[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] The discharge measurement method based on the optoelectronic integrated electric field sensor provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the server 102 is connected to the terminal 104 and the photoelectric sensor 106 respectively. The server 102 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal 104 can be, but is not limited to, various personal computers, laptops, smart phones and tablet computers. The photoelectric sensor 106 is a photoelectric sensor based on the Pockels effect.

[0032] Specifically, in response to the discharge measurement instruction for the target discharge device initiated by the terminal 104, the server 102 first performs a performance test on the photoelectric sensor 106 to obtain a performance test result of the photoelectric sensor 106. When the performance test result of the photoelectric sensor 106 reaches the performance threshold, the photoelectric sensor 106 is used to perform a discharge measurement on the target discharge device to obtain an optical signal for the target discharge device output by the photoelectric sensor 106. The server 102 performs signal conversion on the optical signal to obtain a discharge signal of the target discharge device. The discharge signal is subjected to signal analysis to obtain signal changes of the target discharge device in the time dimension and the frequency dimension.

[0033] In an exemplary embodiment, Figure 2 As shown, a discharge measurement method based on a photoelectric integrated electric field sensor is provided. Figure 1 The server 102 in FIG. 1 is used as an example for explanation, including:

[0034] Step S202 , in response to a discharge measurement instruction for a target discharge device, a performance test is performed on a photoelectric sensor to obtain a performance test result of the photoelectric sensor; the photoelectric sensor is a photoelectric sensor based on the Pockels effect.

[0035] Among them, the target discharge device refers to the device that needs to be measured for discharge. The discharge measurement instruction refers to the instruction to perform discharge measurement on the target discharge device. Discharge measurement is to detect the discharge phenomenon that occurs in the target discharge device under the operating state, which can further evaluate its insulation condition and reliability to ensure the normal operation and safe use of the discharge equipment. The Pockels effect refers to the phenomenon that the refractive index of certain crystal materials changes linearly under the action of an external electric field. In other words, the photoelectric sensor is a sensor that uses the electro-optical properties of such crystal materials to measure discharge phenomena. In this embodiment, the crystal material is lithium niobate, which is an electro-optical crystal that can sensitively sense changes in an external electric field. The performance test results can be used to characterize the performance status of the photoelectric sensor. The performance test results can be a specific numerical value, or a percentage, and of course, can also be in the form of a grade.

[0036] For example, when receiving the discharge measurement instruction for the target discharge device initiated by the terminal, the server may first perform a performance test on the photoelectric sensor used for discharge measurement, that is, test the performance of the photoelectric sensor to ensure that the optical signal detected by the photoelectric sensor is sufficiently accurate.

[0037] In one example, a tool specifically for photoelectric sensor performance testing can be used to perform performance testing on the photoelectric sensor. An appropriate testing strategy can also be set according to actual conditions, so that the performance of the photoelectric sensor can be tested according to the testing strategy.

[0038] Step S204, when the performance detection result reaches the performance threshold, the photoelectric sensor is used to perform discharge measurement on the target discharge device to obtain an optical signal output by the photoelectric sensor for the target discharge device.

[0039] The performance threshold may be a reference value pre-defined for the performance test result, a specific value, a specific percentage, or a specific level. When the performance threshold is reached, it can be considered that the current performance of the photoelectric sensor is good and the discharge measurement can be accurately performed. The optical signal refers to the light signal output by the photoelectric sensor. The light signal can be reflected from the electro-optical properties of the crystal material of the photoelectric sensor. That is to say, when the electric field released by the target discharge device acts on the lithium niobate crystal in the photoelectric sensor, the electro-optical properties of the crystal will change, thereby generating a light signal.

[0040] For example, when the server determines that the optical sensor is in good condition, it can instruct the photoelectric sensor to perform discharge measurement on the target discharge device. In this process, the photoelectric sensor can perform non-contact discharge measurement on the target discharge device, effectively avoiding measurement errors caused by contact and ensuring the accuracy of discharge measurement. The lithium niobate crystal on the photoelectric sensor can sense and measure the electric field changes generated by the discharge of the target discharge device with high precision and sensitivity, thereby generating an optical signal.

[0041] Step S206, converting the optical signal to obtain a discharge signal of the target discharge device.

