[0026] As described in the background section, in the prior art, lubrication is performed only after the engine receives the start command, which prolongs the overall start-up time of the generator set.

[0030] This embodiment provides a response control method for a generator set that runs on a mobile terminal, computer terminal, or similar computing device. 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. Also, 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.

[0031] Figure 2 This is a flowchart illustrating the response control method for a generator set according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0032] Step S201: When the generator set is in standby mode, perform oil pre-supply operation to meet preset lubrication conditions. During the oil pre-supply operation, monitor and control the engine water temperature within the preset temperature range. The oil pre-supply operation includes pre-supplying oil during the initial power-on phase of the generator set and after the generator set has finished running. The preset lubrication conditions include the oil pressure reaching a preset standard.

[0033] Specifically, when the generator set is in standby mode, an oil pre-supply operation is performed. The purpose is to pre-supply oil before starting to achieve preset lubrication conditions. These preset lubrication conditions refer to the oil pressure reaching a preset standard, ensuring sufficient lubrication of internal engine parts and preventing damage caused by insufficient lubrication during startup. Oil pre-supply and oil pressure monitoring are performed not only in the initial stage after the generator set is powered on, but also for a period after each generator set operation ends and before the next startup, forming a cyclical pre-supply mechanism. This continuously maintains the lubrication state inside the engine, improving starting efficiency.

[0034] To further optimize engine starting performance, engine coolant temperature preheating and control have been introduced to ensure that the engine coolant temperature is maintained within a preset range. This ensures that the engine is in a warm-up state at any time of starting, reducing the negative effects of cold starts, such as increased wear and fuel consumption.

[0035] The oil pre-supply operation and engine coolant temperature monitoring strategy implemented during generator standby significantly enhance the generator set's rapid start-up capability and operational reliability. By periodically pre-supplying the oil during the initial power-on phase and after the generator set's operation ends, the engine is ensured to always be adequately lubricated, effectively preventing mechanical damage caused by insufficient lubrication during startup and extending engine life. Simultaneously, engine coolant temperature monitoring maintains the engine temperature within the optimal preheating range, allowing it to quickly reach operating temperature even in low-temperature environments, further improving starting efficiency and operational performance. This dual protection of oil pre-supply and coolant temperature control ensures that the engine can start quickly and safely at any time, thereby greatly shortening the generator set's response time, especially in emergencies or under high load demands, enabling the rapid provision of stable power.

[0036] Step S202: When the generator sets meet the preset lubrication conditions, the engine water temperature is within the preset temperature range, and the multiple generator sets meet the parallel operation conditions, control the multiple generator sets to operate in parallel. The parallel operation conditions include that the total load demand is greater than the rated output power of a single generator set.

[0037] Specifically, parallel operation refers to the simultaneous connection of multiple generator sets. If there is voltage on the system busbar or other generator sets are already switched on, it is necessary to control the speed and voltage of the generator sets. Once the voltage, frequency, and phase of the generator sets are consistent with those of the busbar, the generator sets send a switching signal to connect to the busbar. When multiple generator sets need to be operated in parallel, that is, when multiple generator sets meet the parallel operation conditions, in addition to ensuring that each generator set has met the aforementioned preset lubrication conditions and preheating requirements, it is also necessary to assess the total load demand. If the total load demand exceeds the rated output power of a single generator set, this means that multiple generator sets need to operate in parallel to share the load and ensure the stability and sufficiency of the power supply.

[0038] Through the above control methods, the generator set can always maintain a good start-up readiness state in standby mode, while parallel operation is an efficient execution when multiple generator sets meet the necessary conditions, ensuring that power supply can be carried out quickly and smoothly under high load demand or other emergency situations, thereby improving the reliability and response speed of the entire power system.

[0039] In this embodiment, when the generator set is in standby mode, an oil pre-supply operation is performed to meet preset lubrication conditions. During the oil pre-supply operation, the engine coolant temperature is monitored and controlled within a preset temperature range. The oil pre-supply operation includes pre-supplying oil during the initial power-on phase of the generator set and after the generator set has finished running. The preset lubrication conditions include oil pressure reaching a preset standard. When the generator set meets the preset lubrication conditions, the engine coolant temperature is within the preset temperature range, and multiple generator sets meet the parallel operation conditions, multiple generator sets are controlled to operate in parallel. The parallel operation conditions include the total load demand exceeding the rated output power of a single generator set. In this scheme, performing the oil pre-supply operation and monitoring the engine coolant temperature in standby mode ensures that the generator set is always in an optimal pre-lubrication and preheating state, thereby accelerating the start-up speed and reducing mechanical wear in the initial start-up phase, achieving rapid power generation. When multiple generator sets need to be operated in parallel, controlling multiple generator sets to operate in parallel can complete the start-up and parallel operation in a very short time, thus solving the problem of long response time of generator sets in the prior art.

