains power terminal and a second mains power terminal, with the first mains power terminal and the second mains power terminal connected by a high-voltage bus.

The high-voltage terminals of the plurality of first power supply circuits are electrically connected to the first mains power terminal, and the high-voltage terminals of the plurality of second power supply circuits are electrically connected to the second mains power terminal. The low-voltage terminals of the plurality of first power supply circuits are connected by a low-voltage bus corresponding to the low-voltage terminals of the plurality of second power supply circuits. The number of devices to be powered is the same as the number of first power supply circuits. Each device to be powered is electrically connected to a low-voltage terminal of one first power supply circuit and a low-voltage terminal of one second power supply circuit. The first power supply circuits and second power supply circuits connected by mutual low-voltage bus are electrically connected to two different devices to be powered. The power supply device includes:

[0022] The acquisition module is used to acquire the operating status of the first power supply circuit or the second power supply circuit that supplies power to at least one of the devices to be powered.

[0023] A switching module is configured to, in response to determining, based on the operating state, an abnormal power supply circuit in the first power supply circuit or the second power supply circuit that is abnormally powered, supply power to the device to be powered corresponding to the abnormal power supply circuit through another first power supply circuit or the second power supply circuit that supplies power to the device to be powered corresponding to the abnormal power supply circuit.

[0044] Data centers typically employ a 2N+ high- and low-voltage bus tie-up power supply architecture (2N power supply architecture refers to two independent power supply systems (such as two sets of mains input, two sets of transformers, two sets of UPS, etc.), each capable of carrying 100% load, forming a fully redundant "dual power supply, dual path" power supply mode). The high-voltage bus tie-up provides mutual backup for the two high-voltage power supplies, while the low-voltage bus tie-up provides mutual backup for the two low-voltage busbars. However, in practice, this architecture has several drawbacks. Preventative testing of high-voltage equipment requires shutting down one power supply circuit for testing. If the other power supply circuit fails under single-path load, it can lead to a dual-path power outage for the end-point IT equipment. Furthermore, short-circuit faults in downstream equipment can cause malfunctions in the high-voltage side circuit breaker. After bus tie-up switching, the fault can propagate to the other power supply circuit, and due to identical protection configurations, this can lead to interlocking tripping. In addition, complex fault scenarios (such as simultaneous tripping of two high-voltage circuit breakers) demand extremely high levels of expertise from maintenance personnel, and delayed fault handling can easily result in service interruptions.

[0045] Please see Figure 1This application provides a power supply architecture 100, including a mains terminal 10, a power supply system 20, and devices to be powered 30. The mains terminal 10 includes a first mains terminal 11 and a second mains terminal 12, with high-voltage bus connections between the first mains terminal 11 and the second mains terminal 12. The power supply system 20 includes a plurality of first power supply circuits 21 and a number of second power supply circuits 22 equal to the number of first power supply circuits 21. The high-voltage terminals of the plurality of first power supply circuits 21 are electrically connected to the first mains terminal 11, and the high-voltage terminals of the plurality of second power supply circuits 22 are electrically connected to the second mains terminal 12. The low-voltage terminals of the plurality of first power supply circuits 21 are connected to low-voltage bus connections one-to-one with the low-voltage terminals of the plurality of second power supply circuits 22. The number of devices to be powered 30 is the same as the number of first power supply circuits 21. Each device to be powered 30 is electrically connected to a low-voltage terminal of a first power supply circuit 21 and a low-voltage terminal of a second power supply circuit 22. The first power supply circuits 21 and the second power supply circuits 22 connected to each other via low-voltage bus connections are electrically connected to two different devices to be powered 30.

[0046] The power supply architecture 100 provided in this application connects the first power supply circuit 21 and the second power supply circuit 22, which are interconnected by low-voltage busbars, to two different devices 30 to be powered. This achieves complete independence of the two power supply circuits that supply power to the same device 30. Furthermore, when one power supply circuit fails, it will not affect the normal power supply of the other power supply circuit. This provides more time for maintenance, helps to reduce maintenance difficulty, and improves the reliability of the power supply architecture 100.

