Description

Technical Field

[0001] This disclosure relates to the field of power supply technology, and more specifically, to a power supply control method, a power supply control device, an electronic device, and a computer program product. Background Technology

[0002] Data center infrastructure electrical systems have extremely high requirements for power continuity; even a power outage lasting a second can lead to business interruption and significant economic losses. As a core component of the power supply path, a transformer's failure can directly cut off the power supply, and due to its complex structure, repair cycles are typically long, making it difficult to restore power quickly.

[0003] In conventional high-capacity data center electrical architectures, a dual power supply path design is commonly used, with each path supporting switching between municipal power and emergency diesel generators. However, when a transformer in one path fails, both the municipal power and the emergency diesel generators on that path cannot supply power to the data center load, including critical loads such as servers and network equipment, leading to a significant decrease in overall system stability. If the other power supply path also experiences the same failure, it will trigger widespread server and network equipment outages, resulting in a serious production accident. Especially for core network equipment, the impact of the failure may extend to the regional level, causing more widespread business interruptions.

[0004] Therefore, there is an urgent need in the field for a power supply control method that can ensure continuous power supply to the target load when the transformer fails, thereby improving the reliability and continuity of the power supply system.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein.

[0028] The following exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0029] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0030] In some related embodiments, it can be achieved through, for example Figure 1 The power supply architecture shown provides power to the data center load. Municipal power and diesel generator power are led to the transformer through a 10KV bus. The transformer reduces the voltage to 0.4KV before supplying power to the data center load.

[0031] Conventional data centers have large power consumption, with each system ranging from 10,000 KVA to 15,000 KVA (kilovolt-amperes). Due to current limitations, low-voltage diesel generators (0.4 KV) cannot form such a large-capacity parallel system. Therefore, conventional large-capacity data centers typically use multiple 10 KV diesel generators in parallel. However, 10 KV diesel generators cannot directly output emergency power to the low-voltage side of the transformer. In this system, if a transformer failure occurs, the following problems may arise: 1. In this system, the transformer is a critical piece of equipment in the power supply link. Once the transformer fails, the repair cycle is long, the data center load will lose one power source, and the 10KV emergency diesel power supply link in the power supply link will be cut off at the same time. The risk level of power supply to the data center load is greatly increased, the recovery cycle is long, and the stability risk is greatly enhanced.

[0032] 2. If the transformer on the opposite side fails, the data center load will completely lose power, resulting in a large-scale power outage of server equipment and causing business interruption.

[0033] 3. Transformers are mainly composed of iron cores and copper coils, and have virtually no software control. Once a fault occurs, it usually results in extensive hardware damage, which cannot be repaired in a short time, and the fault usually persists for a long period of time.

[0034] To address the aforementioned issues, this exemplary implementation first provides a power supply control method applied to the power supply architecture of a target load. In this architecture, each target load is connected to a basic public power supply and an emergency generator via at least one transformer. (Reference) Figure 2 As shown, the above power supply control method may include the following steps: Step S210. Connect an emergency transformer device between the output terminal of the emergency generator and the output terminals of each transformer. The emergency transformer device includes an emergency transformer.

[0035] Step S220. When the transformer connected to the target load fails, control the faulty transformer to send a start signal to the emergency generator so that the emergency generator can start.

[0036] Step S230. The emergency power generated by the emergency generator is transformed by the emergency transformer and then sent to the output terminal of the fault transformer to supply power to the target load.

[0037] In the power supply control method of this exemplary embodiment, by adding an emergency transformer device between the emergency generator and the transformer output terminal, and automatically triggering the emergency generator to start and switch power when the transformer fails, on the one hand, power supply interruption is effectively avoided, and the emergency power supply can be quickly switched when the transformer fails, ensuring continuous power supply to the target load, improving the reliability and continuity of the power supply system, and avoiding production accidents caused by increased power supply risk level and business interruption; on the other hand, without changing the overall architecture of the original power supply system, the impact of the original system failure on the power supply stability of the target load is solved at a lower cost.

[0038] Next, the steps of this example implementation will be described in more detail.

[0039] In step S210, an emergency transformer device is connected between the output terminal of the emergency generator and the output terminals of each transformer. The emergency transformer device includes an emergency transformer.

[0040] In this example implementation, the emergency transformer is an emergency device used to realize voltage conversion and power transmission. Its main function is to establish a dedicated transmission channel between the emergency power supply and the fault point. The purpose is to bypass the faulty transformer and directly intervene in the power supply architecture, so as to avoid the complete interruption of the power supply path due to a single point of failure.