[0040] In the specific implementation process, when the generator set is in standby mode, an oil pre-supply operation is performed to meet the preset lubrication conditions, including: after the generator set is powered on, controlling the oil pre-supply to continue for a first preset time; after the generator set finishes running and before it is restarted, controlling the oil pre-supply to continue for the first preset time every second preset time, wherein the oil pre-supply operation is interrupted when the generator set is received as a start command.

[0041] Specifically, after the generator set is powered on, the oil pump begins to pre-supply engine oil. This process lasts for a first preset time, which in this embodiment can be 60 seconds. The start-up of the oil pump quickly establishes oil circulation, delivering lubricant to various critical engine components, such as pistons, crankshafts, and connecting rod bearings, thus providing sufficient lubrication before the generator set officially starts. This step is crucial for preventing dry friction during engine startup, reducing component wear, and ensuring a smooth engine start.

[0042] After the generator set finishes operation and before its next start, it enters a maintenance cycle. During this cycle, an oil pre-supply operation is performed every second preset time (in this embodiment, the second preset time can be 48 hours) for the same first preset time (e.g., 60 seconds). This cyclical pre-supply mechanism ensures that the engine maintains good lubrication even during long periods of standby, ready to respond to start-up commands. This pre-supply not only reduces start-up delays but also lowers the risk of starting the engine in an unlubricated state.

[0043] Once a generator set start command is received, the ongoing oil pre-supply operation will be immediately interrupted to ensure that the generator set can respond quickly to the start-up demand. This mechanism prioritizes the generator set's starting efficiency, avoids conflicts between the pre-supply operation and the start-up process, and ensures that the generator set can start supplying power without delay in emergency situations or when a rapid response is required.

[0044] By employing an oil pre-supply mechanism during generator standby, sufficient lubrication and rapid response before engine start-up are achieved. When the generator is powered on, a continuous oil pre-supply operation is performed to ensure that all engine components are pre-lubricated, effectively preventing dry friction during initial startup and reducing engine wear. Furthermore, during the standby period between the end of each run and the next start-up, the generator restarts the oil pre-supply at set time intervals. This cyclical pre-supply process further ensures that the engine is in optimal lubrication condition at any starting point, shortening the time from the start command to actual start-up and improving the generator's starting efficiency. When the generator receives a start command, the ongoing oil pre-supply operation is immediately interrupted to ensure the generator can quickly respond to starting requirements and provide timely power support. This not only significantly improves the generator's starting speed but also extends engine life and reduces maintenance costs.

[0045] In some embodiments of this application, when the generator set is in standby mode, performing an oil pre-supply operation to meet preset lubrication conditions further includes: simultaneously performing the oil pre-supply operation, collecting the oil pressure at a preset time to obtain an oil pressure value; if the oil pressure value is greater than or equal to a preset value, controlling the generator set to start normally; if the oil pressure value is less than the preset value, controlling the generator set to stop operating and triggering an oil pre-supply circuit fault warning.

[0046] Specifically, during the oil pre-supply operation, the oil pressure value is acquired at a preset time. That is, during the oil pre-supply operation, the ECU (Electronic Control Unit) is simultaneously energized, and oil pre-supply lasts for 60 seconds. At the 57th second (the preset time), the oil pressure is collected to obtain the oil pressure value. This real-time monitoring step accurately reflects the working status of the engine lubrication system, providing objective data to determine whether the oil pre-supply has achieved the expected effect.

[0047] The collected oil pressure value directly determines whether the generator set can start normally. If the oil pressure value is greater than or equal to the preset value, it indicates that a lubricating oil film has been formed inside the engine, providing the safe lubrication conditions required for starting. At this time, the generator set will be allowed to start according to the normal procedure, ensuring smooth engine operation and effectively avoiding damage that may be caused by insufficient lubrication. The preset value can be 0.3 Bar (this value is adjustable).

[0048] Conversely, if the oil pressure detected after the pre-supply operation is lower than the preset value, it indicates a fault in the oil pre-supply circuit, and the lubrication system is not operating normally. In this case, protective measures are immediately taken to prevent the generator set from starting, to avoid serious engine damage caused by forced starting under low lubrication conditions. Simultaneously, an oil pre-supply circuit fault warning will be triggered, alerting operators to check and repair the lubrication system problem, ensuring the safety and reliability of the equipment when restarting after troubleshooting. The warning information is latched and recorded in the warning log, and its display can only be reset using the emergency stop or mute button, effectively ensuring that operators confirm the warning information.

