Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power system automation, in particular to a substation switch operation and maintenance inspection method and system. BACKGROUND

[0002] In the power system, as the key node of power transmission and distribution, the stable operation of the substation is crucial. In recent years, with the development of information technology, the substation switch plays an increasingly important role in data transmission, monitoring and control. However, the existing substation switch operation and maintenance inspection technology has certain limitations, and the following is a detailed introduction to the related technical background.

[0003] With the continuous progress of intelligent and networked technology, the operation and maintenance inspection method of substation switch has also been improved. The traditional operation and maintenance inspection mainly relies on manual work, which has the problems of low work efficiency, great safety hidden danger, and incomplete data analysis. To solve these problems, some researchers have proposed an operation and maintenance inspection method based on sensors and monitoring devices, which improves the accuracy of operation and maintenance inspection by collecting real-time state data of the switch. However, these methods still need to be improved in terms of automation, data analysis depth, and inspection efficiency.

[0004] In addition, the operation and maintenance inspection of power communication substation switch is usually carried out remotely, and the inspection personnel remotely log in to the substation switch of the station end to obtain log information, check the running state of the switch, and compare parameters. With the professional knowledge, business ability and experience of the inspection personnel, analysis and judgment are made, which has high skill requirements for the inspection personnel. Different substation switches from different manufacturers and models have different situations, and the instruction sets and syntax features of switches from different manufacturers are also different, so it is not easy for the inspection personnel to master and operate correctly. There is no other special tool for substation switch operation and maintenance inspection. SUMMARY

[0005] In view of the above existing problems, the present application proposes a new operation and maintenance inspection method and system to solve the problems of low automation, incomplete data collection, low inspection efficiency, lack of predictive maintenance, and unreasonable resource allocation in the existing substation switch operation and maintenance inspection technology. Through automatic adaptation of switch instruction sets, comprehensive real-time collection of switch state data, generation of targeted inspection reports, priority inspection of high-risk areas, and implementation of predictive maintenance measures, the present application aims to improve the automation and efficiency of inspection, ensure the stable operation of the switch, and optimize the allocation of inspection resources through intelligent decision support, thereby improving the intelligent and refined level of substation switch operation and maintenance management.

[0006] To solve the above technical problems, a substation switch operation and maintenance inspection method is proposed, which comprises,

[0007] The switch access configuration is performed, the switch instruction set is automatically adapted, the state data of the substation switch is collected in real time through the sensor and the monitoring device to perform the initial operation and maintenance, the inspection report is generated according to the initial operation and maintenance result, the automatic inspection is performed by the multi-body cooperative inspection robot according to the inspection report, the comprehensive analysis is performed according to the collected data and the on-site inspection result, and the operation and maintenance report is generated.

[0008] As a preferred scheme of the substation switch operation and maintenance inspection method, the access configuration comprises connecting the handheld network switch operation and maintenance inspection device with the switch console port through a serial port line, accessing the operation and maintenance inspection state, performing user login and security authentication through the pre-set login information, and automatically adapting the switch instruction set to read the switch configuration.

[0009] As a preferred scheme of the substation switch operation and maintenance inspection method, the initial operation and maintenance comprises collecting the working state data of the substation switch and tracking the physical state data of the switch in real time.

[0010] The working state data comprises flow monitoring data, port state and error rate.

[0011] The physical state data comprises temperature data, power supply state and hardware running state.

[0012] As a preferred scheme of the substation switch operation and maintenance inspection method, the initial operation and maintenance further comprises identifying the abnormal condition of the switch to perform the initial operation and maintenance, and performing real-time flow, temperature and power supply state monitoring analysis behavior mode, including normal mode, overload mode, overheating mode, voltage abnormal mode and serious abnormal mode.

[0013] When the difference between the real-time flow and the normal flow is not more than 10% of the normal flow, the real-time temperature is within the set safe working range, and the real-time voltage is within the set normal voltage range, the system determines the normal mode.

[0014] When the difference between the real-time flow and the normal flow is more than 10% but not more than 30% of the normal flow, the system issues an overload warning, marks a mild overload, and prompts the operator to pay attention to the increase of the flow; when the difference between the real-time flow and the normal flow is more than 30% of the normal flow, the system issues an overload alarm, marks a serious overload, and immediately processes.

[0015] When the real-time temperature exceeds the safety margin of 5 degrees Celsius of the highest safety limit, the system determines the overheating state and prompts to take cooling measures; when the real-time temperature is lower than the safety margin of 5 degrees Celsius of the lowest safety limit, the system determines the low-temperature state and checks the working state of the device.

