[0002] In modern power systems, control circuits are a key component of circuit breaker operation, and their reliability is directly related to the safe and stable operation of the power grid. The control circuit is responsible for transmitting operating instructions, such as closing and opening commands, and feedback of circuit breaker status information. In addition, the control circuit also cooperates with the protection relay. When an overload, short circuit or other abnormal conditions are detected, the control circuit will instruct the circuit breaker to open to protect the power system.

[0003] In traditional power system design, control loops usually use wired connections to achieve signal transmission and control command execution through a series of relays, contactors and terminals. However, as the scale and complexity of power systems continue to expand, these traditional control loops face some challenges and limitations: traditional control loop designs often have monitoring blind spots, especially at the connection points and transfer switches of the control loops, making it difficult to achieve comprehensive real-time monitoring; when a control loop fails, such as a broken line or poor contact, the location and diagnosis of the fault point are often time-consuming and difficult, affecting the rapid recovery of the power grid.

[0045] In recent years, there have been many accidents of circuit breaker refusal due to control circuit failure. For example, the terminal behind the tripping outlet connector of a 110kV line protection device in the system broke, resulting in line protection refusal; the remote / local switching handle of a 220kV line was rusted, resulting in circuit breaker reclosing failure. It is exposed that the failure of a single component, the lack of detection means, and the lack of evaluation means have caused circuit breaker refusal to occur from time to time, and it is impossible to effectively avoid it. At present, there are monitoring blind spots in the design of circuit breaker control circuits, which often lead to the failure of control circuits or single components to be discovered in time, and they can often be handled after the event, which brings serious hidden dangers to the safe and stable operation of the power grid. Therefore, in order to ensure the safety and reliability of the circuit breaker operation status, it is necessary to open up the circuit breaker monitoring blind spot, achieve real-time monitoring of the circuit breaker operation status, and do pre-processing from post-processing, so as to ensure the safe and stable operation of the power grid.

[0046] In response to the above technical problems, the embodiments of the present application provide a control loop monitoring method, device, electronic device and storage medium, which can timely discover potential faults and abnormalities by real-time monitoring and comparing key parameters of the loop, improve the efficiency and accuracy of fault point location and diagnosis, thereby realizing comprehensive real-time monitoring of the control loop and improving the reliability of the power system.

The terminal may include a mobile phone, a tablet computer or a personal computer (PC).

[0049] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0050] The present application provides a control loop monitoring method, comprising: monitoring a control loop of a circuit breaker in real time through a sensor module to obtain monitoring data; comparing the monitored monitoring data with a preset safety threshold through a signal processing module to obtain a comparison result; when it is determined based on the comparison result that the monitoring data exceeds the preset safety threshold, triggering an alarm module to output a corresponding alarm signal.

[0051] See also Figure 1 , Figure 1 : is a flow chart of a control loop monitoring method provided in an embodiment of the present application. The control loop monitoring method provided in this embodiment can be executed in a control loop of a circuit breaker, and the control loop monitoring method can specifically include the following steps:

[0052] S1. Monitor the control circuit of the circuit breaker in real time through the sensor module to obtain monitoring data;

[0053] Specifically, for step S1, the control loop of the circuit breaker is monitored in real time through the sensor module. The sensor module needs to continuously collect data of the control loop. The parameters monitored in real time by the sensor module may include but are not limited to voltage potential, current potential, temperature, humidity, switch status and other electrical parameters, which are important parameters for the normal operation of the control loop.

[0054] Among them, the sensor module includes multiple small sensor units, which are installed at strategic locations of the circuit breaker control circuit, such as the control circuit entrance, circuit breaker interface, near relays and contactors, at the transfer switch, at the output end of the protection device, key nodes and branch points, and inside the control cabinet.

[0055] S2. The monitored data is compared with the preset safety threshold through the signal processing module to obtain a comparison result;

[0056] Specifically, for step S2, the collected monitoring data needs to be processed by a signal processing module. The signal processing module includes functions such as filtering, amplification, and analog-to-digital conversion to ensure the accuracy and availability of the data. The processed data will be compared with preset safety thresholds. These thresholds are set according to the safe operation standards of the control loop and are used to determine whether the data is within a safe range. The preset safety threshold can also be set based on historical data, statistical analysis, and / or expert knowledge to ensure the safe operation of the control loop.

