[0048] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The main solution of the embodiment of the present application is: when a start-up signal of a generator set device is received, a device start-up instruction is generated based on the target operating time of the generator set device; the start-up of the generator set device is controlled based on the device start-up instruction, and the workload and equipment environmental parameters of the generator set device during the startup process are obtained; a risk assessment of the generator set device is performed based on the workload, the equipment environmental parameters and the target operating time to obtain an assessment result; and the generator set device is managed according to the assessment result.

[0051] With the accelerated construction of new power systems, generator set equipment management faces multi-dimensional challenges. Existing solutions have technical shortcomings in meeting the requirements for coordinated multi-parameter control for rapid startup and shutdown. Traditional methods rely on independent parameter threshold monitoring (e.g., independent judgment of temperature, vibration, and pressure subsystems) and lack a dynamic collaborative model for multi-physics coupling. This results in a high rate of protective action triggering during startup due to parameter mismatches. Using a fixed threshold system, dynamic adjustment of parameter tolerances during startup and shutdown is impossible. For example, during a steam turbine cold start, a traditional distributed control system (DCS) only provides static temperature protection of ±10°C, resulting in actual startup times exceeding the standard 90-minute limit by more than 30%. Furthermore, the data exchange cycle between the DCS and the relay protection system is too long, making it difficult to support the real-time coordination required for rapid startup and shutdown. Furthermore, the separation of equipment protection (e.g., tripping due to excessive vibration limits) and operation optimization (e.g., calculation of minimum startup and shutdown times) into separate systems leads to conflicting decisions.

[0052] This application provides an equipment management method based on dynamic risk assessment and virtual-reality integration. Through real-time monitoring of multiple parameters, a hierarchical response mechanism, and abnormal annotation of virtual equipment models, it realizes precise and intelligent management of generator set equipment, effectively improving the safety and economy of equipment operation.

[0053] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, equipment monitoring, and program execution functions, such as a detection system, or an electronic device capable of implementing the above functions. The following uses the intelligent management and control system of a generator set as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the embodiment of the present application provides a device management method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the device management method of this application.

[0055] In this embodiment, the device management method includes:

[0056] Step S10: upon receiving a start-up signal of a generator set device, generating a device start-up instruction based on a target operating time of the generator set device.

[0057] It should be noted that the start signal refers to the command signal source that triggers the start of the generator set. The target operating time is the planned operating time of the generator set preset based on load demand or grid dispatch requirements. For example, in a peak-shaving scenario, the system will require the generator set to run for 2 hours to meet peak load demand. The device start instruction contains a set of control commands for the start parameter configuration. It is generated by the control system and sent to the corresponding device of the generator set. The instruction content usually includes the start mode, pre-lubrication time, speed ramp curve, and grid connection timing parameters.

[0058] It is understandable that the start signal may be derived from the detection result of main power supply voltage loss detection (such as the device voltage being lower than the power generation threshold), a manual operation instruction, or a remote control signal of the intelligent scheduling system, etc. This embodiment does not impose any limitation on this.

[0059] Furthermore, in order to optimize equipment operation time planning by acquiring load demand data in real time and combining it with equipment power characteristics, thereby avoiding energy waste or equipment loss due to excessive operation, and ensuring that the equipment operates efficiently while meeting load demand, step S10 may include:

[0060] When a start-up request of a generator set device is received, current load demand data of the generator set device is obtained; a target operating time is determined according to the load demand data and device power parameters; and a device start-up instruction is generated according to the target operating time.

[0061] It's important to note that load demand data refers to the real-time power load demand from the system or user before a generator set is started or during operation. This includes parameters such as total power required, peak power, and duration, reflecting the actual power demand the equipment must meet. Equipment power parameters, including rated power, operating efficiency, and energy efficiency, are key indicators of generator set performance and measure the power output capacity the equipment can provide per unit time.

[0062] It is understood that when a start request is received for a generator set, the system obtains the current load demand data in real time through a data interface or sensor. The load demand data can come from a power dispatch system, user-side power consumption data, or real-time monitoring data of a smart grid.

