[0030] In this embodiment, a response control method for a generator set running on a mobile terminal, a computer terminal or a similar computing device is provided. 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 shown here.
[0031] Figure 2 FIG. 1 is a flow chart of a response control method for a generator set according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:
[0032] Step S201: When the generator set is in a standby state, an oil pre-supply operation is performed to meet a preset lubrication condition. During the execution of the oil pre-supply operation, the engine water temperature is monitored and controlled to be 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 operating. The preset lubrication condition includes the oil pressure reaching a preset standard.
[0033] Specifically, when the generator set is in standby mode, oil pre-supply is performed. Its purpose is to pre-supply oil before startup to achieve preset lubrication conditions. Pre-set lubrication conditions refer to oil pressure reaching a preset standard, ensuring adequate 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 during the initial generator set power-up phase but also from the end of each generator run until the next startup. This creates a cyclic pre-supply mechanism that continuously maintains lubrication within the engine and improves startup efficiency.
[0034] In order to further optimize the engine's starting performance, engine water temperature preheating and control are introduced to ensure that the engine water temperature is maintained within the preset temperature range. This way, the engine can be in a warm-up state when started at any time, reducing the negative effects of cold starts, such as increased wear and fuel consumption.
[0035] The oil pre-supply operation and engine water temperature monitoring strategy implemented during the generator set's standby period significantly enhances the generator set's rapid start-up capability and operational reliability. By periodically pre-supplying oil at the initial stage of the generator set's power-up and after operation, it ensures that the engine is always in a fully lubricated state, effectively preventing mechanical damage caused by insufficient lubrication during startup and extending the engine's service life. At the same time, the monitoring of the engine water temperature allows the engine water temperature to be maintained in the optimal preheating range, quickly reaching the operating temperature even in low-temperature environments, further improving starting efficiency and operating performance. The dual protection of oil pre-supply and water 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 emergency situations or high load demands, and can quickly provide stable power.
[0036] Step S202, when the above-mentioned generator sets meet the above-mentioned preset lubrication conditions, the above-mentioned engine water temperature is within the above-mentioned preset temperature range, and the multiple generator sets meet the parallel conditions, control the multiple generator sets to be paralleled, and the above-mentioned parallel 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 parallel connection of multiple generator sets. If the system busbar has voltage or other generator sets have been closed, the speed and voltage of the generator set need to be controlled. When the voltage, frequency, and phase of the generator set are consistent with the busbar, the generator set sends a closing signal to connect the generator set to the busbar. When multiple generator sets need to be operated in parallel, that is, multiple generator sets meet the parallel operation conditions, specifically, in addition to ensuring that each generator set has met the above-mentioned preset lubrication conditions and preheating requirements, the total load demand also needs to be evaluated. If the total load demand exceeds the rated output power of a single generator set, this means that multiple generator sets need to be operated in parallel to share the load and ensure the stability and adequacy of the power supply.
[0038] Through the above control method, the generator set can always maintain a good start-up readiness state in the standby state, and the parallel operation is efficiently executed when multiple generator sets meet the necessary conditions, ensuring that the 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] Through this embodiment, when a 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 water temperature is monitored and controlled within a preset temperature range. The oil pre-supply operation includes pre-supplying oil during the initial power-up phase of the generator set and after the generator set has completed operation. The preset lubrication conditions include the oil pressure reaching a preset standard. When the generator set meets the preset lubrication conditions, the engine water temperature is within the preset temperature range, and multiple generator sets meet the paralleling conditions, the multiple generator sets are controlled to be paralleled. The paralleling conditions include the total load demand being greater than the rated output power of a single generator set. In this solution, the oil pre-supply operation is performed and the engine water temperature is monitored in the standby mode to ensure that the generator set is always in the optimal pre-lubrication and preheating state, thereby accelerating startup and reducing mechanical wear in the initial startup phase, achieving rapid power generation. When multiple generator sets need to be operated in parallel, the multiple generator sets are controlled to be paralleled, enabling startup and paralleling to be completed in a very short time, thereby resolving the problem of long generator set response time in the prior art.
[0040] During 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 above-mentioned generator set is powered on, controlling the oil pre-supply to last for a first preset time; after the above-mentioned generator set ends and before it is started again, controlling the above-mentioned oil pre-supply to last for the above-mentioned first preset time every second preset time, wherein, when the start-up command of the above-mentioned generator set is received, the above-mentioned oil pre-supply operation is interrupted.
