Description

Technical Field

[0001] The present application relates to the technical field of voltage transformers, and in particular to a voltage transformer testing method, system, storage medium and electronic equipment. Background Art

[0002] As a key device in the power system, the performance and accuracy of the voltage transformer directly affect the safe and stable operation of the power grid. Therefore, it is very important to conduct comprehensive and accurate testing of the voltage transformer. The voltage transformer is a device that converts high voltage into low voltage in proportion. It is mainly used in measurement, protection and control systems. Its working principle is based on the law of electromagnetic induction. Through the magnetic coupling between the primary winding and the secondary winding, the high voltage is reduced to a measurable level while keeping the voltage phase relationship basically unchanged. The voltage transformer can not only isolate the high-voltage circuit and the low-voltage measuring equipment, but also convert the high voltage into a standard low voltage in proportion, which is convenient for the use of instruments and relay protection devices.

[0003] In the related art, the test method for voltage transformers is to construct simulated working conditions according to each test item, such as voltage ratio error test, phase angle error test, insulation performance test, etc. Since complex simulated working conditions need to be constructed each time a test item is performed, the test efficiency is low. Summary of the invention

[0004] The present application provides a voltage transformer testing method, system, storage medium and electronic equipment, which can improve the testing efficiency while ensuring the testing accuracy of the voltage transformer.

[0005] In a first aspect, the present application provides a voltage transformer testing method, the method comprising: Acquire a scenario for a voltage transformer to be deployed, and determine a plurality of test items corresponding to the scenario for the voltage transformer to be deployed; Determine, from the plurality of test items, a first test item combination that is tested using the same simulated operating condition, and a second test item that is tested using an independent simulated operating condition, wherein the first test item combination includes a plurality of first test items; Using the test environment parameters corresponding to each of the first test items, updating the standard simulation working condition corresponding to the first test item combination to the target simulation working condition; The first test item of the voltage transformer under the target simulated working condition and the second test item of the voltage transformer under the independent simulated working condition are tested to obtain a comprehensive test result.

[0006] By adopting the above technical solution, the corresponding test items are selected according to the scenario to be deployed of the voltage transformer, and multiple test items are divided into a first test item combination that can share the same simulated working condition for testing and a second test item that needs a separate simulated working condition, thereby avoiding the inefficiency of repeatedly building a complex simulation environment and greatly improving the test efficiency. ; and the target simulated working condition is obtained by updating the parameters of each first test item, so that the test result is more accurate. Finally, the first test item and the second test item are tested respectively under different simulated working conditions, so that the test efficiency of the voltage transformer can be improved on the basis of ensuring the test accuracy.

[0007] Optionally, the acquiring a scenario for the voltage transformer to be deployed and determining a plurality of test items corresponding to the scenario for the voltage transformer to be deployed includes: Acquire the scenario in which the voltage transformer is to be deployed and special environmental indicators of the scenario in which the voltage transformer is to be deployed; Determine a standard scene type corresponding to the to-be-launched scene, where the standard scene type corresponds to a plurality of standard test items; The standard test items of the scene type are adjusted according to the special environment indicators to obtain multiple test items corresponding to the scene to be launched.

[0008] By adopting the above technical solution, on the basis of obtaining the scene to be deployed, the special environmental factors of the scene are also considered. These special environmental indicators can more comprehensively reflect the actual use conditions of the voltage transformer. On this basis, the standard test items are adjusted differently so that the final test items are more in line with the characteristics of the specific scene and the actual test requirements for the voltage transformer. In this way, it is helpful to plan the test plan in a targeted manner and improve the accuracy of the test.

[0009] Optionally, using the test environment parameters corresponding to each of the first test items to update the standard simulation working condition corresponding to the first test item combination to the target simulation working condition includes: Constructing a digital twin model corresponding to the standard voltage transformer according to the standard simulation working conditions corresponding to the first test item combination and the standard characteristic parameters of the standard voltage transformer; Inputting the test environment parameters of each of the first test items into the digital twin model respectively, and obtaining the output result impact value between each of the first test items; The standard simulation condition is updated to a target simulation condition according to the output result impact value.

[0010] By adopting the above technical solution, the performance of the standard voltage transformer is virtually simulated with the help of digital twin technology, and the interactive impact of different test environment parameters is analyzed, so as to optimize and generate the target simulation working condition, so that it can accurately simulate the working state of the voltage transformer in a complex actual environment. Compared with a single standard simulation working condition, the test results of the target simulation working condition are more accurate and reliable.

[0011] Optionally, the digital twin model includes a mathematical model and a dynamic simulation model, and constructing the digital twin model corresponding to the standard voltage transformer according to the standard simulation working condition corresponding to the first test item combination and the standard characteristic parameters of the standard voltage transformer includes: Acquire the standard characteristic parameters of the standard voltage transformer, and determine the mathematical model of the correlation between the output result of the standard voltage transformer in the working state and the actual value of the measured object; The dynamic simulation model of the standard voltage transformer is constructed according to the standard simulation working conditions corresponding to the first test item combination and the mathematical model.