[0049] By monitoring oil pressure in real time during the oil pre-supply operation and using this as the basis for deciding whether to start the generator set, effective management and protection of engine lubrication status are achieved. When the generator set is in standby mode, oil pre-supply is performed, and oil pressure values ​​are collected at preset critical moments (preset times). If the oil pressure reaches or exceeds the preset safety standard, it indicates that the engine is adequately lubricated, and the generator set is allowed to start according to the normal procedure, ensuring smooth engine operation and extending its service life. However, if the oil pressure detected after the pre-supply operation is lower than the preset value, it indicates insufficient lubrication system efficiency or other related faults. To prevent potential engine damage, the generator set will be prevented from starting, and an oil pre-supply circuit fault warning will be triggered immediately, reminding operators to check and repair until the lubrication problem is resolved. This improves the starting safety of the generator set, avoids the risks of starting without sufficient lubrication, and also ensures high operating efficiency and stability of the equipment, providing a more reliable and safer power supply guarantee.

[0050] During the standby state of generator sets, in addition to performing oil pre-supply and water temperature control, an intelligent pre-start mechanism can be introduced. This mechanism, combined with advanced load forecasting algorithms, predicts changes in future electricity demand. Using real-time data collected through networks or sensors, such as weather forecasts, historical electricity consumption records, and current grid conditions, the intelligent pre-start mechanism can predict potential periods of high load demand. Once it is predicted that the future load may exceed the processing capacity of a single generator set, the pre-start steps of multiple generator sets will be activated in advance, including oil pre-supply and engine preheating, rather than simply starting after receiving a start command. In this way, the generator sets can be in optimal condition before demand arrives, significantly shortening the time from pre-start to full parallel operation and improving the response speed to sudden high load situations.

[0051] To shorten the time from generator set startup to parallel operation completion, in some embodiments of this application, when the generator sets meet the preset lubrication conditions, the engine coolant temperature is within the preset temperature range, and multiple generator sets meet the parallel operation conditions, controlling multiple generator sets to perform parallel operation includes: when the generator sets meet the preset lubrication conditions, the engine coolant temperature is within the preset temperature range, and multiple generator sets meet the parallel operation conditions, controlling all generator sets to disconnect their generator excitation; when all generator sets disconnect their generator excitation, controlling the circuit breakers of all generator sets to close; when the circuit breakers of all generator sets close, controlling all generator sets to start simultaneously; and when the engine speed of all generator sets reaches the preset load-bearing speed, simultaneously sending a first excitation signal to each generator set to complete the parallel operation of multiple generator sets.

[0052] Specifically, before the parallel operation begins, a comprehensive check is conducted to ensure that each generator set meets the preset lubrication conditions, that the engine coolant temperature is within the preset temperature range, and that the parallel operation conditions are met. Checking the preset lubrication conditions ensures that all engines have undergone sufficient pre-lubrication before parallel operation, preventing potential damage during startup; monitoring the engine coolant temperature ensures that the engine starts at a suitable temperature, improving starting efficiency and reducing warm-up time; confirming the parallel operation conditions covers the consistency of electrical parameters (such as voltage, frequency, and phase), ensuring that each generator set can operate smoothly and synchronously in parallel.

[0053] After all the above conditions are met, the excitation of all generator sets to be paralleled is first disconnected. Disconnecting the excitation prepares for the paralleling operation and avoids electrical problems caused by excitation instability during the paralleling process. Subsequently, with the excitation disconnected, the circuit breakers of all generator sets are closed. This step connects the output ports of each generator set to the load end or busbar, preparing for the next step of synchronous startup. After the circuit breakers are closed, all generator sets are immediately started simultaneously. Synchronous startup ensures that the engines of each generator set reach operating status at the same time, reducing paralleling difficulties caused by asynchronous starting sequences and further improving paralleling efficiency. When the engine speeds of all generator sets stabilize and reach the preset load-bearing speed, a first excitation signal is simultaneously sent to each generator set. The synchronous transmission of the first excitation signal allows each generator set to simultaneously establish a stable output voltage, thereby completing the paralleling operation and forming a unified power supply. This strategy avoids the paralleling delay and power fluctuations caused by the excitation establishment time difference in traditional paralleling methods, ensuring a fast and smooth paralleling process.

