Description

Technical Field

[0001] The present invention belongs to the field of power grid artificial intelligence technology, and in particular relates to a sulfur hexafluoride monitoring system and a carbon neutrality data processing method based on artificial intelligence. Background Art

[0002] The sources of greenhouse gas emissions from power grid companies include greenhouse gas emissions from electricity production due to transmission and distribution losses and sulfur hexafluoride emissions generated by the use of power equipment. Sulfur hexafluoride GIS equipment is widely used in substations of power grids. Therefore, reducing the leakage and emission of sulfur hexafluoride is crucial for greenhouse gas emission reduction and carbon neutrality of power grid companies.

[0003] When the sulfur hexafluoride equipment in the GIS equipment substation is being repaired, the low pressure alarm and lockout signal of the sulfur hexafluoride density monitor needs to be sent to the protection device to verify the correctness and reliability of the low pressure alarm and lockout signal circuit. When the signal is transmitted, maintenance personnel often use wrench or other tools to push open the self-sealing valve at the equipment's inflation port to deflate, simulating a decrease in pressure to send out a corresponding signal; when deflation, due to poor control of the force, the pressure value in the density gauge does not reach the specified value, and repeated inflation and deflation are required, which not only has low work efficiency, but also can easily damage the sealing of the equipment's self-sealing valve port. In addition, the discharged sulfur hexafluoride gas undergoes high-temperature decomposition in the equipment to form toxic gas, which can easily cause harm to the maintenance personnel carrying out the operation, and the discharged sulfur hexafluoride gas will also pollute the atmosphere and affect the realization of carbon neutrality.

[0004] When constructing or debugging the sulfur hexafluoride equipment of the GIS equipment substation, it is necessary to debug the sulfur hexafluoride density monitor. When using the debugging instrument to connect the sulfur hexafluoride density monitor for debugging, on the one hand, there is a lack of supervision on whether the sulfur hexafluoride gas leaks during the dispatching process. On the other hand, each time the measuring pipeline is plugged in and out during the debugging process, a small amount of sulfur hexafluoride gas in the measuring gas pipe will be discharged into the atmosphere, causing environmental pollution. A small amount of sulfur hexafluoride gas is discharged into the air during the debugging process of each GIS equipment substation. The sulfur hexafluoride gas emissions of multiple GIS equipment substations will cause a large amount of greenhouse gas emissions and damage the carbon neutrality indicators of the power grid. Summary of the invention

[0005] The purpose of the present invention is to provide a sulfur hexafluoride monitoring system and a carbon neutrality data processing method based on artificial intelligence, which solves the problem of lack of supervision of sulfur hexafluoride gas emissions during the maintenance, construction or commissioning of sulfur hexafluoride equipment in GIS equipment substations, and promotes the improvement of greenhouse gas emission reduction and carbon neutrality monitoring level of power grid enterprises.

[0018] Preferably, the first electric valve can be opened or closed to open or close the debugging pipeline.

[0019] Preferably, the debugging pipeline between the first electric valve and the sulfur hexafluoride density monitor is also connected to a recovery pipeline. It can be understood that one end of the recovery pipeline is connected to the debugging pipeline, and the other end of the recovery pipeline is connected to the air inlet of the air pump, and the air outlet of the air pump is connected to the recovery gas cylinder through an air pipe.

[0020] Preferably, the recovery pipeline is located on the side of the first electric valve close to the sulfur hexafluoride density monitor.

[0022] Preferably, the second electric valve can be opened or closed to open or close the recovery pipeline.

[0023] Preferably, the controller includes a debugger unit, a control unit and a communication unit, the control unit communicates with the power grid dispatching center through the communication unit, and the control unit controls the operation of the debugger; the air inlet of the debugger unit is connected to the main pipeline, and the air outlet of the debugger unit is connected to the secondary pipeline; the signal terminal of the sulfur hexafluoride density monitor is also connected to the debugger unit through a signal line. The control unit may include multiple artificial intelligence chips, which can perform on-site image recognition, face recognition and voice recognition, and can also realize voice interaction, and can also perform data encoding, compression, decompression or data analysis and judgment on the received debugging data.

[0026] Preferably, the carbon neutrality data processing method based on artificial intelligence includes the following steps:

[0027] 1) Close the main valve, control valve, auxiliary valve, first electric valve and second electric valve in sequence.