[0012] By adopting the above technical solution, on the basis of the mathematical model, combined with the standard simulation conditions corresponding to the first test item combination, a dynamic simulation model of the standard voltage transformer is constructed. The dynamic simulation model can simulate and calculate the dynamic response behavior of the standard voltage transformer under various changing test environment conditions in real time. Compared with a single theoretical analysis or experimental test, this technical solution uses digital twin technology to restore the real working state of the standard voltage transformer to the maximum extent, fully consider the coupling effect of various environmental conditions, and avoid analysis deviations caused by simplified assumptions or test condition restrictions.

[0013] Optionally, the inputting the test environment parameters of each of the first test items into the digital twin model respectively to obtain the output result impact value between each of the first test items includes: Inputting the test environment parameters of each of the first test items into the digital twin model respectively, and obtaining the dynamic error of each of the first test items after simulating the dynamic response under the influence of other first test items, wherein the test environment parameters include frequency, magnetic field strength, temperature and humidity, phase, and noise signal; According to the dynamic error and the standard characteristic parameter of the standard voltage transformer, the output result influence value between the first test items is obtained.

[0014] By adopting the above technical solution, the digital twin model is first used to simulate the dynamic operating state of the standard voltage transformer under various single and composite test environment conditions, and the real-time deviation from the ideal output value, i.e., the dynamic error, is recorded. These dynamic error data fully reflect the comprehensive influence of different test environment parameters on the performance of the voltage transformer. Then, the dynamic error data is analyzed and processed with the known standard characteristic parameters of the standard voltage transformer (such as rated transformation ratio, phase error, frequency response characteristics, etc.), and the final output result deviation caused by the mutual influence between each first test item, i.e., the output result influence value, is calculated. It is possible to quantify and analyze the influence of the interaction of each test environment condition on the performance of the voltage transformer with high precision, and lay a solid data foundation for the subsequent optimization and generation of target simulation conditions. The target simulation condition comprehensively considers the coupling effect of multiple environmental conditions, and can more truly reflect the working state of the voltage transformer under actual complex conditions, ensuring the accuracy and reliability of the final test results.

[0015] Optionally, before obtaining a comprehensive test result of the first test item of the voltage transformer under the target simulated working condition and the second test item of the voltage transformer under the independent simulated working condition, the step further includes: Respectively obtaining a first time duration for the voltage transformer to recover to a normal state after the target simulated working condition, and a second time duration for the voltage transformer to recover to a normal state after the independent simulated working condition; The first time length is compared with the second time length to determine a testing sequence of the first test item and the second test item.

[0016] By adopting the above technical solution, the time efficiency of the entire test process is optimized by comparing and analyzing the impact of different test conditions on the voltage transformer. Reasonable test sequence arrangement can avoid unnecessary waiting, maximize the use of limited test time resources, and significantly improve test efficiency.

[0017] Optionally, after obtaining a comprehensive test result of the first test item of the voltage transformer under the target simulated working condition and the second test item of the voltage transformer under the independent simulated working condition, the step further includes: Determine whether there is any test item in the comprehensive test result whose test result does not meet the test standard; If there are test items in the comprehensive test results whose test results do not meet the test standards, the test items whose test results do not meet the test standards are determined as target test results, and the improvement parameters of the voltage transformer are determined according to the target test results.

[0018] By adopting the above technical solutions and through analysis and feedback of unqualified results, we can provide targeted guidance for product design improvements, achieve a virtuous cycle of testing, evaluation and optimization, and continuously improve product quality.

[0019] In a second aspect, the present application provides a voltage transformer testing system, the system comprising: A test item determination module, used to obtain a scenario to be deployed for a voltage transformer and determine a plurality of test items corresponding to the scenario to be deployed; A simulation working condition division module, used to determine a first test item combination that is tested using the same simulation working condition and a second test item that is tested using an independent simulation working condition from the plurality of test items, wherein the first test item combination includes a plurality of first test items; a simulation working condition updating module, configured to update the standard simulation working condition corresponding to the first test item combination to a target simulation working condition by using the test environment parameters corresponding to each of the first test items; The test module is used to test the first test item of the voltage transformer under the target simulated working condition and the second test item of the voltage transformer under the independent simulated working condition to obtain a comprehensive test result.

[0020] In a third aspect, the present application provides a computer storage medium, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing any one of the above methods.

[0021] In a fourth aspect, the present application provides an electronic device, comprising a processor, a memory and a transceiver, wherein the memory is used to store instructions, the transceiver is used to communicate with other devices, and the processor is used to execute the instructions stored in the memory so that the electronic device performs any one of the methods described above.