[0054] By systematically controlling the pre-lubrication status of the generator sets, engine water temperature, excitation disconnection, and synchronous start-up, a fast and efficient paralleling strategy is achieved. This strategy not only significantly shortens the paralleling time and improves the response speed of the power supply system, but also ensures the electrical safety and stability of the paralleling process. It is suitable for occasions requiring multiple generator sets to work together to supply power, such as large data centers, industrial facilities, or power system emergency response, greatly improving the reliability and efficiency of power supply.

[0055] The above parallel operation process, through precise control and synchronized operation, enables efficient parallel operation of multiple generator sets while meeting preset lubrication conditions, engine coolant temperature standards, and parallel operation requirements. Specifically, once it is confirmed that all generator sets have reached ideal lubrication conditions, engine coolant temperatures are within suitable operating ranges, and electrical parameters meet parallel operation requirements, the generator excitation of each generator set is first disconnected uniformly. Then, the circuit breaker is quickly closed to create electrical connectivity for parallel operation. Next, all generator sets start synchronously under a unified command, ensuring no delay and avoiding electrical interference caused by asynchronous starting sequences during parallel operation. After all generator sets' engines are running stably and have reached the preset load-bearing speed, excitation signals are synchronously sent to each generator set to quickly establish a stable voltage output, achieving rapid parallel operation of multiple generator sets. This parallel operation strategy shortens the time from generator set startup to parallel operation completion, improves the response speed of power supply, and ensures the safety and stability of the parallel operation process.

[0056] In some embodiments of this application, the method further includes: monitoring the rotational speed of each of the generator sets; if the rotational speed of any of the generator sets does not reach the preset load speed within the static parallel delay time period, determining that the generator set is starting abnormally and identifying the generator set as a faulty generator set; controlling the faulty generator set to exit the static parallel mode and enter the dynamic parallel mode, wherein the static parallel delay time period is the time interval from the closing of the circuit breakers of all the generator sets to the simultaneous sending of the first excitation signal to each of the generator sets.

[0057] Specifically, in the static parallel mode, where the circuit breakers of the aforementioned generator sets close first, followed by the synchronous startup of all generator sets, the real-time speed of each generator set is continuously monitored to verify whether it can accelerate to the preset load-bearing speed as expected. This monitoring process spans the entire static parallel delay period, which is the time interval from the closing of the circuit breakers of all generator sets to the sending of the first excitation signal to each generator set. If, during the static parallel delay period, the speed of any generator set fails to reach the preset load-bearing speed, that generator set is judged to have a startup abnormality and is identified as a faulty generator set. Once a generator set is identified as a faulty generator set, in order not to affect the entire parallel operation process, measures will be taken immediately to remove it from the static parallel mode and switch to the dynamic parallel mode.

[0058] By continuously monitoring the rotational speed and promptly handling anomalies, overall parallel operation failures caused by the starting failure or malfunction of individual generator sets are effectively prevented. This not only enhances the flexibility and fault tolerance of parallel operation but also ensures the stability and reliability of the entire power supply system. Even in the face of sudden faults, it can react quickly to avoid adverse impacts on power demand. Furthermore, the automatic switching mechanism of the dynamic parallel mode can minimize the impact of fault handling on parallel operation time, ensuring the continuity and high quality of power supply.

[0059] Furthermore, controlling the aforementioned faulty generator set to exit the static parallel mode and enter the dynamic parallel mode includes: performing a circuit breaker tripping operation on the aforementioned faulty generator set to isolate the aforementioned faulty generator set; sending a second excitation signal to the aforementioned faulty generator set, thereby causing the aforementioned faulty generator set to enter the aforementioned dynamic parallel mode.

[0060] Specifically, firstly, the circuit breaker of the faulty generator set is tripped. This operation disconnects the output of the faulty generator set from the grid or load, effectively isolating it and preventing its unstable state from interfering with or damaging other normally operating generator sets or the parallel operation of the entire power system. The rapid tripping of the circuit breaker ensures the timeliness and safety of fault handling, minimizing the impact of the fault on power supply continuity. After the faulty generator set is isolated, a second excitation signal is sent to it. This signal differs from the first excitation signal in static parallel mode; the second excitation signal indicates that the faulty generator set has entered dynamic parallel mode. In dynamic parallel mode, the faulty generator set independently starts its excitation system, establishes a stable voltage output, and then monitors its electrical parameters (including voltage, frequency, and phase) until the parallel operation conditions are met. Then, it searches for a synchronization point with the grid or already paralleled generator sets and performs a closing operation, thus reconnecting to the system. Unlike the static parallel mode which directly synchronizes the circuit breaker, the dynamic parallel mode gives the faulty generator set more time and conditions to adjust its own state until it meets the parallel operation standard. This not only improves the success rate of parallel operation, but also ensures the overall performance and safety of the power system.

