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

[0008] Optionally, after obtaining the first unit status and the second unit status respectively, the method also includes: when the first unit status is power-off and the second unit status is power-on, the redundant generator set supplies power to the first diesel generator set; when the first unit status is power-on and the second unit status is power-off, the redundant generator set supplies power to the second diesel generator set.

[0009] Optionally, in the process of supplying power to the first diesel generator set or the second diesel generator set according to the first priority and the second priority, the method further includes: the redundant generator set receives and responds 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 communicates with the redundant generator set; the redundant generator set receives and responds 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 also includes: the redundant generator set predicts a target fault-prone unit based on the historical parameter data and time series prediction algorithm of each of the diesel generator sets, and the target fault-prone unit represents the diesel generator set that is prone to failure among all the diesel generator sets; and performs preheating treatment on the redundant generator set, and the preheating treatment includes preheating the coolant and engine oil of the redundant generator set to reduce mechanical wear when the redundant generator set is started.

[0011] Optionally, the method further includes: obtaining environmental information, the environmental information including the temperature, humidity, grid load and health status of the redundant generator set; and adjusting the priority of at least part of all the redundant generator sets according to the environmental information.

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

[0013] Optionally, the redundant generator set supplies power to the first diesel generator set, comprising: switching a switch from a first position to a second position to connect the redundant generator set and the first diesel generator, so that the redundant generator set supplies power to the first diesel generator set, the switch position comprising the first position, the second position, and a third position, the switch being 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, including: switching the position of the switch from the first position to the third position to connect the redundant generator set and the second diesel generator, so that the redundant generator set supplies power to the second diesel generator set.

Priority is set based on the importance and urgency of the loads served by each diesel generator set, ensuring that the most important group receives priority power supply in the event of an emergency power outage. Compared to traditional fixed redundancy configurations, dynamic priority decision-making can more efficiently utilize the power output of redundant generator sets and avoid resource waste, especially when power demand fluctuates significantly or the urgency of loads in different groups varies.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] As introduced in the background technology, in order to ensure the safe and reliable emergency power supply of diesel generator sets, data centers or core hub communication base stations will configure multiple groups of high-power generator sets according to the power capacity of each server room and the power capacity of the supporting cooling system and their importance, and operate these high-power generator sets in parallel so that the parallel high-power generator sets can provide backup emergency power for the data center room, resulting in complex lines and high costs. In order to solve the problem that the existing solution configures a redundant generator set as an emergency power supply for each group of diesel generator sets, resulting in complex lines and high costs, the embodiments of the present application provide a configuration method for redundant generator sets and a diesel power generation system.

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

[0032] In this embodiment, a method for configuring a redundant generator set is provided, which is applied to the controller of a redundant generator set in a power generation system. The above-mentioned power generation system also includes multiple groups of diesel generator sets, and any group of the above-mentioned diesel generator sets includes multiple diesel generators. The above-mentioned redundant generator sets communicate with all of the above-mentioned diesel generator sets respectively. It should be noted that the steps shown in the flowchart of 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 can be executed in an order different from that here.

[0033] Figure 1 FIG. 1 is a flow chart of a configuration method for a redundant generator set according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0034] Step S101, obtaining the status of each of the above diesel generator sets;

[0035] Step S102, when all of the above-mentioned diesel generator sets are in the state of power off or power supply, the above-mentioned redundant generator sets are operated in parallel for one group of all the above-mentioned diesel generator sets according to the priority of each of the above-mentioned diesel generator sets to supply power to the distribution system. The order of the above-mentioned priorities is determined according to the importance of each of the above-mentioned diesel generator sets in supplying electricity to the load.

