Description

Technical Field

[0001] This application relates to the field of generator set configuration technology, and more specifically, to a method for configuring redundant generator sets and a diesel generator system. Background Technology

[0002] Data centers are energy-intensive, and each server room requires not only a safe and reliable mains power supply with multiple backup power lines, but also multiple or even dozens of high-voltage, high-power diesel generator sets as emergency power sources. In the event of a power outage, these generators can automatically start and operate in parallel to supply power to the numerous servers and cooling systems in the data center.

[0003] To ensure the safe and reliable emergency power supply of diesel generator sets, data centers or core hub communication base stations will configure multiple high-power generator sets according to the power capacity of their server rooms and the power capacity of their supporting cooling systems, as well as their importance. These high-power generator sets will be connected in parallel to provide backup emergency power for the data center server rooms. This results in a complex wiring situation, which leads to higher costs. The current solution is to configure a redundant generator set for each diesel generator set as an emergency power supply, which also results in complex wiring and higher costs. Summary of the Invention

[0004] The main objective of this application is to provide a method for configuring redundant generator sets and a diesel power generation system, so as to at least solve the problem that the existing scheme of configuring a redundant generator set for each diesel generator set as an emergency power source results in complex wiring and high costs.

[0005] To achieve the above objectives, according to one aspect of this application, a method for configuring redundant generator sets is provided, applied in a controller of redundant generator sets in a power generation system. The power generation system further includes multiple sets of diesel generator sets, each set comprising multiple diesel generators. The redundant generator sets communicate with all of the diesel generator sets. The method includes: acquiring the status of each diesel generator set; and, when all diesel generator sets are in a state of either power failure or power supply, the redundant generator sets, according to their priorities, connect one set of diesel generator sets in parallel to supply power to a power distribution system. The priority order is determined based on the importance of each diesel generator set in supplying power to the load.

[0006] Optionally, the multiple diesel generator sets are respectively a first diesel generator set and a second diesel generator set; obtaining the status of each diesel generator set includes: obtaining the status of the first diesel generator set and the status of the second diesel generator set, respectively obtaining the status of the first generator set and the status of the second generator set;

[0007] The redundant generator set operates in parallel with one of the diesel generator sets according to the priority of each diesel generator set to supply power to the power distribution system. This includes: the redundant generator set supplies power to the first diesel generator set or the second diesel generator set according to a first priority and a second priority, wherein the first priority is the priority of the first diesel generator set, the second priority is the priority of the second diesel generator set, and the first priority and the second priority are of different levels.

[0008] Optionally, after obtaining the status of the first generator set and the status of the second generator set, the method further includes: when the first generator set is in a power-off state and the second generator set is in a power-on state, the redundant generator set supplies power to the first diesel generator set; when the first generator set is in a power-on state and the second generator set is in a power-off state, the redundant generator set supplies power to the second diesel generator set.

[0009] Optionally, during the process of supplying power to the first diesel generator set or the second diesel generator set according to a first priority and a second priority, the method further includes: the redundant generator set receiving and responding to a first preset operation acting on the touch screen controller to supply power to the first diesel generator set, and the touch screen controller communicating with the redundant generator set; the redundant generator set receiving and responding to a second preset operation acting on the touch screen controller to control the redundant generator set to supply power to the second diesel generator set.

[0010] Optionally, before obtaining the status of each of the diesel generator sets, the method further includes: the redundant generator set predicting a target faulty generator set based on historical parameter data and a time series prediction algorithm for each of the diesel generator sets, the target faulty generator set representing the diesel generator set most prone to failure among all the diesel generator sets; performing a preheating treatment on the redundant generator set, the preheating treatment including preheating the coolant and engine oil of the redundant generator set to reduce mechanical wear during startup of the redundant generator set.

[0011] Optionally, the method further includes: acquiring environmental information, including the temperature, humidity, grid load, and health status of the environment in which the redundant generator sets are located; and adjusting the priority of at least some of the redundant generator sets based on the environmental information.

[0012] Optionally, supplying power to the first diesel generator set includes: obtaining a power mapping relationship, wherein the power mapping relationship is the relationship between priority and power supply; determining a target power supply based on the power mapping relationship and the first priority; and the redundant generator set using the target power supply to supply power to the first diesel generator set.