[0016] When the real-time voltage deviates from the normal voltage by more than a set threshold, the system will determine that the power supply state is unstable, and the power supply equipment is checked in time;

[0017] When the flow is abnormal, but the temperature and voltage are normal, the system determines that the overload mode; when the temperature is out of limit, but the flow and voltage are normal, the system determines that the overheating mode; when the voltage is unstable, but the flow and temperature are normal, the system determines that the voltage abnormal mode; when the flow overload and temperature overheating or power supply abnormality occur at the same time, the system determines that the serious abnormal mode;

[0018] According to different abnormal modes, the operation and maintenance of the expert library and the historical operation and maintenance library are called to perform the initial operation and maintenance of the substation switch, and according to the operation and maintenance result, the abnormal points of the switch are marked before each inspection, the more the number of positions of the abnormality, the larger the number displayed on the screen of the handheld network switch safety inspection device, and when the number exceeds 5, the red warning area is marked.

[0019] As a preferred scheme of the substation switch operation and maintenance inspection method, the inspection report includes generating the inspection report of the multi-body cooperative inspection robot according to the marked number and the red warning area: preferentially inspecting the red warning area, planning a first inspection route for all red warning areas, planning a second inspection route for the marked points other than the red warning areas according to the priority from large to small of the displayed number, marking a yellow area as a position not participating in the inspection on the screen of the handheld network switch safety inspection device after the inspection according to the first inspection route and the second inspection route ends, and planning a third inspection route including all yellow marked areas.

[0020] When the robot is inspecting, the background control personnel operates the buttons on the touch screen of the handheld network switch safety inspection device, including the physical interface state, log query, network port parameter, VLAN parameter, one button corresponds to one operation instruction, when the button is clicked, the state information is queried, the queried data is exported to the handheld network switch safety inspection system, the U disk is inserted into the handheld network switch safety inspection device, and the query result is exported to the U disk.

[0021] As a preferred scheme of the substation switch operation and maintenance inspection method, the inspection route includes that the multi-body cooperative inspection robot calculates the priority order inside the route according to different inspection routes, and divides the area and allocates the task according to the priority inside the route through the multi-body cooperative inspection robot.

[0022] Before each inspection, robots are allocated according to the ratio of 3:2:1 among the first inspection route, the second inspection route, and the third inspection route. If the number of robots is insufficient, they will be allocated to the first inspection route first.

[0023] After the inspection begins, the robot automatically patrols inside and around the substation, monitoring the area status in real time. When the robot inspects any color-coded area or number-marked area, the system automatically or the backend control personnel manually start to query the status information. After the query is completed and the query results are exported, any color-coded area or number-marked area marked green indicates that the inspection has passed. If any area is found not marked green during the inspection, the robot will be re-evaluated and reallocated within 3 minutes to conduct a second inspection of the current route;

[0024] Based on the inspection results, the inspection robot will package the locations of substation switches that have problems more than three times and the exported inspection query results as on-site inspection results and send them to the system's backend control center for comprehensive analysis.

[0025] As a preferred solution of the substation switch operation and maintenance inspection method of the present invention, the comprehensive analysis includes performing a comprehensive analysis based on the collected data and on-site inspection results, and generating an operation and maintenance report;

[0026] The health score of each switch is calculated based on the robot's on-site inspection results. When the score exceeds threshold a, the system considers the current switch to be in good health and maintains real-time status monitoring.

[0027] When the score is lower than threshold a, the system considers the current switch to be in a faulty state and enters the secondary predictive maintenance process. The system predicts the future fault probability and fault severity based on the historical and current data of the current switch, implements predictive maintenance measures, generates an operation and maintenance report, and mines the data of the operation and maintenance report, including historical fault data, time intervals, and impact range. If the incidence of any fault mode in the historical data increases by 30% in the past three months, an operation and maintenance recommendation to adjust the inspection frequency will be added.

[0028] Another object of the present invention is to provide a substation switch operation and maintenance inspection system, which aims to solve technical problems existing in the existing substation switch operation and maintenance inspection, such as low degree of automation, incomplete data collection, low inspection efficiency, lack of predictive maintenance and unreasonable resource allocation.

[0029] As a preferred solution of the substation switch operation and maintenance inspection system described in the present invention, it is characterized by a data acquisition module, an inspection management module, and an analysis and reporting module;

[0031] The inspection management module generates an inspection report according to the preliminary operation and maintenance result, formulates an area to be preferentially inspected by the inspection robot, plans an inspection path, allocates multiple body cooperative inspection robots to automatically inspect according to the planned inspection path, and monitors the inspection state at any time, and packs the on-site inspection result to the analysis report module.