[0047] In this embodiment of the application, the high-voltage bus tie refers to the installation of a tie switch on the high-voltage distribution side (such as the 10kV mains input section) to enable two high-voltage power supplies to serve as backups for each other, supporting fault isolation or planned maintenance and repair.

[0048] Low-voltage bus tie refers to the installation of a tie switch on the low-voltage distribution side (such as the 400V output section) to achieve mutual power backup between two sets of low-voltage busbars, support fault isolation or planned maintenance, and enhance the power supply continuity of end loads (such as servers, switches, etc.).

[0049] The power supply architecture 100 achieves dual-active redundancy power supply to the equipment 30 to be powered through the design of dual mains terminals 10 high-voltage bus tie and dual power supply circuit cross bus tie. Specifically, the first mains terminal 11 and the second mains terminal 12 are connected by a high-voltage bus tie switch 40, forming two independent high-voltage power supply channels; the number of the first power supply circuit 21 and the second power supply circuit 22 corresponds one-to-one with the equipment 30 to be powered, and the low-voltage end of each pair of power supply circuits is connected by a low-voltage bus tie switch 50, but each pair of power supply circuits is connected to different equipment 30 to be powered. In this way, the two power supply circuits supplying power to the same equipment (one from the first power supply circuit 21 and the other from the second power supply circuit 22) can be completely physically isolated. When either power supply circuit fails (such as transformer 211 failure or line short circuit), the other power supply circuit can immediately take over the load, and the fault will not spread to the other system.

[0050] In some embodiments, taking the power supply circuit of two sets of low-voltage bus couplers as an example, such as... Figure 2 As shown, the first power supply circuit 21 includes circuits A1 and A2. The high-voltage terminals of circuits A1 and A2 are connected to the first mains terminal 11. The second power supply circuit 22 includes circuits B1 and B2. The high-voltage terminals of circuits B1 and B2 are connected to the second mains terminal 12. The low-voltage terminals of circuits A1 and B2 are connected via a low-voltage bus, and the low-voltage terminals of circuits A2 and B1 are also connected via a low-voltage bus. The device to be powered 30 includes a first device and a second device. Circuits A1 and B1 are connected to the first device to supply power, and circuits A2 and B2 are connected to the second device to supply power. When the power supply architecture 100 is in operation, if circuit A1 fails and power is interrupted, the corresponding first device can automatically switch to power supply from circuit B1. Furthermore, since there is no low-voltage bus connection between circuits A1 and B1, a fault at the A1 circuit end will not affect circuit B1.

[0051] In some embodiments, taking the power supply circuit of three sets of low-voltage bus couplers as an example, such as... Figure 3As shown, the first power supply circuit 21 includes circuits A1, A2, and A3. The high-voltage terminals of circuits A1, A2, and A3 are all connected to the first mains terminal 11. The second power supply circuit 22 includes circuits B1, B2, and B3. The high-voltage terminals of circuits B1, B2, and B3 are connected to the second mains terminal 12. The low-voltage terminals of circuits A1, B1, A2, and B3 are connected together. The low-voltage terminals of circuits A3 and B3 are connected together. The device to be powered 30 includes a first device, a second device, and a third device. Circuits A1 and B3 are connected to the first device to supply power to the first device. Circuits A2 and B1 are connected to the second device to supply power to the second device. Circuits A3 and B2 are connected to the third device to supply power to the third device.

[0052] In some embodiments, taking the power supply circuit of four low-voltage bus couplers as an example, such as... Figure 4 As shown, the first power supply circuit 21 includes circuits A1, A2, A3, and A4. The high-voltage terminals of circuits A1, A2, A3, and A4 are all connected to the first mains terminal 11. The second power supply circuit 22 includes circuits B1, B2, B3, and B4. The high-voltage terminals of circuits B1, B2, B3, and B4 are connected to the second mains terminal 12. The low-voltage terminals of circuits A1 and B1 are connected via a low-voltage bus, and the low-voltage terminals of circuits A2 and B2 are connected via a low-voltage bus. Low-voltage busbar connection, low-voltage busbar connection between the low-voltage ends of circuit A3 and B3, low-voltage busbar connection between the low-voltage ends of circuit A4 and B4, the equipment to be powered 30 includes a first device, a second device, a third device and a fourth device, circuits A1 and B4 are connected to the first device to supply power to the first device, circuits A2 and B1 are connected to the second device to supply power to the second device, circuits A3 and B2 are connected to the third device to supply power to the third device, and circuits A4 and B3 are connected to the fourth device to supply power to the fourth device.

