[0002] The safe and stable operation of substations is one of the prerequisites for ensuring the order of social production activities. Therefore, the efficiency and accuracy of the confirmation of substation fault information are crucial. For example, when an accident or abnormality occurs in a substation, it is necessary to quickly and accurately collect secondary fault information in order to analyze the cause of the accident and restore power supply in time.

[0003] At present, the secondary information is collected manually. For example, when an accident or abnormality occurs in a substation, the power workers stationed at the substation collect the secondary fault information. However, there are many types of power equipment and the operation is highly professional. If the skill level of the power workers is not high, the comprehensiveness and accuracy of the collected secondary fault information will be limited, which will affect the fault cause analysis results and fault repair work of the substation. Secondly, if the substation is unattended, the effectiveness of the secondary fault information cannot be guaranteed, which will delay the progress of the fault cause analysis and repair progress of the substation, and even affect the operation of the substation and social production activities.

[0029] Figure 1 This is a flow chart of a method for determining fault information of a substation provided by the present invention. This embodiment can be applied to the situation of determining secondary distributed information of faults of a substation quickly, efficiently, safely and with low resource consumption. The method can be executed by the device for determining fault information of a substation provided by the present invention. The device can be implemented in the form of hardware and / or software. In a specific embodiment, the device can be integrated in an electronic device. The following embodiments will be described by taking the device integrated in an electronic device as an example. Figure 1 , the method specifically comprises the following steps:

[0030] S101. Determine a secondary information collection task of the substation based on initial fault information of the substation.

[0031] The central processing unit can be linked to a variety of information acquisition equipment such as the Supervisory Control And Data Acquisition (SCADA), the power grid management platform information system, and the substation surrounding environment monitoring system to regularly obtain the operating data of each substation in its management area, including but not limited to the current, voltage, temperature, alarm information of the monitoring equipment, the secondary protection setting information in the CADA system, and the equipment ledger information such as the name, model, installation location, and operating status. If there is an abnormality in the substation, the operating data of the substation will contain abnormal operating data, and the initial fault information of the substation can be understood as the abnormal operating data in the information obtained by the above central processing unit, for example, data that does not conform to the preset operating rules, abnormal alarm information, device abnormal information, etc. In order to ensure the accuracy of the substation abnormal monitoring, the present invention will perform secondary detection on the equipment with abnormal operating data, that is, it will obtain the operating data of the equipment corresponding to the initial fault information for a second time. The advantage of such a setting is that more detailed and more real-time abnormal information can be obtained, reducing the probability of information omission, thereby ensuring the comprehensiveness and accuracy of the substation fault information. The secondary information collection task can be understood as the equipment and collection requirements for secondary information collection. The secondary information collection task includes at least one device to be collected, and the equipment to be collected includes but is not limited to the protection screen, fault recording screen, pressure plate, circuit breaker and handle in the substation.

[0032] The advantage of this setting is that the equipment that needs to be inspected a second time can be quickly determined based on the initial fault information in the substation operation information, that is, the secondary information collection location, which greatly improves the efficiency of obtaining secondary information.

[0033] The present invention uses machine learning and pattern recognition technology to train a data analysis model in advance. The data analysis model is loaded on the central processing unit. On the one hand, it is used to analyze the fault interval information, fault time information and protection action information of the substation according to the initial fault information, and then determine the equipment that needs to be secondary detected, that is, the equipment corresponding to the secondary scattered information (fault secondary information that needs to be collected again). On the other hand, it is used to process the initial fault information and the secondary scattered information, analyze the causes and influencing factors of the fault, and make a judgment and evaluation of the fault situation. At this time, the work of the data analysis model is to integrate and unify the collected secondary scattered information including device status, alarm information and action records, and then combine external data, initial fault information and secondary scattered information for correlation analysis to determine the relevant parameters and conditions when the fault occurs. The advantage of such a setting is that it can comprehensively consider the external data and secondary scattered information, comprehensively analyze the causes and influencing factors of the fault, and make accurate fault judgments and evaluations. External data can be understood as non-relay protection secondary accident-related factors obtained by other platforms, such as work ticket construction work information (construction causes equipment failure), weather factors (bad weather causes equipment failure), other accident event information (failures in other areas cause local failures), etc. This embodiment does not limit this.