[0036] In existing solutions, each diesel generator set has its own redundant generator set, which means the system has multiple independent communication links, each requiring separate hardware and software support, undoubtedly increasing system complexity and cost. In contrast, in the present application, a unified communication interface is established between the redundant generator set and all diesel generator sets, enabling real-time access to status information from each diesel generator set, including but not limited to grid outages, generator set 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 the present application can intelligently select which generator set to power based on a preset priority order when all diesel generator sets lose power or are powered on. Priority is determined based on the importance and urgency of the loads served by each generator set, ensuring that the most important generator set receives power first in the event of an emergency power outage. Compared to traditional fixed redundancy configurations, dynamic priority decision-making allows for more efficient utilization of the redundant generator set's power output, avoiding resource waste. This approach provides greater flexibility and responsiveness, especially when power demand fluctuates significantly or the urgency of loads in different groups varies. In existing solutions, ensuring emergency power supply for each diesel generator set requires a redundant generator set. This not only results in a surge in the number of devices but also incurs high costs due to the need to separately establish supporting infrastructure (such as fuel storage, cooling systems, and noise reduction facilities). However, the method of the present invention only requires one or a small number of redundant generator sets to cover all groups. Through intelligent switching and priority control, any group can be operated in parallel to power the distribution system in an emergency. This configuration significantly reduces the total number of generator sets and ancillary facilities required, thereby significantly reducing construction and operating costs. This solves the problem of existing solutions requiring each diesel generator set to have a redundant generator set as an emergency power source, resulting in complex wiring and high costs.

[0037] In one embodiment of the present application, the plurality of 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, and obtaining the status of the first generator set and the status of the second generator set, respectively;

[0038] The above-mentioned redundant generator sets operate in parallel for one group of all the above-mentioned diesel generator sets according to the priority of each of the above-mentioned diesel generator sets to supply power to the power distribution system, including: the above-mentioned redundant generator sets supply power to the first diesel generator set or the second diesel generator set according to the first priority and the second priority, 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 at 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, the redundant generator sets will prioritize powering higher-priority diesel generator sets (i.e., more critical systems or loads). This ensures the normal operation of critical systems even with limited resources, significantly improving overall system reliability and efficiency. Traditional methods require a redundant generator set for each diesel generator set, significantly increasing equipment and maintenance costs. However, the method of the present invention only requires a single redundant generator set to provide emergency power support for multiple diesel generator sets, significantly reducing equipment investment and operating and maintenance costs. A unified communication mechanism is established between the redundant generator set and all other diesel generator sets, reducing the complexity of communication lines and the potential failure rate caused by excessive lines, making the overall power generation system architecture simpler and more stable. When all diesel generator sets are out of power, the redundant generator sets can quickly start supplying power according to priority order without human intervention, significantly shortening the time from power outage to power restoration and improving the system's emergency response speed.

[0040] In one embodiment of the present application, after obtaining the first unit status and the second unit status respectively, the above method also includes: when the above first unit status is power-off and the above second unit status is power-on, the above redundant generator set supplies power to the above first diesel generator set; when the above first unit status is power-on and the above second unit status is power-off, the above redundant generator set supplies power to the above second diesel generator set.

[0041] Specifically, it can rapidly respond to a single unit outage without having to wait for all units to lose power before activating the redundant generator sets. Once a power supply problem is detected for any unit, the redundant generator sets immediately intervene to provide power support, significantly shortening emergency response time and reducing the likelihood of service interruptions. By precisely locating the outage unit and providing power only to that unit, the impact of the power outage can be limited to a smaller area. This means that even if a single unit fails, the remaining units and the loads they serve can continue to operate normally, ensuring minimal disruption to the overall operation of critical facilities such as data centers and communication base stations. When one diesel generator set is operating normally, the redundant generator sets are not blindly activated, avoiding unnecessary energy waste and startup costs. This approach ensures that the startup and operation of the redundant generator sets are based on actual needs, improving energy efficiency. Even in the event of a partial power outage, the system can maintain operation through the timely intervention of the redundant generator sets. This approach enhances overall system reliability, providing stable power support, especially during high-load or emergency situations, and reducing the risk of system failures caused by unstable power supply.