[0057] S3. When the monitoring data exceeds the preset safety threshold based on the comparison result, the alarm module is triggered to output the corresponding alarm signal;

[0058] Specifically, for step S3, if the monitoring data exceeds the preset safety threshold, the alarm module will be triggered. The alarm module can be in the form of sound and light alarm, SMS notification, system log record, etc., to remind maintenance personnel to pay attention and take corresponding measures. The alarm module includes a sound and light alarm and / or a remote notification system, which is used to provide an immediate alarm when the monitoring data exceeds the safety threshold. The sound and light alarm provides visual and auditory feedback locally. The remote notification system notifies relevant personnel by email, SMS, mobile application push, etc.

[0059] In a specific embodiment, the system can have self-learning capabilities and dynamically adjust safety thresholds according to historical data and environmental changes to adapt to different operating conditions; by collecting a large amount of monitoring data, the system can use machine learning algorithms to predict faults and manage equipment health, discover potential problems in advance, and avoid accidents; the monitoring system can be integrated into a remote monitoring platform, allowing maintenance personnel to view the status of the control loop in real time through the network and perform remote diagnosis. For example, after the central monitoring system receives abnormal data, it performs fault diagnosis and analysis, and sends fault handling suggestions to maintenance personnel based on the fault diagnosis results; the system can integrate multiple types of sensors and improve the accuracy and reliability of monitoring through data fusion technology; users can define specific monitoring rules and alarm conditions according to their needs to make the system more flexible.

[0060] It can be seen that the control loop monitoring method provided in this embodiment can avoid circuit breaker refusal to operate due to control loop failure through real-time monitoring and timely alarm, thereby improving the safety of power grid operation; the system can promptly detect and warn of potential faults, reduce the probability of accidents, and thus improve the reliability of the power grid; through fault prediction and health management, unnecessary maintenance work can be reduced and maintenance costs can be reduced; remote monitoring and diagnosis functions enable maintenance personnel to respond quickly and improve the efficiency of fault handling; through real-time monitoring and timely maintenance, the damage caused by equipment failure can be reduced and the service life of the equipment can be extended.

[0061] Furthermore, in some embodiments, if the monitoring data is the voltage potential of the control loop, the monitored monitoring data is compared with a preset safety threshold by the signal processing module to obtain a comparison result, including:

[0062] The voltage potential is compared with a preset voltage potential safety threshold value through a signal processing module to obtain a comparison result;

[0063] When it is determined based on the comparison result that the monitoring data exceeds the preset safety threshold, the alarm module is triggered to output a corresponding alarm signal, including: when it is determined based on the comparison result that the voltage potential exceeds the preset voltage potential safety threshold, the alarm module is triggered to output a corresponding alarm signal.

[0064] Specifically, if the monitoring data is the voltage potential of the control loop, it is necessary to install the small sensor unit in the sensor module at the entrance of the circuit breaker control loop. The specific steps of the control loop monitoring method are as follows: Use the small sensor unit to monitor the voltage potential of the control loop in real time. The sensor can continuously measure the voltage value and convert it into a processable signal. Compare the monitored potential value with the preset safety threshold. The safety threshold here is the voltage range set to ensure the normal operation of the circuit breaker and its control loop. If the potential value exceeds the safety threshold, the system will trigger the alarm unit to output an alarm signal. The alarm signal can include visual (such as indicator light) and auditory (such as buzzer) indications to prompt operators or maintenance personnel.

[0065] This embodiment improves the accuracy and reliability of potential monitoring through the high-frequency detection circuit and isolation structure of the small sensor unit; the timely alarm mechanism can prevent circuit breaker operation errors caused by voltage abnormalities. Through real-time monitoring and timely detection of problems, the system supports preventive maintenance, thereby reducing unexpected downtime and maintenance costs and enhancing the safety of the power grid; real-time monitoring and rapid alarms help to quickly locate and solve problems and reduce power outages caused by faults; through data analysis and reporting, it can help power companies optimize maintenance strategies and improve maintenance efficiency.

