Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to a method and device for evaluating the status of a reactor. Background Art

[0002] In power systems, dry-type air-core reactors are mainly used for reactive power regulation and are widely used in power systems. In recent years, dry-type air-core reactors have frequently caught fire. In related technologies, dry-type air-core reactors use thinner conductors as windings, so that the dry-type air-core reactor has more turns at the same height to ensure the inductance value. The capacity is increased by connecting multiple branches in parallel; multiple branches are wrapped with glass fiber impregnated with epoxy resin to form an envelope. The envelopes all adopt a coaxial cylindrical structure, and the capacity is proportional to the number of envelopes; epoxy glass fiber drawing rods are used as supports between two adjacent envelopes to form an air channel for heat dissipation and insulation between the two envelopes; the beginning and end of all the wires in each set of envelopes are welded to the aluminum alloy busbar.

[0003] Dry-type air-core reactors have only longitudinal insulation, not main insulation. Voltages are essentially the same within the same enclosure at the same height, so insulation problems in dry-type air-core reactors often occur between turns. Furthermore, due to this structure, dry-type air-core reactors have numerous branches and turns. When an inter-turn short circuit occurs, the reactor's power-frequency impedance remains virtually unchanged, preventing the main circuit's voltage and current transformers from detecting the short in a timely manner. The shorted turn generates significant heat, which can accumulate over time and eventually lead to the reactor catching fire.

[0004] Currently, no effective solution has been proposed to the problem of inaccurate detection results of inter-turn insulation faults in dry-type air-core reactors in related technologies. Summary of the Invention

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] The present invention will be described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a method for evaluating the state of a reactor according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0027] Step S101 : collecting first data to be evaluated when the target reactor is in an operating state, and collecting second data to be evaluated when the target reactor is in a non-operating state.

[0028] Specifically, the target reactor can be a dry-type air-core reactor. The first data to be evaluated can include first appearance data, sound data, infrared thermal imaging data, and ultrasonic data. The second data to be evaluated can include second appearance data, withstand voltage test data, resistance test data, and reactance test data. The target reactor is evaluated for abnormalities by collecting the first data to be evaluated when the reactor is in operation and the second data to be evaluated when the reactor is not in operation.

[0029] Step S102 : determining a first evaluation value based on first data to be evaluated and standard operating data of a standard reactor, wherein the standard reactor is a reactor without abnormality, and the standard operating data is data obtained when the standard reactor is in operation.

[0030] Specifically, the first evaluation value is determined by comparing the collected first data to be evaluated with the standard operating data of the standard inductor. For example, the noise of the target inductor and the standard inductor is monitored by a sound level meter, and the first evaluation value is determined based on the monitored noise comparison result, thereby evaluating whether the target inductor has an abnormality.

[0031] Step S103 : determining a second evaluation value based on the second data to be evaluated and standard test data of the standard reactor, wherein the standard test data is data obtained by testing the standard reactor in a non-operating state.

[0032] Specifically, the second evaluation value is determined by comparing the collected second data to be evaluated with the standard test data of the standard reactor. For example, a DC resistance tester is used to measure the resistance value of the target reactor and the resistance value of the standard reactor for comparison. The second evaluation value is determined based on the comparison result, and then it is evaluated whether the target reactor has an abnormality.

[0033] Step S104 : Calculate a state evaluation value of the target reactor based on the first evaluation value and the second evaluation value.

[0034] Specifically, weights of the first evaluation value and the second evaluation value are set according to expert experience, and the state evaluation value of the target reactor is calculated by weighted summing the first evaluation value and the second evaluation value based on the weights.

[0035] Step S105 : When the state evaluation value is greater than or equal to the state evaluation value threshold, it is determined that the target reactor has no abnormality.

[0036] Specifically, the state evaluation value of the abnormal reactor is determined based on the historical fault records of the reactor, and then the state evaluation value threshold is determined based on the state evaluation value of the abnormal reactor. By comparing the state evaluation value of the target reactor and the state evaluation value threshold, if the state evaluation value is greater than or equal to the state evaluation value threshold, it means that the target reactor is not abnormal; if the state evaluation value is less than the state evaluation value threshold, it means that the target reactor may be abnormal.