[0032] The analysis report module receives the on-site inspection result provided by the inspection management module, comprehensively analyzes each item of data, calculates the health score of each switch, generates a detailed operation and maintenance report, and proposes a predictive maintenance suggestion.

[0047] Embodiment 1, reference Figures 1-3 As the first embodiment of the present application, the embodiment provides a substation switch operation and maintenance inspection method, comprising:

[0048] S1: Perform switch access configuration, automatically adapt switch instruction set.

[0049] It should be noted that, as Figure 1 shown, the handheld network switch operation and maintenance inspection device is connected with the switch console port through the serial port line, the operation and maintenance inspection state is accessed, the user is logged in and security authentication is performed through the pre-set login information, and the switch instruction set is automatically adapted to read the switch configuration.

[0050] For example, for Swiss Conda switch, the interface state information is as Figure 2 shown.

[0051] S2: Collect the state data of the substation switch in real time to perform initial operation and maintenance through the set sensor and monitoring device.

[0052] It should be noted that the working state data of the substation switch is collected in real time, and the physical state data of the switch is tracked;

[0053] The working state data includes flow monitoring data, port state, error rate;

[0054] The flow monitoring data includes the input and output flow of the switch;

[0055] The port state includes the enabled or disabled state of each port, and the flow load;

[0056] The error rate includes the packet loss rate and the error rate;

[0057] The physical state data includes temperature data, power state, and hardware running state;

[0058] The temperature data includes the working temperature of the switch;

[0059] The power state includes the power supply stability-voltage and current;

[0060] The hardware running state includes the fan speed and the fiber connection status.

[0061] It can be understood that the abnormal situation of the switch is identified for initial operation and maintenance, real-time flow, temperature and power state monitoring and analysis behavior mode, including normal mode, overload mode, overheating mode, voltage abnormal mode and serious abnormal mode;

[0062] When the difference between the real-time flow and the normal flow is not more than 10% of the normal flow, the real-time temperature is within the set safe working range, and the real-time voltage is within the set normal voltage range, the system determines that it is a normal mode;

[0063] When the difference between the real-time flow and the normal flow is more than 10% but not more than 30% of the normal flow, the system issues an overload warning and marks it as mild overload, prompting the operator to pay attention to the increase of flow; when the difference between the real-time flow and the normal flow is more than 30% of the normal flow, the system issues an overload alarm and marks it as serious overload, which is immediately handled;

[0064] When the real-time temperature exceeds the additional 5-degree Celsius safety margin of the highest safety limit, the system determines that it is an overheating state and prompts to take cooling measures; when the real-time temperature is lower than the additional 5-degree Celsius safety margin of the lowest safety limit, the system determines that it is a low-temperature state and checks the working state of the equipment;

[0065] When the real-time voltage deviates from the normal voltage by more than the set threshold, the system will determine that it is an unstable power supply state and check the power supply equipment in time;

[0066] When the flow is abnormal but the temperature and voltage are normal, the system determines that it is the overload mode; when the temperature is out of limit but the flow and voltage are normal, the system determines that it is the overheating mode; when the voltage is unstable but the flow and temperature are normal, the system determines that it is the voltage abnormal mode; when the flow overload and temperature overheating or power supply abnormality occur at the same time, the system determines that it is the serious abnormal mode;

[0067] According to different abnormal modes, the operation and maintenance of the expert library and the historical operation and maintenance library are called for the initial operation and maintenance of the substation switch, and according to the operation and maintenance results, the abnormal points of the switch are marked before each inspection, the more the number of positions of the abnormality appears, the larger the number displayed on the screen of the handheld network switch safety inspection device, and when the number exceeds 5, it is marked as a red warning area.

[0068] S3: generating an inspection report according to the initial operation and maintenance results, and automatically inspecting through the multi-body cooperative inspection robot according to the inspection report.

[0069] It should be noted that the inspection report includes generating the inspection report of the multi-body cooperative inspection robot according to the marked numbers and the red warning area: prioritizing the red warning area, planning the first inspection route for all red warning areas, and planning the second inspection route for the marked points other than the red warning area according to the priority from large to small of the displayed numbers, marking the yellow area as the position not participating in the inspection on the handheld network switch safety inspection device screen after the inspection according to the first and second inspection routes, and planning the third inspection route including all yellow marked areas;

[0070] Wherein, when the robot is inspecting, the background control personnel operates the buttons on the handheld network switch safety inspection device touch screen, including physical interface state, log query, network port parameter, VLAN parameter, one button corresponds to one operation instruction, when the button is clicked, the state information is queried, the queried data is exported to the handheld network switch safety inspection system, the U disk is inserted into the handheld network switch safety inspection device, and the query result is exported to the U disk.