[0066] Furthermore, in some embodiments, if the monitoring data is switch state data of a control loop, the monitored monitoring data is compared with a preset safety threshold by a signal processing module to obtain a comparison result, including:

[0067] The switch state data is compared with a preset switch state value through a signal processing module to obtain a comparison result;

[0068] When it is determined based on the comparison result that the monitoring data exceeds the preset safety threshold, the alarm module is triggered to output a corresponding alarm signal, including: when it is determined based on the comparison result that the switch state of the control loop's conversion switch has changed, the time point when the switch state is sent is recorded, and switch state change information is generated; an alarm signal is generated based on the switch state change information, and the switch state change information is sent to the central monitoring system.

[0069] Specifically, if the monitoring data is the switch status data of the control loop, it is necessary to install a small micro sensor unit at the conversion switch of the control loop. These sensor units are specially designed to monitor the status of the switch. The specific steps of the control loop monitoring method are as follows: Use a small micro sensor unit to monitor the switch status of the control loop, that is, monitor whether the switch is in a closed or open state; when a switch status change is detected, the system will record the time point when the change occurs. This is very important for post-analysis and fault diagnosis; send the switch status change information to the central monitoring system. This allows operators to understand the status of the control loop in real time and take action when necessary.

[0070] In a specific embodiment, by combining historical data and real-time monitoring data, the system can predict possible state changes of the switch and issue an early warning before a potential failure occurs. In addition to monitoring the switch status, the system can also integrate remote control functions, allowing operators to remotely control the closing and opening of the switch. The collected switch status data is deeply analyzed to optimize the control strategy and improve the response speed of the system. The switch status monitoring system is integrated into the smart grid and works in conjunction with other smart grid devices to improve the intelligence level of the entire grid.

[0071] This embodiment ensures that any changes in the control loop can be discovered in a timely manner by monitoring the switch status in real time; enhances the ability of fault diagnosis and post-analysis by recording the time point of the switch status change; improves the reliability and stability of the entire system by monitoring the switch status and sending status information in a timely manner; and improves the control strategy and improves the response speed and efficiency of the system through data analysis and optimization.

[0072] Further, in some embodiments, if the monitoring data is the on-off state data of a relay or a contactor, the monitored monitoring data is compared with a preset safety threshold by a signal processing module to obtain a comparison result, including:

[0073] The on-off state data is compared with the preset on-off state value through the signal processing module to obtain a comparison result;

[0074] When the monitoring data exceeds the preset safety threshold based on the comparison result, the alarm module is triggered to output a corresponding alarm signal, including: when the on / off state of the relay or contactor is determined to be abnormal based on the comparison result, the alarm module is triggered to output a corresponding alarm signal.

[0075] Specifically, if the monitoring data is the on-off status data of relays or contactors, it is necessary to install small micro sensor units near the relays and contactors of the control loop. These sensor units are specially designed to monitor the on-off status of relays and contactors. The specific steps of the control loop monitoring method are as follows: Use small micro sensor units to monitor the on-off status of relays and contactors. These states are critical to the normal operation of the control loop because they directly affect the connectivity of the circuit. When an abnormal on-off state is detected, the alarm unit is triggered to output an alarm signal. This immediate alarm mechanism helps to quickly identify and respond to potential faults. Send abnormal on-off status information to the central monitoring system. Operators can understand the status of the control loop in real time and take action when necessary.

[0076] In a specific embodiment, the system can integrate a self-diagnosis algorithm to automatically analyze the cause of the abnormality and attempt self-healing when possible to reduce human intervention; by analyzing historical data and real-time data of the on and off status, possible failures of the equipment can be predicted, thereby achieving predictive maintenance and reducing unexpected downtime; when an abnormal state is detected, the system can automatically start other related equipment or safety measures, such as disconnecting the power supply or starting the backup system, to protect the safety of the entire system; allowing users to set alarm thresholds according to specific needs, making the system more flexible and adaptable to different application scenarios.