[0013] Optionally, the redundant generator set supplies power to the first diesel generator set by: switching the position of the switching switch from a first position to a second position to connect the redundant generator set and the first diesel generator set, so that the redundant generator set supplies power to the first diesel generator set. The position of the switching switch includes the first position, the second position, and the third position, and the switching switch is electrically connected to the redundant generator set, the first diesel generator set, and the second diesel generator set, respectively.

[0014] The redundant generator set supplies power to the second diesel generator set by: switching the position of the switching switch from the first position to the third position to connect the redundant generator set and the second diesel generator set, so that the redundant generator set supplies power to the second diesel generator set.

[0015] According to another aspect of this application, a diesel generator system is provided, comprising: multiple sets of diesel generator sets and a set of redundant generator sets, the generator system further comprising multiple sets of diesel generator sets, the redundant generator set communicating with each of the diesel generator sets, the redundant generator set being used to perform any of the methods described.

[0016] Optionally, the diesel generator system further includes a touch screen controller and a switching switch, wherein the switching switch is electrically connected to the redundant generator set and each of the diesel generator sets, and the touch screen controller communicates with the redundant generator sets.

[0017] By applying the technical solution of this application, a unified communication interface is established between redundant generator sets and all diesel generator sets, enabling real-time acquisition of the status information of each group of diesel generator sets, including but not limited to power grid outages, unit operating status, and fault conditions. This improvement simplifies the system architecture by reducing the number of independent communication links, making the control logic and hardware configuration more centralized and unified, thereby reducing overall cost and complexity. Priority settings are based on the importance and urgency of the loads served by each group of diesel generator sets, ensuring that the most important group receives priority power supply in the event of a power outage. Compared with traditional fixed redundancy configurations, dynamic priority decision-making can more efficiently utilize the power output of redundant generator sets, avoiding resource waste, especially when power demand fluctuates greatly or the urgency of different groups' loads changes, providing greater flexibility and response speed. Using the method of this application, only one or a few redundant generator sets are needed to cover all groups. Through intelligent switching and priority control, any group can be connected in parallel in emergencies to supply power to the distribution system. This configuration significantly reduces the total number of generator sets and auxiliary facilities required, thereby significantly reducing construction and operating costs. This solves the problem of the existing solution, which requires each diesel generator set to be equipped with a redundant generator set as an emergency power source, resulting in complex wiring and high costs.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0030] As described in the background section, to ensure the safe and reliable emergency power supply of diesel generator sets, data centers or core hub communication base stations will configure multiple high-power generator sets according to the power capacity of each server room and the power capacity of the supporting cooling system, as well as their importance. These high-power generator sets will be connected in parallel to provide backup emergency power for the data center server rooms, resulting in complex wiring and high costs. To solve the problem of the existing solution of configuring a redundant generator set for each diesel generator set as an emergency power supply, which results in complex wiring and high costs, the embodiments of this application provide a method for configuring redundant generator sets and a diesel power generation system.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] This embodiment provides a method for configuring redundant generator sets. The method is applied to the controller of the redundant generator sets in a power generation system. The power generation system further includes multiple sets of diesel generator sets, each set of which includes multiple diesel generators. The redundant generator sets communicate with all of the aforementioned diesel generator sets. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 1 This is a flowchart of a method for configuring redundant generator sets according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:

[0034] Step S101: Obtain the status of each of the aforementioned diesel generator sets;

[0035] In step S102, when all the aforementioned diesel generator sets are either de-energized or energized, the redundant generator sets are connected in parallel to one of the aforementioned diesel generator sets according to their respective priorities, in order to supply power to the power distribution system. The order of these priorities is determined based on the importance of each of the aforementioned diesel generator sets in supplying power to the load.