[0028] 2) Connect the sulfur hexafluoride density monitor to the debugging pipeline.

[0029] 3) Connect the signal terminal of the sulfur hexafluoride density monitor to the debugger unit through a signal line.

[0030] 4) Open the first electric valve and close the boost electric proportional valve and the pressure reduction electric proportional valve.

[0031] 5) Open the main valve and control valve in sequence.

[0032] 6) Set the contact action pressure value of the sulfur hexafluoride density monitor to be measured through the debugger unit and start debugging.

[0033] 7) Pressure reduction debugging: The sulfur hexafluoride density monitor is connected to the debugging pipeline, the main pipeline and the auxiliary pipeline normally, and the instrument panel pointer of the sulfur hexafluoride density monitor indicates the working value position. The debugging instrument unit opens the pressure reduction electric proportional valve and the auxiliary valve, and the pressure value of the sulfur hexafluoride density monitor gradually decreases. The auxiliary sulfur hexafluoride gas cylinder stores the gas output by the pressure reduction electric proportional valve. When the pressure drops to the drop threshold, the sulfur hexafluoride density monitor contact acts and is transmitted to the debugging instrument unit through the signal terminal. The debugging instrument unit records the pressure value of the pressure reduction sensor at this time, and the pressure reduction debugging process is completed.

[0034] 8) Boost debugging: Close the step-down electric proportional valve, open the boost electric proportional valve, and the debugger unit drives the boost pump to compress and boost the gas in the auxiliary sulfur hexafluoride gas cylinder and enter the sulfur hexafluoride density monitor through the auxiliary pipeline, main pipeline and debug pipeline. The pressure of the sulfur hexafluoride density monitor gradually increases. When the pressure rises to the boost threshold, the sulfur hexafluoride density monitor contacts actuate and transmit the pressure to the debugger unit through the signal terminal. The debugger unit records the pressure value of the boost sensor at this time to complete the boost debugging process.

[0035] 9) After debugging a sulfur hexafluoride density monitor, close the first electric valve.

[0036] 10) The debugging instrument unit transmits the debugging data to the control unit, and the control unit transmits the debugging data to the power grid dispatching center via the communication unit.

[0037] After receiving the debugging data, the power grid dispatching center transmits instructions to the control unit to start the sulfur hexafluoride gas recovery operation before disassembling the sulfur hexafluoride density monitor, including the following methods:

[0038] Step 11: The control unit detects the pressure of the debugging pipeline, the main pipeline and the auxiliary pipeline. When the pressure is abnormal, the controller issues a voice alarm and reports it to the power grid dispatching center;

[0039] It can be understood that pressure sensors are respectively provided in the debugging pipeline, the main pipeline and the auxiliary pipeline and connected to the control unit to detect the pipeline pressure.

[0040] Step 12, when the pressure detection is normal, open the second electric valve, and the control unit drives the air pump to extract the residual gas in the debugging pipeline between the first electric valve and the sulfur hexafluoride density monitor to the recovery gas cylinder until the pressure indicated by the pointer on the instrument panel of the sulfur hexafluoride density monitor is, and the control unit records the residual gas extraction time, and the control unit reports the number and model of the sulfur hexafluoride density monitor and the residual gas extraction time as the index data of the corresponding control unit to the power grid dispatching center;

[0041] Step 13. The power grid dispatching center is equipped with an artificial intelligence carbon neutrality data training module, which is trained using at least one of machine learning, artificial neural networks, deep learning, convolutional neural networks or recursive neural network algorithms. The power grid dispatching center inputs one or more of the indexed data obtained in the same time period into the artificial intelligence carbon neutrality data training module. When the output value of the artificial intelligence carbon neutrality data training module is normal, the power grid dispatching center controls the control unit of the corresponding indexed data to feedback that the output value is normal.

[0042] It can be understood that the carbon neutrality data training module of artificial intelligence stores standard data on the number and models of different sulfur hexafluoride density monitors and residual gas extraction times through training. When the indexed data deviates from the standard data, the output result is abnormal, otherwise the output value is normal.

[0043] Step 14: The control unit issues a voice prompt indicating that the residual gas recovery is complete and the sulfur hexafluoride density monitor can be removed.