[0061] The above mechanism ensures the efficiency and reliability of generator parallel operation. Even in the event of a sudden failure of one or more generators, the faulty generator can be quickly switched to dynamic parallel mode to prevent the fault from spreading and to give the faulty generator a chance to recover, thus ensuring the continuity and quality of power supply.

[0062] In some embodiments of this application, during the oil pre-supply operation, monitoring and controlling the engine coolant temperature within a preset temperature range includes: during the oil pre-supply operation, using a forced-type water jacket heater to maintain the engine coolant temperature within the preset temperature range; and adjusting the operating mode of the forced-type water jacket heater according to the real-time ambient temperature.

[0063] Specifically, when the generator set is in standby mode, i.e., during oil pre-supply operation, a forced-type water jacket heater is simultaneously activated to maintain the engine coolant temperature within a preset range. The forced-type water jacket heater is a device specifically designed to control engine coolant temperature. It consists of a water pump, a heating element, and an intelligent temperature control system. With this heater installed, the coolant circulates between the heated water jacket and the engine via a centrifugal pump. The intelligent control system manages the heating process, ultimately maintaining the coolant temperature within the set range. This improves engine starting capability, reduces starting losses, minimizes engine wear, and saves fuel.

[0064] The system continuously monitors the external ambient temperature and dynamically adjusts the operating mode of the forced-action water jacket heater based on this real-time data. This means that in cold environments, the forced-action water jacket heater will increase its heating power to counteract the effects of low temperatures and ensure that the engine coolant temperature does not drop too low; while in warm or hot environments, the forced-action water jacket heater will reduce heating or stop heating completely to prevent the engine from overheating. In this way, it can adapt to various external conditions and always maintain the engine coolant temperature within a predetermined temperature range that is conducive to rapid start-up and operation.

[0065] By simultaneously implementing engine coolant temperature control during oil pre-supply, a comprehensive and highly efficient pre-start management mechanism is established. This mechanism adapts to various environmental conditions, ensuring rapid and safe engine start-up under any circumstances, providing a solid foundation for the high-performance operation of the generator set. The use of a forced-type water jacket heater during the generator set's pre-start phase enables precise management and regulation of the engine coolant temperature, ensuring it remains within the preset optimal temperature range. This strategy not only provides effective engine preheating during oil pre-supply, protecting it from damage caused by cold starts, but also dynamically adjusts the heater's operating mode by intelligently sensing changes in ambient temperature, providing the most suitable hot-state start-up conditions for the engine regardless of extreme cold or heat. Engine starting efficiency and reliability are significantly improved, while energy consumption and mechanical wear during the start-up process are reduced, extending equipment lifespan. Ensuring rapid power supply in emergencies while maintaining long-term system stability and economy reflects a dual consideration for generator set maintenance and efficiency improvement.

[0066] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the generator set response control method of this application will be described in detail below with reference to specific embodiments.

[0067] This embodiment relates to a specific response control method for a generator set. Specifically, it includes two aspects: oil pre-supply and oil pressure judgment, such as... Figure 3 As shown.

[0068] 1. When the generator set is in standby mode, the circulating oil is pre-supplyed according to the set detection time to keep the generator set in a lubricated state.

[0069] Explanation of oil pre-supply logic:

[0070] See Figure 3 After the generator set is powered on, regardless of the controller's operating mode, the controller will pre-supply oil for 60 seconds to effectively prevent operators from forgetting to pump oil before starting the generator set. After the initial oil pre-supply ends or the generator set finishes operation, while the generator set controller is powered on (regardless of operating mode), the generator set will execute a 48-hour pre-supply logic of 60 seconds (interval and pre-supply time are adjustable). Oil pre-supply can be interrupted by an emergency stop, and generator set startup will also interrupt oil pre-supply to ensure priority for generator set startup.

[0071] During the oil pre-supply process, the ECU is simultaneously powered on. The oil pre-supply lasts for 60 seconds. At the 57th second, the oil pressure is collected. If the oil pressure does not reach 0.3 Bar (the judgment value is adjustable), it is determined that the oil pre-supply pressure is insufficient, and the generator set stops. The generator set controller will issue a warning of oil pre-supply circuit failure. The warning information is latched and recorded in the warning record. The display of the warning information can only be reset by the emergency stop or mute button, effectively ensuring that the operator confirms this warning information. If the oil pressure reaches the judgment value, the generator set starts normally.