[0041] Specifically, after the generator set is powered on, the oil pump is controlled to begin pre-supplying oil. This process lasts for a first preset time, which in this embodiment can be 60 seconds. Activating the oil pump quickly establishes oil circulation, delivering lubricant to key engine components such as the pistons, crankshaft, and connecting rod bearings, thereby 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 has finished operating and before its next start, it enters a maintenance cycle. During this cycle, the engine oil pre-supply operation is performed every second preset time (in this embodiment, the second preset time can be set to 48 hours) for the same first preset time (for example, 60 seconds). This cyclic pre-supply mechanism ensures that the engine remains well lubricated and ready to respond to the start command even during long periods of standby. This pre-supply not only reduces startup delays but also reduces 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 is immediately interrupted to ensure the generator set can quickly respond to the start request. This mechanism prioritizes generator set start-up efficiency, avoids conflicts between pre-supply operations and the start-up process, and ensures that the generator set can start supplying power without delay in emergency situations or situations requiring a quick response.
[0044] The oil pre-supply mechanism in the generator set's standby state ensures adequate lubrication and rapid response before engine start-up. When the generator set is powered on, an oil pre-supply operation is performed for a period of time to ensure that all engine components are pre-lubricated, effectively preventing dry friction during the initial start-up period and reducing engine wear. In addition, the generator set restarts the oil pre-supply at a set time interval after the end of each run and during the standby period before the next start-up. This cyclic pre-supply process further ensures that the engine is in the optimal lubrication state when started at any time, shortens the time from the issuance of the start command to the actual start-up, and improves the starting efficiency of the generator set. When the generator set receives the start command, the ongoing oil pre-supply operation is immediately interrupted to ensure that the generator set can quickly respond to the start-up demand and provide timely power support. This not only significantly improves the starting speed of the generator set, but also extends the service life of the engine and reduces maintenance costs.
[0045] In some embodiments of the present application, when the generator set is in standby mode, an oil pre-supply operation is performed to meet preset lubrication conditions, and the process also includes: while performing the above-mentioned oil pre-supply operation, collecting the above-mentioned oil pressure at a preset time to obtain an oil pressure value; when the above-mentioned oil pressure value is greater than or equal to the preset value, controlling the above-mentioned generator set to start normally; when the above-mentioned oil pressure value is less than the above-mentioned preset value, controlling the above-mentioned generator set to stop running, and triggering an oil pre-supply circuit fault warning.
[0046] Specifically, during the oil pre-feed process, the oil pressure value is acquired at a preset time. That is, during the oil pre-feed process, the ECU (Electronic Control Unit) is powered on, the oil pre-feed continues for 60 seconds, and the oil pressure is acquired at the 57th second (the preset time). This real-time monitoring step accurately reflects the operating status of the engine lubrication system and provides objective data to determine whether the oil pre-feed is achieving the desired effect.
[0047] The collected oil pressure directly determines whether the generator set can start normally. If the oil pressure is greater than or equal to the preset value, it indicates that a lubricating oil film has formed inside the engine, ensuring safe lubrication conditions for starting. At this point, the generator set will be allowed to start according to normal procedures, ensuring smooth engine operation and effectively preventing damage 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 falls below the preset value, this indicates a fault in the oil pre-supply circuit and the lubrication system is not functioning properly. In this case, protective measures are immediately implemented to prevent the generator set from starting, preventing serious engine damage from forced startup under low lubrication conditions. Simultaneously, an oil pre-supply circuit fault warning is triggered, alerting the operator to inspect and correct the lubrication system issue, ensuring safety and reliability upon restart after troubleshooting. This warning is latched and recorded in the warning log. The warning display can only be reset by pressing the emergency stop or mute button, effectively ensuring operator confirmation of the warning.
