Description

Technical Field

[0001] The present application belongs to the technical field of load flexible regulation, and specifically relates to a remote control method, device and electronic equipment of a flexible regulation unit. Background Art

[0002] The flexible regulation unit is a key component in the intelligent power system, which is used to realize accurate load monitoring of special transformer users and various advanced functions, aiming to improve the flexibility and efficiency of the power system. The flexible regulation unit needs to have the ability to decrypt and analyze remote control instructions, and perform corresponding operations according to the instructions, such as tripping, closing, adjusting output power, etc., while ensuring the safety and accuracy of the operation.

[0003] Since remote control relies on network communication, it is vulnerable to network attacks such as man-in-the-middle attacks (MITM), denial of service attacks (DoS / DDoS), malware infections, etc., which may interfere with the normal transmission of control instructions. Especially in critical areas such as power load management, any security vulnerabilities may lead to major consequences and affect power load control. Summary of the invention

[0004] In order to solve at least one technical problem existing in the background technology, the present application provides a remote control method of a flexible regulation unit, which can greatly improve the safety and effectiveness of remote control in the flexible regulation unit and ensure the stable operation and data security of the power system.

[0009] Monitor the access status of the control circuit, and record and report tripping and closing events;

[0010] Identify the switch input position change and actively report it to the master station system.

[0011] According to the remote control method of the flexible regulating unit provided by the embodiment of the first aspect of the present application, the identity of the request sending end is authenticated before the remote control request arrives, which effectively prevents illegal access and manipulation risks, ensures that only authorized devices or systems can send control instructions, and greatly improves the security protection level of the system. By directly decrypting and generating legal tripping instructions or closing instructions after receiving the remote control request, the intermediate processing links are reduced, the response speed of the control instructions is accelerated, and the switch control of the external load is more accurate and timely, which helps to maintain the stable operation of the system. Real-time monitoring of the access status of the control loop and the automatic recording and reporting of tripping events and closing events provide system maintenance personnel with a detailed operation log, which is convenient for quickly locating problems, timely troubleshooting and maintenance, and reducing downtime caused by unknown faults. By actively reporting the switch input displacement to the master station system, not only the transparency of the system information is improved, but also the master station can grasp the working status of each flexible regulating unit in real time, providing accurate data support for remote centralized monitoring and scheduling decisions, which is conducive to optimizing the resource allocation and scheduling strategy of the overall system.

[0053] like Figure 1 As shown, the first embodiment of the present application provides a remote control method for a flexible adjustment unit, comprising:

[0054] Step 100: Before the remote control request reaches the flexible adjustment unit, the request sender is authenticated.

[0055] In step 100, when the flexible regulating unit is remotely controlled (for example, turning on or off a load), the control command is usually issued by a remote terminal or control system, which can be an operator workstation, an automated dispatching system, a mobile device, or any device authorized to perform such operations. Before the request actually reaches the target flexible regulating unit, the system will require the request sender to prove its identity. This usually involves the following levels:

[0056] Authentication credentials: The sender needs to provide some form of authentication information, such as a username and password, a digital certificate, an access token, or a pre-shared secret key.

[0057] Encrypted communication: In order to protect the security of information during transmission, communication usually adopts encryption technology, such as SSL / TLS protocol, to prevent interception or tampering in the middle.

[0058] Bidirectional authentication: In some scenarios with high security requirements, not only does the request sender need to verify its identity, but the flexible adjustment unit also verifies the legitimacy of the request source, forming a bidirectional authentication to ensure that both ends are trustworthy.

[0059] After receiving the request, the flexible adjustment unit or the security module connected to it will compare the authentication information carried in the request with the authorization information pre-stored in the system. This can be done by database query, public key infrastructure (PKI) verification or other verification algorithms. If the identity authentication is successful, the request will continue to be processed; if it fails, the request will be rejected, and the system will record the attempt and trigger an alarm for further investigation of potential security threats.

[0060] Step 200: After receiving the remote control request, the flexible regulating unit decrypts the remote control request and generates a legal tripping instruction or closing instruction to achieve switch control of the external load.

