[0020] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to assist understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted below.

[0021] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information involved all comply with the provisions of relevant laws and regulations and do not violate public order and good customs.

[0022] Figure 1 Illustrates an exemplary architecture 100 of a power supply system to which the present disclosure can be applied.

[0023] As Figure 1 shown, the power supply system 100 includes: at least one main power supply subsystem 101, the high-voltage end of each main power supply subsystem is connected to multiple power sources 102, and the low-voltage end is connected to the device to be powered corresponding to the main power supply subsystem; a standby power supply subsystem 103, and the multiple power sources are connected to the low-voltage end of each main power supply subsystem through the standby power supply subsystem.

[0024] Multiple power sources include, for example, at least two of commercial power, power generation equipment, and power storage equipment. The power generation equipment includes, but is not limited to, thermal power generators, wind power generators, hydraulic power generators, nuclear power generators, diesel generators, and solar power generators. The power storage equipment is, for example, a battery, a UPS (Uninterruptible Power Supply), etc.

[0025] The high-voltage end of each primary power supply subsystem obtains high-voltage electrical energy from a power source, converts it into low-voltage electrical energy suitable for the equipment to be powered, and supplies power to the equipment to be powered through the low-voltage end. As an example, the high-voltage end of each primary power supply subsystem is electrically connected to the low-voltage end through a transformer. In Figure 1 there are a total of 5 primary power supply subsystems. Each primary power supply subsystem supplies power to its corresponding equipment to be powered, independently of each other.

[0026] The high-voltage end of the backup power supply subsystem can also obtain high-voltage electrical energy from multiple power sources, convert it into low-voltage electrical energy suitable for the equipment to be powered, and supply power to the equipment to be powered through the low-voltage end. The backup power supply subsystem, as the backup power supply subsystem for all primary power supply subsystems, can be electrically connected to the low-voltage end of each primary power supply subsystem.

[0027] The equipment to be powered can be various equipment that requires power supply, such as cabinets in a data center, refrigeration or heat dissipation equipment, operator equipment, other auxiliary power distribution equipment, etc.

[0028] In this embodiment, the high-voltage end of each primary power supply subsystem in the power supply system is connected to multiple power sources, and the low-voltage end is connected to the equipment to be powered corresponding to the primary power supply subsystem; moreover, the multiple power sources are connected to the low-voltage end of the primary power supply subsystem through the backup power supply subsystem in the power supply system. The power supply system adopts an N+1 architecture, which has a simple structure, reduces the floor area of the power supply equipment. Combining the N+1 architecture and multiple power sources, when an abnormality occurs in a primary power supply subsystem and it cannot supply power, the backup power supply subsystem supplies power to the equipment to be powered corresponding to the abnormal primary power supply subsystem, improving the reliability and power supply efficiency of the power supply system.

[0029] In some optional implementation manners of this embodiment, the multiple power sources 102 include at least one path of commercial power 1021 and a power generation device 1022. The high-voltage end of each primary power supply subsystem and the high-voltage end of the backup power supply subsystem are both connected to at least one path of commercial power; the high-voltage end of each primary power supply subsystem and the high-voltage end of the backup power supply subsystem are connected to their respective corresponding power generation devices.

[0030] Continue to refer to Figure 1, at least one path of mains power 1021 is, for example, two paths of 10KV mains power. In this implementation, the number of paths of mains power is not limited, and the number of paths of mains power can be flexibly set according to actual situations (such as the requirements for power supply reliability). Whether it is the high-voltage end of each primary power supply subsystem or the high-voltage end of the backup power supply subsystem, it is connected to at least one path of mains power.

[0031] The high-voltage end of each primary power supply subsystem and the high-voltage end of the backup power supply subsystem are connected to a respective corresponding power generation device. In this implementation, the power generation device is, for example, a diesel generator.