[0049] By monitoring oil pressure in real time during the oil pre-supply operation and using this as a basis for generator set start-up decisions, the system effectively manages and protects engine lubrication conditions. While the generator set is in standby mode, oil pre-supply is performed, and oil pressure is collected at predetermined critical moments. If the oil pressure reaches or exceeds a preset safety level, indicating adequate lubrication within the engine, the generator set is allowed to start according to normal procedures, ensuring smooth engine operation and extending its service life. However, if the oil pressure detected after the pre-supply operation falls below the preset level, indicating insufficient lubrication system efficiency or other related malfunctions, the generator set is prevented from starting to prevent potential engine damage. An oil pre-supply circuit fault warning is immediately triggered, alerting the operator to inspect and repair the problem until the lubrication issue is resolved. This improves generator set start-up safety, avoids the risks of starting without adequate lubrication, and ensures high equipment efficiency and stability, providing a more reliable and secure power supply.
[0050] During the generator set's standby state, in addition to implementing oil pre-supply and water temperature control, an intelligent pre-start mechanism can be introduced. This mechanism, combined with advanced load forecasting algorithms, predicts future changes in power demand. Using real-time data collected through the network or sensors, such as weather forecasts, power consumption history, and current grid status, the intelligent pre-start mechanism can anticipate periods of likely high load demand. If it is predicted that future loads may exceed the handling capacity of a single generator set, the pre-start steps for multiple generator sets, including oil pre-supply and engine preheating, are activated in advance, rather than just after receiving the start command. This ensures that the generator sets are 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] In order to shorten the time from the start-up of the generator set to the completion of parallel operation, in some embodiments of the present application, when the above-mentioned generator set meets the above-mentioned preset lubrication conditions, the above-mentioned engine water temperature is within the above-mentioned preset temperature range, and multiple above-mentioned generator sets meet the parallel operation conditions, multiple above-mentioned generator sets are controlled to be paralleled, including: when the above-mentioned generator set meets the above-mentioned preset lubrication conditions, the above-mentioned engine water temperature is within the above-mentioned preset temperature range, and multiple above-mentioned generator sets meet the above-mentioned parallel operation conditions, all above-mentioned generator sets are controlled to disconnect the generator excitation; when all above-mentioned generator sets disconnect the generator excitation, the circuit breakers of all above-mentioned generator sets are controlled to be closed; when the circuit breakers of all above-mentioned generator sets are closed, all above-mentioned generator sets are controlled to start simultaneously; when the engine speed of all above-mentioned generator sets reaches the preset load speed, the first excitation signal is sent to each above-mentioned generator set at the same time to complete the parallel operation of multiple above-mentioned generator sets.
[0052] Specifically, before commencing parallel operations, each generator set is thoroughly inspected to ensure it meets pre-set lubrication requirements, engine water temperature is within the pre-set temperature range, and all other paralleling requirements are met. This pre-set lubrication condition check ensures that all engines are adequately pre-lubricated before paralleling, preventing potential damage during startup. Monitoring engine water temperature ensures that the engines start at the appropriate temperature, improving startup efficiency and reducing warm-up time. Verifying paralleling requirements includes ensuring the consistency of electrical parameters (such as voltage, frequency, and phase) to ensure smooth, synchronized parallel operation of all generator sets.
[0053] After all the above conditions are met, the excitation of all generators to be paralleled is first disconnected. This disconnection prepares for the paralleling operation and prevents electrical problems caused by unstable excitation during the paralleling process. Subsequently, with the excitation disconnected, the circuit breakers of all generators are closed. This step connects the output ports of each generator set to the load or busbar, preparing for the next step of synchronized starting. After the circuit breakers are closed, all generator sets are immediately started simultaneously. Synchronous starting ensures that the engines of each generator set reach the operating state at the same time, reducing paralleling difficulties caused by asynchronous start sequences and further improving paralleling efficiency. When the engine speeds of all generator sets stabilize and reach the preset load speed, the first excitation signal is sent to each generator set simultaneously. This synchronized transmission of the first excitation signal enables each generator set to establish a stable output voltage simultaneously, completing the parallel operation and providing a unified power supply. This strategy avoids the paralleling delays and power fluctuations caused by the time difference in excitation establishment in traditional paralleling methods, ensuring a fast and smooth paralleling process.
[0054] By systematically controlling the pre-lubrication status, engine water temperature, excitation disconnection, and synchronous start-up of the generator sets, a fast and efficient paralleling strategy is implemented. This strategy not only significantly shortens paralleling time and improves the responsiveness of the power supply system, but also ensures electrical safety and stability during the paralleling process. It is suitable for applications requiring the combined power supply of multiple generator sets, such as large data centers, industrial facilities, or power system emergency response, significantly improving the reliability and efficiency of power supply.