[0042] In one embodiment of the present application, in the process of supplying power to the first diesel generator set or the second diesel generator set according to the first priority and the second priority, the method further includes: the redundant generator set receives and responds to the first preset operation acting on the touch screen controller to supply power to the first diesel generator set, and the touch screen controller communicates with the redundant generator set; the redundant generator set receives and responds to the 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 operator control of redundant generator sets. Through an intuitive user interface, operators can quickly make decisions and execute appropriate power supply operations without complex physical switching or tedious manual operations, improving operational convenience and efficiency. Preset operations performed by operators via the touchscreen controller are responded to in real time by the redundant generator sets. This means that in an emergency, the redundant generator set can be quickly activated to power the required diesel generator set, shortening the delay between decision-making and execution and enhancing the system's real-time responsiveness. Control via the touchscreen controller allows operators to 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 precision but also ensures system stability and efficiency in complex and changing environments. Touchscreen controllers typically include input validation to prevent operator errors. When controlling a redundant generator set to power either the primary or secondary diesel generator set, the system uses the touchscreen controller's confirmation function to ensure that operations are only executed when they comply with safety and operating specifications, thereby reducing operational risks and improving the safety of the entire power generation system.

[0044] In one embodiment of the present application, before obtaining the status of each of the above-mentioned diesel generator sets, the above-mentioned method also includes: the above-mentioned redundant generator sets predict target fault-prone units based on historical parameter data and time series prediction algorithms of each of the above-mentioned diesel generator sets, and the above-mentioned target fault-prone units represent the above-mentioned diesel generator sets that are prone to failure among all the above-mentioned diesel generator sets; and perform preheating treatment on the above-mentioned redundant generator sets, and the above-mentioned preheating treatment includes preheating the coolant and engine oil of the above-mentioned redundant generator sets to reduce mechanical wear when the above-mentioned redundant generator sets are started.

[0045] Specifically, the present application also provides a specific usage scenario for performing preheating treatment on redundant generator sets: in large data centers, stable power supply is key to ensuring 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 when the main power supply fails. Taking into account the different 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, fuel consumption rate, etc., to predict which units may fail in the near future, that is, to identify target units prone to failure, is a key measure to improve the overall reliability of the system.

[0046] Implementation steps: The data center maintenance team regularly collects and summarizes operating data from all diesel generator sets, including but not limited to operating hours, ambient temperature, fuel consumption rate, coolant temperature, and oil pressure. This data is then fed into time series prediction algorithms, such as ARIMA models and long-short-term memory (LSTM) networks, to predict the failure probability of each generator set. This step leverages the value of historical data to more accurately identify potential sources of failure risk. Through algorithmic analysis, units with a higher probability of failure are marked as target failure-prone units. This prediction provides early warning, providing decision-making support for the maintenance and management team and optimizing emergency preparedness. When a diesel generator set (such as the first diesel generator set) is predicted to be a target failure-prone unit, the system automatically or manually initiates the preheating process for the redundant generator set. This preheating process involves heating the coolant and oil, ensuring that the redundant generator set can start quickly when needed without compromising performance due to mechanical wear caused by low temperatures.

[0047] The beneficial effects of performing preheating of redundant generator sets in a specific usage scenario: Preheating ensures that redundant generator sets can start quickly when necessary, reducing startup delays, which is particularly critical for locations such as data centers that have extremely high requirements for power continuity; through prediction and preprocessing, the downtime caused by generator set startup problems can be effectively reduced, improving the overall availability of the system. The advance prediction of target fault-prone units helps the maintenance team to more efficiently arrange preventive maintenance and resource scheduling, avoid emergency repairs caused by sudden failures, and thus reduce maintenance costs; preheating reduces mechanical wear during the startup process, helps extend the service life of the generator set, reduces the frequency of equipment replacement, and further saves costs; overall, this prediction-based preheating mechanism significantly improves the reliability of the backup power generation system and provides a safer and more stable power guarantee for the data center. Combined with a touch screen controller and time series prediction algorithm, operators can more easily monitor and control the generator set. At the same time, the intelligence level of the system is improved, reducing the complexity and potential errors of human operation.