[0036] In existing solutions, each diesel generator set has its own redundant generator set, meaning there are multiple independent communication links in the system, each requiring separate hardware and software support, which undoubtedly increases system complexity and cost. In this application, a unified communication interface is established between the redundant generator sets and all diesel generator sets, enabling real-time acquisition of the status information of each set, including but not limited to grid outages, generator operating status, and fault conditions. This improvement simplifies the system architecture by reducing the number of independent communication links, making the control logic and hardware configuration more centralized and unified, thereby reducing overall cost and complexity. The redundant generator sets in this application can intelligently select which set of diesel generator sets to supply power to, based on a preset priority order, in the event of a power outage or power supply failure of all other diesel generator sets. The priority setting is based on the importance and urgency of the load served by each set of diesel generator sets, ensuring that the most important set receives power first in the event of a power outage. Compared to traditional fixed redundancy configurations, dynamic priority decision-making can more efficiently utilize the power output of redundant generator sets, avoiding resource waste, especially when power demand fluctuates greatly or the urgency of different sets of loads changes, providing greater flexibility and response speed. In existing solutions, a redundant generator set is required for each diesel generator set to ensure emergency power supply. This not only leads to a surge in the number of devices but also results in high costs due to the need for separate infrastructure (such as fuel storage, cooling systems, and noise reduction facilities). However, the method of this invention requires only one or a few redundant generator sets to cover all sets. Through intelligent switching and priority control, any set can be connected in parallel in emergencies to supply power to the power distribution system. This configuration significantly reduces the total number of generator sets and ancillary facilities required, thereby significantly reducing construction and operating costs. Furthermore, it solves the problem of existing solutions that require a separate redundant generator set for each diesel generator set as an emergency power source, resulting in complex wiring and high costs.

[0037] In one embodiment of this application, the aforementioned multiple diesel generator sets are respectively a first diesel generator set and a second diesel generator set; obtaining the status of each diesel generator set includes: obtaining the status of the first diesel generator set and the status of the second diesel generator set, respectively obtaining the status of the first generator set and the status of the second generator set;

[0038] The aforementioned redundant generator sets operate in parallel with one of the aforementioned diesel generator sets according to the priority of each of the aforementioned diesel generator sets to supply power to the power distribution system, including: the aforementioned redundant generator sets supply power to the aforementioned first diesel generator set or the aforementioned second diesel generator set according to a first priority and a second priority, wherein the aforementioned first priority is the priority of the aforementioned first diesel generator set, the aforementioned second priority is the priority of the aforementioned second diesel generator set, and the aforementioned first priority and the aforementioned second priority are of different levels.

[0039] Specifically, by setting different priorities, redundant generator sets can more intelligently allocate their power resources. In the event of a power outage, redundant generator sets will prioritize powering diesel generator sets with higher priority (i.e., more important systems or loads). This ensures the normal operation of critical systems even under resource constraints, significantly improving the overall reliability and efficiency of the system. Traditional methods require a redundant generator set for each diesel generator set, leading to a substantial increase in equipment and maintenance costs. The method of this invention requires only one redundant generator set to provide emergency power support for multiple diesel generator sets, significantly reducing equipment investment and operation and maintenance costs. A unified communication mechanism is established between the redundant generator set and all diesel generator sets, which not only reduces the complexity of communication lines but also lowers the failure rate that may be caused by too many lines, making the entire power generation system architecture simpler and more stable. When all diesel generator sets are out of power, the redundant generator set can quickly start supplying power according to priority order without human intervention, greatly shortening the time from power outage to power restoration and improving the system's emergency response speed.

[0040] In one embodiment of this application, after obtaining the first unit state and the second unit state respectively, the method further includes: when the first unit state is de-energized and the second unit state is energized, the redundant generator set supplies power to the first diesel generator set; when the first unit state is energized and the second unit state is de-energized, the redundant generator set supplies power to the second diesel generator set.

[0041] Specifically, it can quickly respond to the power outage of a single generator unit without waiting for all units to lose power before activating redundant generator sets. Once a power supply problem is detected in any unit, redundant generator sets immediately intervene to provide power support, significantly shortening emergency response time and reducing the possibility of service interruptions. By precisely locating the failed generator unit and supplying power only to it, the impact of power outages can be limited to a small area. This means that even if one unit fails, the remaining units and their service loads can still operate normally, thus ensuring that the overall operation of critical facilities such as data centers and communication base stations is not significantly disrupted. When a group of diesel generator sets is operating normally, redundant generator sets will not start blindly, avoiding unnecessary energy waste and startup costs. This method ensures that the startup and operation of redundant generator sets are based on actual demand, improving energy utilization efficiency. Even in the event of a partial power outage, the system can maintain operation through the timely intervention of redundant generator sets. This method enhances the overall reliability of the system, especially under high load or emergency conditions, providing stable power support and reducing the system failure rate caused by unstable power supply.