[0042] Among them, signal conversion is the operation of converting optical signals into electrical signals. Discharge signals refer to the electrical signals generated by the target discharge device during the discharge measurement process.

[0043] Exemplarily, after obtaining the optical signal of the target discharge device, the photoelectric sensor may send the optical signal to the server, and the photoelectric conversion unit in the server performs signal conversion, that is, converts the optical signal into an electrical signal.

[0044] In one example, the photoelectric sensor can be connected to the photoelectric conversion unit in the server through an optical fiber, so that the discharge measurement can be realized at a long distance. The photoelectric conversion unit can be a photodiode, which is a semiconductor device that converts light signals into electrical signals. When the light signal is transmitted to the photodiode, the photons are absorbed, causing the electrons to jump from the valence band to the conduction band, thereby generating current.

[0045] Step S208, performing signal analysis on the discharge signal to obtain a signal analysis result of the target discharge device; the signal analysis result is used to characterize the signal change of the discharge signal in the time dimension and the frequency dimension.

[0046] For example, after the photoelectric conversion unit in the server converts the optical signal sent by the photoelectric sensor into an electrical signal, in order to better characterize the discharge signal, the server may further analyze the discharge signal, that is, analyze the changes in the discharge signal in the time dimension and the frequency dimension.

[0047] In one example, the server may perform signal analysis on the discharge signal through an oscilloscope, which is an electronic measuring instrument that can convert electrical signals into visible images, thereby facilitating the study and analysis of the changing processes of various electrical signals.

[0048] In this embodiment, in response to the discharge measurement instruction for the target discharge device, the server first performs a performance test on the photoelectric sensor to ensure the stable operation of the photoelectric sensor and lay the foundation for the subsequent discharge measurement. Then, the photoelectric sensor is tested for performance, and when the performance test of the photoelectric sensor is passed, the photoelectric sensor is used to perform discharge measurement on the target discharge device to obtain an optical signal. It should be noted that the photoelectric sensor is a photoelectric sensor based on the Pockels effect. The Pockels effect is a linear electro-optical effect, and the change in its refractive index is proportional to the magnitude of the applied electric field. This enables the photoelectric sensor based on this effect to measure the weak electric field changes generated by the discharge with high precision, ensuring the accuracy of the discharge measurement. Finally, the optical signal is converted into a discharge signal for multi-dimensional signal analysis to obtain the signal changes of the target discharge device in the time dimension and the frequency dimension, which is conducive to the subsequent maintenance and optimization of the discharge device based on the signal analysis results. Therefore, this embodiment can overcome the current technical defects of inaccurate discharge measurement of power grid equipment and effectively improve the accuracy of discharge measurement.

[0049] In an exemplary embodiment, Figure 3 As shown, a discharge measurement is performed on a target discharge device through a photoelectric sensor to obtain an optical signal output by the photoelectric sensor for the target discharge device, including:

[0050] Step S302: perform corona discharge measurement on a first discharge device by using a photoelectric sensor to obtain a first optical signal output by the photoelectric sensor for the first discharge device.

[0051] Step S304: Perform dielectric barrier discharge measurement on the second discharge device by using a photoelectric sensor to obtain a second optical signal output by the photoelectric sensor for the second discharge device.

[0052] Among them, the target discharge device includes a first discharge device in a corona discharge mode and a second discharge device in a dielectric barrier discharge mode. Corona discharge refers to a local self-sustaining discharge of a gas medium in an inhomogeneous electric field, and dielectric barrier discharge is a non-equilibrium gas discharge with an insulating medium inserted into the discharge space. The optical signal includes a first optical signal for the first discharge device and a second optical signal for the second discharge device. That is, the first optical signal is an optical signal obtained by performing a discharge measurement on a discharge device in a corona discharge mode. The second optical signal is an optical signal obtained by performing a discharge measurement on a discharge device in a dielectric barrier discharge mode.

[0053] Exemplarily, in this embodiment, two discharge phenomena, corona discharge and dielectric barrier discharge, are mainly measured. The optical sensor is used to measure the discharge of the first discharge device in the corona discharge mode and the second discharge device in the dielectric barrier discharge mode, respectively, so as to obtain the optical signals of the two discharge devices.