[0032] In this implementation, various specific composition methods of power sources are provided. By combining at least one path of mains power and power generation devices, the reliability of the power source is improved; the power generation devices adopt a distributed design, eliminating the parallel machine system based on the parallel machine cabinet in the traditional 2N power supply architecture, further simplifying the structure of the power supply system and reducing the equipment cost.

[0033] In some optional implementations of this embodiment, the power supply system further includes: at least one mains power bus 104, and at least one mains power bus corresponds to at least one path of mains power one by one; each path of mains power in at least one path of mains power is connected to the high-voltage end of at least one primary power supply subsystem and the high-voltage end of the backup power supply subsystem through the corresponding mains power bus.

[0034] Continue to refer to Figure 1 , and respective corresponding mains power buses are set for Route A mains power and Route B mains power. Route A mains power is connected to the high-voltage end of at least one primary power supply subsystem and the high-voltage end of the backup power supply subsystem through its corresponding mains power bus; Route B mains power is similarly connected to the high-voltage end of at least one primary power supply subsystem and the high-voltage end of the backup power supply subsystem through its corresponding mains power bus.

[0035] In this implementation, each path of mains power can transmit power to the primary power supply subsystem and the backup power supply subsystem through its corresponding bus, and its beneficial effects are specifically reflected in the following aspects:

[0036] 1. Electric energy collection and distribution:

[0037] The bus can collect the electric energy from the mains power and efficiently and flexibly distribute the electric energy to each primary power supply subsystem and the backup power supply subsystem in case of abnormality according to needs. This collection and distribution function enables the power system to more flexibly meet different power consumption requirements and improves the utilization efficiency of electric energy.

[0038] 2. Simplify the system structure:

[0039] Through the busbar, multiple power supply subsystems (main power supply subsystem and standby power supply subsystem) can be connected together to form a unified power system. This not only simplifies the wiring structure of the system, reduces the complexity of the system, but also reduces the potential failure points caused by complex wiring, thereby improving the stability and reliability of the system.

[0040] 3. Improve system reliability:

[0041] The busbar is usually made of materials with high electrical conductivity and thermal stability, and can withstand large currents and short-circuit currents. Therefore, using the busbar as the medium for power transmission can ensure the stable operation of the power system. In addition, the simple structure and convenient installation of the busbar also reduce the possibility of failures.

[0042] 4. Facilitate expansion and maintenance:

[0043] The busbar system has good expandability, and branches (main power supply subsystem and standby power supply subsystem) can be added or reduced according to needs, which is convenient for the future expansion of the power supply system. At the same time, the modular design of the busbar also makes maintenance and replacement simple and easy. When new electrical equipment needs to be added or the electrical layout needs to be adjusted, only the corresponding expansion or adjustment of the busbar is required.

[0044] 5. Reduce losses:

[0045] The design and optimization of the busbar can reduce the losses during the power transmission process. Through reasonable layout and high transmission efficiency, the busbar can reduce the losses of the power grid and improve the utilization rate of electric energy. This is of great significance for energy conservation, emission reduction and reducing operation costs.

[0046] 6. Improve safety and efficiency:

[0047] In the power system, the busbar is usually used in conjunction with various protection devices (such as circuit breakers, disconnectors, etc.). These protection devices can quickly cut off the fault point when a fault occurs in the system, prevent the fault from expanding, and protect the safety of other equipment and the power grid. At the same time, the use of the busbar also improves the operation efficiency of the power system, enabling electric energy to be transmitted and distributed more efficiently and safely.

[0048] In some optional implementation manners of this embodiment, the power supply system further includes: a high-voltage bus coupler breaker 105, and multiple mains power busbars are connected through the high-voltage bus coupler breaker.

[0049] Specifically, adjacent mains power busbars among multiple mains power busbars are connected through a high-voltage bus coupler breaker. Continuing to refer to Figure 1 , the mains power busbar of the A-phase mains power and the mains power busbar of the B-phase mains power are connected through the high-voltage bus coupler breaker.