[0077] This embodiment can monitor the on / off status of relays and contactors in real time to ensure that any abnormality in the control loop can be discovered in time; through the instant alarm mechanism, the response speed to abnormal conditions is improved, which helps to reduce the losses caused by failures; by monitoring the on / off status and sending status information in time, the reliability and stability of the entire system are improved; through predictive maintenance, the maintenance strategy can be optimized, unexpected downtime can be reduced, and the efficiency of equipment use can be improved; through intelligent linkage control and user-defined alarm thresholds, the safety and adaptability of the system are enhanced

[0078] Furthermore, in some embodiments, if the monitoring data is the output potential of the monitoring protection device, the monitored monitoring data is compared with a preset safety threshold by the signal processing module to obtain a comparison result, including:

[0079] The signal processing module compares the output potential with a preset output potential safety threshold to generate a comparison result;

[0080] When it is determined based on the comparison result that the monitoring data exceeds the preset safety threshold, the alarm module is triggered to output a corresponding alarm signal, including: when it is determined based on the comparison result that the output potential does not match the preset output potential safety threshold, the control parameters are automatically adjusted, the alarm module is triggered to output a corresponding alarm signal, and the adjusted control parameters are sent to the central monitoring system, and the adjustment operation is recorded.

[0081] Specifically, if the monitoring data is to monitor the output potential of the protection device, it is necessary to install a small micro sensor unit at the output end of the protection device of the control loop. These sensor units are specially designed to monitor the output potential of the protection device. The specific steps of the monitoring method are as follows: Use a small micro sensor unit to monitor the output potential of the protection device. This is to ensure that the protection device can correctly send a signal under abnormal conditions. If the monitored output potential does not match the preset safety threshold, the system will automatically adjust the control parameters. This automatic adjustment function ensures that the system can maintain a safe state under different conditions. Send the adjusted control parameters to the central monitoring system. The operator can understand the adjustment of the system in real time and intervene manually when necessary. The system will record all adjustment operations, which is conducive to subsequent fault analysis and system optimization.

[0082] In a specific embodiment, the system can integrate a machine learning algorithm to learn the optimal control parameter adjustment strategy based on historical data to improve the system's adaptability. Allow operators to view the output potential and control parameters of the protection device in real time through the remote monitoring system and make remote adjustments. The system can consider multiple parameters (such as temperature, humidity, load, etc.) for comprehensive decision-making to achieve more accurate control parameter adjustments. By analyzing the changing trend of the output potential, predict possible problems with the protection device, and perform maintenance in advance to reduce unexpected downtime. Integrate the monitoring system into the smart grid and work in conjunction with other smart devices to improve the intelligence and automation level of the entire power grid.

[0083] This embodiment improves the accuracy of monitoring data by real-time monitoring of the output potential of the protection device; the function of automatically adjusting control parameters enables the system to adapt to different operating conditions and enhances the system's adaptability; by automatically adjusting control parameters, it ensures that the system can still maintain a safe state under abnormal circumstances, thereby improving the reliability of the system; through predictive maintenance, it can optimize maintenance strategies, reduce unexpected downtime, and improve equipment utilization efficiency; through real-time monitoring and automatic adjustment, safety accidents caused by failure of protection devices are reduced, thereby enhancing the safety of the system.

[0084] Further, in some embodiments, if the monitoring data is the current potential of the key nodes and branch points in the control loop, the monitored monitoring data is compared with the preset safety threshold by the signal processing module to obtain a comparison result, including:

[0085] Generate comparison results based on the changing trend of current potential through the signal processing module;

[0086] When it is determined based on the comparison results that the monitoring data exceeds the preset safety threshold, the alarm module is triggered to output a corresponding alarm signal, including: predicting potential fault points based on the comparison results, triggering the alarm module to output a corresponding alarm signal, and sending the potential fault points to the central monitoring system to prompt preventive maintenance.

[0087] Specifically, if the monitoring data is the current potential of the key nodes and branch points in the control loop, it is necessary to install small and micro sensor units at the key nodes and branch points of the control loop. These sensor units are specially designed to monitor the current potential. The specific steps of the control loop monitoring method are as follows: Use small and micro sensor units to monitor the current potential of key nodes and branch points. Monitoring the current potential helps to understand the working status of the circuit and detect current anomalies in time. According to the monitored current potential change trend, the system can analyze and predict potential fault points. This prediction function helps to take measures in advance to prevent faults from occurring. The predicted fault point information is sent to the central monitoring system, and the operator can understand the possible problems in the system in real time and perform maintenance or repairs in advance. The system will prompt for preventive maintenance to reduce unexpected downtime and improve system reliability.