[0042] In one embodiment of this application, during the process of supplying power to the first diesel generator set or the second diesel generator set according to a first priority and a second priority, the method further includes: the redundant generator set receiving and responding to a first preset operation acting on the touch screen controller to supply power to the first diesel generator set, and the touch screen controller communicating with the redundant generator set; the redundant generator set receiving and responding to a second preset operation acting on the touch screen controller to control the redundant generator set to supply power to the second diesel generator set.

[0043] Specifically, the introduction of touchscreen controllers greatly facilitates the control of redundant generator sets by operators. Through an intuitive user interface, operators can quickly make decisions and execute corresponding power supply operations without complex physical switching or cumbersome manual operations, improving operational convenience and efficiency. Preset operations performed by operators via the touchscreen controller can be responded to by the redundant generator sets in real time. This means that in emergencies, redundant generator sets can be quickly started to supply power to the required diesel generator sets, shortening the delay time from decision to execution and enhancing the system's real-time responsiveness. Controlled through the touchscreen controller, operators can more flexibly adjust the power supply targets of the redundant generator sets based on current power demand, system status, and priority information. This enhanced controllability not only improves operational accuracy but also enables the system to maintain stability and efficiency in complex and changing environments. Touchscreen controllers typically have input verification functions to prevent operator errors. When controlling redundant generator sets to supply power to the first or second diesel generator set, the system can use the confirmation function of the touchscreen controller to ensure that operations are only performed under safe and operational conditions, thereby reducing operational risks and improving the safety of the entire power generation system.

[0044] In one embodiment of this application, before obtaining the status of each of the aforementioned diesel generator sets, the method further includes: the redundant generator sets predicting target faulty generator sets based on historical parameter data and time series prediction algorithms for each of the aforementioned diesel generator sets, wherein the target faulty generator sets represent the diesel generator sets that are prone to failure among all the aforementioned diesel generator sets; and performing a preheating treatment on the redundant generator sets, wherein the preheating treatment includes preheating the coolant and engine oil of the redundant generator sets to reduce mechanical wear during startup of the redundant generator sets.

[0045] Specifically, this application also provides a specific use case for performing preheating treatment of redundant generator sets: In large data centers, a stable power supply is crucial to ensuring the uninterrupted operation of servers and supporting facilities. In this scenario, diesel generator sets serve as backup power sources and must be ready to take over power supply tasks in the event of a failure of the main power supply. Considering the varying operating conditions and potential failure risks of different diesel generator sets, using time series prediction algorithms to analyze historical parameter data, such as operating time, maintenance records, ambient temperature, and fuel consumption rate, to predict which units are likely to fail in the near future—that is, identifying target faulty units—is a key measure to improve the overall reliability of the system.

[0046] Implementation Steps: The data center maintenance team regularly collects and summarizes the operating data of all diesel generator sets, including but not limited to parameters such as operating time, ambient temperature, fuel consumption rate, coolant temperature, and oil pressure. This data is then input into time series prediction algorithms, such as ARIMA models and Long Short-Term Memory (LSTM) networks, to predict the failure probability of each unit. This step fully utilizes the value of historical data, enabling more accurate identification of potential failure risk sources. Through algorithmic analysis, units with a high failure probability are marked as target failure-prone units. This prediction provides early warnings, offering decision-making support to the maintenance and management team to optimize emergency preparedness. Once a diesel generator set (e.g., the first diesel generator set) is predicted to be a target failure-prone unit, the system automatically or manually initiates a preheating process for the redundant generator set. The preheating process includes heating the coolant and oil to ensure that the redundant generator set can start quickly when needed, without affecting its performance due to mechanical wear caused by low temperatures.