[0050] The power supply buses of multiple commercial power supplies are connected by high-voltage circuit breakers, which mainly serve the following functions:

[0051] 1. Load balancing and switching:

[0052] In the power system, if the loads on the dual buses are unbalanced, it will lead to current imbalance, and in severe cases, it will cause voltage drop, affecting the stable operation of the power system. By connecting the power supply buses of two commercial power supplies with a circuit breaker, the balanced distribution of loads between the two buses can be achieved. When the load on one bus is too heavy, part of the load can be switched to the other bus through the circuit breaker, thus maintaining the stable operation of the power system.

[0053] 2. Fault switching and power supply reliability:

[0054] When a fault occurs in one commercial power supply line or bus, in order to ensure continuous power supply to the power system, it is necessary to quickly switch to another normal commercial power supply line or bus. The circuit breaker plays a key role here. It can quickly cut off the faulty circuit after detecting the fault and allow the power system to automatically or manually switch to the standby power supply, thus ensuring continuous power supply to important loads.

[0055] 3. Overload and short-circuit protection:

[0056] The circuit breaker has overload and short-circuit protection functions. When the current in the circuit exceeds the rated current capacity of the circuit breaker, the circuit breaker will automatically trip and cut off the circuit to prevent equipment from being damaged by overload or causing a fire. Similarly, when a short circuit occurs in the circuit, the circuit breaker can also quickly cut off the circuit to protect the safety of the power system and equipment.

[0057] 4. Isolation and maintenance:

[0058] When maintenance or repair of the power system is required, the circuit breaker can be used to isolate specific circuits or bus sections. By cutting off the circuit breaker, it can ensure that maintenance personnel will not come into contact with live parts during work, thus protecting their safety.

[0059] 5. Improving power supply flexibility and expandability:

[0060] By connecting the power supply buses of two commercial power supplies with a circuit breaker, the flexibility and expandability of the power supply system can also be improved. For example, when new loads or power sources need to be added, new equipment can be easily connected to the existing power system through the circuit breaker.

[0061] In some alternative implementation manners of this embodiment, the primary power supply subsystem includes a primary transformer 1011 and a primary circuit breaker 1012; the high-voltage end of the primary power supply subsystem is sequentially connected to the low-voltage end through the primary transformer and the primary circuit breaker.

[0062] Continue to refer toFigure 1 For each primary power supply subsystem, it includes a high-voltage terminal, a primary transformer, a primary circuit breaker, and a low-voltage terminal, and the high-voltage terminal, the primary transformer, the primary circuit breaker, and the low-voltage terminal are connected in sequence.

[0063] In this implementation manner, a composition manner of the primary power supply subsystem is provided, with a simple structure. While realizing the high-low voltage conversion based on the transformer, the flexible control of the primary power supply subsystem is realized based on the primary circuit breaker.

[0064] In some alternative implementation manners of this embodiment, the standby power supply subsystem includes a standby transformer 1031 and at least one standby circuit breaker 1032, and at least one standby circuit breaker corresponds one-to-one to the low-voltage terminal of at least one primary power supply subsystem.

[0065] For each primary power supply subsystem, the high-voltage terminal of the standby power supply subsystem is connected to the low-voltage terminal of the primary power supply subsystem through the standby transformer and the standby circuit breaker corresponding to the low-voltage terminal of the primary power supply subsystem in sequence.

[0066] When the primary power supply subsystem fails to supply power to its corresponding equipment to be powered, the standby power supply subsystem can supply power to the equipment to be powered corresponding to the abnormal primary power supply subsystem.

[0067] In this implementation manner, a composition manner of the standby power supply subsystem is provided, with a simple structure. While realizing the high-low voltage conversion based on the transformer, based on multiple standby circuit breakers, one standby power supply subsystem is used as the standby system for all primary power supply subsystems, further simplifying the structure and improving the reliability of the power supply system.

[0068] In some alternative implementation manners of this embodiment, the low-voltage terminal includes a primary bus 106 and a standby bus 107; the primary circuit breaker is connected to the primary bus, and the standby circuit breaker is connected to the standby bus.