[0063] In one example, due to production needs, a power plant sends a generator set start-up request to the power system. By monitoring the operating status of the power plant's electrical equipment, the system determines that an additional 5,000 kW of electricity is currently required, with an estimated duration of 8 hours. The generator set in the power plant receives the start-up request, and the system calculates the target operating time required to be 5 hours based on the current grid load gap and equipment power parameters (a single unit has a rated power of 2,000 kW and an efficiency of 85%). The system encodes the target operating time into the equipment start-up instruction, which also includes parameters such as the equipment start-up time and initial power. The equipment start-up instruction is sent to the controller of the generator set equipment via wired or wireless communication. By calculating the target operating time in real time, the equipment only operates for the necessary time, avoiding over-operation or under-operation caused by fixed thresholds or manual experience.

[0064] Step S20: Control the generator set device to start based on the device start instruction, and obtain the workload and device environment parameters of the generator set device during the start-up process.

[0065] It's important to note that workload refers to the load borne by a generator set during operation. It typically includes real-time parameters such as output power, current, voltage, and speed, reflecting the actual operating status of the equipment. This can be used to assess whether the equipment's operating load is within a safe range and determine whether there are risks of overload or abnormal operation. Equipment environmental parameters are external environmental factors that affect equipment operation, including ambient temperature and humidity. Ambient temperature encompasses both the external and internal temperatures of the generator set.

[0066] It is understood that the system sends the generated device startup command to the generator set controller. The generator set controller interprets the command parameters (such as start time, target power, and run time), triggers the device startup process, and gradually increases the power to the target value as required, entering the startup state.

[0067] It should be understood that various sensors (such as temperature and humidity sensors, power transmitters, and speed sensors) are installed in key parts of the equipment (such as the generator stator, rotor, and bearings). These sensors collect real-time data on the equipment's workload and environmental parameters, and transmit them to the system through the data acquisition module.

[0068] It can be understood that obtaining the workload and equipment environmental parameters of the generator set equipment during the startup process can also build a digital twin model of the equipment, simulate the equipment operating status, optimize the equipment start and stop strategy through virtual simulation, and obtain data of the generator set equipment during the startup process.

[0069] Step S30 : performing a risk assessment on the generator set equipment based on the workload, the equipment environment parameters, and the target operating time to obtain an assessment result.

[0070] It should be noted that by analyzing real-time data on workload, environmental parameters, and target operating time, the safety and reliability of the generator set’s operating status can be evaluated, providing a basis for equipment management decisions and enabling preventive maintenance and fault avoidance.

[0071] It can be understood that when conducting a risk assessment of the generator set equipment based on the workload, the equipment environmental parameters and the target operating time, the real-time workload can be compared with a preset load threshold (such as 90% of the rated power) to determine whether it is overloaded; the environmental parameters can be compared with the equipment safety range to identify environmental risks; and the equipment operating time can be monitored to determine whether it is close to or exceeds the target operating time to determine whether there is a risk of overtime.

[0072] It's understandable that risk assessment can also employ a weighted scoring method or fuzzy logic algorithm, integrating the assessment results of three parameters: for example, workload with a 40% weight, environmental parameters with a 30% weight, and time constraints with a 30% weight. If the workload exceeds the limit, an emergency shutdown will be triggered even if other parameters are normal. Historical data can also be used to train models to predict changing trends in workload and environmental parameters.

[0073] Step S40: managing the generator set equipment according to the evaluation result.

[0074] It is understood that when an assessment result indicates an abnormality, the system will send a prompt message through the monitoring device to alert maintenance personnel that the equipment is potentially at risk but has not yet reached the emergency shutdown condition. If the assessment result indicates an emergency shutdown, the system immediately sends a command to the power control device to cut off the power supply to the equipment and shut it down. Different assessment results may lead to different subsequent decisions on the generator set equipment, and this embodiment does not limit this.