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

[0049] Step S201, obtaining environmental information, the environmental information including the temperature, humidity, grid load and health status of the redundant generator set;

[0050] Step S202: adjusting the priorities of at least part of all the redundant generator sets according to the environmental information.

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

[0052] Implementation steps: The controllers of redundant generator sets continuously monitor various environmental parameters, including ambient temperature, humidity, grid load, and their own health. For example, cold winter conditions may hinder generator start-up, while hot summer temperatures can reduce cooling system efficiency and potentially lead to overheating. Real-time changes in grid load reflect the intensity of the system's power demand, while the health of the generator sets directly impacts their ability to start and operate effectively. Based on this environmental information, the controllers apply intelligent algorithms (such as machine learning and fuzzy logic) to analyze the potential impact of various parameters on generator set performance and adjust the priority of the redundant generator sets accordingly. For example, a generator set with a temperature below a certain threshold may be prioritized to avoid potential problems during a cold start. Conversely, a generator set with a moderate temperature and good health may be prioritized as the preferred emergency power source. In the event of a grid failure or a sudden increase in power demand, the system uses this adjusted priority order to rapidly activate and put the most suitable redundant generator set into operation. 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 a specific usage scenario of adjusting the priority of at least some of all redundant generator sets are as follows: giving priority to the generator sets with the best health and the strongest environmental adaptability, which can restore power supply in the shortest time and reduce the duration of service interruption; by monitoring the grid load and its own health, redundant generator sets can avoid starting under adverse conditions, reduce the risk of equipment damage, and extend the service life of the generator sets; reduce maintenance costs: intelligently adjust the priority so that the generator sets operate under optimal conditions, reduce the wear and tear caused by frequent starting, and reduce maintenance and repair costs; priority adjustment based on environmental information ensures that the generator sets can operate stably under various environmental conditions, and improves the reliability and stability of the entire emergency power supply system. By considering environmental factors, the system can more intelligently allocate the startup order of redundant generator sets, avoid resource waste, and achieve more efficient energy management; whether in extreme climate conditions or in scenarios where grid demand fluctuates drastically, the system can respond flexibly and maximize the effectiveness and safety of power supply by dynamically adjusting priorities.

[0054] In one embodiment of the present application, Figure 3 As shown, powering the first diesel generator set includes the following steps:

[0055] Step S301: obtaining a power mapping relationship, wherein the power mapping relationship is a relationship between priority and power supply;

[0056] Step S302: determining a target power supply according to the power mapping relationship and the first priority.

[0057] 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 is similar and will not be elaborated here. Through dynamic adjustment of the power mapping relationship, the redundant generator set can provide accurate power supply according to the actual needs of the first diesel generator set, avoiding the situation of excess or insufficient power and realizing efficient utilization of power resources. When the system detects that the priority of the first diesel generator set has been increased, the redundant generator set can quickly adjust the power supply and quickly respond to changes in power demand. Especially in emergency situations, it can provide timely power guarantee for critical businesses. By ensuring that the power supply matches the priority, unstable operation or safety issues caused by overload or underload of the generator set are avoided, and the stability and safety of the entire system operation are improved.