[0044] Beneficial technical effects:

[0045] The residual gas recovery during the commissioning of one or more sulfur hexafluoride density monitors is realized, which improves the efficiency and accuracy of power grid supervision, avoids the generation of greenhouse gases and the decline of the carbon neutrality level of the power grid.

[0052] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention 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 invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. Embodiment 1

[0054] like Figure 1 As shown, during the commissioning of the sulfur hexafluoride density monitor 3 of the power grid GIS equipment substation, the sulfur hexafluoride gas cylinder 1 and the commissioning instrument 21 are usually connected through a pipeline, wherein the sulfur hexafluoride density monitor 3 is detachably connected to the AB section of the pipeline, for example, by screw connection. A valve is provided in the pipeline to close the sulfur hexafluoride gas cylinder 1 and the commissioning instrument 21, but no valve is installed in the AB section of the pipeline. Therefore, when a sulfur hexafluoride density monitor 3 is disassembled after commissioning, the sulfur hexafluoride gas at the AB section will leak, causing the generation of greenhouse gases and a decrease in the carbon neutrality level of the power grid.

[0055] like Figure 2 As shown, a valve is installed at C in the AB section of the pipeline, so that when the sulfur hexafluoride density monitor 3 that has been debugged is replaced, the valve can be used to close the pipeline AB section to prevent leakage of sulfur hexafluoride gas. However, there is a protection blind spot in the AC section of the connecting pipeline between the outside of the valve and the sulfur hexafluoride density monitor 3, which cannot be protected when the sulfur hexafluoride density monitor 3 that has been debugged is replaced, resulting in leakage of sulfur hexafluoride gas, thereby making the pipeline AC section a blind spot for grid carbon neutrality monitoring when debugging the sulfur hexafluoride density monitor 3.

[0056] like Figure 3 and Figure 4 As shown, the sulfur hexafluoride monitoring system includes a sulfur hexafluoride gas cylinder 1, a controller 2, a sulfur hexafluoride density monitor 3, a secondary sulfur hexafluoride gas cylinder 4, an air pump 5, and a recovery gas cylinder 6.

[0067] Preferably, a first electric valve 14 is provided on the debugging pipeline 8 .

[0068] Preferably, the first electric valve 14 can be opened or closed to open or close the debugging pipeline 8 .

[0069] Preferably, the debugging pipeline 8 between the first electric valve 14 and the sulfur hexafluoride density monitor 3 is also connected to the recovery pipeline 9. It can be understood that one end of the recovery pipeline 9 is connected to the debugging pipeline 8, and the other end of the recovery pipeline 9 is connected to the air inlet of the air pump 5. The air outlet of the air pump 5 is connected to the recovery gas cylinder 6 through an air pipe.

[0070] Preferably, the recovery pipeline 9 is located on the side of the first electric valve 14 close to the sulfur hexafluoride density monitor 3 .

[0071] Preferably, a second electric valve 15 is provided on the recovery pipeline 9 .

[0072] Preferably, the second electric valve 15 can be opened or closed to open or close the recovery pipeline 9 .

[0073] Preferably, the controller 2 includes a debugger unit 23, a control unit 22 and a communication unit 24. The control unit 22 communicates with the power grid dispatching center (not shown) through the communication unit 24, and the control unit 22 controls the operation of the debugger unit 23; the inlet end of the debugger unit 23 is connected to the main pipeline 7, and the outlet end of the debugger unit 23 is connected to the auxiliary pipeline 10; the signal terminal of the sulfur hexafluoride density monitor 3 is also connected to the debugger unit 23 through a signal line. The control unit 22 may include multiple artificial intelligence chips, which can perform on-site image recognition, face recognition and voice recognition, and can also realize voice interaction, and can also perform data encoding, compression, decompression or data analysis and judgment on the received debug data.

[0074] Preferably, a first gas circuit and a second gas circuit are provided inside the debugger unit 23, the first gas circuit includes a step-down sensor and a step-down electric proportional valve connected in series, the second gas circuit includes a step-up electric proportional valve, a boost pump and a boost sensor connected in series, and the first gas circuit and the second gas circuit are connected in parallel between the air inlet and the air outlet of the debugger unit 23.

[0075] Preferably, the debugger unit 23 also includes a liquid crystal screen, an undervoltage indicator light, a working indicator light, a charging indicator light, buttons and a debugging operation key.