[0053] In some embodiments, the power supply architecture 100 further includes a backup power supply 60, which includes a first output terminal 61 and a second output terminal 62. The first output terminal 61 of the backup power supply 60 is electrically connected to the high-voltage terminals of a plurality of first power supply circuits 21, and the second output terminal 62 of the backup power supply 60 is electrically connected to the high-voltage terminals of a plurality of second power supply circuits 22.

[0054] In this way, by setting up a backup power supply 60 and connecting its output terminals to the high-voltage terminals of the first power supply module and the second power supply module respectively, the diesel generator set can supply power to all loads when the mains power supply 10 fails simultaneously, thus preventing the standby equipment 30 from shutting down due to the mains power interruption and ensuring the continuity of power supply.

[0055] Specifically, in this embodiment, the power supply architecture 100 adds a backup power supply 60, connecting its first output terminal 61 and second output terminal 62 to the high-voltage terminals of the first power supply circuit 21 and the second power supply circuit 22 respectively, forming a dual power supply system of "mains power + backup power supply 60". When the mains power supply 10 is completely interrupted due to a fault, the backup power supply 60 can be started immediately, supplying power to the first power supply circuit 21 and the second power supply circuit 22 through the high-voltage terminal, ensuring the continuous operation of the equipment 30 to be powered.

[0056] In some embodiments, the number of backup power supplies 60 can be set to multiple, and the multiple backup power supplies 60 are connected in parallel to further improve the reliability of the power supply architecture 100.

[0057] In some embodiments, the backup power source 60 includes at least one of a steam turbine generator, a hydro turbine generator, a diesel generator, a gasoline generator, a wind turbine generator, and a gas turbine generator.

[0058] Thus, by configuring the backup power supply 60 as at least one of several types, such as steam turbine generator, hydro turbine generator, and diesel generator, the backup power supply 60 can be diversified, making it easy to flexibly adapt the optimal backup power supply 60 solution according to actual scenarios (such as resource conditions, environmental requirements, and cost budget). At the same time, the redundant configuration of multiple types of backup power supplies 60 reduces the risk of power outage caused by the failure of a single type of equipment, and improves the fault tolerance and long-term operational stability of the power supply architecture 100.

[0059] Specifically, in this embodiment, the specific type of backup power source 60 can be selected based on the actual needs and environmental advantages of the power supply architecture 100. For example, in areas rich in hydropower resources, hydroelectric generators can be prioritized as backup power sources 60, which meets environmental protection requirements and reduces operating costs; while in remote areas with abundant oil resources, diesel generators can be prioritized to provide more stable power support.

[0060] In this embodiment, the backup power supply 60 supports a combination configuration of various types of backup power supplies 60, that is, it allows the simultaneous deployment of multiple different types of generators (such as diesel generators + wind turbines), thereby forming a redundant system with complementary technologies. When any type of generator fails, the remaining units can still bear the entire load, avoiding the risk of "single point of failure". This not only adapts to resource constraints and cost requirements under different scenarios, but also improves the long-term operational stability of the system through technological diversity, providing a wider range of choices for the large-scale application of the power supply architecture 100.

[0061] Please see Figure 1In some embodiments, the power supply architecture 100 further includes a first circuit breaker 70 and a second circuit breaker 80. The first output terminal 61 of the backup power supply 60 is electrically connected to the high-voltage terminals of a plurality of first power supply circuits 21 through the first circuit breaker 70, and the second output terminal 62 of the backup power supply 60 is electrically connected to the high-voltage terminals of a plurality of second power supply circuits 22 through the second circuit breaker 80.

[0062] Thus, by setting up a first circuit breaker 70 and a second circuit breaker 80 between the output end of the diesel generator set and the power supply module, independent control and protection of the diesel generator set's power supply circuit are achieved. This facilitates rapid isolation during diesel generator set maintenance or failure, prevents the fault from spreading to the high-voltage power distribution system, and improves operation and maintenance safety.