[0059] In one embodiment of the present application, the redundant generator set supplies power to the first diesel generator set, comprising: switching a switch from a first position to a second position to connect the redundant generator set and the first diesel generator, so that the redundant generator set supplies power to the first diesel generator set, wherein the position of the switch includes the first position, the second position, and the third position, and the 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, including: switching the position of the switch from the first position to the third position to connect the redundant generator set and the second diesel generator, 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 grid power is interrupted, the switch can be quickly adjusted to allow the redundant generator set to quickly connect and begin supplying power. This not only quickly restores power to the second diesel generator set's service area but also isolates the fault, preventing the faulty generator set from impacting the stable operation of the entire system. Switching to the third position is typically very fast, significantly reducing the power outage in the second diesel generator set's service area. This is crucial for ensuring the continuous operation of critical facilities such as data centers and communication base stations, effectively preventing business losses and data security risks caused by prolonged power outages. Traditional redundancy mechanisms may require a separate redundant generator set for each diesel generator set. However, with a flexible switch design, a single redundant generator set can switch between different positions (primary, third, etc.), providing redundant support for multiple diesel generator sets, enhancing overall system redundancy and reducing equipment investment and space usage. Dynamic allocation of redundant generator sets ensures maximum resource utilization. During normal operation, the redundant generator set is in standby mode, reducing unnecessary energy consumption and equipment wear. In the event of a fault, the power needs of the outage unit can be quickly located and met, avoiding redundant resource waste.

[0062] like Figure 4 As shown, the diesel power generation system includes: a first diesel generator set 100, a second diesel generator 200, a redundant generator set 300, a switching switch 400 and a touch screen controller 500. The switching switch is used to electrically connect the first diesel generator set, the second diesel generator and the redundant generator set, and the touch screen controller is electrically connected to the redundant generator set.

Each unit communicates with the main control panel's PLC through the main control panel's internal switch.Serial number 23 is the control and signal feedback cable from the unit's main control panel to the A-group busbar feeder switchgear AH09 and AH10; Serial number 24 is the control and signal feedback cable from the unit's main control panel to the B-group busbar feeder switchgear BH09 and BH10; Serial number 25 is the communication cable from the unit's main control panel to the power supply monitoring system; Serial number 25 is the mains fault feedback input signal cable.

[0064] The system includes five diesel generator sets (Group A) G1 to G5, six diesel generator sets (Group B) G7 to G12, and redundant diesel generator set G6; G6 is a redundant swing parallel unit. The primary system utilizes the isolation and interlocking switchgear CH01 / CH02 between the Group A and Group B busbars. Parallel operation is achieved via the Group A redundant unit incoming paralleling cabinet AH07, and via the Group B redundant unit incoming paralleling cabinet BH07. CH01 / CH02 feature electrical and mechanical interlocking. If CH01 is closed, CH02 cannot be closed, and vice versa. To achieve smooth synchronous paralleling between high-voltage, high-power diesel generator sets, the units must be able to communicate with each other, use a common busbar, and employ the same busbar T signal. The differential current protection signal must also be disabled accordingly. To achieve swing parallel operation of the redundant units with the busbars of Group A or Group B, the redundant unit control panel AC06 automatically collects the incoming PT voltage signals of the incoming cabinet AH07 (or the incoming cabinet BH07) of the redundant units of Group A (or the PT voltage signals of the incoming cabinet BH07 of the redundant units of Group B), the PT voltage signals of the busbars of Group A (or the PT voltage signals of the busbars of Group B), and the position signals of the vacuum circuit breaker of the incoming cabinet of the redundant units of Group A (or the position signals of the vacuum circuit breaker of the incoming cabinet of the redundant units of Group B) according to the instructions of the main control panel. At the same time, the redundant units need to complete communication switching (including impedance matching) with Group A or Group B and synchronize parallel operation with Group A. The redundant units need to switch to synchronize parallel communication with the units of Group A, and vice versa. At the same time, the transmission and switching processing of the two sets of differential current protection signals need to be completed.