[0055] The above paralleling process, through precise control and synchronization, enables efficient paralleling of multiple generator sets while meeting preset lubrication conditions, engine water temperature standards, and paralleling requirements. Specifically, once all generator sets have been confirmed to be ideally lubricated, engine water temperatures are within the appropriate operating range, and electrical parameters meet paralleling requirements, the generator excitations for each generator set are first disconnected, followed by rapid closing of the circuit breakers to establish electrical connectivity for paralleling. Next, all generator sets are started simultaneously under unified command, ensuring no delays and avoiding electrical interference caused by asynchronous start sequences during the paralleling process. After all generator sets have stabilized and reached the preset load speed, excitation signals are synchronously transmitted to each generator set, rapidly establishing stable voltage output and enabling rapid paralleling of multiple generator sets. This paralleling strategy shortens the time from generator set start-up to paralleling completion, improving power supply responsiveness while ensuring the safety and stability of the paralleling process.
[0056] In some embodiments of the present application, the above method also includes: monitoring the rotational speed of each of the above-mentioned generator sets, and if the rotational speed of any of the above-mentioned generator sets does not reach the preset load speed within the static parallel delay time period, determining that the startup of the above-mentioned generator sets is abnormal, and determining the above-mentioned generator sets as faulty generator sets; controlling the above-mentioned faulty generator sets to exit the static parallel mode and enter the dynamic parallel mode, wherein the above-mentioned static parallel delay time period is the time interval from the closing of the circuit breakers of all the above-mentioned generator sets to the simultaneous sending of the first excitation signal to each of the above-mentioned generator sets.
[0057] Specifically, in the static parallel mode, that is, the stage where the circuit breakers of the above-mentioned generator sets are closed first and then all the generator sets are started synchronously, the real-time speed of each generator set is continuously monitored to verify whether it can accelerate to the preset load speed as expected. This monitoring process runs through the entire static parallel delay period, that 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 it is found that the speed of any generator set cannot reach the preset load speed during the static parallel delay period, the generator set is judged to have a startup abnormality and is determined to be a faulty generator set. Once a generator set is determined to be a faulty generator set, in order not to affect the entire paralleling process, measures will be taken immediately to remove it from the static parallel mode and change it to the dynamic parallel mode.
[0058] Continuous speed monitoring and timely exception handling effectively prevents overall parallel failures caused by individual generator set startup failures or anomalies. This not only enhances the flexibility and fault tolerance of parallel operations but also ensures the stability and reliability of the entire power supply system. Even in the face of sudden faults, a swift response can be made to avoid adverse impacts on power demand. Furthermore, the automatic switching mechanism in dynamic parallel mode minimizes the impact of fault handling on paralleling time, ensuring the continuity and quality of power supply.
[0059] Furthermore, controlling the above-mentioned faulty generator set to exit the static parallel mode and enter the dynamic parallel mode includes: performing a tripping operation on the circuit breaker of the above-mentioned faulty generator set to isolate the above-mentioned faulty generator set; sending a second excitation signal to the above-mentioned faulty generator set, and the above-mentioned faulty generator set entering the above-mentioned dynamic parallel mode.
[0060] Specifically, the faulty generator set's circuit breaker is first opened. This disconnects the faulty generator set's output from the grid or load, effectively isolating the unit and preventing its unstable state from interfering with or damaging the parallel operation of other normally operating generator sets or the entire power system. Rapid circuit breaker opening ensures timely and safe 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, different from the first excitation signal in static parallel mode, instructs the faulty generator set to enter dynamic parallel mode. In dynamic parallel mode, the faulty generator set independently starts its excitation system to establish a stable voltage output. It then monitors its electrical parameters (including voltage, frequency, and phase) until parallel conditions are met. It then seeks synchronization with the grid or existing paralleled units and performs a closing operation to rejoin the system. Unlike the static parallel mode, which directly closes the circuit breaker synchronously, the dynamic parallel mode gives the faulty generator set more time and conditions to adjust its own status until the paralleling standard is met. This not only improves the success rate of the parallel operation, but also ensures the overall performance and safety of the power system.