[0047] The beneficial effects of preheating redundant generator sets in a specific use case include: Preheating ensures that redundant generator sets can start quickly when necessary, reducing start-up delays, which is especially critical for locations with extremely high power continuity requirements, such as data centers; through prediction and preheating, downtime caused by generator start-up problems can be effectively reduced, improving overall system availability. Early prediction of target fault-prone units helps maintenance teams schedule preventative maintenance and resource allocation more efficiently, avoiding emergency repairs due to sudden failures, thereby reducing maintenance costs; preheating reduces mechanical wear during startup, helping to extend the lifespan of generator sets, reducing the frequency of equipment replacement, and further saving costs; overall, this prediction-based preheating mechanism significantly improves the reliability of backup power systems, providing data centers with a safer and more stable power guarantee. Combined with touchscreen controllers and time-series prediction algorithms, operators can more easily monitor and control generator sets, while the system's intelligence level is improved, reducing the complexity and potential errors of human operation.

[0048] In one embodiment of this application, such as Figure 2 As shown, the above method also includes:

[0049] Step S201: Obtain environmental information, including the temperature, humidity, grid load, and health status of the redundant generator set in the environment.

[0050] Step S202: Adjust the priority of at least some of the redundant generator sets based on the above environmental information.

[0051] Specifically, this application provides a particular use case for adjusting the priority of at least some of all redundant generator sets: In situations involving extreme weather conditions, such as extreme cold, hot and humid environments, or large-scale fluctuations in power demand, the power supply of critical facilities like data centers and communication base stations faces severe challenges. In this scenario, adjusting the priority of redundant generator sets based on environmental information ensures that, in emergencies, the most suitable generator set can respond quickly and provide stable power to the system.

[0052] Implementation Steps: The controller of the redundant generator sets continuously monitors various parameters of their environment, including ambient temperature, humidity, grid load, and their own health status. For example, in cold winter conditions, generator start-up may be affected; in hot summer conditions, reduced cooling system efficiency may lead to overheating. Real-time changes in grid load reflect the intensity of the system's power demand, while the health status of the generator sets directly affects their effective start-up and operation. Based on the acquired environmental information, the controller uses intelligent algorithms (such as machine learning and fuzzy logic systems) to analyze the potential impact of each parameter on generator set performance and adjusts the priority of redundant generator sets accordingly. For example, generator sets with temperatures below a certain threshold may have their priority reduced to avoid potential problems during cold starts; conversely, generator sets with moderate temperatures and good health have their priority increased, becoming the preferred emergency power source. In the event of a grid failure or a sudden increase in power demand, the system, based on the adjusted priority order, quickly starts and puts into operation the most suitable redundant generator set. This intelligent decision-making based on real-time environmental information ensures optimal generator set performance and the shortest response time.

[0053] The beneficial effects of adjusting the priority of at least some of all redundant generator sets in a specific use case include: prioritizing the generator sets with the best health and environmental adaptability to restore power supply in the shortest time and reduce service interruption time; by monitoring grid load and their own health, redundant generator sets can avoid starting under adverse conditions, reducing the risk of equipment damage and extending the life of the generator sets; reducing maintenance costs: intelligent priority adjustment ensures that generator sets operate under optimal conditions, reducing wear and tear caused by frequent starts and reducing maintenance and repair costs; priority adjustment based on environmental information ensures stable operation of generator sets under various environmental conditions, improving the reliability and stability of the entire emergency power supply system. By considering environmental factors, the system can more intelligently allocate the starting order of redundant generator sets, avoiding resource waste and achieving more efficient energy management; whether in extreme weather conditions or in scenarios with drastic fluctuations in grid demand, the system can respond flexibly, maximizing the effectiveness and security of power supply by dynamically adjusting priorities.

[0054] In one embodiment of this application, such as Figure 3 As shown, supplying power to the first diesel generator set includes the following steps:

[0055] Step S301: Obtain the power mapping relationship, which is the relationship between priority and power supply.

[0056] Step S302: Determine the target power supply based on the power mapping relationship and the first priority mentioned above;

[0057] In step S303, the redundant generator set supplies power to the first diesel generator set using the target power supply.