[0075] In this embodiment, upon receiving a start-up signal from a generator set, a device start-up instruction is generated based on the target operating time of the generator set; the generator set is started based on the device start-up instruction, and the workload and equipment environmental parameters of the generator set during the startup process are obtained; a risk assessment of the generator set is performed based on the workload, the equipment environmental parameters, and the target operating time, to obtain an assessment result; and the generator set is managed based on the assessment result. By real-time monitoring of the workload, environmental parameters, and target operating time of the generator set, and integrating operating time constraints, dynamic risk assessment and precise management of the equipment startup process are achieved, meeting the preventive safety control requirements during the generator set startup phase and effectively avoiding typical faults such as bearing overheating and winding insulation degradation caused by overtime operation.

[0076] Reference Figure 2, Figure 2 This is a flow chart of the second embodiment of the device management method of the present application. Based on the above-mentioned first embodiment, the second embodiment of the device management method of the present application is proposed.

[0077] In the second embodiment, step S30 includes:

[0078] Step S301: When the startup time of the generator set equipment is less than the target operating time, the workload is compared with a preset load threshold to obtain a first comparison result.

[0079] It should be noted that the startup time is the time it takes for the generator set to reach a stable operating state after receiving the start command. This can be used to determine whether the equipment has completed startup within a reasonable time. The load threshold is the preset upper limit of the equipment's safe operating load, which can be a percentage of the equipment's rated power.

[0080] It is understandable that overload is detected in the early or middle stage of the operation of the generator set equipment (start-up time is less than the target operating time) to avoid equipment damage due to long-term overload.

[0081] Specifically, when the startup time of the generator set equipment is less than the target operating time, that is, the equipment is still within the planned operating time period, a comparison between the workload and the load threshold is performed. If the workload is less than the load threshold, the first comparison result is "normal"; if the workload is greater than the load threshold, the first comparison result is "overload." The first comparison result needs to be combined with the environmental parameter comparison result (the second comparison result) to comprehensively determine whether the system protection condition is triggered and determine the equipment risk level of the current generator set equipment, such as normal startup, abnormal startup, emergency shutdown, etc.

[0082] Step S302: Compare each parameter in the device environment parameter with the corresponding preset environment threshold value to obtain a second comparison result.

[0083] It should be noted that preset environmental thresholds are safety intervals or critical values for environmental parameters, such as upper temperature limits, humidity ranges, and vibration amplitude limits, set in advance based on equipment design specifications and historical operating data. The second comparison result is a comprehensive assessment of the impact of environmental factors on equipment operation, derived by comparing each of the equipment's environmental parameters against the preset environmental thresholds. This assessment is used in conjunction with the workload comparison result (the first comparison result) to determine the equipment's risk level (e.g., normal, warning, or emergency shutdown).

[0084] Furthermore, in order to track the temperature change trend in real time by analyzing the correlation between the gradient descent rate calculation and the equipment parameters, and combine it with the dynamic matching of the humidity safety range, to provide early warning of the risk of equipment failure caused by sudden changes in ambient temperature or excessive humidity, the step S302 may include:

[0085] Determine a first ambient temperature, a second ambient temperature and an ambient humidity based on the equipment environmental parameters; compare the first ambient temperature with the first ambient temperature upper limit value in the preset environmental threshold to obtain a third comparison result; calculate a gradient descent rate for the second ambient temperature, and analyze the calculation result through the equipment parameters of the generator set equipment to obtain a temperature analysis result; dynamically match the ambient humidity with the humidity safety range of the generator set equipment to obtain a humidity matching result; determine a second comparison result of the generator set equipment based on the third comparison result, the temperature analysis result and the humidity matching result.

[0086] It should be noted that the first ambient temperature can be the average temperature of the entire ambient space where the generator set is located, or the ambient temperature of auxiliary equipment, such as the inlet air temperature of the lubricating oil cooler. The second ambient temperature can be the temperature of the core heat dissipation area of the generator set, or the local ambient temperature of key components of the generator set (such as the engine block and generator windings). Ambient humidity measures the humidity inside the control cabinet and can be measured using a capacitive humidity sensor.

[0087] Additionally, it's important to note that the upper limit of the first ambient temperature is a pre-set maximum allowable value based on equipment design and safe operation requirements. Exceeding this value may cause equipment failure. The safe humidity range is the allowable ambient humidity range within which the generator set equipment can operate safely and stably.

