Description

Technical Field

[0001] The present invention relates to the technical field of cable fault detection, and in particular to a high-voltage pulse generator simulation method and system for cable fault testing. Background Art

[0002] At present, in the field of cable fault detection, the distance measurement link of the cable fault traveling wave method must use a high-voltage pulse generator to apply a high-voltage pulse to the faulty cable to fully discharge the fault point, thereby forming a reflected wave, and the waveform analysis is performed through the cable fault distance meter to accurately test the location of the fault point. However, for beginners in this industry, the traditional way of learning is to directly use high-voltage pulse equipment for learning and operation, but the construction of a high-voltage test environment is a large amount of engineering work and the adaptability to fault distance and fault type is limited. In addition, the high-voltage pulse generator will easily output a high voltage of several thousand volts or tens of kilovolts. As a result, for learners, once an error occurs, there will be a great safety hazard invisibly.

[0003] Chinese patent, publication number: CN222106109U, publication date: December 3, 2024, discloses a power cable fault simulation device, which generates high-voltage pulse signals during cable fault testing through a high-voltage wiring operation panel, a discharge box, and a high-voltage line module group. It can simulate short circuit, open circuit, flashover or high-resistance faults, and is used to learn the high-voltage flashover method and multiple pulse method to test waveforms of different faults at different distances. However, during the learning process of students, it still generates corresponding high-voltage pulse signals, and it can easily output high voltages of several thousand volts or tens of kilovolts. In this way, for students, once an incorrect operation occurs, there will be a great safety hazard invisibly. Summary of the invention

[0004] In view of the problem that the current learning of cable fault testing requires direct use of high-voltage pulse equipment for learning and operation, which poses a high safety hazard, the present invention provides a high-voltage pulse generator simulation method and system for cable fault testing. By configuring the required test tools and test environment according to the test requirements in advance and saving the preset test environment, the test environment can be directly selected during learning, which reduces the amount of engineering required for building a high-voltage test environment, thereby improving learning efficiency. During testing, by generating a simulation signal and executing the action of the test tool under the action of the high-voltage pulse generator through the simulation signal, there is no need to output a real high-voltage pulse. Only the signal characteristics of the simulation signal need to be adjusted to equivalently implement a series of operations for cable fault detection under high-voltage pulses, which greatly improves the personal safety of trainees. At the end of the test, a comprehensive evaluation is also made on the trainees' operating steps and test results, which is convenient for trainees to find their own deficiencies and conduct targeted learning to improve learning effects.

[0005] In a first aspect, a technical solution provided in an embodiment of the present invention is: a high voltage pulse generator simulation method for cable fault testing, comprising the following steps: S1. Generate a pulse configuration file based on the test requirements, and send the pulse configuration file to the scene setting module, and synchronously generate a cable fault test rule; S2, the scene setting module reads the pulse configuration file and calls the scene model library to generate a high-voltage pulse test scene; S3, the operation module executes the cable fault detection process in the high-voltage pulse test scenario based on the test requirements and generates a first detection signal, and the action module generates a corresponding pulse action based on the signal characteristics of the first detection signal; S4. Record the second detection signal generated by the cable in response to the pulse action in the cable fault detection process, and the action module generates a corresponding detection action based on the signal characteristics of the second detection signal; compare the detection action and the pulse action with the cable fault test rules respectively and obtain a test score in combination with the comprehensive evaluation principle.

[0006] In this solution, a pulse configuration file is automatically generated based on the test requirements and automatically sent to the scene setting module. During the test, you only need to select the corresponding test environment according to the test requirements, without spending a lot of energy to build a complex high-voltage test environment, which greatly reduces the time of manual configuration, thereby improving the test efficiency and further simplifying the test preparation process. The corresponding pulse action and detection action are generated by the signal characteristics of the first detection signal and the second detection signal, and the action generated by the test tool under the action of the high-voltage pulse generator is executed by generating an analog signal and using the analog signal. There is no need to output a real high-voltage pulse. Only the signal characteristics of the analog signal need to be adjusted to equivalently realize a series of operations for cable fault detection under high-voltage pulses, thereby avoiding the risk of high-voltage electric shock caused by trainees' misoperation, greatly improving the personal safety of trainees, and at the end of the test, a comprehensive evaluation of the trainees' operating steps and test results is also conducted, which is convenient for trainees to find their own shortcomings and conduct targeted learning to improve learning effects.