[0058] Specifically, the second diesel generator set operates similarly, and will not be elaborated further here. Through dynamic adjustment of the power mapping relationship, the redundant generator set can provide precise power supply according to the actual needs of the first diesel generator set, avoiding situations of power surplus or shortage and achieving efficient utilization of power resources. When the system detects an increase in the priority of the first diesel generator set, the redundant generator set can quickly adjust its power supply to respond rapidly to changes in power demand, especially in emergencies, providing timely power support for critical operations. By ensuring that the power supply matches the priority, operational instability or safety issues caused by generator set overload or underload are avoided, improving the stability and safety of the entire system operation.

[0059] In one embodiment of this application, the redundant generator set supplies power to the first diesel generator set, including: switching the position of the switching switch from a first position to a second position to connect the redundant generator set and the first diesel generator set, so that the redundant generator set supplies power to the first diesel generator set. The position of the switching switch includes the first position, the second position, and the third position. The switching switch is electrically connected to the redundant generator set, the first diesel generator set, and the second diesel generator set, respectively.

[0060] The redundant generator set supplies power to the second diesel generator set by: switching the position of the switching switch from the first position to the third position to connect the redundant generator set and the second diesel generator set, so that the redundant generator set supplies power to the second diesel generator set.

[0061] Specifically, when the second diesel generator set fails or the power grid is interrupted, a quick switchover allows the redundant generator set to rapidly connect and begin supplying power. This not only quickly restores power to the service area of ​​the second diesel generator set but also isolates the fault, preventing the failed unit from affecting the stable operation of the entire system. Switching to the third position is typically very rapid, significantly reducing the power outage time in the service area of ​​the second diesel generator set. This is crucial for ensuring the continuous operation of critical facilities such as data centers and communication base stations, effectively avoiding business losses and data security risks caused by prolonged power outages. Traditional redundancy mechanisms may require an independent redundant generator set for each diesel generator set. However, through a flexible switchover design, a single redundant generator set can switch between different positions (first position, third position, etc.), providing redundancy support for multiple diesel generator sets, enhancing the overall redundancy of the system, and reducing equipment investment and space occupation. The dynamic allocation of redundant generator sets ensures maximum resource utilization. Under normal operating conditions, redundant generator sets are in standby mode, reducing unnecessary energy consumption and equipment wear. In the event of a fault, the power supply needs of the failed generator set can be quickly located and met, avoiding the waste of redundant resources.

[0062] like Figure 4 As shown, the diesel generator system includes: a first diesel generator set 100, a second diesel generator set 200, a redundant generator set 300, a switch 400, and a touch screen controller 500.

Unit G6 is a redundant, swing-parallel unit. The primary system connects to the Group A bus via the Group A bus and the Group B bus via the interlocking switch cabinets CH01 / CH02, and then to the Group A bus via the redundant unit's incoming line parallel cabinet AH07; it also connects to the Group B bus via the redundant unit's incoming line parallel cabinet BH07. CH01 / CH02 have electrical and mechanical interlocking functions; if CH01 is closed, CH02 cannot be closed, and vice versa. For successful synchronous parallel operation between high-voltage, high-power diesel generator sets, the units should be able to communicate during parallel operation, use a common busbar, employ the same busbar T signal, and the differential current protection signal should also be correspondingly closed. To enable the redundant units to operate in parallel with either the busbar of Group A or the busbar of Group B, the AC06 control panel of the redundant units automatically acquires the incoming PT voltage signal from the incoming cabinet AH07 of the redundant units in Group A (or the incoming cabinet BH07 of the redundant units in Group B), the PT voltage signal of the busbar in Group A (or the PT voltage signal of the busbar in Group B), and the position signal of the vacuum circuit breaker in the incoming cabinet of the redundant units in Group A (or the position signal of the vacuum circuit breaker in the incoming cabinet of the redundant units in Group B) according to the instructions of the main control panel. Simultaneously, it needs to complete the communication switching (including impedance matching) between the redundant units and Group A or Group B, and synchronize the redundant units with Group A. The redundant units need to switch to synchronize the communication with the units in Group A, and vice versa. It also needs to complete the transmission and switching processing of the differential current protection signals for both groups.

[0065] Based on the acquired and feedback signals, the redundant units then adjust the voltage and frequency, and after synchronization, send synchronous closing and disconnection signals to the incoming line cabinet AH07 of the redundant unit A (or synchronous closing and disconnection signals to the incoming line cabinet BH07 of the redundant unit B). Therefore, in addition to the usual unit control and parallel synchronization control circuits, the redundant unit control panel also has built-in signal acquisition and feedback, parallel communication, and automatic signal control switching control circuits.