[0054] In one example, Figure 4 A schematic diagram of the first discharge device in corona discharge mode is shown. It is a pin-plate corona discharge device, with the pin tip located above having a radius of 200µm (micrometers) and a distance of 2cm (centimeter) between the pin tip and the plate electrode located below. The discharge measurement is performed at a frequency of 50HZ (hertz) with a voltage of 8KV (kilovolts) supplied by an AC power supply. A photoelectric sensor can be placed within 1cm of the pin tip to capture changes in the electric field near the device.

[0055] In one example, Figure 5 A schematic diagram of the second discharge device in dielectric barrier discharge mode is shown. A spherical high-voltage electrode is located above and a ground plane is located below. A layer of polytetrafluoroethylene with a thickness of 1 mm is placed between the spherical high-voltage electrode and the ground plane as a dielectric barrier. The discharge measurement is performed by providing a voltage of 12KV through an AC power supply. The photoelectric sensor is also placed within 1 cm of the spherical high-voltage electrode to capture the electric field changes near the device.

[0056] In this embodiment, by performing discharge measurement on the first discharge device in the corona discharge mode and the second discharge device in the dielectric barrier discharge mode, the measurement accuracy of the corona discharge phenomenon and the dielectric barrier discharge phenomenon is improved.

[0057] In an exemplary embodiment, Figure 6 As shown, a discharge measurement is performed on a target discharge device through a photoelectric sensor to obtain an optical signal output by the photoelectric sensor for the target discharge device, including:

[0058] Step S602: performing discharge measurement on a target discharge device through a sensing element of a photoelectric sensor to obtain parameter changes of the sensing element during the discharge process of the target discharge device.

[0059] Step S604: determining the optical signal of the target discharge device based on the parameter change.

[0060] Among them, the sensing element may refer to the electro-optical probe of the photoelectric sensor, and its material is lithium niobate crystal. The electro-optical properties of lithium niobate crystal can be reflected in parameter changes, and parameter changes may refer to changes in the refractive index of lithium niobate crystal. In other words, the electro-optical probe of the photoelectric sensor can sense changes in the electric field. Under the action of the external electric field, the refractive index of the lithium niobate crystal in the electro-optical probe will change. Due to the change in refractive index, the phase of the light wave will also change, thereby forming an optical signal.

[0061] Exemplarily, the photoelectric sensor can be placed near the target discharge device. When the server instructs the photoelectric sensor to perform discharge measurement, the electro-optical probe of the photoelectric sensor senses the corona discharge and / or dielectric barrier discharge of the target discharge device, thereby causing a change in the refractive index of the lithium niobate crystal in the electro-optical probe, thereby causing a change in the phase of a light wave and generating an optical signal.

[0062] In this embodiment, the sensing element, that is, the electro-optical probe, can sensitively sense the change in the electric field, thereby generating a change in the refractive index to determine the optical signal of the target discharge device, thereby improving the accuracy of the discharge measurement.

[0063] In an exemplary embodiment, Figure 7 As shown, the discharge signal is analyzed to obtain the signal analysis result of the target discharge device, including:

[0064] Step S702: Perform continuous wavelet transform on the discharge signal to obtain the time domain characteristics and frequency domain characteristics of the discharge signal.

[0065] Among them, Continuous Wavelet Transform (CWT) is a mathematical tool used to decompose a signal into its constituent wavelets or waveforms. The oscilloscope in step S208 can be an oscilloscope based on continuous wavelet transform. Time domain features describe the characteristics of the discharge signal changing over time, such as waveform features including waveform shape, amplitude, period, etc., statistical features including mean, maximum, minimum, etc., dynamic features including rise time, fall time, etc. Frequency domain features describe the characteristics of the discharge signal at different frequencies, such as spectral components, amplitude spectrum, power spectrum, phase, etc.

[0066] Exemplarily, after obtaining the discharge signal of the target discharge device, the server can perform a continuous wavelet transform on the discharge signal, that is, decompose the discharge signal into wavelets or waveforms, thereby extracting features from the time dimension and frequency dimension respectively, and obtaining the characteristics of the discharge signal that change over time and at different frequencies.

[0067] Step S704: performing signal analysis on the discharge signal based on the time domain characteristics and the frequency domain characteristics to obtain a signal analysis result of the target discharge device.