[0007] Preferably, the contents of the pulse configuration file at least include a test mode, a cable fault type and a pulse output action library; The cable fault types include at least short circuit fault, open circuit fault and high resistance fault.

[0008] In this scheme, the traveling wave method is used for cable fault testing. High-voltage pulses are applied to the cable to fully discharge the fault point, thereby forming a reflected wave. The waveform of the reflected wave is then detected to accurately locate the fault point. Therefore, the test modes are all set based on the traveling wave method. The cable fault types include most of the common faults, which are sufficient to meet the daily learning needs of students.

[0009] Preferably, the scenario model library includes at least an environment model library and a test tool model library; the environment model library includes at least an environment simulation data model composed of weather, buildings, temperature and humidity; the test tool model library includes at least a test tool simulation data model composed of a pulse output device model, a voltage detection device model and a control device model.

[0010] In this scheme, when using the traveling wave method to test cable faults, a variety of test tools are needed. Therefore, in the scenario model library, when students select the corresponding test mode, the corresponding test tools can be automatically generated. By operating the test tools to perform fault tests on the cables, students can have a full understanding of the real test tools in a simulated environment, thereby improving their testing experience.

[0011] Preferably, in S3, the operation module executes the cable fault detection process in the high voltage pulse test scenario based on the test requirements and generates a first detection signal, including the following steps: The operation module sets a test mode based on a test requirement, selects a corresponding cable fault detection process based on the test mode, and generates a corresponding first detection signal based on the cable fault detection process.

[0012] In this scheme, in order to realize the cable fault test process under the action of high-voltage pulse signal without generating high-voltage pulse signal in the cable fault test, the signal characteristics such as signal amplitude, period and pulse size of the analog signal are adjusted to control the test tool to make corresponding actions, thereby avoiding the risk of high-voltage electric shock caused by trainees' misoperation and ensuring the safety of trainees' lives.

[0013] Preferably, in S3, the action module generates a corresponding pulse action based on the signal feature of the first detection signal, including the following steps: The action module performs signal feature analysis on the first detection signal to obtain a first signal feature factor, standardizes the first signal feature factor to obtain a feature value of each feature factor, and compares the feature value with the total feature value of the first signal feature factor to obtain a weight of each feature factor; Based on the weight of each characteristic factor, a corresponding pulse action is selected from the pulse output action library and executed.

[0014] In this solution, in order to match the first detection signal with the pulse action performed by the corresponding test tool, the signal characteristics of the first detection signal are analyzed to obtain the first signal characteristic factor. Different pulse actions have different and unique signal characteristics of the analog signal corresponding to them. Therefore, it is only necessary to split, arrange and match the signal characteristics of the first detection signal to quickly find the corresponding pulse action, thereby improving the response speed during cable fault testing to improve test efficiency.

[0015] Preferably, the pulse actions stored in the pulse output action library include at least high-voltage opening action, high-voltage closing action, single pulse output action, periodic pulse output action and synchronous rising and falling action of the voltmeter pointer.

[0016] In this solution, during the cable testing process, the high-voltage pulse signal is mainly used to fully discharge the cable fault point. Under the action of the high-voltage pulse, the corresponding test tool will perform a series of actions. In order to ensure that the cable testing process can be implemented normally, the possible actions are preset and saved. During the test, the corresponding action is selected from the pulse output action library to ensure that the test process is accurate.

[0017] Preferably, selecting and executing a corresponding pulse action from a pulse output action library based on the weight of each characteristic factor comprises the following steps: The weight of each characteristic factor is substituted into a preset pulse action evaluation index system to obtain the pulse action value of the first detection signal, and the pulse action corresponding to the first detection signal is determined based on the pulse action value.

[0018] In this scheme, by substituting the weight of each characteristic factor into the preset pulse action evaluation index system, the pulse action value that best matches the current situation can be accurately calculated, ensuring that the selected pulse action is based on a comprehensive consideration of all relevant characteristic factors, thereby improving the accuracy and applicability of the action, thereby ensuring that the cable fault simulation test can be carried out normally without a real high-voltage pulse signal.