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

[0066] When one of the two sets of diesel generator sets' supporting grid power (or mains) fails (primary or standby), the main control cabinet system receives the corresponding group mains failure signal and sends a start-up signal to control the diesel generator sets in group A or group B and the redundant units. When only one set of supporting mains fails, the corresponding diesel generator set in group A or group B starts; the redundant unit G6 signal acquisition and output control automatically switches to group A or group B, and the G6 redundant unit automatically communicates with the corresponding group A or group B in parallel. After the unit is successfully started, the corresponding unit's incoming cabinets AH01 to AH05 (or BH01 to BH06) are controlled to synchronize and close. When the G6 redundant unit controllers synchronize and close, the control system first controls the interlocking switch cabinet CH01 or CH02 to close, and then controls the G6 unit incoming cabinet AH0 7 (or BH07) synchronizes closing and paralleling. Each unit starting up controls the closing of the grounding resistor cabinet. The first unit meeting the load-carrying conditions closes first, energizing the Group A or Group B busbar. The remaining units follow in parallel with the first unit, maintaining one closed grounding resistor cabinet online. When the number of paralleled units reaches the number configured in the master control cabinet, the master control cabinet controls the closing of parallel output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10) to provide emergency power to the system and automatically add or remove units based on system load. Parallel output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10) has both remote and local closing and opening functions. When the network power is restored, the main control cabinet first controls the bus output feeder cabinet 9 (AH09 / AH10 or BH09 / BH10) to open, and then controls the parallel units to open and shut down according to the program; the G6 redundant unit is first opened and de-energized, and then the CH01 or CH02 switch cabinet is disconnected, and then the cooling shutdown is carried out according to the program.

[0067] If both power lines fail simultaneously, or if the higher-priority line also fails during operation, the G6 redundant units will automatically switch to the corresponding line based on the priority setting, or decouple from the lower-priority line and switch to the higher-priority line for parallel operation. If the higher-priority line resumes power first, the units on that line will be decoupled and shut down according to the program. After the G6 redundant units are decoupled from the higher-priority units, communication signals, parallel data collection and feedback, and control lines will be switched to the lower-priority line. The redundant units will then communicate and operate in parallel with the lower-priority units. Once all power lines are restored, the shutdown procedure will be the same as described above.

[0068] In addition to the automatic mode, the redundant unit control panel and the group A and group B unit control panels are also equipped with a manual mode. On the operation panel, you can manually start and stop each unit and synchronize the closing and closing of each incoming cabinet by pressing buttons; you can also press buttons to unload each unit, transfer the load, de-energize the corresponding incoming cabinet, and shut down the unit for cooling.

[0069] Number 12 is the system's main control cabinet. Equipped with a touchscreen, it allows remote monitoring and operation of the gensets and their feeder cabinets (AH09, AH10, BH09, and BH10). It can manually start each genset and control the closing and opening of each genset's incoming cabinet. It also monitors the operating parameters and alarms of each genset's engine and generator. It features event logging and historical data query capabilities. It operates in automatic, semi-automatic, and fully automatic modes, facilitating on-site commissioning and testing. In fully automatic mode, the main control cabinet, based on a mains fault signal, issues a start-up and paralleling command for Group A or Group B via Ethernet, which in turn controls the closing and powering of the feeder cabinets.

[0070] When multiple redundant units are configured (i.e., when m > 1), the same circuit can be used to simultaneously parallel multiple redundant units in Group A or Group B. Alternatively, as needed, some units can be synchronized with Group A and others with Group B. The system configuration includes comprehensive unit protection and switchgear operation error prevention features. Each unit's incoming switchgear is in the working position and lacks local operation capabilities. This prevents closing without generating power, closing without synchronization, and opening to transfer loads. Unit control and synchronous paralleling functions are integrated into each unit's control system (AC01 to AC02); the master control cabinet is not involved in unit synchronous paralleling.