[0061] The above mechanism ensures the high efficiency and reliability of generator set parallel operation. Even in the face of sudden failure of a single or multiple generator sets, the faulty units can be quickly switched to dynamic parallel mode to avoid the spread of the fault. At the same time, the faulty units are given a chance to recover, ensuring the continuity and quality of power supply.
[0062] In some embodiments of the present application, during the execution of the above-mentioned oil pre-supply operation, the engine water temperature is monitored and controlled within a preset temperature range, including: during the execution of the above-mentioned oil pre-supply operation, using a forced water jacket heater to maintain the above-mentioned engine water temperature within the above-mentioned preset temperature range; and adjusting the working mode of the above-mentioned forced 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), the forced water jacket heater is activated to maintain the engine coolant temperature within a preset range. A forced water jacket heater is a device specifically designed to control engine coolant temperature. It consists of a water pump, 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 ambient temperature and dynamically adjusts the operating mode of the forced-water jacket heater based on this real-time data. This means that in cold environments, the forced-water jacket heater will increase heating power to offset the low temperature and ensure that the engine water temperature does not drop too low. In warm or hot environments, the forced-water jacket heater will reduce heating or stop heating completely to prevent engine overheating. In this way, the system can adapt to various external conditions and always maintain the engine water temperature within a predetermined temperature range that is conducive to rapid starting and operation.
[0065] By simultaneously controlling engine water temperature during the oil pre-supply process, a comprehensive, highly efficient pre-start management mechanism is established. This mechanism adapts to diverse environmental conditions, ensuring rapid and safe engine starts in all circumstances and providing a solid foundation for high-performance generator set operation. By utilizing a forced-type jacket water heater during the generator set pre-start phase, precise engine water temperature management and regulation are achieved, ensuring it remains within the preset optimal temperature range. This strategy not only effectively preheats the engine during the oil pre-supply process, preventing damage from cold starts, but also intelligently senses changes in ambient temperature and dynamically adjusts the heater's operating mode, ensuring optimal hot start conditions for the engine, regardless of extreme cold or heat. This significantly improves engine starting efficiency and reliability, while also reducing energy consumption and mechanical wear during the startup process and extending equipment life. This approach ensures rapid power supply in critical situations while maintaining long-term system stability and cost-effectiveness, demonstrating a dual focus on generator set maintenance and efficiency improvement.
[0066] 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 response control method of the generator set of the present 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. Figure 3 shown.
[0068] 1. When the generator set is in standby mode, the circulating oil is pre-supplied according to the set detection time to keep the generator set in a lubricated state.
[0069] Oil pre-supply logic description:
[0070] See also Figure 3 After the generator set is powered on, regardless of the controller's control mode, the controller will control the oil pre-supply for 60 seconds, effectively preventing operators from forgetting to pump oil before starting the generator set. After the initial oil pre-supply is completed or the generator set has finished running, when the generator set controller is powered on (regardless of the operating mode), the generator set will execute the 48-hour 60-second pre-supply logic (the interval and pre-supply time are adjustable). The oil pre-supply can be interrupted by an emergency stop, and the unit startup will also interrupt the oil pre-supply, ensuring the unit startup priority.
[0071] During the oil pre-supply process, the ECU is powered on at the same time. The oil is pre-supplied for 60 seconds. The oil pressure is collected at the 57th second. If the oil pressure does not reach 0.3Bar (the judgment value is adjustable), it is judged that the oil pre-supply pressure is insufficient, the generator set is shut down, and the generator set controller will have an early warning of oil pre-supply circuit failure. The early warning information is latched and recorded in the early warning record. The display of the early warning information can only be reset by the emergency stop or mute button, which effectively ensures that the operator confirms this early 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 at 25-40°C to ensure that the engine is always in a hot state.
[0073] A forced-type jacket water heater consists of a water pump, heating element, and intelligent temperature control system. When installed, the coolant in an engine is circulated between the heated 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 performance, reduces starting losses, minimizes engine wear, and saves fuel.