[0022] In summary, the beneficial effects brought about by the technical solution of this application include: By adopting the above technical solution, the corresponding test items are selected according to the scenario to be deployed of the voltage transformer, and multiple test items are divided into a first test item combination that can share the same simulated working condition for testing and a second test item that needs a separate simulated working condition, thereby avoiding the inefficiency of repeatedly building a complex simulation environment and greatly improving the test efficiency. ; and the target simulated working condition is obtained by updating the parameters of each first test item, so that the test result is more accurate. Finally, the first test item and the second test item are tested respectively under different simulated working conditions, so that the test efficiency of the voltage transformer can be improved on the basis of ensuring the test accuracy.

[0029] S101: Acquire a scenario for a voltage transformer to be deployed, and determine a plurality of test items corresponding to the scenario for the voltage transformer to be deployed.

[0030] Among them, the scenario to be launched refers to a specific type of power system environment in which the voltage transformer will be used. In the embodiments of the present application, it can be understood as a power system application scenario with specific characteristics and requirements, such as a microgrid scenario, a power grid operation scenario, and a new energy access scenario. The scenarios to be launched include but are not limited to microgrid scenarios, power grid operation scenarios, new energy access scenarios, smart grid scenarios, distribution network automation scenarios, and power system protection scenarios. In the embodiments of the present application, the significance of the scenarios to be launched is to clarify the application environment, determine the test focus, and guide the working condition simulation. By clearly defining specific types of scenarios to be launched, it is possible to formulate targeted test plans based on the characteristics and requirements of different scenarios.

[0031] Among them, the test items refer to the specific test contents for evaluating the performance and characteristics of the voltage transformer. In the embodiment of the present application, it can be understood as a series of special tests for different performance aspects of the voltage transformer, such as accuracy test, linearity test, stability test, dynamic response test, etc. It is used to evaluate the various performance indicators of the voltage transformer in a specific scenario to be deployed to ensure that it meets the actual application requirements of the scenario.

[0032] During specific implementation, the system obtains the scenario information of the voltage transformer to be deployed through a preset scenario database or a user input interface. The scenario database stores a variety of typical application scenarios, such as microgrid scenarios, power grid operation scenarios, new energy access scenarios, etc., as well as the key characteristic parameters of each scenario. Based on the acquired scenario information, the system automatically matches the set of test items that best suits the scenario to be deployed. For example, for the power grid operation scenario, the system may select accuracy test, stability test, and dynamic response test; for the new energy access scenario, the system may add linearity test, and may reduce some test items that are less relevant to the scenario.

[0033] Based on the above embodiment, as an optional implementation, step S101 specifically also includes S201-S203.

[0034] S201: Acquire the scenario in which the voltage transformer is to be deployed and the special environmental indicators of the scenario in which the voltage transformer is to be deployed.

[0035] Among them, special environmental indicators refer to non-standard environmental factors or conditions that affect the performance and test results of the voltage transformer. In the embodiment of the present application, it can be understood as specific environmental parameters or working conditions related to the scene to be deployed that may have a significant impact on the performance of the voltage transformer. It is used to more accurately simulate the complex environment that the voltage transformer may encounter in actual applications, so as to determine more targeted test items and improve the accuracy and practicality of the test. Special environmental indicators include but are not limited to temperature range, humidity level, altitude, electromagnetic interference intensity, vibration and shock level, pollution level, power grid characteristics and load characteristics.

[0036] During specific implementation, the system can obtain the scene information to be launched in a variety of ways. First, you can access the preset scenario database, which stores various typical application scenarios, such as microgrid scenarios, grid operation scenarios, new energy access scenarios, etc. Secondly, the system can receive specific scenario information through the user input interface. While obtaining basic scene information, the system also collects special environmental indicators related to it. In order to obtain more accurate special environmental indicators, the system may combine multiple data sources. For example, for meteorological data such as temperature and humidity, you can connect to the meteorological database or use historical statistical data; for grid characteristics, you can obtain them through power system monitoring data.

[0037] S202: Determine a standard scene type corresponding to the scene to be launched, where the standard scene type corresponds to a plurality of standard test items.

[0038] Among them, the standard scenario type refers to the classification of common and typical application environments and working conditions of voltage transformers. In the embodiments of the present application, it can be understood as a series of predefined and representative power system operation scenarios, which cover most common situations that voltage transformers may encounter in actual applications. It is used to provide a standardized reference framework for the testing of voltage transformers, helping to quickly determine the basic test items and parameter ranges.

[0039] Specifically, standard scenario types may include power grid operation scenarios, microgrid scenarios, new energy access scenarios, industrial power scenarios, distribution network scenarios, etc. Each standard scenario type has its own specific electrical characteristics, load characteristics, and environmental conditions. For example, the power grid operation scenario may focus on voltage stability and harmonic content, while the new energy access scenario may focus more on voltage fluctuations and frequency changes.