[0088] In one example, the generator set deploys dual redundant sensors at the air intake filter (second ambient temperature) and the turbocharger housing (first temperature point), with a sampling frequency of 10 Hz, and transmits the data to the PLC (Programmable Logic Controller) via the Modbus RTU protocol.

[0089] When obtaining the third comparison result, the upper limit of the first ambient temperature is dynamically adjusted according to the unit operation mode:

[0090] Cold start: The upper limit of the first ambient temperature is 85°C;

[0091] Hot operation: The upper limit of the first ambient temperature is 92°C.

[0092] If the limit is exceeded for five consecutive sampling periods (500ms), the third comparison result is triggered as abnormal. When the cylinder liner water temperature reaches 88°C (cold mode), the PLC triggers a third-level alarm and starts the auxiliary cooling pump (response time must be less than 2s).

[0093] When obtaining the temperature analysis results, the sliding window difference method is used to calculate the temperature drop rate of the second environment in the past 60 seconds. -6 / ℃), calculate the maximum allowable temperature drop rate.

[0094] When dynamically matching humidity, the safety interval model needs to be dynamically calculated based on the dew point temperature formula:

[0095]

[0096] Among them, T L is the dew point humidity, T M is the current humidity, and RH is the relative humidity.

[0097] When the difference between the cabinet temperature and the dew point is less than or equal to 3°C, a condensation warning is triggered. In high-temperature environments (greater than 40°C), the safety range is expanded (for example, RH≤75% to RH≤85%) to prevent false alarms from the sensor.

[0098] The third comparison result, temperature analysis result, and humidity matching result are combined. If all three results are "normal," the second comparison result is "normal." If any one result is "abnormal," the second comparison result is "abnormal." If any result is "needs attention," "too dry," or "too wet," the situation can be classified as "potential risk" or other specific conditions, and early warning indicators can be assigned to the generator set equipment.

[0099] Step S303: Perform risk assessment on the generator set equipment according to the first comparison result and the second comparison result to obtain an assessment result.

[0100] Furthermore, in order to ensure the safety of the equipment while minimizing unnecessary downtime and improving the flexibility and economy of equipment management, the step S303 may include:

[0101] When neither the first comparison result nor the second comparison result triggers the system protection condition, and the generator set equipment does not have a warning indicator, the evaluation result is determined to be a normal startup; when neither the first comparison result nor the second comparison result triggers the system protection condition, and the generator set equipment has a warning indicator, the evaluation result is determined to be an abnormal startup, and an equipment warning instruction is generated; when either the first comparison result or the second comparison result triggers the system protection condition, the evaluation result is determined to be an emergency shutdown, and an equipment isolation instruction is generated.

[0102] It should be noted that system protection conditions are pre-set safe operating conditions for equipment. When equipment operating parameters or environmental parameters approach but do not reach the threshold of the system protection conditions, it indicates a potential risk (such as the workload approaching the upper limit or the ambient temperature continuing to rise).

[0103] In one example, when the first comparison result (workload) is normal, the second comparison result (environmental parameters) is normal, and there are no early warning indicators, the equipment is in a safe operating state and continues to operate as planned; the first and second comparison results are normal, but there are early warning indicators (such as workload fluctuations, environmental parameters approaching thresholds). The equipment has potential risks, and the assessment result is determined to be an abnormal startup, requiring enhanced monitoring or pre-maintenance. Generate a device early warning instruction; the first comparison result (workload exceeds the limit) or the second comparison result (environmental parameter exceeds the limit) triggers the system protection condition, immediately stops the equipment operation, and isolates the source of the fault.

[0104] In another possible implementation, workload and environmental parameters can be assigned different weights based on device type, operating conditions, and historical data. For example, in high-temperature environments, the temperature parameter weight is increased to 50%, prioritizing thermal risk assessment; in high-load scenarios, the workload weight is increased to 60%, focusing on monitoring overload risks.