[0069] In this implementation manner, the two buses at the low-voltage terminal are respectively connected to the primary power supply subsystem and the standby power supply subsystem.

[0070] In this implementation manner, using the bus to supply power to the equipment to be powered is similar to the above-mentioned method of supplying power through the information high-voltage terminal of the city power bus, and there are many benefits in aspects such as power energy collection and distribution, simplifying the system structure, improving the system reliability, expansion and maintenance, reducing losses, and improving safety and efficiency.

[0071] In some alternative implementation manners of this embodiment, the low-voltage terminal further includes a low-voltage bus tie breaker 108, and the primary bus and the standby bus are connected through the low-voltage bus tie breaker.

[0072] The main bus and the standby bus in the low-voltage end of each primary power supply subsystem are connected by a low-voltage bus-tie breaker.

[0073] In this implementation, in the low-voltage end of each primary power supply subsystem, the corresponding bus segments of the primary power supply subsystem and the standby power supply subsystem are connected by a low-voltage bus-tie breaker. Similar to the high-voltage bus-tie breaker in the above implementation, there are many benefits in terms of load balancing and switching, fault switching and power supply reliability, overload and short-circuit protection, isolation and maintenance, and improving power supply flexibility and expandability.

[0074] Continue to refer to Figure 2 , which shows an exemplary architecture 200 to which the power supply method and apparatus of the present disclosure can be applied.

[0075] As Figure 2 shown, the system architecture 200 may include terminal devices 201, 202, 203, a network 204, and a server 205. The terminal devices 201, 202, 203 are communicatively connected to form a topology network, and the network 204 is used to provide a medium for communication links between the terminal devices 201, 202, 203 and the server 205. The network 204 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0076] The terminal devices 201, 202, 203 may be hardware devices or software that support network connections for data interaction and data processing. When the terminal devices 201, 202, 203 are hardware, they may be various electronic devices that support network connections, information acquisition, interaction, display, processing, etc., including but not limited to various circuit breakers such as high-voltage bus-tie breakers, low-voltage bus-tie breakers, primary circuit breakers, and standby circuit breakers in the power supply system, various remotely controllable devices such as transformers and power generation equipment, and status detection devices for detecting the operating status of each primary power supply subsystem in the power supply system. When the terminal devices 201, 202, 203 are software, they may be installed in the above-listed electronic devices. It may be implemented as, for example, multiple software or software modules for providing distributed services, or may be implemented as a single software or software module. No specific limitation is made here.

[0077] The server 205 may be a server that provides various services. For example, when an abnormal primary power supply subsystem is determined from the operating status of at least one primary power supply subsystem in the power supply system, a background processing server that supplies power to the power supply equipment corresponding to the abnormal primary power supply subsystem through the standby power supply subsystem in the power supply system by controlling the opening and closing states of the terminal devices 201, 202, 203. As an example, the server 205 may be a cloud server.

[0078] It should be noted that the server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster composed of multiple servers, or as a single server. When the server is software, it can be implemented as multiple software or software modules (such as software or software modules for providing distributed services), or as a single software or software module. Specific limitations are not made here.

[0079] It should also be noted that the power supply method provided by the embodiments of the present disclosure is generally executed by the server, but the possibility of being executed by the terminal device or by the server and the terminal device cooperating with each other is not excluded. Correspondingly, each part (such as each unit) included in the power supply device can be all arranged in the server, or all arranged in the terminal device, or can be respectively arranged in the server and the terminal device.

[0080] It should be understood that Figure 2 the numbers of the terminal devices, the network, and the servers in

[0081] are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, networks, and servers. When the electronic device on which the power supply method runs does not need to perform data transmission with other electronic devices, the system architecture can only include the electronic device (such as a terminal device or a server) on which the power supply method runs. Figure 3 , Figure 3 Please refer to

[0082] FIG.