[0071] This application proposes a single high-power generator set providing redundant parallel power to two grid-connected emergency backup power supply systems, each with N+1 diesel generator sets. Similarly, two or more high-power generator sets (N+m (m>1)) can be used to provide redundant power to two grid-connected emergency backup power supply systems, each with N+2 or more generator sets. Group A has five generators, Group B has six generators, and Groups A and B each have two output cabinets. The redundant configuration circuit and solution for the emergency power supply example are described. Similar variations in the number of units, system configuration, control circuitry, and main control system are not detailed here. The auxiliary control wiring harness can also include linkage for electric blinds. If the system removes the CH01 and CH02 isolation switchgears, the primary line of unit 6 is split into two routes, directly connected to the A07# and B07# switchgears. The two switchgears are equipped with electrical (and mechanical) interlocks. This can also achieve redundant backup for one generator set and two emergency power supply groups (sections), with similar circuit variations. The closing and opening control of the grounding resistor cabinet is controlled individually by the unit controller; centralized control can also be used. This application takes high-power and high-voltage (10.5KV / 6.3KV) as an example. Similarly, this application can be applied to redundant power supply of low-voltage and high-power generators.

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

[0073] This embodiment relates to a specific configuration method of redundant generator sets, such as Figure 5As shown, including:

[0074] Acquire the state of the first diesel generator set and the state of the second diesel generator set, and obtain the state of the first unit and the state of the second unit respectively;

[0075] After respectively obtaining the status of the first generator set and the status of the second generator set, when the status of the first generator set is off and the status of the second generator set is on, the redundant generator set supplies power to the first diesel generator set; when the status of the first generator set is on and the status of the second generator set is off, the redundant generator set supplies power to the second diesel generator set; when the status of the first generator set and the status of the second generator set are both on, it is determined that there is no need to supply power to the first diesel generator set and the second diesel generator set;

[0076] When the first unit status and the second unit status are power off, the redundant generator set supplies power to the first diesel generator set or the second diesel generator set according to the first priority and the 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 priority and the second priority are different levels.

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

[0078] The embodiments of the present application also provide a redundant generator set. It should be noted that the redundant generator set of the embodiments of the present application can be used to execute the configuration method for the redundant generator set provided in the embodiments of the present application. The redundant generator set is used to implement the above-mentioned embodiments and preferred implementation methods, and the details that have been explained will not be repeated here. As used below, the term "module" can be 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, implementation in hardware, or a combination of software and hardware, is also possible and conceivable.

[0079] The following introduces the redundant generator set provided in the embodiment of the present application.

[0080] Figure 6 Schematic diagram of a redundant generator set according to an embodiment of the present application. Figure 6 As shown, the redundant generator set includes:

[0081] An acquisition unit 61 is used to acquire the status of each of the above diesel generator sets;

[0082] The first processing unit 62 is used for, when all of the above-mentioned diesel generator sets are in the state of power off or power supply, for the above-mentioned redundant generator sets to operate in parallel for one group of all the above-mentioned diesel generator sets according to the priority of each of the above-mentioned diesel generator sets to supply power to the distribution system. The order of the above-mentioned priorities is determined according to the importance of each of the above-mentioned diesel generator sets in supplying electricity to the load.

[0083] A unified communication interface is established between the redundant generator sets and all diesel generator sets, enabling real-time access to status information for each diesel generator set, including but not limited to grid outages, generator set 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 group receives priority power supply in the event of an emergency power outage. Compared to traditional fixed redundancy configurations, dynamic priority decision-making can more efficiently utilize the power output of redundant generator sets and avoid resource waste, especially when power demand fluctuates significantly or the urgency of loads in different groups varies. This approach provides greater flexibility and responsiveness. Using the method of the present application, only one or a small number of redundant generator sets are needed to cover all groups. Through intelligent switching and priority control, any group can be operated in parallel to power the distribution system in an emergency. This configuration significantly reduces the total number of generator sets and ancillary facilities required, significantly reducing construction and operating costs. This solves the problem that the existing solution configures a redundant generator set as an emergency power supply for each group of diesel generator sets, which makes the circuits complicated and the cost high.