[0068] Exemplarily, after the server extracts the time domain features and frequency domain features of the discharge signal, it can analyze the discharge signal in the time dimension and the frequency dimension based on the time domain features and the frequency domain features to obtain the signal analysis result of the target discharge device.

[0069] In this embodiment, the discharge signal is subjected to continuous wavelet transform to extract the time domain characteristics and frequency domain characteristics of the discharge signal for signal analysis, thereby ensuring the accuracy of the time domain characteristics and frequency domain characteristics, thereby ensuring the accuracy of the signal analysis, and further improving the accuracy of the entire discharge measurement.

[0070] In an exemplary embodiment, Figure 8 As shown, based on the time domain characteristics and frequency domain characteristics, the discharge signal is analyzed to obtain the signal analysis results of the target discharge device, including:

[0071] Step S802: Based on the time domain characteristics, the discharge signal is analyzed in the time domain to obtain the change trend of the discharge signal of the target discharge device over time.

[0072] Exemplarily, after extracting the time domain features of the discharge signal, the server can perform time domain analysis on the discharge signal based on the time domain features. For example, waveform analysis is to observe the waveform of the discharge signal and analyze its shape, amplitude, period and other characteristics. By comparing the waveforms at different time points, it can be determined whether the discharge signal is stable or has abnormal changes. Trend analysis is to perform statistics and analysis on the changes of the extracted time domain features over time. A chart or trend line can be used to intuitively display the trend of the discharge signal over time. For example, a curve of the peak value of the discharge signal changing over time can be drawn to observe whether it shows an upward trend, a downward trend or a fluctuating trend. Anomaly detection can also be performed to monitor in real time whether there are abnormal discharge signals in trend analysis. Abnormal signals may manifest as sudden peak increases, frequency changes or waveform distortions. These abnormal signals may indicate that the target discharge device is faulty or about to fail.

[0073] Step S804: Based on the frequency domain characteristics, the discharge signal is subjected to frequency domain analysis to obtain the distribution trend of the discharge signal of the target discharge device at different frequencies.

[0074] Exemplarily, after extracting the frequency domain features of the discharge signal, the server can perform frequency domain analysis on the discharge signal based on the frequency domain features. For example, frequency component analysis, that is, observing the spectrum diagram and analyzing the main frequency components contained in the discharge signal. Abnormal frequency components such as high-frequency noise or low-frequency interference can also be identified. Amplitude distribution analysis, that is, analyzing the signal amplitude at different frequencies to understand the intensity distribution of the discharge signal at different frequencies.

[0075] Step S806: taking the distribution trend and the change trend together as the signal analysis result of the target discharge device.

[0076] Exemplarily, the server uses the change trend of the discharge signal of the target discharge device over time and the distribution trend at different frequencies as the signal analysis result of the target discharge device, so that technicians can later maintain the target discharge device based on these signal analysis results.

[0077] In one example, Fig. 9 The signal analysis results of the discharge signal of the first discharge device are shown. During the discharge process, the photoelectric sensor measures that the discharge signal of the first discharge device is in a pulse shape. The pulse amplitude in the positive half cycle is large, and the electric field strength can reach 35 kV / m (kilovolts / meter). The pulse amplitude in the negative half cycle is small, but the number of pulses is large.

[0078] In one example, Fig.10 The signal analysis results of the discharge signal of the second discharge device are shown. Under an AC voltage of 12 kV, the electric field signal captured by the photoelectric sensor shows multiple pulses that appear in both the positive and negative half cycles. The electric field strength is around 78 kV / m. Since the discharge mechanism in dielectric barrier discharge is different from that in corona discharge, the shape, number, and amplitude of the electric field pulses are also different from those under corona discharge.

[0079] In this embodiment, by performing time domain analysis and frequency domain analysis on the discharge signal, the time domain distribution and frequency domain distribution of the discharge signal are better characterized, thereby improving the reliability and accuracy of the signal analysis result and facilitating subsequent maintenance of the target discharge device.

[0080] In an exemplary embodiment, Fig.11 As shown, in response to the discharge measurement instruction for the target discharge device, the photoelectric sensor is subjected to performance detection, and the performance detection result of the photoelectric sensor is obtained, including:

[0081] Step S1102: In response to a discharge measurement instruction for a target discharge device, a discharge measurement requirement indicated by the discharge measurement instruction is obtained.