[0063] Specifically, the first output terminal 61 and the second output terminal 62 of the backup power supply 60 are connected to the high-voltage terminals of the first power supply circuit 21 and the second power supply circuit 22 through the first circuit breaker 70 and the second circuit breaker 80, respectively, realizing refined control of the power supply circuit of the backup power supply 60. For example, when the backup power supply 60 needs to be maintained regularly, maintenance personnel can disconnect the corresponding circuit breaker to physically isolate the backup power supply 60 from the power supply system 20, avoiding the impact of maintenance operations on operating equipment; when a short circuit or overcurrent fault occurs at the output terminal of the backup power supply 60, the circuit breaker can quickly disconnect the fault circuit to prevent abnormal current from spreading to the mains side or other power supply modules. In this way, it is beneficial to improve the maintainability and fault isolation capability of the system, especially suitable for power supply scenarios with high load and complex topology. Through the independent operation of the first circuit breaker 70 and the second circuit breaker 80, the system can ensure continuous power supply while realizing rapid handling of local faults, reducing the overall operation and maintenance risk and cost.

[0064] Please see Figure 5 In some embodiments, the first power supply circuit 21 includes a transformer 211, the primary side of which is electrically connected to the first mains terminal 11, and the secondary side of which is electrically connected to the device to be powered 30.

[0065] Thus, by setting a transformer 211 in the first power supply circuit 21, the conversion from the mains voltage to the applicable voltage of the device to be powered 30 is realized. At the same time, through the electrical isolation between the primary and secondary sides of the transformer 211, the impact of harmonic interference on the mains side on the load is reduced, thus ensuring the power supply quality.

[0066] Specifically, in this embodiment, the transformer 211 in the first power supply circuit 21 is a key component for voltage conversion and electrical isolation. Its primary side is directly connected to the first mains terminal 11, converting the high voltage of the mains power (e.g., 10kV) into the low voltage (e.g., 400V) required by the device to be powered 30, thus meeting the voltage adaptation requirements of different loads.

[0067] In this embodiment, the power supply equipment is typically a server rack (a rack is the infrastructure that houses hardware such as servers, network devices, and power modules). Since server racks are precision devices, they are significantly affected by interference signals. Transformer 211 can achieve electrical isolation between the primary and secondary sides through electromagnetic induction, effectively blocking the transmission of interference signals such as harmonics and surges from the mains power side to the load end, thus improving power quality. For example, when there are voltage fluctuations or harmonic pollution in the mains power grid, transformer 211 can filter out high-frequency noise, providing a cleaner power environment for the server rack.

[0068] In some embodiments, the first power supply circuit 21 further includes a third circuit breaker 212 and a fourth circuit breaker 213. The primary side of the transformer 211 is electrically connected to the first mains terminal 11 through the third circuit breaker 212, and the secondary side of the transformer 211 is electrically connected to the device to be powered 30 through the fourth circuit breaker 213.

[0069] Thus, by setting a third circuit breaker 212 and a fourth circuit breaker 213 on the primary and secondary sides of transformer 211 respectively, independent protection of the input and output circuits of transformer 211 is achieved. When there is an internal fault in transformer 211 or a short circuit on the load side, the corresponding circuit can be quickly disconnected to prevent the fault from spreading to the mains terminal 10 or other power supply circuits, thereby improving system safety.

[0070] In this embodiment, the third circuit breaker 212 and the fourth circuit breaker 213 installed on the primary and secondary sides of transformer 211 constitute a dual protection mechanism for the transformer 211 itself. Specifically, the third circuit breaker 212 is located on the primary side (i.e., the mains side) of transformer 211. When a short circuit or overvoltage fault occurs at the first mains terminal 11, it can quickly disconnect the primary circuit to prevent the fault current from damaging the transformer 211 windings. The fourth circuit breaker 213 is located on the secondary side of transformer 211. When a short circuit or load abnormality occurs in the equipment 30 to be powered, it can immediately disconnect the secondary connection to prevent the fault from spreading to transformer 211 or the mains system. For example, when the equipment 30 to be powered causes a short circuit on the secondary side due to misoperation, the fourth circuit breaker 213 can operate within milliseconds, limiting the fault to a local circuit while ensuring the normal operation of both the mains side and the primary side transformer 211. In this way, not only is the risk of equipment damage reduced, but the fault diagnosis time is also reduced through rapid isolation, improving the overall system availability.