[0074] To further improve generator set startup efficiency and reduce energy consumption, an adaptive oil pre-feed and water temperature control strategy has been introduced. This strategy dynamically adjusts based on current engine temperature, oil viscosity, ambient conditions, and the generator set's usage history. For example, if the engine temperature is already high or the oil viscosity is low, the oil pre-feed time is reduced. However, in cold environments or when the generator set has not been used for a long time, the pre-feed time and heater power are increased. Furthermore, the pre-feed interval and heater operating mode are automatically adjusted based on the generator set's start frequency and operating time to achieve optimal maintenance results and energy efficiency. This adaptive control strategy not only significantly improves generator set startup speed, but also reduces unnecessary energy consumption, optimizes maintenance schedules, and thus reduces operating costs and enhances overall system performance.
[0075] 3. Instructions for using static parallel connection:
[0076] The controller software has the following capabilities:
[0077] Generator three-phase voltage acquisition, load three-phase current acquisition, sensor data acquisition, input port detection, output port control, data alarm processing, key detection, LED status indication, history recording, controller mode selection, VFD display, speed acquisition, communication control, speed regulation, voltage regulation, multi-machine communication, unit parallel power distribution, mains / busbar three-phase voltage acquisition.
[0078] The controller software realizes the automatic start-up, shutdown, closing and opening of the diesel generator set and complete fault display and protection functions, and realizes the power equalization and parallel operation of multiple units.
[0079] Static parallel logic:
[0080] In scenarios where rapid parallel connection is required, the generator set circuit breakers must be closed before generating electricity. The operating logic is as follows: all generator sets are de-excited, the generator set circuit breakers are closed first, and then the generator sets are started simultaneously. When all engine speeds reach the load speed, the excitation signal is simultaneously issued, the generator voltage is established, and the generator set parallel connection is completed.
[0081] If a unit fails to meet the output excitation conditions within the set static parallel delay time, it exits static parallel mode and switches to dynamic parallel mode. The operating logic is: the generator set circuit breaker is first opened, the generator excitation is output, and the generator is closed after the synchronization conditions are met. After static parallel failure, restarting, speed increase, voltage buildup, and parallel closing are allowed without affecting the normal operation of other units.
[0082] The static parallel connection solution saves the time required for the units to wait for synchronization conditions to be met before closing the generator during ordinary parallel connection, thereby increasing the power supply speed.
[0083] This application provides a systematic solution to issues that affect the pre-lubrication, preheating, and parallel connection mode after the generator set is started, thereby maximizing the performance of the generator set.
[0084] In some application scenarios that require a fast power supply response, such as data centers and emergency start-up scenarios, the engine needs to be in a hot standby and lubricated state at all times. Through the set pre-lubrication and water heating system, the generator set can be started faster, reducing engine wear and achieving rapid power generation.
[0085] The traditional paralleling mode is dynamic paralleling, where the generator sets generate power first and then close at the synchronization point. Once the generator sets are started and generating normally, if the system busbar has no voltage signal, a closing status flag is first sent to the remaining units to be paralleled. The generator closing relay then activates to prevent other units from closing at the same time. If the system busbar has voltage or other units are already closed, the controller will control the GOV speed and AVR voltage to synchronize the units with the busbar. When synchronization conditions are met, a closing signal is issued to connect the units to the busbar. Once the units are connected to the busbar, the controller gradually increases the engine throttle to share the load with the other paralleled units. Using dynamic paralleling, the generator set takes 60-90 seconds from receiving the start command to closing and supplying power. By applying static paralleling technology, the units can be started within 10 seconds and paralleled within 11-15 seconds, improving power supply speed.
[0086] The embodiment of the present application also provides a response control device for a generator set. It should be noted that the response control device for a generator set in the embodiment of the present application can be used to execute the response control method for a generator set provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation methods, and the details that have been explained will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation in hardware, or a combination of software and hardware, is also possible and conceivable.
[0087] The following introduces the response control device of the generator set provided in the embodiment of the present application.
[0088] Figure 4 Schematic diagram of a response control device for a generator set according to an embodiment of the present application. Figure 4 As shown, the device includes an execution unit 10 and a first control unit 20 .
[0089] The execution unit is configured to perform an oil pre-supply operation to meet a preset lubrication condition when the generator set is in a standby state, and monitor and control the engine water temperature within a preset temperature range during the execution of the oil pre-supply operation. 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 operating. The preset lubrication condition includes the oil pressure reaching a preset standard.