[0072] 2. The generator set is equipped with a forced water jacket heater to keep the engine water temperature between 25-40℃, ensuring that the engine is always in a warm-up state.

[0073] The forced-type water jacket heater consists of a water pump, a heating element, and an intelligent temperature control system. After installing this heater, the coolant circulates between the heated water jacket and the engine via a centrifugal pump. The intelligent control system manages the heating process, ultimately maintaining the coolant temperature within a set range. This improves engine starting capability, reduces starting losses, minimizes engine wear, and saves fuel.

[0074] To further improve generator set starting efficiency and reduce energy consumption, an adaptive oil pre-supply and coolant temperature control strategy is introduced. This strategy dynamically adjusts based on current engine temperature, oil viscosity, environmental conditions, and generator set usage history. For example, when the engine temperature is already high or the oil viscosity is low, the oil pre-supply time is reduced; in cold environments or for generator sets that have not been used for extended periods, the pre-supply time and heater power are increased. Furthermore, the pre-supply interval and heater operating mode can be automatically adjusted based on the generator set's starting frequency and operating time to achieve optimal maintenance and energy utilization efficiency. This adaptive control strategy not only significantly improves generator set starting speed but also reduces unnecessary energy consumption, optimizes maintenance plans, thereby lowering operating costs and enhancing overall system performance.

[0075] 3. Explanation using the static parallel connection method:

[0076] The controller software has the following capabilities:

[0077] Three-phase voltage acquisition for generators, three-phase current acquisition for loads, sensor data acquisition, input port detection, output port control, data alarm processing, key detection, LED status indication, historical records, controller mode selection, VFD display, speed acquisition, communication control, speed regulation, voltage regulation, multi-unit communication, parallel power distribution of generator units, and mains / busbar three-phase voltage acquisition.

[0078] The controller software enables automatic start-up, shutdown, switch opening and closing of diesel generator sets, as well as comprehensive fault display and protection functions, and allows multiple generator sets to operate in parallel with power evenly distributed.

[0079] Static parallel logic:

[0080] In scenarios requiring rapid parallel operation, the generator circuit breaker needs to be closed first before generating electricity. The working logic is as follows: all generator sets disconnect their generator excitation, the generator circuit breaker closes first, and then the generator sets start simultaneously. When all generators reach their load-bearing speed, they simultaneously send excitation signals, the generator voltage is established, and the parallel operation of the generator sets is completed.

[0081] If the generator unit fails to reach the output excitation condition within the set static parallel delay time, it exits the static parallel mode and switches to dynamic parallel mode. The operating logic is as follows: the generator circuit breaker first trips, outputs generator excitation, and waits for the synchronization condition to be met before closing the circuit. After a static parallel failure, restarting, speed-up and voltage building, and parallel closing are allowed without affecting the normal operation of other generator units.

[0082] The static parallel connection scheme eliminates the time required for the generator to wait for synchronization conditions to be met before closing the circuit in the ordinary parallel connection scheme, thereby improving the power supply speed.

[0083] This application provides a systematic solution to problems affecting generator set pre-lubrication, preheating, and parallel connection after startup, maximizing the performance of the generator set.

[0084] In some applications requiring rapid power response, such as data centers and emergency start-ups, the engine needs to be in a hot standby and lubricated state at all times. By setting up a pre-lubrication and water heating system, the generator set can start faster, reduce engine wear, and achieve rapid power generation.

[0085] Traditional parallel operation is a dynamic parallel operation. The generator set first generates electricity, then finds a synchronization point to close the circuit. After the generator set starts and power generation is normal, if there is no voltage signal on the system bus, a closing status flag is first sent to the other generator sets to be paralleled. Then, the generator closing relay outputs to prevent other generator sets from closing simultaneously. If there is voltage on the system bus or other generator sets are already closed, the controller will control the GOV speed regulation and AVR voltage regulation to synchronize the generator set with the bus. When the synchronization condition is met, a closing signal is sent to connect the generator set to the bus. Once the generator set is connected to the bus, the controller will gradually increase the engine throttle to distribute the load evenly with other paralleled generator sets. Using this dynamic parallel operation, it takes 60-90 seconds for the generator set to close and supply power from the start command. By applying static parallel operation technology, the generator set can start within 10 seconds and complete parallel operation within 11-15 seconds, improving the power supply speed.

[0086] This application also provides a generator set response control device. It should be noted that the generator set response control device of this application can be used to execute the generator set response control method provided in this application. This device 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 device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0087] The response control device for the generator set provided in the embodiments of this application will be described below.