[0066] When both sets of diesel generator sets experience a fault in one of their main grid power sources (or mains power), the main control cabinet system receives the corresponding mains power failure signal and issues a start signal to control each diesel generator set in either group A or group B, as well as the redundant generator set. When only one set of mains power is lost, the corresponding diesel generator set in group A or group B starts. The redundant generator set's G6 signal acquisition and output control automatically switches to group A or group B, and the G6 redundant generator set automatically establishes parallel communication with the corresponding group A or group B. After successful startup, the system controls the corresponding generator set's incoming line cabinets AH01 to AH05 (or BH01 to BH06) to synchronously close the circuit breaker. When the G6 redundant generator set controllers are synchronously operating, the control system first controls the interlocking switch cabinets CH01 or CH02 to close, and then controls the G6 generator set's incoming line cabinet AH0... 7 (or BH07) Synchronous closing and parallel operation; each starting unit controls the grounding resistor cabinet to close simultaneously with the unit's startup; the unit that first meets the conditions for load operation closes first to supply power to the A or B group bus; the others then successively synchronize and parallel with the first unit; and one grounding resistor cabinet is kept closed online; when the number of paralleled units reaches the number set by the main control cabinet, the main control cabinet controls the parallel output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10) to close, providing emergency power to the system, and automatically adding or removing units according to the system load. The parallel output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10) has remote closing and opening functions as well as local closing and opening functions. When the power to the grid is restored, the main control cabinet first controls the tripping of the bus output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10), and then controls the tripping of each parallel unit to cool down and shut down according to the procedure; the G6 redundant unit first trips and disconnects, then disconnects the CH01 or CH02 switch cabinet, and then cools down and shuts down according to the procedure.

[0067] When both sets of grid power fail simultaneously, or when the higher-priority set also fails during operation, the G6 redundant unit will automatically switch to the corresponding line or disconnect from the lower-priority line according to the priority settings, and then switch to the higher-priority line for parallel operation. When the higher-priority line is restored to power first, the unit on that line will disconnect and shut down according to the procedure; the G6 redundant unit will then disconnect from the higher-priority unit, and its communication signals, parallel acquisition and feedback, and control lines will switch to the lower-priority set; the redundant unit will then communicate and operate in parallel with the lower-priority unit. After all grid power is restored, the shutdown procedure is the same as described above.

[0068] In addition to automatic mode, the redundant unit control panel and the control panels for Group A and Group B also have manual mode. Users can manually start and stop each unit and synchronize the operation of each incoming line cabinet by pressing buttons on the control panel. Users can also unload each unit, transfer the load, disconnect the corresponding incoming line cabinet, and shut down the unit for cooling by pressing buttons.

[0069] Number 12 is the system unit main control cabinet, equipped with a touch screen, which can remotely monitor and operate the units and their feeder cabinets (AH09, AH10, BH09, BH10). It can also manually start each unit and control the opening and closing of each unit's incoming line cabinet; monitor the operating parameters and alarm information of each unit's engine and generator; and has multiple functions such as event logging and historical data query. It features automatic, semi-automatic, and fully automatic modes for convenient on-site commissioning and testing. In fully automatic mode, the main control cabinet, based on a mains power fault signal, sends an A-group or B-group start / parallel operation command via Ethernet, thereby controlling the feeder cabinets to close and supply power.

[0070] When multiple redundant generating units are configured (i.e., m > 1), the same circuit can be used to allow multiple redundant units to operate simultaneously as either Group A or Group B, or, as needed, some units can be synchronously paralleled with Group A redundancy while others are synchronously paralleled with Group B redundancy. The system is equipped with comprehensive unit protection and switchgear operation error prevention functions. Each unit's incoming line switchgear is in the working position without local operation functions, preventing closing without power generation, preventing asynchronous closing, and preventing opening due to load transfer. Unit control and synchronization functions are integrated into the control systems of each unit (AC01 to AC02); the main control cabinet does not involve unit synchronization functions.