[0083] In this embodiment, the execution subject of the power supply method (for example, the server in Figure 1 ) can determine the operating state of at least one primary power supply subsystem in the power supply system through a wired network connection or a wireless network connection, either remotely or locally. Among them, the high-voltage end of each primary power supply subsystem is connected to multiple power sources, and the low-voltage end is connected to the power supply device corresponding to the primary power supply subsystem.

[0084] As an example, the above-mentioned execution subject can obtain the operating state of each primary power supply subsystem based on the state monitoring device of each primary power supply subsystem, and analyze whether each primary power supply subsystem is abnormal according to the operating state, that is, whether it can safely supply power to its corresponding power supply device.

[0085] As another example, the above-mentioned execution entity can obtain the operating status of each primary power supply subsystem based on the maintenance personnel of the power supply system, and analyze whether each primary power supply subsystem is abnormal according to the operating status. The maintenance personnel of the power supply system can regularly detect the power supply system to report the operating status of each primary power supply subsystem to the above-mentioned execution entity.

[0086] Step 302, in response to determining an abnormal primary power supply subsystem from at least one primary power supply subsystem according to the operating status, supply power to the power supply device to be powered corresponding to the abnormal primary power supply subsystem through the standby power supply subsystem in the power supply system.

[0087] In this embodiment, the above-mentioned execution entity can, in response to determining an abnormal primary power supply subsystem from at least one primary power supply subsystem according to the operating status, supply power to the power supply device to be powered corresponding to the abnormal primary power supply subsystem through the standby power supply subsystem in the power supply system. Among them, multiple power sources are connected to the low-voltage ends of each primary power supply subsystem through the standby power supply subsystem.

[0088] Specifically, the above-mentioned execution entity can turn off the abnormal primary power supply subsystem and turn on the standby power supply subsystem to supply power to the power supply device to be powered corresponding to the abnormal primary power supply subsystem.

[0089] In some optional implementation manners of this embodiment, the above-mentioned execution entity can also determine the maximum number through any of the following operations:

[0090] Operation 1: Determine the maximum number of primary power supply subsystems that the standby power supply subsystem can simultaneously replace according to the load data of each primary power supply subsystem in at least one primary power supply subsystem.

[0091] As an example, after the load data of each primary power supply subsystem in at least one primary power supply subsystem and the maximum load data that the standby power supply subsystem can bear, the number of primary power supply subsystems whose sum of load data does not exceed the maximum load data and is closest to the maximum load data is used as the maximum number.

[0092] Operation 2: Determine the maximum number according to the received configuration operation.

[0093] As an example, the above-mentioned execution entity can provide a user interface for the user to perform a configuration operation, and the user inputs the value corresponding to the maximum number in the user interface.

[0094] In this implementation manner, the above-mentioned execution entity can execute the above step 302 in the following way: in response to determining multiple abnormal primary power supply subsystems from at least one primary power supply subsystem according to the operating status, and the number of abnormal primary power supply subsystems is less than or equal to the maximum number, the standby power supply subsystem supplies power to the power-consuming devices corresponding to each of the multiple abnormal primary power supply subsystems.

[0095] When the number of abnormal primary power supply subsystems is less than or equal to the maximum number, the standby power supply subsystem can undertake the power supply tasks corresponding to the multiple abnormal primary power supply subsystems. At this time, a standby power supply subsystem can supply power to the power-consuming devices corresponding to each of the multiple abnormal primary power supply subsystems.

[0096] In this implementation manner, based on the maximum number, the standby power supply subsystem supplies power to the power-consuming devices corresponding to each of the multiple abnormal primary power supply subsystems, further improving the reliability of the power supply system.