[0076] Preferably, the carbon neutrality data processing method based on artificial intelligence includes the following steps:

[0077] 1) Close the main valve 11, the control valve 12, the auxiliary valve 13, the first electric valve 14 and the second electric valve 15 in sequence.

[0078] 2) Connect the sulfur hexafluoride density monitor 3 to the debugging pipeline 8.

[0079] 3) Connect the signal terminal of the sulfur hexafluoride density monitor 3 to the debugger unit 23 via a signal line.

[0080] 4) Open the first electric valve 14, and close the boost electric proportional valve and the step-down electric proportional valve.

[0081] 5) Open the main valve 11 and the control valve 12 in sequence.

[0082] 6) Set the contact action pressure value of the sulfur hexafluoride density monitor 3 to be tested through the debugger unit 23 and start debugging.

[0083] 7) Pressure reduction debugging: The sulfur hexafluoride density monitor 3 is normally connected to the debugging pipeline 8, the main pipeline 7 and the auxiliary pipeline 10, and the instrument panel pointer of the sulfur hexafluoride density monitor 3 indicates the working value position. The debugging instrument unit 23 opens the pressure reduction electric proportional valve and the auxiliary valve 13, and the pressure value of the sulfur hexafluoride density monitor 3 gradually decreases. The auxiliary sulfur hexafluoride gas cylinder 4 stores the gas output by the pressure reduction electric proportional valve. When the pressure drops to the drop threshold, the sulfur hexafluoride density monitor 3 contacts actuate and transmit to the debugging instrument unit 23 through the signal terminal. The debugging instrument unit 23 records the pressure value of the pressure reduction sensor at this time, and the pressure reduction debugging process is completed.

[0084] 8) Boost debugging: close the step-down electric proportional valve, open the boost electric proportional valve, the debugger unit 23 drives the boost pump to compress and boost the gas in the secondary sulfur hexafluoride gas cylinder 4 and enter the sulfur hexafluoride density monitor 3 through the secondary pipeline 10, the main pipeline 7 and the debugger pipeline 8. The pressure of the sulfur hexafluoride density monitor 3 gradually rises. When the pressure rises to the boost threshold, the contact of the sulfur hexafluoride density monitor 3 is actuated and transmitted to the debugger unit 23 through the signal terminal. The debugger unit 23 records the pressure value of the boost sensor at this time, completing the boost debugging process.

[0085] 9) After debugging of a sulfur hexafluoride density monitor 3 is completed, the first electric valve 14 is closed.

[0086] 10) The debugging instrument unit 23 transmits the debugging data to the control unit 22 , and the control unit 22 transmits the debugging data to the power grid dispatching center via the communication unit 24 .

[0087] After receiving the debugging data, the grid dispatching center transmits instructions to the control unit 22 to start the sulfur hexafluoride gas recovery operation before disassembling the sulfur hexafluoride density monitor 3, including the following methods:

[0088] Step 11, the control unit 22 detects the pressure of the debugging pipeline 8, the main pipeline 7 and the auxiliary pipeline 10. When the pressure is abnormal, the controller issues a voice alarm and reports it to the power grid dispatching center;

[0089] It can be understood that pressure sensors are respectively provided in the debugging pipeline 8, the main pipeline 7 and the auxiliary pipeline 10 and connected to the control unit to detect the pipeline pressure.

[0090] Step 12, when the pressure detection is normal, open the second electric valve 15, and the control unit 22 drives the air pump 5 to extract the residual gas in the debugging pipeline 8 between the first electric valve 14 and the sulfur hexafluoride density monitor 3 to the recovery gas cylinder 6, until the pressure indicated by the instrument panel pointer of the sulfur hexafluoride density monitor 3 is 0, and the control unit 22 records the residual gas extraction time, and the control unit 22 reports the number and model of the sulfur hexafluoride density monitor 3 and the residual gas extraction time as the indexing data of the corresponding control unit 22 to the power grid dispatching center;

[0091] Step 13. The power grid dispatching center is equipped with an artificial intelligence carbon neutrality data training module, which is trained using at least one of machine learning, artificial neural networks, deep learning, convolutional neural networks or recursive neural network algorithms. The power grid dispatching center inputs one or more of the indexed data obtained in the same time period into the artificial intelligence carbon neutrality data training module. When the output value of the artificial intelligence carbon neutrality data training module is normal, the power grid dispatching center controls the control unit 22 of the corresponding indexed data to feedback that the output value is normal.