[0040] Among them, standard test items refer to a series of basic test contents and methods for voltage transformer performance and reliability evaluation. In the embodiment of the present application, it can be understood as a set of predefined test sets covering the main performance parameters of the voltage transformer, and these test items are formulated based on national standards, industry specifications and actual application requirements. It is used to comprehensively evaluate the basic performance indicators of the voltage transformer to ensure that it meets the basic application requirements and provide basic data support for subsequent specific scenario tests. Standard test items generally include but are not limited to accuracy tests, insulation performance tests, temperature rise tests, partial discharge tests, ferromagnetic resonance tests, frequency response tests, etc. These test items cover the core performance indicators of the voltage transformer, such as measurement accuracy, insulation strength, thermal stability, electromagnetic compatibility, etc. Each standard test item has its specific test method, test conditions and evaluation criteria, which are all formulated based on relevant standards and specifications.

[0041] In specific implementation, the system first analyzes the acquired scene information to be launched, including the basic characteristics of the scene and special environmental indicators. Then, the system matches this information with predefined standard scene types. Standard scene types may include grid operation scenes, microgrid scenes, new energy access scenes, industrial power consumption scenes, distribution network scenes, etc. The matching process uses intelligent algorithms to consider multiple factors, such as voltage level, load characteristics, grid topology, environmental conditions, etc. For example, if the information of the scene to be launched shows that it is located in an area with a large number of wind power generation and photovoltaic power generation equipment, the system may match it to the new energy access scene type. After determining the standard scene type, the system will automatically associate the standard test item set corresponding to the type. Each standard scene type has its specific test focus and requirements, so the corresponding standard test items will also be different. For example, for the new energy access scene, the standard test items may focus more on voltage fluctuation adaptability test, frequency response test and harmonic test; while for the industrial power consumption scene, it may focus more on temperature rise test and partial discharge test.

[0042] S203: Adjust the standard test items of the scene type according to the special environment indicators to obtain multiple test items corresponding to the scene to be launched.

[0043] During specific implementation, the system first analyzes the special environmental indicators obtained previously, which may include temperature range, humidity level, altitude, electromagnetic interference intensity, vibration and shock level, grid characteristics, and load characteristics. The system then compares and analyzes these special environmental indicators with the standard test items corresponding to the standard scenario types. Through this comparison, the system can identify which standard test items need to be adjusted and which additional test items need to be added. For example, if the special environmental indicators show that the scene to be deployed is located in a high altitude area, the system may adjust the parameters of the insulation performance test and add an insulation strength test under low air pressure. If the special environmental indicators indicate that there is high electromagnetic interference in the area, the system may add more stringent electromagnetic compatibility tests. For scenarios where the temperature range exceeds the normal range, the system may adjust the test conditions of the temperature rise test to ensure that the voltage transformer can work normally under extreme temperatures.

[0044] S102: Determine, from a plurality of test items, a first test item combination that is tested using the same simulation condition and a second test item that is tested using an independent simulation condition, wherein the first test item combination includes a plurality of first test items.

[0045] Among them, simulated working conditions refer to various conditions and states artificially created in a laboratory or test environment to imitate the actual operating environment of the voltage transformer. In the embodiment of the present application, it can be understood as a test environment and operating conditions that can simulate the characteristics of the scene to be put into use. These conditions cover electrical parameters, environmental factors, and possible abnormal conditions. Simulated working conditions are the process of converting the characteristics of the scene to be put into use into controllable and repeatable test conditions. It includes electrical parameter simulation, environmental condition simulation, load characteristic simulation, fault and abnormal condition simulation, and long-term operation simulation. For example, electrical parameter simulation includes simulation of voltage level, current size, power factor, frequency change, etc.; environmental condition simulation involves simulation of environmental factors such as temperature, humidity, air pressure, vibration, and electromagnetic interference; load characteristic simulation simulates different types of loads, such as linear loads, nonlinear loads, dynamic loads, etc.

[0046] Among them, the first test item combination refers to a set of test items that can share the same simulated working condition. In the embodiment of the present application, it can be understood as a set of core test items that can be performed continuously or in parallel in the same or highly similar simulation environment after screening and optimization for specific standard scenario types and special environmental indicators. It is used to efficiently and systematically evaluate the basic performance and key characteristics of voltage transformers in specific application scenarios.

[0047] Among them, the second test item refers to a special test item that needs to be tested under simulated working conditions separately. In the embodiment of the present application, it can be understood that due to its uniqueness, complexity or special environmental requirements, it is impossible to share the same simulated working conditions with other test items, and a test item must be performed separately in a specially set test environment. It is used to evaluate the performance of the voltage transformer under specific extreme conditions or special working conditions, and verify its reliability and stability in unconventional environments.