[0041] In this example implementation, the emergency transformer includes a dummy load. The emergency transformer is connected to the dummy load through the low-voltage emergency bus. In the initial stage of emergency generator startup, the dummy load enables the emergency generator to transition to a stable output state.

[0042] A dummy load is an electrical device used to simulate the characteristics of a real load. It can be implemented using a resistive load, an inductive load, or a combination of both. The purpose of this design is to provide a stable initial load point for the emergency generator, avoiding voltage and frequency fluctuations caused by no-load or light-load conditions. The low-voltage emergency busbar is a connection channel with low impedance characteristics, ensuring a reliable connection between the dummy load and the emergency transformer while achieving physical isolation from the real load. This design aims to ensure the continuity and stability of the emergency power switching process.

[0043] Specifically, when an emergency generator starts, its output voltage and frequency have not yet reached their rated values. Directly connecting it to a real load could lead to malfunctions in data center equipment. Therefore, by connecting a dummy load to the emergency transformer via a low-voltage emergency bus, the dummy load can absorb excess power and simulate real-world load conditions during the initial generator startup phase, allowing the generator to adjust its output under controlled conditions. Once the generator's output voltage and frequency stabilize, the load is then switched to the real target load. This process, based on the dynamic characteristics of the generator from startup to stable operation, effectively avoids the risk of impacting data center equipment due to unstable output, thus achieving rapid and stable emergency power connection.

[0044] In this example implementation, the emergency generator can also be tested by using a dummy load to run under load in order to obtain the test results.

[0045] During emergency generator testing, a dummy load is connected to the generator's output, causing it to operate under load. This process effectively solves the problem that traditional no-load testing cannot comprehensively evaluate generator performance. By using a dummy load, not only can the generator's output characteristics under load conditions be verified, but its stability and reliability at different load levels can also be tested. Furthermore, since the dummy load is a controllable unit independent of the actual load equipment, testing can be completed without relying on a target load, improving testing safety and flexibility. This mechanism ensures the authenticity of test data and provides a reliable basis for subsequent maintenance decisions.

[0046] In step S220, when the transformer connected to the target load fails, the faulty transformer is controlled to send a start signal to the emergency generator so that the emergency generator can start.

[0047] In this example implementation, controlling the faulty transformer to send a start signal to the emergency generator is an automatic triggering mechanism. Its core lies in actively activating the emergency power system based on changes in the state of the fault point. Specifically, this start signal can be generated in various ways, such as using sensors inside the faulty transformer to detect abnormal states and generate a trigger signal, or using external monitoring equipment to monitor the transformer's operating parameters in real time and generate a start command when an anomaly is detected. The aim is to achieve timely activation of the emergency generator, thereby reducing delays caused by manual intervention. When the transformer connected to the target load fails, the faulty transformer is configured to send a start signal to the emergency generator, thereby triggering the automatic start of the emergency generator.

[0048] In this example implementation, an emergency transformer device can be used to detect whether a transformer has malfunctioned. As a key component of the emergency power path, the emergency transformer device is directly connected between the emergency generator and the transformer output. This design allows it to continuously monitor key parameters of the transformer, such as voltage and current. When the device detects an abnormal state where there is no voltage at the transformer output but voltage at the input, it can accurately determine a fault condition. Based on this integrated detection mechanism, the system can quickly respond to fault situations, providing a reliable basis for the subsequent startup of the emergency generator.

[0049] In this example implementation, the operating parameters of the transformer can be detected by an emergency transformer device; if there is no voltage at the output terminal of the transformer and there is voltage at the input terminal of the transformer, the transformer is determined to be a faulty transformer.

[0050] The operating parameters of a transformer can be parameters such as voltage, current, or frequency, which can be used to provide a data foundation for real-time monitoring. Specifically, when a transformer fails, if it can be detected that there is no voltage or current below the faulty transformer, but there is voltage on the transformer input side, then it is determined that the transformer itself is faulty, and the generator is quickly started.

[0051] When a normal voltage is detected at the input, it indicates that the public power supply is normal, ruling out the possibility of upstream power supply issues. Secondly, if there is no voltage at the output, it clearly points to an internal transformer fault. This causal-based judgment logic effectively solves the problem of erroneous emergency generator startup or delayed response caused by misjudgment. Based on this, through continuous monitoring of transformer operating parameters, the system can quickly identify real fault scenarios and trigger emergency responses, ensuring the power supply continuity of critical loads in the data center. Furthermore, this solution, combined with the aforementioned power supply architecture, further enhances the overall system stability and reliability, meeting the critical requirement of second-level power outage protection.