[0090] The first control unit is used to control the plurality of generator sets to be paralleled when the generator sets meet the preset lubrication conditions, the engine water temperature is within the preset temperature range, and the plurality of generator sets meet the paralleling conditions, wherein the paralleling conditions include a total load demand greater than the rated output power of a single generator set.
[0091] In standby mode, the system performs oil pre-supply operations and monitors engine water temperature to ensure that the generator set is always in the optimal pre-lubrication and preheating state, thereby accelerating startup and reducing mechanical wear in the initial startup phase, achieving rapid power generation. When multiple generator sets need to be run in parallel, the system controls multiple generator sets for parallel operation, enabling startup and parallel operation to be completed in a very short time, thus solving the problem of long response time of generator sets in the existing technology.
[0092] In a specific implementation, the execution unit includes a first control module and a second control module. The first control module is configured to control the oil pre-supply to continue for a first preset time after the generator set is powered on; the second control module is configured to control the oil pre-supply to continue for the first preset time every second preset time after the generator set ends and before it is restarted. The oil pre-supply operation is interrupted upon receiving a start command for the generator set.
[0093] The oil pre-supply mechanism in the generator set's standby state ensures adequate lubrication and rapid response before engine start-up. When the generator set is powered on, an oil pre-supply operation is performed for a period of time to ensure that all engine components are pre-lubricated, effectively preventing dry friction during the initial start-up period and reducing engine wear. In addition, the generator set restarts the oil pre-supply at a set time interval after the end of each run and during the standby period before the next start-up. This cyclic pre-supply process further ensures that the engine is in the optimal lubrication state when started at any time, shortens the time from the issuance of the start command to the actual start-up, and improves the starting efficiency of the generator set. When the generator set receives the start command, the ongoing oil pre-supply operation is immediately interrupted to ensure that the generator set can quickly respond to the start-up demand and provide timely power support. This not only significantly improves the starting speed of the generator set, but also extends the service life of the engine and reduces maintenance costs.
[0094] In some embodiments of the present application, the execution unit further includes a collection module, a third control module, and a fourth control module. The collection module is configured to collect the oil pressure at a preset time while executing the oil pre-supply operation to obtain an oil pressure value; the third control module is configured to control the generator set to start normally if the oil pressure value is greater than or equal to the preset value; and the fourth control module is configured to control the generator set to stop operating and trigger an oil pre-supply circuit fault warning if 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 a basis for generator set start-up decisions, the system effectively manages and protects engine lubrication conditions. While the generator set is in standby mode, oil pre-supply is performed, and oil pressure is collected at predetermined critical moments. If the oil pressure reaches or exceeds a preset safety level, indicating adequate lubrication within the engine, the generator set is allowed to start according to normal procedures, ensuring smooth engine operation and extending its service life. However, if the oil pressure detected after the pre-supply operation falls below the preset level, indicating insufficient lubrication system efficiency or other related malfunctions, the generator set is prevented from starting to prevent potential engine damage. An oil pre-supply circuit fault warning is immediately triggered, alerting the operator to inspect and repair the problem until the lubrication issue is resolved. This improves generator set start-up safety, avoids the risks of starting without adequate lubrication, and ensures high equipment efficiency and stability, providing a more reliable and secure power supply.
[0096] In order to shorten the time from generator set startup to paralleling completion, in some embodiments of the present application, the first control unit includes a fifth control module, a sixth control module, a seventh control module, and a first sending module. The fifth control module is configured to control all of the generator sets to disconnect the generator excitation when the generator sets meet the preset lubrication conditions, the engine water temperature is within the preset temperature range, and multiple generator sets meet the paralleling conditions; the sixth control module is configured to control all of the generator sets to close the circuit breakers when all of the generator sets disconnect the generator excitation; the seventh control module is configured to control all of the generator sets to start simultaneously when the circuit breakers of all of the generator sets are closed; and the first sending module is configured to simultaneously send a first excitation signal to each of the generator sets when the engine speed of all of the generator sets reaches the preset load speed, thereby completing the paralleling operation of the multiple generator sets.