[0048] In the present embodiment, in the test process of the voltage transformer, in order to improve the test efficiency and ensure the accuracy of the test, the embodiment of the present application comprehensively considers the purpose of each test item, the required environmental conditions, the test equipment requirements and the interrelationship of the test results. Through this analysis, it is possible to identify which test items can be performed under the same or highly similar simulated working conditions, thereby forming a first test item combination. For example, voltage ratio error test, phase error test and temperature rise test may be classified as the first test item because they can be performed under similar temperature, humidity and voltage conditions. At the same time, the system will also identify those items that require special environments or equipment and cannot share simulated working conditions with other tests, and classify them as second test items, such as electromagnetic compatibility test or partial discharge test.

[0049] During the specific implementation, the system will preliminarily screen all test items according to the pre-set standard scenario types and special environmental indicators. Then, by analyzing the specific requirements and characteristics of each test item, determine which items can share the simulation conditions. These test items that can share the simulation conditions are combined into the first test item combination. For those items that cannot share the simulation conditions with other tests, they are determined as the second test items.

[0050] S103: Using the test environment parameters corresponding to each first test item, the standard simulation working condition corresponding to the first test item combination is updated to the target simulation working condition.

[0051] The test environment parameters refer to various physical and electrical conditions that need to be controlled and monitored during the voltage transformer test process. In the embodiment of the present application, it can be understood as a set of key variables for simulating the actual working environment of the voltage transformer, which can accurately describe and control the environmental conditions during the test process.

[0052] Among them, the standard simulation working condition is a set of test environment parameter combinations used to simulate various working conditions that the voltage transformer may encounter in typical application scenarios. The construction of these working conditions is based on in-depth analysis and comprehensive consideration of the operating characteristics of the power system, the application environment of the voltage transformer, and relevant standards and specifications. The design process of the standard simulation working condition involves the determination of multiple key environmental factors and the setting of parameter value ranges, such as temperature, humidity, electromagnetic interference intensity, power supply voltage fluctuations, and harmonic content. In an embodiment of the present application, the standard simulation working condition is mainly used for testing the first test item combination.

[0053] The target simulation working condition refers to the comprehensive test environment conditions set for multiple related test items during the voltage transformer test process. In the embodiment of the present application, it can be understood that by considering the mutual influence between multiple test items, the standard simulation working condition is optimized and adjusted to obtain a simulation condition closer to the actual use environment. It is used to simultaneously evaluate the performance of the voltage transformer on multiple related test items in a single test environment.

[0054] In this embodiment, the standard simulation condition is usually designed for a single test item, which cannot fully reflect the complex situation faced by the voltage transformer in the actual use environment. In actual applications, the voltage transformer is often affected by multiple environmental factors at the same time, and there may be interactions between these factors. Therefore, by updating to the target simulation condition, we can create a test condition that is closer to the actual use environment.

[0055] In the specific implementation, it is first necessary to obtain the test environment parameters corresponding to each first test item. These parameters may include but are not limited to temperature, humidity, electromagnetic interference intensity, vibration amplitude, etc., which reflect the specific environmental conditions simulated by each test item. Then, the relationship and possible interaction between these parameters are analyzed, and their comprehensive impact on the performance of the voltage transformer is considered. Based on these analysis results, the standard simulation conditions are adjusted and optimized to form a target simulation condition that can simultaneously reflect the influence of multiple environmental factors.

[0056] Based on the above embodiment, as an optional implementation, the step of updating the target simulation working condition in step S103 specifically includes S301-S303.

[0057] S301: Construct a digital twin model corresponding to the standard voltage transformer according to the standard simulation working conditions corresponding to the first test item combination and the standard characteristic parameters of the standard voltage transformer.

[0058] Among them, the standard voltage transformer refers to a high-precision voltage transformer that has been strictly calibrated and certified, and its performance parameters and measurement errors meet the requirements of relevant national or international standards. In the embodiment of the present application, it can be understood as an idealized voltage transformer model with known and stable characteristic parameters, including but not limited to rated transformation ratio, phase error, frequency response characteristics, etc. It is used as a benchmark for testing and calibrating other voltage transformers.

[0059] Among them, standard characteristic parameters refer to a series of key indicators and values ​​that describe the performance and behavior of standard voltage transformers. In the embodiments of the present application, it can be understood as various performance indicators of standard voltage transformers under ideal conditions. These indicators are obtained through rigorous testing and calibration and have high accuracy and reliability. Standard characteristic parameters usually include but are not limited to rated transformation ratio, phase error, frequency response characteristics, linearity, temperature coefficient, load characteristics, etc.