[0088] Figure 4 This is a schematic diagram of a generator set response control device according to an embodiment of this application. Figure 4 As shown, the device includes an execution unit 10 and a first control unit 20.

[0089] The execution unit is used to perform an oil pre-supply operation to meet preset lubrication conditions when the generator set is in standby mode. During the oil pre-supply operation, the unit monitors and controls the engine coolant temperature within a preset temperature range. The oil pre-supply operation includes pre-supplying oil during the initial power-on phase of the generator set and after the generator set has finished running. The preset lubrication conditions include the oil pressure reaching a preset standard.

[0090] The first control unit is used to control multiple generator sets to operate in parallel when the generator sets meet the preset lubrication conditions, the engine coolant temperature is within the preset temperature range, and the multiple generator sets meet the parallel operation conditions. The parallel operation conditions include that the total load demand is greater than the rated output power of a single generator set.

[0091] In standby mode, the generator set performs pre-lubrication and monitors engine coolant temperature to ensure it is always in optimal pre-lubrication and preheating condition, thereby accelerating start-up and reducing mechanical wear in the initial startup phase, achieving rapid power generation. When multiple generator sets need to be operated in parallel, the generator set can be controlled to operate in parallel, enabling startup and paralleling to be completed in a very short time, thus solving the problem of long response time of generator sets in existing technologies.

[0092] In the specific implementation process, the aforementioned execution unit includes a first control module and a second control module. The first control module is used to control the oil pre-supply for a first preset time after the generator set is powered on. The second control module is used to control the oil pre-supply for the first preset time every second preset time interval after the generator set has finished running and before it is restarted. Upon receiving a start command from the generator set, the oil pre-supply operation is interrupted.

[0093] By employing an oil pre-supply mechanism during generator standby, sufficient lubrication and rapid response before engine start-up are achieved. When the generator is powered on, a continuous oil pre-supply operation is performed to ensure that all engine components are pre-lubricated, effectively preventing dry friction during initial startup and reducing engine wear. Furthermore, during the standby period between the end of each run and the next start-up, the generator restarts the oil pre-supply at set time intervals. This cyclical pre-supply process further ensures that the engine is in optimal lubrication condition at any starting point, shortening the time from the start command to actual start-up and improving the generator's starting efficiency. When the generator receives a start command, the ongoing oil pre-supply operation is immediately interrupted to ensure the generator can quickly respond to starting requirements and provide timely power support. This not only significantly improves the generator's starting speed but also extends engine life and reduces maintenance costs.

[0094] In some embodiments of this application, the execution unit further includes a data acquisition module, a third control module, and a fourth control module. The data acquisition module is used to acquire the oil pressure at a preset time while performing the oil pre-supply operation, obtaining an oil pressure value. The third control module is used to control the generator set to start normally when the oil pressure value is greater than or equal to a preset value. The fourth control module is used to control the generator set to stop operating and trigger a fault warning for the oil pre-supply circuit when the oil pressure value is less than the preset value.

[0095] By monitoring oil pressure in real time during the oil pre-supply operation and using this as the basis for deciding whether to start the generator set, effective management and protection of engine lubrication status are achieved. When the generator set is in standby mode, oil pre-supply is performed, and oil pressure values ​​are collected at preset critical moments (preset times). If the oil pressure reaches or exceeds the preset safety standard, it indicates that the engine is adequately lubricated, and the generator set is allowed to start according to the normal procedure, ensuring smooth engine operation and extending its service life. However, if the oil pressure detected after the pre-supply operation is lower than the preset value, it indicates insufficient lubrication system efficiency or other related faults. To prevent potential engine damage, the generator set will be prevented from starting, and an oil pre-supply circuit fault warning will be triggered immediately, reminding operators to check and repair until the lubrication problem is resolved. This improves the starting safety of the generator set, avoids the risks of starting without sufficient lubrication, and also ensures high operating efficiency and stability of the equipment, providing a more reliable and safer power supply guarantee.

[0096] To shorten the time from generator set startup to parallel operation completion, in some embodiments of this application, the first control unit includes a fifth control module, a sixth control module, a seventh control module, and a first transmitting module. Specifically, the fifth control module controls all generator sets to disconnect their generator excitation when the generator sets meet the preset lubrication conditions, the engine coolant temperature is within the preset temperature range, and multiple generator sets meet the parallel operation conditions; the sixth control module controls the circuit breakers of all generator sets to close when their generator excitation is disconnected; the seventh control module controls all generator sets to start simultaneously when their circuit breakers are closed; and the first transmitting module simultaneously sends a first excitation signal to each generator set when the engine speed of all generator sets reaches a preset load-bearing speed, thus completing the parallel operation of multiple generator sets.