[0019] Preferably, the evaluation indexes in the pulse action evaluation index system at least include signal amplitude, signal period and signal pulse number.

[0020] In this scheme, since different analog signals are mainly distinguished by signal characteristics such as signal amplitude, signal period and signal pulse number, in the pulse action evaluation index system, in order to have an accurate evaluation of the analog signal, the pulse action evaluation index is constructed according to the type of signal characteristics, thereby ensuring the recognition accuracy of the analog signal and improving the matching accuracy of the pulse action.

[0021] Preferably, in S4, the detection action and the pulse action are compared with the cable fault test rules respectively and combined with the comprehensive evaluation principle to obtain a comprehensive test score, including the following steps: The detection action is compared with the cable fault test rules to obtain the test result score, the pulse action is compared with the cable fault test rules to obtain the operation step score, the preset weights of the operation step score and the test result score are set, and the weighted sum of the operation step score and the detection result score is performed based on the preset weights to obtain the comprehensive test score.

[0022] In this scheme, by taking the weighted sum of the operation step scores and the test result scores, the students' operation ability and detection ability are comprehensively evaluated. This can prevent the situation where the student's comprehensive evaluation is inconsistent with the student's own ability due to excessively high scores in one aspect, making the comprehensive test score more reliable.

[0023] In a second aspect, a technical solution provided in an embodiment of the present invention is: a high-voltage pulse generator simulation system for cable fault testing, comprising a pulse setting module, a scene setting module, a simulation signal generation module, an action module and an evaluation module; The pulse setting module generates a pulse configuration file based on the test requirements and generates a cable fault test rule; The scene setting module is used to call the scene model library and build a high-voltage pulse test scene based on the pulse configuration file; The analog signal generation module executes the cable fault detection process based on the test requirements and generates a first detection signal, and generates a corresponding pulse action through the action module; the analog signal generation module synchronously records the second detection signal generated by the cable in response to the pulse action, and generates a corresponding detection action through the action module; The evaluation module compares the detection action and the pulse action with the cable fault test rules respectively and obtains a comprehensive test score in combination with the comprehensive evaluation principle.

[0024] In this solution, by replacing the control unit, high-voltage step-up transformer unit, and high-voltage energy storage capacitor in the traditional high-voltage pulse generator, the high-voltage pulse generator can realize high-voltage opening action, high-voltage closing action, single pulse output action, and periodic pulse output action by changing the analog signal, and realize the synchronous rise and fall of the voltmeter pointer during the lifting and lowering of the boost knob, and the discharge device is activated during the pulse output; it can be synchronized with the cable fault simulation test system to output flashover and multiple signals, which is convenient for the fault waveform sampling and analysis and training and teaching of the cable fault tester. At the same time, it aims at helping learners master the operation and characteristics of the equipment in the process of learning cable fault testing, and there is no high voltage signal. When operating the high-voltage pulse generator, the high-voltage electric shock hazard caused by the trainee's misoperation is avoided, thereby reducing the risk of personal electric shock to zero and ensuring the life safety of the trainees.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention automatically generates a pulse configuration file based on the test requirements and automatically sends it to the scene setting module. During the test, it is only necessary to select the corresponding test environment according to the test requirements, without spending a lot of energy to build a complex high-voltage test environment, which greatly reduces the time for manual configuration, thereby improving the test efficiency and further simplifying the test preparation process; (2) The corresponding pulse action and detection action are generated by the signal characteristics of the first detection signal and the second detection signal. An analog signal is generated and used to execute the action generated by the test tool under the action of the high-voltage pulse generator. There is no need to output a real high-voltage pulse. Only the signal characteristics of the analog signal need to be adjusted to equivalently implement a series of operations for cable fault detection under high-voltage pulses, thereby avoiding the risk of high-voltage electric shock caused by trainees' misoperation and greatly improving the personal safety of trainees.

[0033] In this embodiment, the traveling wave method is used for cable fault testing. High-voltage pulses are applied to the cable to fully discharge the fault point, thereby forming a reflected wave. The waveform of the reflected wave is then detected to accurately locate the fault point. Therefore, the test modes are all set based on the traveling wave method. The cable fault types include most of the common faults, which are sufficient to meet the daily learning needs of students.

[0034] S2: The scenario setting module reads the pulse configuration file and calls the scenario model library to generate a high-voltage pulse test scenario.