[0060] Among them, the digital twin model corresponding to the standard voltage transformer refers to a virtual simulation model built based on the characteristic parameters and behavioral characteristics of the standard voltage transformer. It is used to simulate and predict the performance of the standard voltage transformer under various test conditions in a virtual environment, providing a theoretical basis and data support for optimizing the target simulation conditions. This digital twin model can receive various test environment parameters as input, and obtain the expected output and error of the standard voltage transformer under these conditions through simulation calculation, thereby helping to analyze the mutual influence between different test items.

[0061] In this embodiment, in order to create a virtual, highly accurate standard voltage transformer model, it is used to simulate and predict performance under various test conditions. In the specific implementation, the comprehensive standard characteristic parameters of the standard voltage transformer are first collected, including the rated transformation ratio, phase error, frequency response characteristics, linearity, temperature coefficient and load characteristics. At the same time, the standard simulation conditions corresponding to the first test item combination are obtained, and these conditions reflect the standard test environment of each test item. Next, a mathematical model is constructed based on these data, which describes the correlation between the output results of the standard voltage transformer in the working state and the actual value of the object under test. Then, combined with the standard simulation conditions, a dynamic simulation model is developed, which can simulate the dynamic response of the standard voltage transformer under different environmental conditions. Finally, the mathematical model and the dynamic simulation model are integrated to form a complete digital twin model.

[0062] Based on the above embodiment, as an optional implementation, the digital twin model specifically includes a mathematical model and a dynamic simulation model, and step S301 specifically also includes S3011-S3012.

[0063] S3011: Obtain standard characteristic parameters of a standard voltage transformer, and determine a mathematical model of the correlation between an output result of the standard voltage transformer in a working state and an actual value of the object under test.

[0064] In the specific implementation, first obtain the standard characteristic parameters of the standard voltage transformer from the calibration certificate or technical specification, including the rated ratio, phase error, frequency response characteristics, linearity, temperature coefficient and load characteristics. These parameters are usually obtained by national metrology institutions through strict calibration procedures and have high accuracy and reliability. Then, based on these parameters, a mathematical model of the standard voltage transformer is established. The model usually includes an ideal ratio equation, an error compensation term and an environmental factor influence term. The ideal ratio equation describes the ideal relationship between the input voltage and the output voltage, the error compensation term takes into account the deviation between the actual ratio and the ideal ratio, and the environmental factor influence term reflects the influence of external conditions such as temperature and frequency on the measurement results. By combining these factors, a complete mathematical model can be obtained, which can accurately describe the correlation between the output result of the standard voltage transformer and the actual value of the measured object.

[0065] S3012: Construct a dynamic simulation model of a standard voltage transformer according to the standard simulation working conditions and mathematical model corresponding to the first test item combination.

[0066] A dynamic simulation model refers to a computer model that can simulate and predict the dynamic behavior of a system at different time points and environmental conditions. In the embodiments of the present application, it can be understood as a virtual simulation system based on the mathematical model of a standard voltage transformer and a standard simulation condition, which can simulate the dynamic response and performance of a standard voltage transformer in real time under various changing test environments. It is used to simulate the transient and steady-state behavior of a standard voltage transformer under different test conditions, predict its performance changes in a complex environment, analyze the impact of various test parameters on the output of the voltage transformer, and evaluate the interaction between different test items.

[0067] In this embodiment, in order to create a virtual simulation system that can simulate the dynamic response of a standard voltage transformer in various complex environments in real time, a reliable theoretical basis is provided for subsequent test optimization. In the specific implementation, the standard simulation conditions corresponding to the first test item combination are first collected, and these conditions include standard environmental parameters of each test item, such as frequency, magnetic field strength, temperature and humidity, phase, and noise signal. Then, these standard simulation conditions are combined with the mathematical model established in the previous step, and a dynamic simulation model is constructed using computer simulation software (such as MATLAB Simulink or LabVIEW). During the construction process, it is necessary to convert the various parameters and relationships in the mathematical model into modules and connections in the simulation software, and set appropriate solvers and simulation steps to ensure the calculation accuracy and efficiency of the model. Next, the various parameters in the standard simulation conditions are set as input variables of the model, so that the model can calculate the output response of the standard voltage transformer in real time according to these inputs. Finally, through multiple iterations and verifications, the dynamic simulation model is debugged and optimized to ensure that it can accurately reflect the dynamic behavior of the standard voltage transformer under various conditions.

[0068] S302: Input the test environment parameters of each first test item into the digital twin model respectively to obtain the output result impact value between each first test item.

[0069] Among them, the output result impact value refers to the quantitative impact of one test item on the measurement result of another test item when multiple test items are carried out simultaneously. In the embodiment of the present application, it can be understood as the deviation of the output result of the voltage transformer caused by the interaction between the first test items, and this deviation reflects the degree of influence of the interaction effect between different test environment factors on the measurement result. It is used to quantitatively evaluate the mutual influence between different test items.