[0071] It should also be noted that the multi-body cooperative inspection robot calculates the internal priority order of the route according to different inspection routes, multiplies the number of red warning areas by a fixed weight, and adds the number marked in each red and yellow warning area to the corresponding weight to obtain the internal priority of the inspection route. The multi-body cooperative inspection robot divides the area and allocates the task according to the internal priority of the different inspection routes;

[0072] When each inspection, the robots are allocated according to the ratio of 3:2:1 of the first, second and third inspection routes, and when the number of robots is insufficient for allocation, the first inspection route is preferentially allocated;

[0073] When starting the inspection, the robot automatically patrols inside and around the substation and monitors the area state in real time, when the robot inspects any color area or number marked area, the system automatically or the background control personnel manually starts to query the state information, after the query is completed and the query result is exported, any color area or number marked area is marked green to indicate that the inspection has passed, when any area is found to be not marked green, the robot is reevaluated and reallocated for secondary inspection of the current route within 3 minutes;

[0074] The inspection robot sends the substation switch position with more than 3 problems and the exported inspection query result to the background control center of the system for comprehensive analysis according to the inspection result.

[0075] S4: According to the collected data and the on-site inspection result, comprehensive analysis is carried out, and an operation and maintenance report is generated.

[0076] It can be understood that the data collected and the on-site inspection results are comprehensively analyzed, and an operation and maintenance report is generated.

[0077] According to the on-site inspection result of the robot, the health score of each switch is calculated, and when the score exceeds the threshold a, the system considers that the health degree of the current switch is good, and the real-time state monitoring is maintained.

[0078] When the score is lower than the threshold a, the system considers that the current switch is in a fault state and enters a secondary predictive maintenance process, the system predicts the future fault probability and fault degree according to the historical data and current data of the current switch, and the predictive maintenance measures are implemented, and an operation and maintenance report is generated. Data mining of the operation and maintenance report includes historical fault data, time interval and influence range, when the occurrence rate of any fault mode in the historical data increases by 30% in the past three months, the operation and maintenance suggestion of increasing the inspection frequency is added.

If any area is found not marked green during the inspection, the robot will be re-evaluated and reallocated within 3 minutes to conduct a second inspection of the current route; Based on the inspection results, the inspection robot will package the locations of substation switches that have problems more than three times and the exported inspection query results as on-site inspection results and send them to the system's backend control center for comprehensive analysis.

4. A substation switch operation and maintenance inspection method according to claim 3, characterized in that: The comprehensive analysis includes conducting a comprehensive analysis based on the collected data and on-site inspection results, and generating an operation and maintenance report; The robot calculates the health score of each switch based on its on-site inspection results. When the score exceeds the threshold, the system considers the switch to be in good health and maintains real-time status monitoring. When the score is lower than the threshold, the system considers the current switch to be in a faulty state and enters the secondary predictive maintenance process. The system predicts the future fault probability and fault severity based on the historical and current data of the current switch, implements predictive maintenance measures, and generates an operation and maintenance report. The data mining of the operation and maintenance report includes historical fault data, time intervals, and impact range. If the incidence of any failure mode in the historical data increases by 30% in the past three months, an operation and maintenance recommendation to adjust the inspection frequency is added.

5. A system using the substation switch operation and maintenance inspection method according to any one of claims 1 to 4, characterized in that: Including data acquisition module, inspection management module, and analysis report module; The data acquisition module connects the handheld network switch operation and maintenance inspection device to the switch console port via a serial cable, and collects status data of the substation switch in real time, including the working status and physical status, monitors and identifies abnormal conditions of the switch in real time, generates preliminary operation and maintenance information, and feeds it back to the inspection management module in real time; The inspection management module generates an inspection report based on the collected preliminary operation and maintenance results, determines the priority inspection areas for the inspection robots, and plans the inspection routes. According to the planned inspection routes, it allocates multiple collaborative inspection robots to conduct automatic inspections, monitors the inspection status at any time, and packages the on-site inspection results to the analysis and reporting module; The analysis and reporting module receives the on-site inspection results provided by the inspection management module, performs a comprehensive analysis of the data, calculates the health score of each switch, and generates a detailed operation and maintenance report, proposing predictive maintenance suggestions.