[0092] It can be understood that the carbon neutrality data training module of artificial intelligence stores standard data on the number and model of different sulfur hexafluoride density monitors 3 and the residual gas extraction time through training. When the indexed data deviates from the standard data, the output result is abnormal, otherwise the output value is normal.

[0093] Step 14: The control unit 22 issues a voice prompt indicating that the residual gas recovery is complete and the sulfur hexafluoride density monitor 3 can be disassembled. Embodiment 2

[0094] In the first embodiment, during debugging, the residual gas between a sulfur hexafluoride density monitor 3 and the debugging pipeline 8 is monitored and recovered.

[0095] The efficiency of dispatching only one sulfur hexafluoride density monitor 3 at a time is slightly low, and this embodiment makes an improvement.

[0096] like Figure 5 As shown, the debugging pipeline 8 has a plurality of joints on the side away from the main pipeline 7, each of which can be connected to a sulfur hexafluoride density monitor 3, so that the debugging and residual gas recovery of the sulfur hexafluoride density monitor 3 of a GIS interval or a substation can be carried out at one time.

[0097] It can be understood that each debugging pipeline 8 has a closing valve at the joint away from the main pipeline 7 side so as to be closed when not in use.

[0098] After receiving the debugging data, the grid dispatching center transmits instructions to the control unit 22 to start the sulfur hexafluoride gas recovery operation before disassembling the sulfur hexafluoride density monitor 3, including the following methods:

[0099] Step 31, the control unit 22 detects the pressure of the debugging pipeline 8, the main pipeline 7 and the auxiliary pipeline 10. When the pressure is abnormal, the controller issues a voice alarm and reports it to the power grid dispatching center;

[0100] It can be understood that pressure sensors are respectively provided in the debugging pipeline 8, the main pipeline 7 and the auxiliary pipeline 10 and connected to the control unit to detect the pipeline pressure.

[0101] Step 32, when the pressure detection is normal, open the second electric valve 15, and the control unit 22 drives the air pump 5 to extract the residual gas in the debugging pipeline 8 between the first electric valve 14 and the sulfur hexafluoride density monitor 3 to the recovery gas cylinder 6, until the pressure indicated by the instrument panel pointer of each sulfur hexafluoride density monitor 3 is 0, and the control unit 22 records the residual gas extraction time, and the control unit 22 reports the number and model of the sulfur hexafluoride density monitor 3 and the residual gas extraction time as the indexing data of the corresponding control unit 22 to the power grid dispatching center;

[0102] Optionally, the residual gas extraction time can be the time from the start of gas extraction to the time when the pressure indicated by the instrument panel pointer of the last sulfur hexafluoride density monitor 3 is 0 plus the preset time, and the preset time can be 1S, 2S, 3S, 4S, 5S, 1-10S, 1-20S, 1-30S, 5-60S. By setting the preset time, the reliability of residual gas recovery is further increased.

[0103] Step 33. The power grid dispatching center is equipped with an artificial intelligence carbon neutrality data training module, which is trained using at least one of machine learning, artificial neural networks, deep learning, convolutional neural networks or recursive neural network algorithms. The power grid dispatching center inputs one or more of the indexed data obtained in the same time period into the artificial intelligence carbon neutrality data training module. When the output value of the artificial intelligence carbon neutrality data training module is normal, the power grid dispatching center controls the control unit 22 of the corresponding indexed data to feedback that the output value is normal.

[0104] It can be understood that the carbon neutrality data training module of artificial intelligence stores standard data on the number and model of different sulfur hexafluoride density monitors 3 and the residual gas extraction time through training. When the indexed data deviates from the standard data, the output result is abnormal, otherwise the output value is normal.

[0105] Step 34: The control unit 22 issues a voice prompt indicating that the residual gas recovery is complete and the sulfur hexafluoride density monitor 3 can be disassembled.

[0106] Through the above method, the debugging and residual gas recovery of multiple sulfur hexafluoride density monitors 3 can be achieved simultaneously, which not only improves the efficiency but also avoids the generation of greenhouse gases and the decline of the carbon neutrality level of the power grid.