[0070] In this embodiment, in order to quantitatively evaluate the mutual influence between different test items, data support is provided for creating a target simulation working condition that is closer to the actual use environment. In the specific implementation, the test environment parameters of each first test item are first collected, which may include temperature, humidity, frequency, magnetic field strength, phase, etc. Then, these parameters are input one by one into the digital twin model constructed in the previous step. The digital twin model simulates the performance of the standard voltage transformer under various test conditions according to the input parameters. By comparing the simulation results of a single test item and multiple test items at the same time, the output result impact value between each first test item can be calculated. This process requires running the model multiple times to simulate the situation where each test item is performed alone, and the situation where multiple test items are performed in combination. By comparing these simulation results, the degree of influence of each test item on the measurement results of other items can be obtained.

[0071] Based on the above embodiment, as an optional implementation, step S302 specifically also includes S3021-S3022.

[0072] S3021: Input the test environment parameters of each first test item into the digital twin model respectively to obtain the dynamic error of each first test item after simulating the dynamic response under the influence of other first test items. The test environment parameters include frequency, magnetic field strength, temperature and humidity, phase and noise signal.

[0073] In the specific implementation, the test environment parameters of each first test item are first collected, including frequency, magnetic field strength, temperature and humidity, phase, and noise signal. These parameters fully reflect the various conditions that the voltage transformer may face in the actual use environment. Then, these parameters are input into the digital twin model constructed in the previous steps in different combinations. The digital twin model simulates the dynamic response of the standard voltage transformer under various complex test conditions based on the input parameter combination. By comparing the difference between the simulated output results and the ideal output results, the dynamic error of each test item under the influence of other test items can be calculated. This process requires running the model multiple times to simulate various possible test environment combinations to obtain comprehensive dynamic error data. During the simulation process, special attention is paid to the interaction between different environmental parameters, such as the effect of temperature on frequency response, or the effect of magnetic field strength on phase error.

[0074] S3022: Obtain output result influence values ​​between the first test items according to the dynamic error and the standard characteristic parameters of the standard voltage transformer.

[0075] Among them, dynamic error refers to the real-time deviation of the output result of the standard voltage transformer relative to the ideal output value when multiple test items are carried out simultaneously. This deviation reflects the performance of the voltage transformer in a complex and dynamically changing test environment. It is used to evaluate the measurement accuracy of the voltage transformer under actual working conditions, analyze the mutual influence between different test items, and optimize the test plan and improve the voltage transformer design. The calculation of dynamic error takes into account the comprehensive influence of the environmental parameters of each test item on the performance of the standard voltage transformer. It can reflect the response characteristics of the voltage transformer when facing rapidly changing test conditions.

[0076] During the specific implementation, the dynamic error data of each first test item under the influence of other first test items obtained in the previous step are first used. These dynamic error data reflect the performance deviation of the voltage transformer in a complex test environment. Then, data analysis and processing are performed in combination with the standard characteristic parameters of the standard voltage transformer, such as rated transformation ratio, phase error, frequency response characteristics, etc. This process needs to consider the relationship between dynamic error and standard characteristic parameters, as well as the interaction effect between different test items. By comparing the ideal output of a single test item with the actual output under the influence of other test items, the degree of influence of each test item on other items can be calculated. This calculation needs to take into account the benchmark value provided by the standard characteristic parameters to ensure that the obtained impact value accurately reflects the deviation from the standard performance.

[0077] S303: Update the standard simulation condition to the target simulation condition according to the output result impact value.

[0078] In the specific implementation, first analyze the output result influence values ​​between the first test items obtained in the previous step. These influence values ​​quantitatively reflect the degree of interaction between different test items. Then, adjust the standard simulation conditions according to these influence values. During the adjustment process, it is necessary to focus on those test item combinations that have significant mutual influence and optimize their test parameters. For example, if it is found that there is a large mutual influence between frequency and temperature, it is necessary to consider the changes of these two factors in the target simulation conditions. When adjusting, it is also necessary to consider the actual adjustable range and equipment limitations of each test parameter to ensure that the updated conditions are feasible. In addition, it may be necessary to introduce new test parameters or adjust the test order to better simulate the complex situations in the actual use environment. Through these adjustments, the standard simulation conditions are optimized to become target simulation conditions that are closer to reality.

[0079] S104: testing a first test item of the voltage transformer under a target simulated working condition and a second test item of the voltage transformer under an independent simulated working condition to obtain a comprehensive test result.