[0034] In one embodiment, S101 may specifically include: determining the fault interval information, fault time information, fault type and protection action information of the substation based on the initial fault information; determining at least one device to be collected based on the fault interval information, fault time information and protection action information.

[0035] Among them, the fault interval information can be understood as the interval length of each abnormal operation data in the initial fault information, the fault time information can be understood as the generation time of each abnormal operation data, and the protection action information can be understood as the alarm information of each device in the substation. The fault interval information, fault time information, fault type and protection action information can be used as data support for parsing the equipment that needs secondary detection. The equipment to be collected can be understood as the equipment that needs secondary detection, that is, the equipment where the secondary dispersed information is located.

[0036] Specifically, based on the abnormal data (initial fault information) in the data information stored by the background monitoring machine, the interval, time and protection action of the accident can be known. Basic rules are set in the data analysis model. For example, the corresponding protection screen that needs to be further searched for the interval A fault is A+B, and the corresponding protection screen that needs to be searched for the interval B fault is C+D. Additional rules can also be set. For example, if a DC grounding occurs during the fault, it is necessary to find the protection screen E, and if a thunderstorm occurs during the fault, it is necessary to find the protection screen F, etc. By superimposing special situations on different intervals, the screen cabinets (devices to be collected) for which data need to be collected can be obtained.

[0037] It is worth noting that before determining the fault interval information, fault time information and protection action information of the substation based on the initial fault information, the initial fault information will be cleaned and preprocessed, including but not limited to data denoising, outlier processing and data normalization. The advantage of this setting is to ensure the data quality and accuracy of the initial fault information and improve the accuracy of the fault interval information, fault time information and protection action information.

[0038] S102: Determine an information collector to be operated and first control information of the information collector to be operated based on location information of at least one device to be collected.

[0039] The location information of the device to be collected can be understood as the location of the device to be collected in the substation, the information collector to be operated can be understood as a robot or information collection device that needs to perform a secondary decentralized information collection task, and the first control information can be understood as the operation instruction information of the information collector to be operated in the process of performing the information collection task, including but not limited to the collection target, operation route, driving speed information and stop information. The information collector to be operated includes at least one information collection robot, and the first control information includes at least one sub-control information, and the information collection robot corresponds to the sub-control information one by one.

[0040] Specifically, there may be multiple devices to be collected. If the distance between multiple devices to be collected is close, only one robot needs to be started to quickly complete the information collection task. If the distance between the devices to be collected is far, the devices to be collected need to collect a lot of secondary information, or the operation of the devices to be collected is more complicated, in order to ensure the efficiency of information collection, multiple robots need to be started to perform the information collection tasks separately. The sub-control information is the operation instruction information of each robot.

[0041] The advantage of this setting is that it can combine the location information of the equipment to be collected in the substation and the attribute information of the information collector, and specifically determine the information collector to be operated, thereby ensuring the quality and efficiency of information collection while reducing resource consumption.

[0042] Furthermore, the present invention determines the priority of tasks according to the type and severity of the fault to ensure that critical tasks can be responded to and processed in a timely manner, that is, a task allocation strategy is designed to allocate high-priority tasks to the robots or devices that respond first and have higher functional levels, so as to achieve effective execution and collaborative work of tasks.

[0043] In one embodiment, S102 may specifically include: determining an initial operation information collector, location information and type information of the initial operation information collector, wherein the initial operation information collector includes at least one information collection robot; based on the location information of at least one device to be collected and the location information and type information of each information collection robot in the initial operation information collector, determining the information collector to be operated and the first control information, wherein the first control information includes the collection target, operation route, driving speed information and stop information of the information collector to be operated.

[0044] The robots in the substation include information collection robots, fault report printing robots, etc. Different robots perform different types of tasks, and only information collection robots can perform information collection tasks. Therefore, when obtaining secondary fault information, it is necessary to determine the information collector to be operated and its first control information based on the position of each information collection robot and the position information of the equipment to be collected. The advantage of this setting is that a better, lower resource consumption, and more efficient information collection strategy can be formulated based on the position of each information collection robot.