[0036] In this embodiment, when the traveling wave method is used to test cable faults, a variety of test tools are required. Therefore, in the scenario model library, when the trainee selects the corresponding test mode, the corresponding test tool can be automatically generated. By operating the test tool to perform fault testing on the cable, the trainee can have a full understanding of the real test tools in a simulated environment, thereby improving the trainee's testing experience.

[0037] S3: The operation module executes the cable fault detection process in the high-voltage pulse test scenario based on the test requirements and generates a first detection signal, and the action module generates a corresponding pulse action based on the signal characteristics of the first detection signal.

[0038] In this embodiment, the operation module executes the cable fault detection process in the high voltage pulse test scenario based on the test requirements and generates a first detection signal, including the following steps: The operation module sets a test mode based on a test requirement, selects a corresponding cable fault detection process based on the test mode, and generates a corresponding first detection signal based on the cable fault detection process.

[0039] In order to realize the cable fault test process under the action of high-voltage pulse signals without generating high-voltage pulse signals in the cable fault test, this embodiment controls the test tool to perform corresponding actions by adjusting the signal characteristics of the analog signal such as signal amplitude, period and pulse size, thereby avoiding the risk of high-voltage electric shock caused by trainees' misoperation and ensuring the safety of trainees' lives.

[0040] In this embodiment, the action module generates a corresponding pulse action based on the signal characteristics of the first detection signal, including the following steps: The action module performs signal feature analysis on the first detection signal to obtain a first signal feature factor, standardizes the first signal feature factor to obtain a feature value of each feature factor, and compares the feature value with the total feature value of the first signal feature factor to obtain a weight of each feature factor; Based on the weight of each characteristic factor, a corresponding pulse action is selected from the pulse output action library and executed.

[0041] In order to match the first detection signal with the pulse action performed by the corresponding test tool, this embodiment analyzes the signal characteristics of the first detection signal to obtain the first signal characteristic factor. Different pulse actions have different and unique signal characteristics of the analog signal corresponding to them. Therefore, it is only necessary to split, arrange and match the signal characteristics of the first detection signal to quickly find the corresponding pulse action, thereby improving the response speed during cable fault testing to improve the test efficiency.

[0042] In this embodiment, the pulse actions stored in the pulse output action library at least include high-voltage opening action, high-voltage closing action, single pulse output action, periodic pulse output action and synchronous rising and falling action of the voltmeter pointer.

[0043] In the cable testing process of this embodiment, the high-voltage pulse signal is mainly used to fully discharge the cable fault point. Under the action of the high-voltage pulse, the corresponding test tool will perform a series of actions. In order to ensure that the cable testing process can be implemented normally, the possible actions are preset and saved. During the test, the corresponding action is selected from the pulse output action library to ensure that the test process is accurate.

[0044] In this embodiment, selecting and executing a corresponding pulse action from a pulse output action library based on the weight of each characteristic factor includes the following steps: The weight of each characteristic factor is substituted into a preset pulse action evaluation index system to obtain the pulse action value of the first detection signal, and the pulse action corresponding to the first detection signal is determined based on the pulse action value.

[0045] This embodiment can accurately calculate the pulse action value that best matches the current situation by substituting the weight of each characteristic factor into the preset pulse action evaluation index system, ensuring that the selected pulse action is based on a comprehensive consideration of all relevant characteristic factors, thereby improving the accuracy and applicability of the action, thereby ensuring that the cable fault simulation test can be performed normally without a real high-voltage pulse signal.

[0046] In this embodiment, the evaluation indexes in the pulse action evaluation index system at least include signal amplitude, signal period and signal pulse number.

[0047] In this embodiment, since different analog signals are mainly distinguished by signal characteristics such as signal amplitude, signal period and signal pulse number, in the pulse action evaluation index system, in order to have an accurate evaluation of the analog signal, the pulse action evaluation index is constructed according to the type of signal characteristics, thereby ensuring the recognition accuracy of the analog signal and improving the matching accuracy of the pulse action.

[0048] S4. Record the second detection signal generated by the cable in response to the pulse action in the cable fault detection process, and the action module generates a corresponding detection action based on the signal characteristics of the second detection signal; compare the detection action and the pulse action with the cable fault test rules respectively and obtain a test score in combination with the comprehensive evaluation principle.