[0071] This application proposes a requirement for one high-power generator set to provide redundant parallel power supply for two sets of grid emergency backup power supplies using N+1 diesel generator sets. Similarly, two or more high-power generator sets (N+m, m>1) can provide N+2 or more generator sets for two sets of grid emergency backup power supplies with redundant power. Group A has 5 generator sets, Group B has 6, with one redundant generator set and two output cabinets for each of Group A and Group B. An example of emergency power supply redundancy configuration circuits and schemes is provided. Similar variations in the number of generator sets, main system configurations, control circuits, and main control systems will not be elaborated here. Auxiliary control harnesses may also include motorized louver linkage. If the CH01 and CH02 isolating switch cabinets are removed, and the primary line of generator set #6 is split into two direct lines to switch cabinets A07# and B07#, with electrical (and mechanical) interlocks between the two switch cabinets, redundant backup for one generator set and two sets (sections) of emergency power supplies can be achieved, with similar circuit changes. The grounding resistor cabinet's opening and closing control is controlled separately by the unit controller; centralized control can also be used. This application takes high-power high-voltage (10.5KV / 6.3KV) as an example. Similarly, this application can be applied to redundant power supply of low-voltage high-power generators.

[0072] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the redundant generator set configuration method of this application will be described in detail below with reference to specific embodiments.

[0073] This embodiment relates to a specific method for configuring redundant generator sets, such as... Figure 5As shown, it includes:

[0074] Obtain the status of the first diesel generator set and the status of the second diesel generator set, and obtain the status of the first generator set and the status of the second generator set respectively;

[0075] After obtaining the status of the first generator set and the status of the second generator set respectively, if the first generator set is de-energized and the second generator set is energized, the redundant generator set supplies power to the first diesel generator set; if the first generator set is energized and the second generator set is de-energized, the redundant generator set supplies power to the second diesel generator set; if both the first and second generator sets are energized, it is determined that no power supply is needed for the first and second diesel generator sets.

[0076] When both the first and second generator sets are in a power outage state, the redundant generator sets supply power to either the first or second diesel generator set according to the first or second priority. The first priority is the priority of the first diesel generator set, and the second priority is the priority of the second diesel generator set. The first and second priorities are of different levels.

[0077] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0078] This application also provides a redundant generator set. It should be noted that the redundant generator set in this application can be used to execute the configuration method for redundant generator sets provided in this application. The redundant generator set is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the redundant generator set described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0079] The redundant generator set provided in the embodiments of this application will be described below.

[0080] Figure 6 This is a schematic diagram of a redundant generator set according to an embodiment of this application. Figure 6 As shown, the redundant generator set includes:

[0081] Acquisition unit 61 is used to acquire the status of each of the aforementioned diesel generator sets;

[0082] The first processing unit 62 is configured to, when all of the aforementioned diesel generator sets are in a state of power outage or power supply, connect one of the aforementioned redundant generator sets in parallel according to the priority of each of the aforementioned diesel generator sets, so as to supply power to the power distribution system. The order of the priorities is determined according to the importance of each of the aforementioned diesel generator sets in supplying power to the load.

[0083] In this system, a unified communication interface is established between redundant generator sets and all diesel generator sets, enabling real-time acquisition of status information for each set, including but not limited to grid outages, generator operating status, and fault conditions. This improvement simplifies the system architecture by reducing the number of independent communication links, making the control logic and hardware configuration more centralized and unified, thereby reducing overall cost and complexity. Priority is set based on the importance and urgency of the loads served by each diesel generator set, ensuring that the most important set receives priority power supply in the event of a power outage. Compared to traditional fixed redundancy configurations, dynamic priority decision-making utilizes the power output of redundant generator sets more efficiently, avoiding resource waste, especially when power demand fluctuates greatly or the urgency of different sets of loads changes, providing greater flexibility and response speed. Using the method described in this application, only one or a few redundant generator sets are needed to cover all sets. Through intelligent switching and priority control, any set can be connected in parallel in emergencies to supply power to the distribution system. This configuration significantly reduces the total number of generator sets and auxiliary facilities required, thereby significantly reducing construction and operating costs. This solves the problem of the existing solution, which requires each diesel generator set to be equipped with a redundant generator set as an emergency power source, resulting in complex wiring and high costs.