[0045] Specifically, the information collection device and the device to be collected can also be associated, and the information collector to be operated and its first control information can be determined according to the association relationship. In one embodiment, it is assumed that the devices for storing key accident event information in the substation are A, B, C, D, E, F, etc., and different protection screen cabinets are in different spaces. Different robots are arranged in different spaces, for example, relay room robots, communication room robots, outdoor robots, outdoor robots, etc. The default configuration has a way to obtain associated key information. For example, devices A and B need to be obtained by robot 1 (communication room robot), devices C and D need to be obtained by robot 2 (outdoor robot), and devices E and F need to be obtained by robot 3 (indoor robot). If the data analysis model determines that the protection screen cabinets for the key information to be found are A, B, and C, a task is sent to robots 1+2 to obtain secondary fault information.

[0046] S103: Control the to-be-run information collector to run based on the first control information to collect secondary fault information of at least one device to be collected.

[0047] Specifically, controlling the information collector to be operated to collect the secondary fault information of at least one device to be collected based on the first control information can be understood as controlling each information collection robot to operate based on its corresponding sub-control information to collect the secondary fault information of its corresponding device.

[0048] In one embodiment, the robot can reach the designated protection screen cabinet (device to be collected) according to the preset path and action rules, monitor the action of the device to be collected in real time through the visual recognition system or sensor, and record the collected status information and alarm information. The robot can also monitor the status of the alarm indicator light, and determine whether there is an alarm according to the preset rules. If there is an alarm, the alarm type, location and other information are uploaded to the central processor. In another embodiment, the robot can go to the accident-related protection screen, fault recording screen and other secondary cabinet locations according to the preset path and action rules, use a high-definition camera to collect information on the physical status of the pressure plate, circuit breaker, and handle in the on-site protection, and analyze the actual position of the corresponding pressure plate, circuit breaker, and operating handle through the built-in edge computing artificial intelligence recognition algorithm, and then determine whether its position is correct. If not, the error information is uploaded to the central processor so that the central processor can analyze the fault information of the substation.

[0049] Furthermore, the method of the present invention also includes: when receiving a supplementary monitoring instruction, determining a supplementary monitoring robot and a supplementary monitoring device based on the monitoring requirements in the supplementary monitoring instruction; determining second control information of the supplementary monitoring robot based on position information of the supplementary monitoring robot and position information of the supplementary monitoring device; controlling the supplementary monitoring robot to operate based on the second control information, and collecting secondary fault information of the supplementary monitoring device.

[0050] The substation is operated in real time, and there may be new secondary fault information that needs to be collected during the secondary information collection process. Among them, the supplementary monitoring instruction is used to indicate that the substation has generated new secondary fault information that needs to be collected. The monitoring requirements can be understood as the attribute information of the equipment that needs to be supplemented with monitoring, including but not limited to the number, location and name, which is used to determine the supplementary monitoring equipment. The supplementary monitoring robot can be understood as a robot that collects the secondary fault information of the supplementary monitoring equipment. The second control information can be understood as the collection target, operation route, driving speed information and stop information of the supplementary monitoring robot, etc., which is used to instruct the supplementary monitoring robot to collect the secondary fault information of the supplementary monitoring equipment. The advantage of this setting is that comprehensive and highly real-time substation fault data can be obtained, so as to obtain comprehensive, accurate and authoritative substation fault analysis results.

[0051] On the one hand, the present invention also includes an action collaborative communication function, which ensures the synchronization and coordination of actions between multiple robots through precise time synchronization and communication protocols, thereby improving work efficiency and accuracy. On the other hand, it is also possible to plan fault collection actions, that is, to perform path planning and task allocation for multiple robots to ensure that they work together in the working area to avoid conflicts and repeated operations. Safety protection devices will also be considered, such as collision detection, emergency stop buttons, etc., to ensure that the robot operation is stopped in time in an emergency to ensure the safety of personnel and equipment. In addition, the robot of the present invention carries a camera when performing tasks, and the central processing unit can monitor the operating status and working conditions of the robot in real time, and remotely control and adjust it in order to adjust the robot's operating information.