[0037] The reactor status assessment method provided in an embodiment of the present application collects first data to be assessed when the target reactor is in an operating state, and collects second data to be assessed when the target reactor is in a non-operating state; determines a first assessment value based on the first data to be assessed and standard operating data of a standard reactor, wherein the standard reactor is a reactor without abnormalities, and the standard operating data is data obtained when the standard reactor is in an operating state; determines a second assessment value based on the second data to be assessed and standard test data of the standard reactor, wherein the standard test data is data obtained by testing the standard reactor in a non-operating state; calculates a status assessment value of the target reactor based on the first assessment value and the second assessment value; and determines that the target reactor has no abnormalities when the status assessment value is greater than or equal to a status assessment value threshold, thereby solving the problem of inaccurate detection results of inter-turn insulation faults of dry-type air-core reactors in related technologies. By collecting the first data to be evaluated when the target reactor is in the operating state and the second data to be evaluated when it is in the non-operating state, the state evaluation value of the target reactor is determined based on the first data to be evaluated and the second data to be evaluated, and then it is determined whether the target reactor is abnormal based on the state evaluation value, thereby achieving the effect of comprehensively evaluating the operating state of the reactor, timely discovering the inter-turn insulation fault of the dry-type air-core reactor, and improving the accuracy of abnormal state detection of the reactor.

[0038] Optionally, in the reactor status assessment method provided in an embodiment of the present application, collecting first data to be evaluated when the target reactor is in an operating state, and collecting second data to be evaluated when the target reactor is in a non-operating state include: obtaining one of the following data when the target reactor is in an operating state: first appearance data, sound data, infrared thermal imaging data, and ultrasonic data; determining the collected data when the target reactor is in an operating state as the first data to be evaluated; obtaining one of the following data when the target reactor is in a non-operating state: second appearance data, voltage withstand test data, resistance test data, and reactance test data; and determining the collected data when the target reactor is in a non-operating state as the second data to be evaluated.

[0039] Specifically, the status evaluation of the dry-type air-core reactor can include collecting the first data to be evaluated in the operating state, for example, the live detection items include appearance inspection evaluation (i.e., first appearance data), abnormal body noise and vibration evaluation (i.e., sound data), reactor infrared thermal imaging detection evaluation (i.e., infrared thermal imaging data), and ultrasonic detection evaluation (i.e., ultrasonic data). The above detection data can be arbitrarily combined as the first data to be evaluated. When collecting the first data to be evaluated in the operating state, it is necessary to wait until the AVC (Automatic Voltage Control, smart grid control) system controls the target reactor to be put into operation, and the operating time is in the early morning and at night, to carry out on-site live detection and evaluation of the dry-type reactor. The inspection contents of the appearance inspection and evaluation are to inspect whether there are any abnormalities in the overall appearance of the dry-type hollow reactor and whether there are any abnormalities visible to the naked eye, such as cracks in the outer shell and insufficient tightening of the wires; the inspection contents of the abnormal body noise and vibration evaluation are to check whether the oscillation noise and vibration are different from the normal excitation of the standard reactor, and whether there are any abnormal noise and vibration; the inspection contents of the infrared thermal imaging detection and evaluation of the reactor are to use an infrared thermal imager to measure the temperature of the outer shell and the upper and lower star frames of the reactor, and the infrared thermal image shows whether there is any abnormal temperature rise, temperature difference and / or relative temperature difference; the ultrasonic detection and evaluation is to use ultrasonic detection instruments to carry out dry-type reactor status monitoring to detect whether the target reactor has abnormal ultrasonic signals.