[0071] In some embodiments, the first power supply circuit 21 further includes an uninterruptible power supply 214, which is electrically connected between the secondary side of the transformer 211 and the device 30 to be powered.

[0072] Thus, by introducing an uninterruptible power supply 214 into the first power supply circuit 21, seamless power supply is achieved when the mains power is interrupted or switched to the diesel generator, avoiding momentary power outages of the equipment 30 to be powered due to power switching.

[0073] Specifically, an uninterruptible power supply (UPS) is a system composed of a converter, switch, and energy storage device that outputs AC or DC power to maintain the continuity of power supply to the load for a certain period of time when the input power supply is normal or faulty. The uninterruptible power supply 214 introduced in the first power supply circuit 21 can be used to ensure the continuity of power supply.

[0074] In this embodiment, the uninterruptible power supply 214 is electrically connected between the secondary side of the transformer 211 and the device 30 to be powered. It can seamlessly switch to battery power at the moment of mains power interruption or switching to backup power 60 (usually less than 10 milliseconds), avoiding downtime or data loss of the device 30 due to power interruption. For example, during the switching process between mains power and backup power 60, the uninterruptible power supply 214 can convert DC power into stable AC power through an inverter to provide continuous power support for precision equipment.

[0075] Furthermore, in this embodiment, the power supply equipment is typically a server rack, which is significantly affected by voltage fluctuations. The uninterruptible power supply 214 also functions as a voltage regulator, automatically stabilizing the output voltage when the mains voltage fluctuates (such as overvoltage or undervoltage) to ensure stable voltage at the load end. Thus, by filling the "gap" between the mains power and the backup power supply 60, zero-interruption power supply is achieved, significantly improving system reliability.

[0076] In some embodiments, the first power supply circuit 21 further includes a battery 215, which is electrically connected to the uninterruptible power supply 214.

[0077] Thus, by configuring the uninterruptible power supply 214 with a storage battery 215, continuous energy storage support for the uninterruptible power supply 214 is achieved. When neither the mains power nor the diesel generator can supply power, the storage battery 215 can extend the power supply time of the uninterruptible power supply 214, providing maintenance personnel with a window for troubleshooting and reducing the risk of business interruption.

[0078] Specifically, in this embodiment, configuring a battery 215 for the uninterruptible power supply 214 helps it maintain continuous power supply capability. When both the mains power and the backup power supply 60 are unavailable, the battery 215 can provide emergency power to the load through the uninterruptible power supply 214. For example, if the backup power supply 60 fails to start or the mains power restoration is delayed, the battery 215 can extend the power supply time of the uninterruptible power supply 214, providing maintenance personnel with a window of opportunity for troubleshooting and system recovery. Furthermore, the capacity of the battery 215 can be flexibly configured according to load requirements to meet the endurance requirements in different scenarios. This facilitates deep protection against extreme failures and reduces the risk of business interruption.

[0079] In some embodiments, the first power supply circuit 21 further includes a fifth circuit breaker 216 and a sixth circuit breaker 217. One end of the uninterruptible power supply 214 is electrically connected to the secondary side of the transformer 211 through the fifth circuit breaker 216, and the other end of the uninterruptible power supply 214 is electrically connected to the device 30 to be powered through the sixth circuit breaker 217.

[0080] Thus, by setting a fifth circuit breaker 216 and a sixth circuit breaker 217 at both ends of the uninterruptible power supply 214, independent protection and isolation of the input and output circuits of the uninterruptible power supply 214 are achieved. When the uninterruptible power supply 214 fails, it can be quickly disconnected by the circuit breaker to avoid the fault affecting the transformer 211 or the equipment 30 to be powered. At the same time, it facilitates the online maintenance of the uninterruptible power supply 214 and improves the maintainability of the system.