[0105] In this embodiment, when the startup time of the generator set equipment is less than the target operating time, the workload is compared with a preset load threshold to obtain a first comparison result; each parameter in the equipment environmental parameters is compared with the corresponding preset environmental threshold to obtain a second comparison result; and a risk assessment of the generator set equipment is performed based on the first and second comparison results to obtain an assessment result. A dual-level comparison mechanism of load thresholds and environmental parameter thresholds is employed to construct a dual-insurance logic for startup phase risk identification. By separating mechanical load risks from environmental coupling risks, accurate tracing of fault causes is achieved, avoiding misoperation of protection devices due to misjudgment of composite parameters in traditional methods.

[0106] Reference Figure 3 , Figure 3 This is a flow chart of the third embodiment of the device management method of the present application. Based on the above second embodiment, the third embodiment of the device management method of the present application is proposed.

[0107] In the third embodiment, step S40 includes:

[0108] Step S401: When the evaluation result is normal startup, maintain the current operating state of the generator set equipment.

[0109] Understandably, the assessment results indicate that the equipment is operating safely, the workload and environmental parameters are normal, and there are no warning indicators. The equipment can continue to operate as planned, and the "normal start" equipment can be maintained in operation to reduce unplanned downtime caused by misjudgment.

[0110] Specifically, the system triggers this operation when it confirms that the equipment is in a safe state through multi-dimensional parameter verification (load, environment, and operating time). The control module will maintain the set value of the PID controller unchanged, such as keeping the speed within the adjustment dead zone of ±5%, the fuel supply system maintains the current valve opening, and the cooling water circulation pump maintains the corresponding reference speed. At the same time, the bearing vibration data is continuously collected at a frequency of 10Hz, the winding insulation resistance test is performed every 30 seconds, and the power supply current of the humidity sensor is kept stable in the range of 4 to 20mA. If a sudden change is detected during the maintenance phase, the current control parameter snapshot is frozen and a fault log with a timestamp is generated. Ensure that the equipment can continue to operate stably after verification, while maintaining the ability to respond to abnormal conditions in real time.

[0111] Step S402: When the evaluation result is abnormal startup, the device early warning instruction is sent to the monitoring device, and subsequent evaluation results of the generator set equipment are continuously obtained.

[0112] It should be understood that the equipment warning instruction is a prompt message sent by the system to the monitoring device, which contains the type of equipment abnormality, such as high temperature, load fluctuation, etc.

[0113] It is understood that if the subsequent evaluation result indicates an abnormal startup, the system can send a device warning instruction to the monitoring device, indicating the type of abnormality (such as "ambient temperature is approaching the threshold"). The operation and maintenance personnel or the automated system will take pre-maintenance measures (such as adjusting the load and improving heat dissipation) based on the warning content, and continue to obtain subsequent evaluation results in real time to dynamically adjust the management strategy.

[0114] Step S403: When the evaluation result is an emergency shutdown, the equipment isolation instruction is sent to the power control device, and a fault alarm signal is generated for safety warning.

[0115] It should be understood that the equipment isolation instruction is an instruction sent by the system to the power control device to immediately cut off the power supply of the equipment and make it exit operation to prevent the spread of risks.

[0116] Specifically, if the assessment result indicates an emergency shutdown, the system sends an equipment isolation command to the power control device, immediately cutting off the power supply to the equipment. A fault alarm signal (such as an audible and visual alarm, or SMS notification) is generated to notify maintenance personnel, while also recording fault data (such as time, parameters, and cause) for subsequent analysis and repair.

[0117] In this embodiment, if the evaluation result is a normal startup, the current operating state of the generator set is maintained. If the evaluation result is an abnormal startup, the device warning instruction is sent to the monitoring device, and subsequent evaluation results of the generator set are continuously obtained. If the evaluation result is an emergency shutdown, the device isolation instruction is sent to the power control device, and a fault alarm signal is generated for safety warning. By dynamically adjusting the device operating mode (maintenance, warning, isolation), combined with the hierarchical delivery of fault alarm signals, it is possible to quickly respond to abnormal device states and shorten the fault handling cycle.

[0118] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the device management method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