[0052] Optionally, after controlling the information collector to be run to run based on the first control information and collecting secondary fault information of at least one device to be collected, it also includes: when receiving a reset request instruction of the information collector to be run, displaying the operating environment of the information collector to be run; determining whether the information collector to be run meets a preset reset condition based on the operating environment of the information collector to be run; if the information collector to be run meets the preset reset condition, controlling the information collector to be run to perform a reset operation.

[0053] Among them, the reset request instruction of the information collector to be run is used to indicate that there is a reset request for the device corresponding to the information collector to be run. The operating environment of the information collector to be run is displayed to facilitate the staff of the central processor to understand the environmental information of the device applying for reset. The information collector to be run meets the preset reset conditions, which can be understood as the device corresponding to the information collector to be run meets the reset conditions. For example, the central processor has issued a reset consent instruction. The advantage of this setting is to verify the device applying for reset to ensure the accuracy of the reset work.

[0054] In one embodiment, the reset work is performed by a humanoid robot with precise positioning and mechanical arm operation functions. The robot is equipped with a visual recognition system, a force sensor and other equipment for real-time monitoring and precise control of the reset action. The robot monitors the status of the alarm signal indicator light on the protective screen through the visual recognition system, obtains the position information of the alarm signal to be reset in real time, and sends the position information of the alarm signal to be reset to the operator (central processing unit) so that the operator can confirm the position and type of the signal to be reset through the remote monitoring system or on-site observation. After the operator confirms, the robot can accurately locate and use the mechanical arm to press the corresponding reset button according to the confirmed alarm signal position information to perform the reset action. In addition, the robot can also monitor the pressing of the reset button, and feed back the execution results to the central processing system to confirm the execution of the reset action.

[0055] S104: Determine a fault diagnosis result of the substation based on the initial fault information and secondary fault information of at least one device to be collected.

[0056] Among them, the fault diagnosis result can be understood as the fault parameters of the substation, for example, whether the fault range is inside or outside the station, and whether the fault is a permanent fault or a transient fault. Specifically, determining the fault diagnosis result of the substation based on the initial fault information and the secondary fault information of at least one device to be collected can be understood as integrating and integrating the initial fault information and the secondary fault information collected by the information collection robot to determine the fault range, fault type, fault cause, accident development prediction, fault handling suggestions, fault solutions and emergency measures of the substation.

[0057] The advantage of this setting is that it can monitor and analyze the substation operating parameters in real time, propose an optimized scheduling plan based on the diagnosis results, realize intelligent control and scheduling of substation operation, and improve the operating efficiency and stability of the power grid.

[0058] It is worth noting that the present invention will perform data fieldization and standardized storage according to the template preset by the user. On the one hand, it is convenient for operators to call and view, and on the other hand, it is used for substation equipment status assessment. For example, if the related equipment in the same substation fails again in the future, the fault analysis can be combined with the stored historical fault information.

[0059] Optionally, after determining the fault diagnosis result of the substation, it also includes: determining a fault information printing device based on the fault diagnosis result; determining a target fault printing robot based on the location information of the fault information printing device, and controlling the target fault printing robot to perform the fault result printing task of the fault information printing device, wherein the target fault printing robot is an idle fault printing robot closest to the fault information printing device or a fault printing robot corresponding to a device to be collected for which a fault report needs to be printed.

[0060] Among them, the fault information printing device can be understood as a robot that prints fault information. Through the cooperation of the humanoid robot and the robotic arm, the protection screen cabinet door is opened and the touch device panel is clicked to print the protection action report. Specifically, the robot has a built-in portable protection device printer, which can automatically connect to the printing data cable to complete the report printing task. The robot will monitor the report printing situation. After printing, it will close the corresponding protection cabinet door and scan, organize and save the protection report. The advantage of this setting is that the fault report can be printed in time for the debugging personnel to view.