[0088] In a specific embodiment, a machine learning algorithm is used to analyze historical data and real-time data to improve the accuracy of fault prediction; the system can automatically adjust the fault prediction threshold based on the monitoring data to adapt to different working conditions; the fault prediction system is integrated into the intelligent diagnosis platform to work with other monitoring and diagnostic tools to provide a comprehensive system health assessment; operators are allowed to view predicted fault points in real time through a remote monitoring system and provide remote maintenance guidance; and visualization tools such as fault prediction maps are provided to help operators intuitively understand potential problems in the system.

[0089] By predicting potential failure points, this embodiment enables the system to detect problems in advance, thereby improving the foresight of monitoring; predictive maintenance reduces unexpected downtime caused by sudden failures and improves production efficiency; by discovering and solving potential problems in advance, the overall reliability of the system is improved; predictive maintenance helps to allocate maintenance resources more effectively and reduce unnecessary maintenance work; by timely discovering and handling potential failure points, system security is enhanced.

[0090] Further, in some embodiments, if the monitoring data is the temperature and humidity in the control cabinet, small and micro sensor units are installed in the control cabinet, and these sensor units are specially designed to monitor the temperature and humidity in the control cabinet. The specific steps of the control loop monitoring method are as follows: Use small and micro sensor units to monitor the temperature and humidity in the control cabinet. The environmental conditions in the control cabinet are crucial to the normal operation of the equipment. Excessive temperature or humidity may cause equipment failure. If the monitored temperature or humidity exceeds the preset safety range, the system will start the temperature and humidity adjustment system of the control cabinet. This may include starting a fan, air conditioning or dehumidification system. The temperature and humidity adjustment operation information of the control cabinet is sent to the central monitoring system. The operator can understand the environmental status of the control cabinet in real time and intervene manually when necessary. The system will record all adjustment operations, which is very important for subsequent environmental control optimization and fault analysis.

[0091] In a specific embodiment, an intelligent algorithm can be integrated to automatically optimize the temperature and humidity control strategy based on historical data and real-time data to improve energy efficiency and control accuracy. Allow operators to view the environmental conditions of the control cabinet in real time through the remote monitoring system and make remote adjustments. The system can consider multiple environmental parameters (such as temperature, humidity, dust, etc.) for comprehensive control to achieve more comprehensive environmental management. By analyzing the changing trends of environmental conditions, possible environmental adaptability problems of equipment can be predicted, and maintenance can be performed in advance to reduce unexpected downtime. The environmental monitoring system is integrated into the smart grid management system and works in conjunction with other smart devices to improve the intelligence and automation level of the entire power grid.

[0092] This embodiment ensures that any abnormality can be discovered in time by real-time monitoring of the environmental conditions in the control cabinet; reduces equipment failures due to abnormal environmental conditions by automatically adjusting the environment of the control cabinet; improves the reliability and stability of the entire system by monitoring environmental conditions and adjusting them in time; the intelligent environmental control algorithm helps to optimize energy use and reduce energy waste; and reduces safety accidents due to abnormal environmental conditions through real-time monitoring and automatic adjustment.

[0093] Further, in some embodiments, if the monitoring data is the potential of the key nodes and each sub-node in the control loop, it is necessary to install a small micro sensor unit near the key nodes and each sub-node, and the control loop monitoring method includes the following steps: During the monitoring period of the control loop, the potential balance check is performed regularly by the small micro sensor unit. This is to ensure that the potential in the control loop is balanced at each node to avoid failures caused by potential imbalance. The potential of the key node is monitored by the small micro sensor unit and compared with the preset balance standard. If the inspection result shows that the potential is unbalanced, the system will automatically adjust the power supply parameters of the control loop, such as voltage or current, to restore the potential balance. The potential balance check result and adjustment operation information are sent to the central monitoring system. The operator can understand the status of the control loop in real time and intervene manually when necessary. The system will record all potential balance checks and adjustment operations, which is very important for subsequent system optimization and fault analysis.

[0094] In a specific embodiment, the system can automatically optimize the adjustment strategy based on historical data and real-time feedback to restore the potential balance more quickly and effectively. Allow operators to view the potential balance status in real time through the remote monitoring system and make remote adjustments.