[0081] Specifically, the fifth circuit breaker 216 and the sixth circuit breaker 217 installed at both ends of the uninterruptible power supply 214 form an independent protection system for the uninterruptible power supply 214 module. The fifth circuit breaker 216 is located at the input end of the uninterruptible power supply 214. When a fault occurs inside the uninterruptible power supply 214 or the input voltage is abnormal, it can quickly disconnect the connection between the uninterruptible power supply 214 and the transformer 211, preventing fault current from damaging upstream equipment. The sixth circuit breaker 217 is located at the output end of the uninterruptible power supply 214. When the equipment 30 to be powered experiences a short circuit or overcurrent, it can immediately disconnect the connection between the uninterruptible power supply 214 and the load, preventing the fault from spreading to the uninterruptible power supply 214 itself. For example, when the uninterruptible power supply 214 experiences an abnormal output due to a software fault, the sixth circuit breaker 217 can quickly act, limiting the fault to a local circuit while ensuring the normal operation of the transformer 211 side and other loads. This configuration achieves refined control and isolation of the uninterruptible power supply 214 module.

[0082] In some embodiments, the fifth circuit breaker 216 and the sixth circuit breaker 217 are also provided to facilitate the online maintenance of the uninterruptible power supply 214. Maintenance personnel can repair or replace the uninterruptible power supply 214 by disconnecting the fifth circuit breaker 216 and the sixth circuit breaker 217 without interrupting the overall power supply, which significantly improves the maintainability of the system.

[0083] In some embodiments, the first power supply circuit 21 further includes a header cabinet 218, which is electrically connected between the uninterruptible power supply 214 and the device 30 to be powered.

[0084] In this way, by setting up a power distribution cabinet 218 between the uninterruptible power supply 214 and the equipment to be powered 30, centralized power distribution and monitoring of the end loads are realized, which facilitates unified management of the power distribution of multiple sets of equipment. At the same time, the monitoring module built into the power distribution cabinet 218 can provide real-time feedback of current and voltage data of each branch, providing a basis for fault location and capacity planning, and improving the manageability of the system.

[0085] Specifically, a remote power panel (RPP) refers to a cabinet that provides power distribution management, arranged in rows or divided by functional areas.

[0086] In this embodiment, the power distribution unit 218 is electrically connected between the uninterruptible power supply 214 and the equipment 30 to be powered, serving as a power distribution hub to uniformly allocate power resources. The power distribution unit 218 has a built-in monitoring module that can collect parameters such as current, voltage, and power of each branch in real time and upload the data to the operation and maintenance system via a communication interface. For example, when the current of a branch exceeds a threshold, the power distribution unit 218 can trigger an alarm and record the abnormal time, helping maintenance personnel quickly locate the fault point.

[0087] In this embodiment of the application, the first power supply circuit 21 further includes a seventh circuit breaker 219, and the cabinet 218 is connected to the uninterruptible power supply 214 through the seventh circuit breaker 219.

[0088] In some embodiments, the power distribution unit 218 can support a multi-level power distribution architecture, allowing for flexible adjustment of the number and capacity of branches according to load requirements, accommodating equipment access of different scales. This not only simplifies the complexity of end-point power distribution but also enhances system manageability through centralized monitoring, providing data support for capacity planning and energy efficiency optimization.

[0089] In some embodiments, the first power supply circuit 21 and the second power supply circuit 22 have the same structure.

[0090] Thus, by designing the first power supply circuit 21 and the second power supply circuit 22 to have the same structure, the complete symmetry and standardization of the two power supply systems 20 are achieved, avoiding the problem of unbalanced protection or inconsistent performance caused by differences in circuit structure; at the same time, the symmetrical structure ensures that the redundancy capabilities of the two power supplies are completely equivalent, and when one fails, the other can seamlessly take over the entire load, further enhancing the fault tolerance and reliability of the power supply architecture 100.

[0091] In this embodiment, the first power supply circuit 21 and the second power supply circuit 22 are completely identical in terms of component configuration (such as transformer 211, circuit breaker, uninterruptible power supply 214), electrical parameters (such as voltage conversion ratio, protection threshold), and connection method (such as bus tie position), ensuring the equivalence of the redundant system. For example, when the first power supply circuit 21 is out of service due to a fault, the second power supply circuit 22 can seamlessly take over its entire load without adjusting protection parameters or reconfiguring the topology. This symmetrical design avoids protection imbalance caused by circuit differences (such as false tripping or failure to trip caused by different operating thresholds of a certain circuit breaker), significantly improving the fault tolerance of the system.