[0082] The discharge measurement requirement may refer to the requirement information for performing discharge measurement on the target discharge device, such as measurement accuracy, measurement time, measurement efficiency, etc.

[0083] For example, when the server performs performance testing on the photoelectric sensor, it may first parse the discharge measurement instruction to obtain the discharge measurement requirement.

[0084] Step S1104: determine a performance detection index that matches the discharge measurement requirement.

[0085] Among them, the performance detection index may refer to various indicators for performance detection of the photoelectric sensor, such as measurement speed, measurement accuracy, sensitivity, resolution, response time, stability, etc.

[0086] For example, after obtaining the discharge measurement requirement, the server can match the discharge measurement requirement with multiple candidate measurement indicators to select the performance detection indicator that best meets the discharge measurement requirement, thereby performing targeted performance detection on the photoelectric sensor. This can improve the efficiency of performance detection and the accuracy of performance detection.

[0087] Step S1106: Based on the performance detection index, a performance detection is performed on the photoelectric sensor to obtain a performance detection result of the photoelectric sensor.

[0088] Exemplarily, after the server matches the performance detection index, it can perform performance detection on the photoelectric sensor according to each performance detection index, thereby obtaining the performance detection result of the photoelectric sensor.

[0089] In this embodiment, by screening out performance detection indicators that meet the discharge measurement requirements to perform performance detection on the photoelectric sensor, both the efficiency and accuracy of the performance detection can be improved, laying the foundation for subsequent discharge measurement of the target discharge device.

[0090] In a specific embodiment, a discharge measurement method based on a photoelectric integrated electric field sensor includes: when a server receives a discharge measurement instruction for a first discharge device in a corona discharge mode and a second discharge device in a dielectric barrier discharge mode, the server can first parse out the discharge measurement requirements carried by the discharge measurement instruction. Thus, a performance detection index matching the discharge measurement requirements is determined. Based on the performance detection index, a performance detection is performed on a photoelectric sensor based on the Pockels effect to obtain a performance detection result of the photoelectric sensor. When the performance detection result reaches a performance threshold, the first discharge device and the second discharge device are respectively measured by the photoelectric sensor to obtain a first optical signal of the first discharge device and a second optical signal of the second discharge device. The first optical signal and the second optical signal are respectively converted to obtain a discharge signal of the first discharge device and a discharge signal of the second discharge device. Finally, continuous wavelet transform is performed on the discharge signals of the two discharge devices to obtain corresponding time domain features and frequency domain features. Based on each time domain feature, the two discharge signals are respectively analyzed in the time domain to obtain a change trend of the two discharge signals over time. Based on each frequency domain feature, the two discharge signals are analyzed in the frequency domain to obtain a distribution trend of the two discharge signals at different frequencies. The distribution trend and the change trend are used together as the signal analysis result.

[0091] In this embodiment, in response to the discharge measurement instruction for the first discharge device in the corona discharge mode and the second discharge device in the dielectric barrier discharge mode, the server first performs a performance test on the photoelectric sensor to ensure the stable operation of the photoelectric sensor and lay the foundation for the subsequent discharge measurement. Then, the photoelectric sensor is tested for performance, and when the performance test of the photoelectric sensor is passed, the photoelectric sensor is used to perform discharge measurement on the first discharge device and the second discharge device to obtain an optical signal. It should be noted that the photoelectric sensor is a photoelectric sensor based on the Pockels effect. The Pockels effect is a linear electro-optical effect, and the change in its refractive index is proportional to the magnitude of the applied electric field, which enables the photoelectric sensor based on this effect to measure the weak electric field changes generated by the discharge with high precision, ensuring the accuracy of the discharge measurement. Finally, the optical signal is converted into a discharge signal for multi-dimensional signal analysis to obtain the signal changes of the first discharge device and the second discharge device in the time dimension and the frequency dimension, which is conducive to the subsequent maintenance and optimization of the first discharge device and the second discharge device based on the signal analysis results. Therefore, this embodiment can overcome the current technical defect of inaccurate discharge measurement of corona discharge phenomenon and dielectric barrier discharge phenomenon, and effectively improve the measurement accuracy of corona discharge phenomenon and dielectric barrier discharge phenomenon.