[0080] In this embodiment, in order to comprehensively evaluate the performance of the voltage transformer in a complex actual environment and under specific single conditions, comprehensive and accurate test data can be obtained. In the specific implementation, the test environment is first set according to the optimized target simulation working condition, and the voltage transformer is tested for the first test item. These test items may include frequency response, phase error, temperature influence and other aspects, which are carried out simultaneously under the target simulation working condition to simulate the working state of the voltage transformer in the actual complex environment. During the test, it is necessary to accurately control various parameters to ensure that the test conditions are consistent with the target simulation working condition. At the same time, it is also necessary to test the second test item, which is carried out under independent simulation working conditions, and each test item is carried out separately and is not affected by other factors. The second test item may include insulation performance, mechanical strength and other items that need to be evaluated separately under specific conditions. In this way, the comprehensive performance of the voltage transformer in a complex environment is evaluated, and its independent performance data under specific conditions is obtained. High-precision measuring equipment needs to be used during the test, and the operation is carried out according to the standardized test process to ensure the accuracy and reliability of the data. After the test is completed, all test data are summarized and analyzed to obtain a comprehensive test result.

[0081] In an optional implementation, steps S401 - S402 are further included before step S104 .

[0082] S401: respectively obtaining a first time duration for a voltage transformer to recover to a normal state after a target simulated working condition, and a second time duration for a voltage transformer to recover to a normal state after an independent simulated working condition.

[0083] Among them, the first duration refers to the time required for the voltage transformer to return to the initial normal state after the target simulated working condition test. In the embodiment of the present application, it can be understood as the recovery time required for the voltage transformer to return to a stable initial state after completing the first test item under the target simulated working condition. This duration is used to ensure that the voltage transformer has completely eliminated the influence of the previous test conditions and recovered to the original performance state before the next test or actual use.

[0084] The second duration refers to the duration of the voltage transformer performing the second test item under the independent simulation working condition. In the embodiment of the present application, it can be understood as the test duration of the voltage transformer under a single specific test condition. This duration is used to ensure that each test item can be fully and accurately evaluated under the independent simulation working condition without being interfered by other factors.

[0085] Obtaining the first duration for the voltage transformer to recover to a normal state after the target simulated working condition, and the second duration for the voltage transformer to recover to a normal state after the independent simulated working condition, respectively, is a key step to improve the overall test efficiency while ensuring the test accuracy. The main purpose of this step is to determine the optimal test sequence by comparing the recovery time under these two different test conditions, thereby maximizing the time efficiency of the test process. In specific implementation, preliminary tests are first required to obtain these two duration data. For the first duration, after completing the comprehensive test under the target simulated working condition, immediately start recording the time required for the voltage transformer to recover to a normal state. This can be achieved by continuously monitoring key parameters (such as voltage ratio, phase angle, etc.) until they return to the predetermined normal range. Similarly, for the second duration, after completing the single test under the independent simulated working condition, the recovery time is also recorded.

[0086] S402: Compare the first duration with the second duration to determine a test sequence of the first test item and the second test item.

[0087] By arranging the test sequence reasonably, the waiting time during the test can be minimized, thereby improving the time efficiency of the test. In specific implementation, it is first necessary to compare the first duration and the second duration data obtained previously. If the first duration is less than the second duration, the first test item under the target simulation condition is arranged first, and then the second test item under the independent simulation condition is arranged. On the contrary, if the second duration is less than the first duration, the second test item under the independent simulation condition is carried out first, and then the first test item under the target simulation condition is carried out. The basis of this sorting method is that the test items with longer recovery time are placed at the back, and the next test can be started immediately after the previous test is completed, without waiting for the voltage transformer to fully recover to the normal state. For example, if the second duration is short, then after completing the independent simulation condition test, the target simulation condition test can be prepared immediately without waiting for a long recovery time. This arrangement of the test sequence not only improves the test efficiency, but also ensures that the voltage transformer is in an appropriate state before each test starts, thereby ensuring the accuracy of the test results.

[0088] Based on the above embodiment, as an optional implementation, it is determined whether there are test items in the comprehensive test results whose test results do not meet the test standards; If there are test items whose test results do not meet the test standards in the comprehensive test results, the test items whose test results do not meet the test standards are determined as target test results, and the improvement parameters of the voltage transformer are determined based on the target test results.

[0089] In the specific implementation, it is first necessary to compare the results of each test item with the pre-set test standards. These standards usually include the allowable range of key parameters such as voltage ratio error, phase angle error, and insulation performance. By using professional data analysis software or manual review, the results of each test item are compared with the corresponding standards one by one. If the results of one or some test items are found to be beyond the allowable range, these items are marked as not meeting the test standards. Subsequently, these test items that do not meet the standards are identified as target test results. These target test results become the focus of subsequent improvement work. By checking and analyzing these factors one by one, the key parameters that affect the performance of the voltage transformer can be determined. These parameters are the so-called improvement parameters. Improvement parameters may include the type of insulating material, the size and material of the core, the number of turns and layout of the coil, etc. After determining these improvement parameters, the design or manufacturing process of the voltage transformer can be adjusted in a targeted manner to improve its performance.