[0040] The status assessment of dry-type air-core reactors can also include collecting second data to be evaluated in a non-operating state. For example, the power outage detection items include the appearance status assessment of the inter-encapsulation support bars and air ducts (i.e., the second appearance data), the dry-type air-core reactor inter-turn insulation oscillation wave withstand voltage test assessment (i.e., withstand voltage test data), the reactor coil conductor DC resistance assessment (i.e., resistance test data), and the reactor reactance measurement assessment (i.e., reactance test data). The above test data can be arbitrarily combined as the second data to be evaluated. When collecting the second data to be evaluated in the non-operating state, technicians are required to apply for a power outage and arrange safety measures, disconnect the leads of the reactor terminals, and conduct on-site power outage testing. The inspection content of the inter-encapsulation support and air duct status assessment includes checking whether the encapsulation is detached or moved upward, and whether there are foreign objects in the air duct. The judgment standard is to check whether there are any abnormalities visible to the naked eye and whether there are foreign objects in the air duct. The inspection content of the dry-type air-core reactor inter-turn insulation oscillation wave withstand voltage test is to use a high-frequency exponentially decayed oscillation inter-turn insulation test device to conduct an inter-turn insulation withstand voltage test to determine whether the target reactor can withstand the cumulative effect of an exponentially decayed oscillation voltage lasting 3000 times for 1 minute. The inspection content of the reactor coil conductor DC resistance test is to use a winding DC resistance meter to measure the resistance value to determine whether it is similar to that of the standard reactor. The inspection content of the reactor reactance measurement test is to measure the total impedance of the reactor using a high-frequency exponentially decayed oscillation inter-turn insulation test device to determine whether the impedance value of the target reactor is similar to that of the standard reactor. This embodiment determines whether the target reactor is abnormal by determining the first value to be evaluated and the second value to be evaluated.

[0041] It should be noted that the power outage test specifically includes: arranging on-site safety measures. Checking the integrity of safety tools and equipment, and installing insulating mats, safety fences, and signage. Testing the air-core reactor for electrical power and discharging it to ground, using tools such as insulating rods; do not touch the discharge conductors with your hands. Disconnecting the busbars at both ends of the air-core reactor terminal block. Visually inspecting the air-core reactor and cleaning its surface. Removing paint and metal oxide from the contact surfaces of the air-core reactor terminal block.

[0042] Optionally, in the state assessment method of the reactor provided in an embodiment of the present application, determining the first evaluation value based on the first data to be evaluated and the standard operating data of the standard reactor includes: obtaining the operating data evaluation value of the first data to be evaluated, and calculating the sum of all operating data evaluation values ​​to obtain the first evaluation value, wherein the operating data evaluation value includes at least one of the following: a first image evaluation value, a sound data evaluation value, an infrared data evaluation value, and an ultrasonic data evaluation value; determining the second evaluation value based on the second data to be evaluated and the standard test data of the standard reactor includes: obtaining the test data evaluation value of the second data to be evaluated, and calculating the sum of all test data evaluation values ​​to obtain the second evaluation value, wherein the test data evaluation value includes at least one of the following: a second image evaluation value, a withstand voltage evaluation value, a resistance evaluation value, and a reactance evaluation value.

[0043] Specifically, the first data to be evaluated can be any combination of first image evaluation values, sound data evaluation values, infrared data evaluation values, and ultrasonic data evaluation values. Therefore, after determining which operational data evaluation values ​​are included in the first data to be evaluated, the sum of all operational data evaluation values ​​is calculated to obtain a first evaluation value. The second data to be evaluated can be any combination of second image evaluation values, withstand voltage evaluation values, resistance evaluation values, and reactance evaluation values. Therefore, after determining which test data evaluation values ​​are included in the second data to be evaluated, the sum of all test data evaluation values ​​is calculated to obtain a second evaluation value. The state evaluation value of the target reactor is determined by calculating the first and second evaluation values.

[0044] The operation data evaluation value is determined by comparing the first data to be evaluated of the target inductor and the operation data of the standard inductor. Optionally, in the state evaluation method of the inductor provided in the embodiment of the present application, obtaining the operation data evaluation value of the first data to be evaluated includes: obtaining a first image of the target inductor and a standard image of the standard inductor, and determining the first image evaluation value based on the comparison result between the first image and the standard image, wherein the first image at least includes: the surface coating area of ​​the target inductor, the encapsulation surface area, the air guide support bar area between the encapsulation, the fastening belt area between the encapsulation and the bracket, and the ventilation duct area; and / or measuring the target sound data of the target inductor and the standard sound data of the standard inductor by a sound level meter, and determining the sound data evaluation value based on the comparison result between the target sound data and the standard sound data; and / or measuring the target infrared data of the target inductor and the standard infrared data of the standard inductor by an infrared thermal imaging instrument, and determining the infrared data evaluation value based on the comparison result between the target infrared data and the standard infrared data; and / or measuring the target ultrasonic data of the target inductor and the standard ultrasonic data of the standard inductor by an ultrasonic detection instrument, and determining the ultrasonic data evaluation value based on the comparison result between the target ultrasonic data and the standard ultrasonic data.