[0052] In step S230, the emergency power generated by the emergency generator is transformed by the emergency transformer and then sent to the output terminal of the fault transformer to supply power to the target load.

[0053] In this example implementation, the emergency power generated after the emergency generator starts will be sent to the emergency transformer. After being transformed by the emergency transformer, it will be adapted to the voltage level required by the target load and directed to the output terminal of the faulty transformer, thereby bypassing the fault point and restoring power supply to the target load.

[0054] Figure 3 A schematic diagram of a data center power supply architecture with an added emergency transformer is shown in one specific embodiment of this disclosure. This emergency transformer consists of an emergency transformer, a low-voltage emergency busbar, and a 0.4kV dummy load.

[0055] refer to Figure 3 As shown, assuming a project uses a power distribution system with an emergency transformer, when transformer 1 experiences a line failure (the failure principle of transformers 2-10 is the same), and data center load 1 loses one power source, the system will perform the following operations: If the emergency transformer detects no voltage on the power output side of transformer 1 while there is voltage on the input side, it indicates a transformer failure. The transformer automatically sends a start signal to the diesel generator. After the generator starts, it outputs 10KV power, which is then transformed by the emergency transformer and automatically provides power to the output side of the faulty transformer 1, thus restoring power to data center load 1. This entire process can also be performed manually.

[0056] In this example implementation, the load rate of each transformer can be determined based on the number of transformers connected to each target load; and the maximum number of faulty transformers that the emergency transformer device can handle simultaneously can be determined based on the load rate of the transformers.

[0057] The number of transformers connected to the target load reflects the degree of redundancy in the power supply architecture, aiming to improve system reliability through multiple power sources. In practical applications, the load factor of a transformer refers to the ratio of the actual load it carries during normal operation to its rated capacity, which can be calculated by monitoring parameters such as the transformer's input and output power and current. The processing capacity of an emergency transformer refers to the number of faulty transformers it can handle simultaneously, which can be dynamically adjusted according to the load factor to ensure the rational allocation of emergency resources. Based on this, the emergency transformer can assess its maximum processing capacity based on the current load factors of all transformers. When multiple transformers fail simultaneously, the system can prioritize powering the target load connected to the transformer with the higher load factor, avoiding power outages to critical equipment due to improper resource allocation.

[0058] For example, the power supply system transformers are in pairs in a 2N system (e.g. Figure 3 Transformers 1 and 10 in the diagram, each normally operates at a load rate of no more than 50%. Therefore, one emergency device can resolve the simultaneous failure of two transformers.

[0059] In this example implementation, if there are two or more faulty transformers in the power supply architecture, the processing priority of the faulty transformer is determined according to the target load connected to the faulty transformer; then, according to the processing priority of the faulty transformer, the emergency transformer is controlled to supply power to the target load connected to the faulty transformer.

[0060] Prioritization can be understood as a mechanism for sorting faulty transformers based on the importance of the target load. This can be achieved through methods such as a pre-set rule base, real-time load monitoring, or manual intervention. Its purpose is to prevent emergency resources from being occupied by low-priority loads, thereby improving overall power restoration efficiency.

[0061] Specifically, when multiple faulty transformers are detected in the power supply architecture, the system first prioritizes them based on the characteristics of the target loads connected to each faulty transformer. For example, core network equipment, due to its high impact range, is assigned a higher priority, while secondary equipment may be assigned a lower priority. Subsequently, based on this priority order, emergency transformers provide emergency power to high-priority target loads sequentially according to predetermined logic. This orderly scheduling mechanism not only effectively prevents low-value loads from occupying limited emergency capacity but also concentrates the output capacity of emergency generators and emergency transformers to minimize the overall service interruption risk. Furthermore, the above scheme, combined with the basic power supply path switching mechanism in multi-fault scenarios, further enhances the flexibility and reliability of the power supply architecture, thereby significantly reducing the possibility of widespread service interruptions caused by multi-point faults.

[0062] Figure 4 A schematic diagram of an emergency transformer device according to a specific embodiment of this disclosure applied to multiple power supply architectures is shown. When a project has multiple identical power supply systems, the device can be expanded in application and is more flexible in its use, allowing for flexible power distribution using multiple 10kV diesel generator systems.

[0063] Large data centers typically have multiple independent power supply systems and multiple 10KV diesel generators. The aforementioned emergency transformer can be extended across different power supply systems and can flexibly draw power from any available 10KV diesel generator system, distributing it to any fault path requiring emergency power. This solution avoids the redundancy of configuring separate emergency devices and diesel generators for each power supply system, improving the sharing and utilization efficiency of emergency resources.

[0064] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result.