[0097] Through precise control and synchronized operation, efficient paralleling of multiple generator sets is achieved while meeting preset lubrication conditions, engine water temperature standards, and paralleling requirements. Specifically, once all generator sets have been confirmed to have achieved ideal lubrication conditions, engine water temperatures are within the appropriate operating range, and electrical parameters meet paralleling requirements, the generator excitations of each generator set are first disconnected, followed by the rapid closing of the circuit breakers to establish electrical connectivity for paralleling. Next, all generator sets are started simultaneously under unified command, ensuring no delays, thus avoiding electrical interference caused by asynchronous start sequences during the paralleling process. After all generator sets' engines have stabilized and reached the preset load speed, excitation signals are synchronously sent to each generator set, quickly establishing stable voltage output and enabling rapid paralleling of multiple generator sets. This paralleling strategy shortens the time from generator set start-up to paralleling completion, improving the responsiveness of power supply while ensuring the safety and stability of the paralleling process.
[0098] In some embodiments of the present application, the apparatus further includes a monitoring unit and a second control unit. The monitoring unit is configured to monitor the rotational speed of each of the generator sets. If the rotational speed of any of the generator sets does not reach a preset load rotational speed within the static parallel delay period, the generator set startup is determined to be abnormal and the generator set is identified as a faulty generator set. The second control unit is configured to control the faulty generator set to exit the static parallel mode and enter the dynamic parallel mode, wherein the static parallel delay period is the time interval from closing the circuit breakers of all the generator sets to simultaneously sending the first excitation signal to each of the generator sets.
[0099] Continuous speed monitoring and timely exception handling effectively prevents overall parallel failures caused by individual generator set startup failures or anomalies. This not only enhances the flexibility and fault tolerance of parallel operations but also ensures the stability and reliability of the entire power supply system. Even in the face of sudden faults, a swift response can be made to avoid adverse impacts on power demand. Furthermore, the automatic switching mechanism in dynamic parallel mode minimizes the impact of fault handling on paralleling time, ensuring the continuity and quality of power supply.
[0100] Furthermore, the second control unit includes a tripping module and a second sending module. The tripping module is used to perform a tripping operation on the circuit breaker of the faulty generator set to isolate the faulty generator set; the second sending module is used to send a second excitation signal to the faulty generator set, so that the faulty generator set enters the dynamic parallel mode.
[0101] In dynamic parallel mode, the faulty generator set will independently start its excitation system to establish a stable voltage output, then monitor its electrical parameters (including voltage, frequency, and phase) until the paralleling conditions are met. It will then re-seek synchronization with the grid or the paralleled generator set, execute the closing operation, and re-join the system. Unlike the direct synchronous closing in static parallel mode, dynamic parallel mode gives the faulty generator set more time and conditions to adjust its status until it meets the paralleling standards. This not only improves the success rate of paralleling operations, but also ensures the overall performance and safety of the power system. This mechanism ensures the efficiency and reliability of generator set paralleling. Even in the face of sudden failures in one or more generator sets, the faulty generator set can be quickly switched to dynamic parallel mode to prevent the fault from spreading, while giving the faulty generator set an opportunity to recover and ensure the continuity and quality of power supply.
[0102] In some embodiments of the present application, the execution unit includes a maintaining module and an adjusting module. The maintaining module is configured to maintain the engine water temperature within the preset temperature range using a forced water jacket heater during the oil pre-supply operation, and the adjusting module is configured to adjust the operating mode of the forced water jacket heater according to the real-time ambient temperature.
[0103] By simultaneously controlling engine water temperature during the oil pre-supply process, a comprehensive, highly efficient pre-start management mechanism is established. This mechanism adapts to diverse environmental conditions, ensuring rapid and safe engine starts in all circumstances and providing a solid foundation for high-performance generator set operation. By utilizing a forced-type jacket water heater during the generator set pre-start phase, precise engine water temperature management and regulation are achieved, ensuring it remains within the preset optimal temperature range. This strategy not only effectively preheats the engine during the oil pre-supply process, preventing damage from cold starts, but also intelligently senses changes in ambient temperature and dynamically adjusts the heater's operating mode, ensuring optimal hot start conditions for the engine, regardless of extreme cold or heat. This significantly improves engine starting efficiency and reliability, while also reducing energy consumption and mechanical wear during the startup process and extending equipment life. This approach ensures rapid power supply in critical situations while maintaining long-term system stability and cost-effectiveness, demonstrating a dual focus on generator set maintenance and efficiency improvement.