[0045] Specifically, since the target reactor will not generate significant noise, infrared, or ultrasonic signals until it is put into operation, a condition assessment must be conducted when the target reactor is put into operation. By comparing the first image with the standard image, a visual inspection of the dry-type hollow reactor is performed to observe whether the surface coating of the target reactor is damaged, peeling, or cracked. Check for traces of creepage on the encapsulation surface. Check for looseness or detachment of the air guide braces between the reactor encapsulation. Check for looseness or breakage of the fastening straps between the encapsulation and the bracket of the target reactor. Check for blockage in the ventilation duct and whether the body of the target reactor is clean, free of dust, foreign matter, glue flow, or cracks. Check for obvious detachment or displacement of the support bars. The first image evaluation value is determined by the similarity between the first image and the standard image.

[0046] The target sound data can be the steady-state noise, unstable noise, and impulse noise of the target reactor during operation, measured using a sound level meter. An integrating sound level meter measures the effective sound level of unstable noise over a period of time, while a pulse sound level meter measures impulse noise. The standard sound data is the steady-state noise, unstable noise, and impulse noise of a standard reactor during operation, measured using a sound level meter. The sound data evaluation value is calculated by calculating the similarity between the target reactor and the standard reactor's noise.

[0047] The temperature of the outer envelope and the upper and lower star frames of the target inductor within a preset period is measured by an infrared thermal imager to determine the temperature rise, temperature difference and / or relative temperature difference in the infrared thermal image. The temperature of the outer envelope and the upper and lower star frames of the standard inductor within a preset period is also measured to further determine the temperature rise, temperature difference and / or relative temperature difference in the infrared thermal image of the standard inductor. The infrared data evaluation value is obtained by calculating the similarity of the temperature rise, temperature difference and / or relative temperature difference between the target inductor and the standard inductor.

[0048] An ultrasonic testing instrument is used to measure target ultrasonic data of a target reactor and standard ultrasonic data of a standard reactor, and an ultrasonic data evaluation value is determined by calculating the similarity between the target ultrasonic data and the standard ultrasonic data. In this embodiment, the first evaluation value is calculated by determining a first image evaluation value, an acoustic data evaluation value, an infrared data evaluation value, and an ultrasonic data evaluation value.

[0049] It should be noted that ultrasound can be used for flaw detection. Internal defects in reactor materials are detected by leveraging the acoustic properties of the reactor's materials and defects to determine the energy variation in the ultrasonic wave's reflection and penetration time. For the same homogeneous medium, the pulse wave's propagation time is proportional to the acoustic path. Therefore, the presence of a defect echo signal can be used to determine the presence of a reactor defect. The echo signal's location can be used to determine the defect's distance from the detection surface, effectively locating the defect. The echo amplitude can also be used to determine the defect's magnitude.

[0050] Optionally, in the state assessment method of the reactor provided in an embodiment of the present application, when the operating data evaluation value includes a first image evaluation value, a sound data evaluation value, an infrared data evaluation value and an ultrasonic data evaluation value, before calculating the sum of all the operating data evaluation values ​​to obtain the first evaluation value, the method further includes: when the first image evaluation value is less than the image evaluation value threshold, and / or the sound data evaluation value is less than the sound data evaluation value threshold, and / or the infrared data evaluation value is less than the infrared data evaluation value threshold, and / or the ultrasonic data evaluation value is less than the ultrasonic data evaluation value threshold, determining that an abnormality has occurred in the target reactor; when the first image evaluation value is greater than or equal to the image evaluation value threshold, the sound data evaluation value is greater than or equal to the sound data evaluation value threshold, the infrared data evaluation value is greater than or equal to the infrared data evaluation value threshold, and the ultrasonic data evaluation value is greater than or equal to the ultrasonic data evaluation value threshold, determining that no abnormality has occurred in the first data to be evaluated.