[0049] In this embodiment, the detection action and the pulse action are compared with the cable fault test rules respectively and combined with the comprehensive evaluation principle to obtain a comprehensive test score, including the following steps: The detection action is compared with the cable fault test rules to obtain the test result score, the pulse action is compared with the cable fault test rules to obtain the operation step score, the preset weights of the operation step score and the test result score are set, and the weighted sum of the operation step score and the detection result score is performed based on the preset weights to obtain the comprehensive test score.

[0050] This embodiment comprehensively evaluates the student's operating ability and detection ability by weighted summing up the operation step score and the test result score, which can prevent the situation where the student's comprehensive evaluation is inconsistent with the student's own ability due to excessively high scores in one aspect, making the comprehensive test score more reliable.

[0051] Example 2: Figure 2 As shown, this embodiment also provides a high-voltage pulse generator simulation system for cable fault testing, including a pulse setting module, a scene setting module, a simulation signal generation module, an action module and an evaluation module; The pulse setting module generates a pulse configuration file based on the test requirements and generates a cable fault test rule; The scene setting module is used to call the scene model library and build a high-voltage pulse test scene based on the pulse configuration file; The analog signal generation module executes the cable fault detection process based on the test requirements and generates a first detection signal, and generates a corresponding pulse action through the action module; the analog signal generation module synchronously records the second detection signal generated by the cable in response to the pulse action, and generates a corresponding detection action through the action module; The evaluation module compares the detection action and the pulse action with the cable fault test rules respectively and obtains a comprehensive test score in combination with the comprehensive evaluation principle.

[0052] like Figure 3 As shown, the single-chip microcomputer is used as the main control board of this embodiment, and the operation panel is used as the pulse setting module and scene setting module of this embodiment. Before testing, the corresponding functions are set on the operation panel, including the closing button state, the opening button state, the discharge mode (including manual discharge and automatic discharge), the number of pulses (including single and secondary), the voltmeter and the voltage gear. After the setting is completed, the signal interaction is carried out with the cable fault simulation test system through the wireless transmission module, and the cable fault simulation system is associated with the high-voltage pulse generator simulation system. The size of the output signal is controlled by the discharge rotating device, and the signal is output through the signal output module, thereby realizing the analog output of the high-voltage pulse signal.

[0053] This embodiment replaces the control unit, high-voltage step-up transformer unit, and high-voltage energy storage capacitor in the traditional high-voltage pulse generator, and controls the high-voltage pulse generator through a single-chip computer program, so that the high-voltage pulse generator can realize high-voltage opening action, high-voltage closing action, single pulse output action, and periodic pulse output action, and realize the synchronous rise and fall of the voltmeter pointer during the lifting and lowering of the boost knob. When the pulse is output, the discharge device is actuated, and synchronized with the functional state of the simulated fault signal generator through the wireless synchronization module, so that when a single pulse occurs, the simulated fault signal generator sends a single pulse signal, and when a periodic pulse occurs, the simulated fault signal generator sends a periodic pulse signal; when a secondary pulse occurs, the simulated fault signal generator sends a periodic pulse signal, and at the same time, it is synchronized with the functional state of the cable fault simulation system to output flashover and multiple signals, which is convenient for the fault waveform sampling and analysis and training and teaching of the cable fault tester.

[0054] It can be seen from the above embodiments that at least the following substantial effects are achieved: (1) The present invention automatically generates a pulse configuration file based on the test requirements and automatically sends it to the scene setting module. During the test, only the corresponding test environment needs to be selected according to the test requirements, without spending a lot of energy to build a complex high-voltage test environment, which greatly reduces the time of manual configuration, thereby improving the test efficiency and further simplifying the test preparation process; (2) The corresponding pulse action and detection action are generated by the signal characteristics of the first detection signal and the second detection signal. An analog signal is generated and used to execute the action generated by the test tool under the action of the high-voltage pulse generator. There is no need to output a real high-voltage pulse. Only the signal characteristics of the analog signal need to be adjusted to equivalently implement a series of operations for cable fault detection under high-voltage pulses, thereby avoiding the risk of high-voltage electric shock caused by trainees' misoperation and greatly improving the personal safety of trainees.