[0097] Continue to refer to Figure 1 , in some alternative implementation manners of this embodiment, the primary power supply subsystem includes a primary transformer and a primary circuit breaker, the standby power supply subsystem includes a standby transformer and at least one standby circuit breaker, at least one standby circuit breaker corresponds one-to-one to the low-voltage end of at least one primary power supply subsystem, the low-voltage end includes a primary bus, a standby bus, and a low-voltage bus tie breaker, the primary bus and the standby bus in each low-voltage end are connected by the low-voltage bus tie breaker, for each primary power supply subsystem, the high-voltage end of the primary power supply subsystem is sequentially connected to the primary bus through the primary transformer and the primary circuit breaker, and the high-voltage end of the standby power supply subsystem is sequentially connected to the standby bus of the low-voltage end of the primary power supply subsystem through the standby transformer and the standby circuit breaker corresponding to the low-voltage end of the primary power supply subsystem.

[0098] In this implementation manner, the above-mentioned execution entity can perform the power supply operation in the following way: disconnect the primary circuit breakers corresponding to each of the multiple abnormal primary power supply subsystems, and close the standby circuit breakers and the low-voltage bus tie breakers corresponding to each of the multiple abnormal primary power supply subsystems, so as to supply power to the power-consuming devices corresponding to each of the multiple abnormal primary power supply subsystems through the standby power supply subsystem.

[0099] When each primary power supply subsystem is supplying power normally, the primary circuit breaker and the low-voltage bus tie breaker in each primary power supply subsystem are closed, and the standby circuit breaker corresponding to the standby power supply subsystem is opened; when multiple primary power supply subsystems are abnormal, open the primary circuit breakers corresponding to each of the multiple abnormal primary power supply subsystems, and close the standby circuit breakers and the low-voltage bus tie breakers corresponding to each of the multiple abnormal primary power supply subsystems, so as to supply power to the power-consuming devices corresponding to each of the multiple abnormal primary power supply subsystems through the standby power supply subsystem.

[0100] In this implementation manner, based on various circuit breakers, the backup power supply subsystem can be conveniently used for power supply, and power can be supplied to the devices to be powered corresponding to multiple abnormal main power supply subsystems respectively, further improving the operation convenience and reliability of the power supply system.

[0101] In some alternative implementation manners of this embodiment, the above-mentioned execution entity can also execute the above step 302 in the following manner:

[0102] First step, in response to determining multiple abnormal main power supply subsystems from at least one main power supply subsystem according to the operating state, and the number of abnormal main power supply subsystems is greater than the maximum number, determine the maximum number of target main power supply subsystems from the multiple abnormal main power supply subsystems.

[0103] As an example, the above-mentioned execution entity can determine the maximum number of target main power supply subsystems from the multiple abnormal main power supply subsystems based on the following considerations:

[0104] I. Importance and priority of the devices to be powered

[0105] Priority for critical devices: First, ensure that the devices crucial for production, operation, or safety are powered. These devices are usually the core links in the production process or the devices that have a direct impact on personal safety.

[0106] Business continuity requirements: Consider the impact of the devices on business continuity. For the devices that need to run continuously to maintain normal business operation, priority should be given to power supply.

[0107] II. Energy consumption and efficiency of the devices

[0108] Energy efficiency ratio: Select the devices with a high energy efficiency ratio for power supply to reduce energy consumption and save resources. The energy efficiency ratio usually refers to the ratio of the output power to the input power of the device, and the higher the ratio, the better the energy efficiency.

[0109] No-load loss and short-circuit loss: For devices such as transformers, their no-load loss and short-circuit loss should be considered. The devices with low losses can make better use of electric energy during power supply and reduce energy waste.

[0113] IV. Compatibility and scalability of the devices

[0114] Compatibility: Select devices with strong compatibility to ensure that they can work with other devices and meet different power supply requirements.

[0131] Wherein, the high-voltage end of each main power supply subsystem is connected to multiple power sources, and the low-voltage end is connected to the device to be powered corresponding to the main power supply subsystem.

[0132] Step 503, in response to determining multiple abnormal main power supply subsystems from at least one main power supply subsystem according to the operating state, and the number of abnormal main power supply subsystems is less than or equal to the maximum number, supply power to the devices to be powered corresponding to the multiple abnormal main power supply subsystems through the standby power supply subsystem.