[0051] Specifically, after determining the first image evaluation value, the sound data evaluation value, the infrared data evaluation value, and the ultrasonic data evaluation value, since any one of the evaluation values ​​can detect whether the target reactor is currently abnormal, whether the target reactor is abnormal is determined by judging whether each evaluation value is less than a preset evaluation value threshold. If any one or more evaluation values ​​are less than the corresponding evaluation value threshold, it indicates that the target reactor is abnormal. If all evaluation values ​​are greater than or equal to the corresponding evaluation value threshold, it indicates that the first data to be evaluated is not abnormal. This embodiment determines whether the target reactor is abnormal by comparing each data evaluation value with the corresponding evaluation value threshold.

[0052] The test data evaluation value is determined by comparing the second data to be evaluated of the target inductor with the test data of the standard inductor. Optionally, in the state evaluation method of the inductor provided in the embodiment of the present application, obtaining the test data evaluation value of the second data to be evaluated includes: obtaining a second image of the target inductor and a standard image of the standard inductor, and determining the second image evaluation value based on the comparison result between the second image and the standard image, wherein the second image includes at least: the surface coating area of ​​the target inductor, the encapsulation surface area, the air guide support bar area between the encapsulation, the fastening belt area between the encapsulation and the bracket, and the ventilation duct area; and / or through an inter-turn insulation test The device applies a preset voltage to the target inductor and the standard inductor, obtains the target voltage waveform data of the target inductor and the standard waveform data of the standard inductor, and determines the withstand voltage evaluation value based on the comparison result of the target voltage waveform data and the standard waveform data; and / or measures the target resistance value of the target inductor and the standard resistance value of the standard inductor through a winding DC resistance measuring instrument, and determines the resistance evaluation value based on the comparison result of the target resistance value and the standard resistance value; and / or measures the target impedance value of the target inductor and the standard impedance value of the standard inductor through a turn-to-turn insulation test device, and determines the reactance evaluation value based on the comparison result of the target impedance value and the standard impedance value.

[0053] Specifically, the dry-type hollow reactor is visually inspected by comparing the second image with the standard image to observe whether the surface coating of the target reactor is damaged, peeled off, or cracked. Whether there are traces of creepage on the surface of the package. Whether the air guide support bars between the reactor package are loose or falling off. Whether the fastening belt between the package and the bracket of the target reactor is loose or broken. Whether there is blockage in the ventilation duct, whether the body of the target reactor is clean and free of dust, foreign matter, glue flow, and cracks. Whether the support bar is obviously falling off or shifting. The similarity between the second image and the standard image is determined as the second image evaluation value.

[0054] Using a high-frequency exponentially decayed oscillation interturn insulation tester, a preset voltage is applied to a target reactor and a standard reactor. The target voltage waveform data for the target reactor and the standard waveform data for the standard reactor are obtained. The similarity between the target voltage waveform data and the standard waveform data is then calculated to determine the withstand voltage assessment value. For example, waveform comparison is used to determine the quality of interturn insulation in a reactor winding. For a single reactor, two voltages are applied across the air-core reactor: a calibration voltage and a test voltage. The calibration voltage should not exceed 30% of the test voltage. The resulting voltage waveforms are compared, and the change in the zero crossing point and the decay rate are observed to determine the insulation integrity. Figure 2 is a schematic diagram of standard waveform data provided according to an embodiment of the present application, such as Figure 2As shown in the figure, when there is no insulation defect between the turns of the reactor, the frequency and attenuation of the standard voltage waveform and the voltage waveform during the full voltage test are basically the same, indicating that there is no significant difference in the conditions inside the reactor under the calibrated voltage and the rated test voltage, and the insulation between the turns of the reactor is intact. Figure 3 is a schematic diagram of target waveform data provided according to an embodiment of the present application, such as Figure 3 As shown, the waveform zero crossings clearly do not overlap. The frequency and attenuation of the voltage waveforms during the standard voltage test and full-voltage test differ significantly, indicating significant differences in the internal conditions of the reactor at the standard voltage and full-voltage test voltages, indicating that the reactor's interturn insulation has developed problems at the full test voltage. Furthermore, if the reactor has an interturn short-circuit fault, the test may be accompanied by noise, smoke, and spark discharges.