[0092] Specifically, the second power supply circuit 22 consists of a transformer 211, an uninterruptible power supply (UPS) 214, a storage battery 215, and a power supply cabinet 218. The primary side of the transformer 211 is electrically connected to the second mains terminal 12 via a third circuit breaker 212, and simultaneously electrically connected to the second output terminal 62 of the backup power supply 60 via a second circuit breaker 80. The secondary side of the transformer 211 is electrically connected to the input terminal of the UPS 214 via a fourth circuit breaker 213 and a fifth circuit breaker 216. The output terminal of the UPS 214 is electrically connected to the power supply cabinet 218 via a sixth circuit breaker 217 and a seventh circuit breaker 219, and the storage battery 215 is connected to the UPS 214. The output terminal of the power supply cabinet 218 is electrically connected to the corresponding equipment 30 to be powered.

[0093] In some embodiments, the fact that the first power supply circuit 21 and the second power supply circuit 22 have the same structure also helps to reduce production and maintenance costs. Maintenance personnel can perform maintenance on both circuits based on the same set of operating procedures, which reduces the difficulty of training and spare parts management.

[0094] Please see Figure 6 , Figure 6 This is a flowchart illustrating a power supply method provided in an embodiment of this application. It should be noted that the steps shown may be executed in a logical order different from that shown in the flowchart. The power supply method includes the following steps:

[0095] Step 110: Obtain the operating status of the first power supply circuit or the second power supply circuit that supplies power to at least one device to be powered.

[0096] In this embodiment of the application, the operating state of the first power supply circuit 21 or the second power supply circuit 22 can be determined by obtaining parameters such as voltage, current, and power of the first power supply circuit 21 or the second power supply circuit 22.

[0097] In other embodiments, the operating state of the first power supply circuit 21 or the second power supply circuit 22 can be determined by obtaining other parameters of the first power supply circuit 21 or the second power supply circuit 22 according to the actual usage.

[0098] Step 120: In response to determining an abnormal power supply circuit in the first or second power supply circuit based on the operating status, power is supplied to the device to be powered corresponding to the abnormal power supply circuit through another first or second power supply circuit that supplies power to the device to be powered corresponding to the abnormal power supply circuit.

[0099] In this way, two completely independent power supply circuits are set up for the device to be powered 303, and when the operating state of one of them is abnormal, the other power supply circuit is switched to supply power to the device to be powered 30, thereby improving the reliability of the power supply architecture 100.

[0100] For example, the operating status of the first power supply circuit 21 or the second power supply circuit 22 that supplies power to a device 30 to be powered can be obtained. When the operating status of the first power supply circuit 21 is abnormal, the power supply circuit 22 will be switched to supply power to the device 30 to be powered. When the operating status of the second power supply circuit 22 is abnormal, the power supply circuit 21 will be switched to supply power to the device 30 to be powered.

[0101] In this embodiment, the power supply method significantly improves the power supply reliability of the device 30 to be powered through redundancy design. Specifically, the power supply method first acquires in real time the operating status information of two completely independent first power supply circuits 21 and second power supply circuits 22 serving at least one specific device 30 to be powered. This operating status information typically includes key parameters such as the output voltage, output current, and on / off status of the first power supply circuit 21 or the second power supply circuit 22. When the system analyzes this acquired status information and determines that one of the circuits (e.g., the first power supply circuit 21) has a power supply abnormality (such as a significant deviation of the output voltage from the rated value, an abnormal increase in output current indicating overload or short circuit, or a complete circuit interruption), the power supply method immediately triggers a control response. This response automatically controls another normally operating circuit (i.e., the second power supply circuit 22) that supplies power to the same device 30 (the device to be powered) corresponding to the abnormal power supply circuit (the first power supply circuit) to start operation or maintain its operating state, with the second power supply circuit 22 taking over and continuing to provide the required power to the device to be powered. This ensures that even if one power supply path fails, the critical load can be seamlessly maintained through its independent backup path, thereby effectively avoiding equipment downtime caused by single point of failure and significantly enhancing the reliability and availability of the entire power supply architecture 100.