[0097] Through precise control and synchronized operation, efficient parallel operation of multiple generator sets was achieved while meeting preset lubrication conditions, engine coolant temperature standards, and parallel operation requirements. Specifically, once it is confirmed that all generator sets have reached ideal lubrication conditions, engine coolant temperatures are within suitable operating ranges, and electrical parameters meet parallel operation requirements, the generator excitation of each generator set is first disconnected uniformly. Then, the circuit breaker is quickly closed to create electrical connectivity for parallel operation. Next, all generator sets start synchronously under a unified command, ensuring no delay and avoiding electrical interference caused by asynchronous starting sequences during parallel operation. After all generator sets' engines are running stably and have reached preset load-bearing speeds, excitation signals are synchronously sent to each generator set to quickly establish a stable voltage output, achieving rapid parallel operation of multiple generator sets. This parallel operation strategy shortens the time from generator set startup to parallel operation completion, improves the response speed of power supply, and ensures the safety and stability of the parallel operation process.

[0098] In some embodiments of this application, the above-mentioned device further includes a monitoring unit and a second control unit. The monitoring unit monitors the rotational speed of each generator set. If, within the static parallel delay period, the rotational speed of any generator set fails to reach the preset load-bearing speed, the unit is determined to have started abnormally and is identified as a faulty generator set. The second control unit controls the faulty generator set to exit the static parallel mode and enter the dynamic parallel mode. The static parallel delay period is the time interval from the closing of the circuit breakers of all generator sets to the simultaneous transmission of the first excitation signal to each generator set.

[0099] By continuously monitoring the rotational speed and promptly handling anomalies, overall parallel operation failures caused by the starting failure or malfunction of individual generator sets are effectively prevented. This not only enhances the flexibility and fault tolerance of parallel operation but also ensures the stability and reliability of the entire power supply system. Even in the face of sudden faults, it can react quickly to avoid adverse impacts on power demand. Furthermore, the automatic switching mechanism of the dynamic parallel mode can minimize the impact of fault handling on parallel operation time, ensuring the continuity and high quality of power supply.

[0100] Furthermore, the second control unit includes a tripping module and a second transmitting module. The tripping module is used to perform a tripping operation on the circuit breaker of the faulty generator set to isolate it; the second transmitting module is used to send a second excitation signal to the faulty generator set, causing it to enter the dynamic parallel connection mode.

[0101] In dynamic parallel operation mode, the faulty generator set will independently start its excitation system, establish a stable voltage output, and then monitor its electrical parameters (including voltage, frequency, and phase) until the parallel operation conditions are met. Then, it will search for a synchronization point with the grid or existing paralleled units, execute a closing operation, and thus reconnect to the system. Unlike the direct synchronous closing in static parallel operation mode, dynamic parallel operation mode gives the faulty generator set more time and conditions to adjust its state until it meets the parallel operation criteria. This not only improves the success rate of parallel operation but also ensures the overall performance and safety of the power system. Through this mechanism, the efficiency and reliability of generator parallel operation are ensured. Even in the face of sudden failures of one or more generator sets, the faulty unit can be quickly switched to dynamic parallel operation mode to prevent the fault from spreading, while giving the faulty unit a chance to recover, ensuring the continuity and quality of power supply.

[0102] In some embodiments of this application, the execution unit includes a holding module and an adjustment module. The holding module is used to maintain the engine coolant temperature within the preset temperature range using a forced-type water jacket heater during the oil pre-supply operation. The adjustment module is used to adjust the operating mode of the forced-type water jacket heater according to the real-time ambient temperature.

[0103] By simultaneously implementing engine coolant temperature control during oil pre-supply, a comprehensive and highly efficient pre-start management mechanism is established. This mechanism adapts to various environmental conditions, ensuring rapid and safe engine start-up under any circumstances, providing a solid foundation for the high-performance operation of the generator set. The use of a forced-type water jacket heater during the generator set's pre-start phase enables precise management and regulation of the engine coolant temperature, ensuring it remains within the preset optimal temperature range. This strategy not only provides effective engine preheating during oil pre-supply, protecting it from damage caused by cold starts, but also dynamically adjusts the heater's operating mode by intelligently sensing changes in ambient temperature, providing the most suitable hot-state start-up conditions for the engine regardless of extreme cold or heat. Engine starting efficiency and reliability are significantly improved, while energy consumption and mechanical wear during the start-up process are reduced, extending equipment lifespan.