[0055] Use a DC resistance tester to measure the DC resistance of the target reactor. Calculate the difference between the target resistance and the standard resistance as the resistance evaluation value. It is important to note that the measured target resistance value should follow the same pattern of variation as the factory setting. The difference between the DC resistance values ​​of the three-phase reactor windings should not exceed 2% of the three-phase average. The DC resistance of the target reactor should not vary by more than 2% compared to the factory setting at the same temperature.

[0056] The target impedance value of the target reactor and the standard impedance value of the standard reactor are measured using a turn-to-turn insulation test device, and the difference between the target impedance value and the standard impedance value is calculated to obtain the reactance evaluation value. In this embodiment, the second evaluation value is calculated by determining the second image evaluation value, the withstand voltage evaluation value, the resistance evaluation value, and the reactance evaluation value.

[0057] Optionally, in the state assessment method of the reactor provided in an embodiment of the present application, when the test data evaluation value includes a second image evaluation value, a withstand voltage evaluation value, a resistance evaluation value and a reactance evaluation value, before calculating the sum of all test data evaluation values ​​to obtain the second evaluation value, the method further includes: when the second image evaluation value is less than the image evaluation value threshold, and / or the withstand voltage evaluation value is less than the withstand voltage evaluation value threshold, and / or the resistance evaluation value is less than the resistance evaluation value threshold, and / or the reactance evaluation value is less than the reactance evaluation value threshold, determining that the target reactor has an abnormality; when the second image evaluation value is greater than or equal to the image evaluation value threshold, the withstand voltage evaluation value is greater than or equal to the withstand voltage evaluation value threshold, the resistance evaluation value is greater than or equal to the resistance evaluation value threshold, and the reactance evaluation value is greater than or equal to the reactance evaluation value threshold, determining that the second data to be evaluated has no abnormality.

[0058] Specifically, after determining the second image evaluation value, the withstand voltage evaluation value, the resistance evaluation value, and the reactance evaluation value, since any one of the evaluation values ​​can detect whether the target reactor is currently abnormal, whether the target reactor is abnormal is determined by judging whether each evaluation value is less than a preset evaluation value threshold. If any one or more evaluation values ​​are less than the corresponding evaluation value threshold, it indicates that the target reactor is abnormal. If all evaluation values ​​are greater than or equal to the corresponding evaluation value threshold, it indicates that the second data to be evaluated is not abnormal. This embodiment determines whether the target reactor is abnormal by comparing the evaluation value of each data with the corresponding evaluation value threshold.

[0059] Optionally, in the reactor state assessment method provided in an embodiment of the present application, calculating the target reactor state assessment value based on the first assessment value and the second assessment value includes: determining a first weight of the first assessment value and a second weight of the second assessment value; performing weighted summation of the first assessment value and the second assessment value based on the first weight and the second weight to obtain the target reactor state assessment value.

[0060] Specifically, the first weight and the second weight can be manually set, and the first evaluation value and the second evaluation value are weighted and summed according to the first weight and the second weight to obtain the state evaluation value of the target reactor. The first weight and the second weight can be adjusted at any time based on manual experiments. In this embodiment, a comprehensive state evaluation of the target reactor is performed by calculating the state evaluation value.

[0061] Optionally, in the reactor status assessment method provided in an embodiment of the present application, after calculating the target reactor status assessment value based on the first assessment value and the second assessment value, the method further includes: when the status assessment value is less than a status assessment value threshold, judging whether the first data to be assessed and the second data to be assessed are abnormal; when the first data to be assessed and / or the second data to be assessed are abnormal, determining that the target reactor is abnormal; when neither the first data to be assessed nor the second data to be assessed are abnormal, issuing a prompt message, wherein the prompt message is used to prompt that there is an abnormal risk for the target reactor.

[0062] Specifically, although neither the first data to be evaluated nor the second data to be evaluated may be abnormal, the target reactor may still be at risk of an abnormality. Therefore, a state assessment value threshold is manually set. When the calculated state assessment value of the target reactor is less than the state assessment value threshold, a prompt message is issued to indicate that the target reactor is at risk of an abnormality and requires timely maintenance of the target reactor. This embodiment promptly identifies potential risks of the target reactor by comparing the state assessment value with the state assessment value threshold.