[0102] Please see Figure 7 In some embodiments, the power supply method further includes:

[0103] Step 130: Obtain the power supply status of the mains power supply;

[0104] In this embodiment of the application, the power supply status of the mains terminal 10 can be determined by acquiring parameters such as voltage, current, and power of the mains terminal 10.

[0105] In other embodiments, the power supply status of the mains terminal 10 can be determined by obtaining other parameters of the mains terminal 10 according to the actual usage.

[0106] Step 140: When the power supply status at the mains power end is abnormal, power is supplied to the power supply system through the backup power supply.

[0107] Thus, by setting up a backup power supply 60 for the power supply system 20, and switching the backup power supply 60 to supply power to the power supply system 20 when the power supply status of the mains power terminal 10 is abnormal, the continuity of power supply is ensured.

[0108] In this embodiment, the power supply method also includes monitoring and switching operations on the power supply status of the mains power terminal 10. Specifically, the power supply method monitors the power supply status of the mains power terminal 10 in real time, such as whether the voltage and frequency of the mains power are within the normal range, and whether there are any abnormal situations such as power outages or severe voltage drops. When an abnormality is detected in the power supply status of the mains power terminal 10, the power supply method immediately triggers control logic to automatically switch the input power of the power supply system 20 from the mains power terminal 10 to a preset backup power supply 60. The backup power supply 60 can be a diesel generator, a large energy storage device, or other forms of emergency power. In this way, during a mains power failure, the backup power supply 60 can seamlessly take over and continuously provide power to the entire power supply system 20, thereby effectively ensuring the continuity of power supply to the back-end loads and avoiding business interruptions caused by mains power outages.

[0109] Please see Figure 8 In some embodiments, the power supply method further includes:

[0110] Step 150: Obtain the voltage and current of the transformer;

[0111] Step 160: When the voltage or current of the transformer is abnormal, power is supplied to the uninterruptible power supply through the battery.

[0112] In this way, by configuring a battery 215 for the uninterruptible power supply 214, and switching the battery 215 to supply power to the uninterruptible power supply 214 when the voltage or current of the transformer 211 is abnormal, the power supply time of the uninterruptible power supply 214 is extended, giving maintenance personnel a window for troubleshooting and reducing the risk of business interruption.

[0113] For example, in this embodiment, the power supply method further includes monitoring the operating parameters of the transformer 211 and backup power supply measures. Specifically, the power supply method continuously acquires the output voltage and current values ​​of the critical transformer 211 (e.g., the transformer 211 supplying power to the uninterruptible power supply 214). Through real-time analysis of these voltage and current values ​​(e.g., determining whether the voltage deviates from the rated range, whether the current is overloaded, or whether there are short-circuit characteristics), any abnormal conditions that may exist in the transformer 211 itself or its input / output circuits can be detected in a timely manner. Once an abnormality in the voltage or current of the transformer 211 is detected, the power supply method immediately activates the backup power supply scheme, controlling the battery 215 group connected to the uninterruptible power supply 214 to start working. The battery 215 group will replace the abnormal transformer 211 and its front-end power supply circuit, directly providing DC power to the uninterruptible power supply 214, enabling its internal inverters and other components to continue operating normally and output AC power. This significantly extends the continuous power supply time of the uninterruptible power supply 214 after front-end problems such as transformer 211 failure occur, providing maintenance personnel with a valuable window for fault diagnosis and handling, and greatly reducing the risk of business interruption due to front-end equipment failure.

[0114] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0115] To facilitate better implementation of the power supply method in the embodiments of this application, the embodiments of this application also provide a power supply device.

[0118] The switching module 220 is configured to, in response to determining an abnormal power supply circuit in the first power supply circuit or the second power supply circuit that is abnormal in power supply according to the operating state, supply power to the device to be powered corresponding to the abnormal power supply circuit through another first power supply circuit or the second power supply circuit that supplies power to the device to be powered corresponding to the abnormal power supply circuit.

[0119] In some embodiments, the acquisition module 210 is further configured to acquire the power supply status of the mains power supply.

[0120] In some embodiments, the switching module 220 is also used to supply power to the power supply system via a backup power source when the power supply status at the mains power supply terminal is abnormal.

[0121] In some embodiments, the acquisition module 210 is further configured to acquire the voltage and current of the transformer.