[0061] Figure 2It is a schematic diagram of a secondary information collection system provided by the present invention. The arrows in the figure indicate the direction of information transmission, and the dotted lines indicate the monitoring relationship. It is mainly that the substation secondary information collection robot detects abnormal data of the panel cabinet where the secondary information is located.

[0062] The data analysis model of the present invention is trained and updated regularly. The data analysis model mainly includes data collection and preparation stage, model selection and design stage, model training and tuning stage, model deployment and real-time monitoring stage and continuous improvement and optimization stage.

[0063] The data collection and preparation stage mainly includes: 1) Collecting substation historical data, that is, obtaining substation historical data including equipment operation data, fault data, and alarm information from existing power grid management systems, SCADA systems and other equipment; 2) Data cleaning and preprocessing, that is, performing preprocessing operations such as cleaning, denoising, and outlier processing on the collected data to ensure data quality and availability; 3) Feature engineering, that is, performing feature extraction and feature selection on the processed data to convert the data into feature vectors that can be used for model training.

[0064] The model selection and design stage mainly includes: 1) model selection, that is, selecting a suitable machine learning algorithm or deep learning model, such as decision tree, support vector machine, neural network, etc., according to the nature of the problem and data characteristics; 2) model design, that is, designing the model structure and parameter settings, including network hierarchy, activation function, loss function, etc., to maximize the performance and generalization ability of the model.

[0065] The model training and tuning stage mainly includes: 1) model training, that is, using historical data to train the selected model, and updating the model parameters through the back propagation algorithm and optimizer to minimize the loss function; 2) model evaluation and tuning, that is, using methods such as cross-validation to evaluate and tune the trained model, and adjust hyperparameters to improve the performance and generalization ability of the model.

[0066] The model deployment and real-time monitoring stage mainly includes: 1) model deployment, that is, deploying the trained model to the actual system to process and analyze the substation data in real time; 2) real-time monitoring and feedback, that is, monitoring the performance and effect of the model in actual operation, and adjusting the model based on the monitoring results to ensure the stability and accuracy of the model.

[0067] The continuous improvement and optimization stage mainly includes: 1) data update and retraining, that is, regularly updating the model's training data and retraining the model to adapt to the changes and development of the substation system; 2) model improvement and optimization, that is, improving and optimizing the model according to feedback and needs in actual applications to improve its performance and applicability.

[0068] The technical solution of this embodiment determines the faulty equipment that needs to be monitored again after analyzing the initial fault information of the substation, controls the information collection robot to collect detailed abnormal information of the faulty equipment (equivalent to the secondary fault information), and determines the fault information of the substation based on the initial fault information and the detailed abnormal information of the faulty equipment. The information collection and fault assessment process does not require the participation of power workers, which reduces the consumption of human resources. The automated information collection and data processing method can effectively improve the efficiency, comprehensiveness and accuracy of information collection, thereby improving the accuracy of the fault cause analysis results, reducing the difficulty of fault maintenance work, and speeding up the progress of fault maintenance work. The problem that there are many types of power equipment and the operation is highly professional is solved. If the skill level of power workers is not high, the comprehensiveness and accuracy of the collected secondary fault information are limited, which will affect the fault cause analysis results and fault maintenance work of the substation. If the substation is unattended, the effectiveness of the secondary fault information cannot be guaranteed, which will prolong the progress of the fault cause analysis and maintenance of the substation, and even affect the operation of the substation and social production activities.

[0069] Figure 3 FIG. 1 is a schematic diagram of the structure of a fault information determination device for a substation provided by the present invention.

[0070] The acquisition module 201 is used to determine the secondary information collection task of the substation based on the initial fault information of the substation, wherein the secondary information collection task includes at least one device to be collected.

[0071] Determination module 202 is used to determine the information collector to be operated and the first control information of the information collector to be operated based on the location information of at least one device to be collected, wherein the information collector to be operated includes at least one information collection robot, the first control information includes at least one sub-control information, and the information collection robot corresponds to the sub-control information one by one.

[0072] The control module 203 is used to control the to-be-run information collector to run based on the first control information to collect secondary fault information of at least one to-be-collected device.