[0061] In step 200, the flexible adjustment unit first receives authenticated remote control requests, which are usually encrypted to ensure that they are not illegally intercepted and tampered with during network transmission. Then, the flexible adjustment unit uses the corresponding decryption algorithm and key to decrypt the received encrypted control request. The purpose of decryption is to restore the original control instruction information, which is a necessary step to ensure information security and instruction accuracy. After decryption, the system will parse the content of the control request to determine whether it is a valid control instruction. This step includes checking whether the format of the instruction is correct, whether the instruction type (such as tripping or closing) is supported, and whether the target load targeted by the instruction exists. Based on the results of the analysis, the flexible adjustment unit converts the legitimate control requirements into specific internal instructions. For example, if the remote request is to open a certain external load (closing operation), the system will generate a corresponding closing instruction; if it is required to close the load (tripping operation), a tripping instruction is generated. This conversion process ensures that the external control intention can be accurately mapped to the operation that can be executed by the internal control system. The generated legal tripping or closing instructions are then transmitted to the corresponding actuators to realize the actual control of the external load. For example, for the circuit breaker in the power system, the closing instruction will cause the circuit breaker to close and connect the circuit; the tripping instruction will cause the circuit breaker to open and cut off the power supply. Step 200 can ensure that the remote control instructions can be executed safely, accurately and efficiently, while ensuring the safety, reliability and traceability of the system.

[0062] Step 300: monitor the access status of the control loop, and record and report tripping events and closing events.

[0063] In step 300, the working status of the control circuit (such as power line, valve control circuit, etc.) is continuously monitored through sensors, relay status monitoring or communication interfaces, including checking whether the circuit is normally connected, whether there is a short circuit or a circuit break, and whether the equipment is in different states such as standby, operation, and failure. Real-time monitoring helps to quickly identify and respond to any abnormal changes. When a tripping event is detected, that is, the control circuit is disconnected due to the activation of the protection mechanism, the system will automatically record this event. The record content usually includes detailed information such as the tripping time, the tripping reason (such as overload, short circuit, protection action, etc.), and the number of the affected equipment or circuit. These data are essential for analyzing the cause of the fault, optimizing the protection strategy, and preventing future accidents. Corresponding to the tripping event, the system will also record all successful closing operations, that is, the time point when the circuit is re-closed, the operation reason (such as manual reset, automatic reclosing success, etc.) and related equipment information. The closing event record helps to evaluate the system recovery capability and verify the effectiveness of the control logic. Whether it is a tripping or closing event, the system will report this important information to the monitoring center or the upper-level management system. The reporting method can be instant messaging, email, SCADA (supervisory control and data acquisition) system alarm or entered into the database for subsequent query and analysis. Timely information reporting can ensure that management personnel can quickly obtain on-site conditions and make rapid responses, such as dispatching maintenance teams, adjusting operating strategies, etc.

[0064] Step 400: Identify the switch input position change and actively report it to the master station system.

[0065] In step 400, in the control system, the switch quantity usually refers to the binary signal state, that is, "on" or "off", "1" or "0". These signals are often used to indicate the state of the equipment, such as the opening and closing of the circuit breaker, the opening and closing of the valve, the activation and inactivation state of the sensor, etc. The flexible adjustment unit can monitor the changes of these switch inputs in real time through the built-in logic or hardware detection mechanism, that is, the conversion from one state to another, which is the so-called "position change". Once the position change of the switch quantity is detected, the flexible adjustment unit will not wait for the query request of the master station, but will actively (that is, without the request of the master station) report this change information to the master station system through the communication network. This initiative ensures the timeliness of information transmission, so that the master station can immediately understand the changes in the state of the field equipment, which is crucial for rapid response, fault handling, status monitoring and system automation management. The reported information usually includes key details such as the time when the position change occurred, the switch quantity identification involved (such as which circuit breaker, which line), the status before and after the position change, etc. After receiving this information, the master station system can perform further processing based on it, such as updating the system display, triggering an alarm, executing a predefined automated operation process, or providing decision support information for the operator. In summary, the flexible adjustment unit not only enhances the real-time monitoring capability of the system, but also improves the fault response speed, ensures the stable operation and efficiency of the control system, and provides rich data support for the master station, facilitating more efficient management and decision-making.

[0066] According to the remote control method of the flexible regulating unit provided by the embodiment of the first aspect of the present application, the identity of the request sending end is authenticated before the remote control request arrives, which effectively prevents illegal access and manipulation risks, ensures that only authorized devices or systems can send control instructions, and greatly improves the security protection level of the system. By directly decrypting and generating legal tripping instructions or closing instructions after receiving the remote control request, the intermediate processing links are reduced, the response speed of the control instructions is accelerated, and the switch control of the external load is more accurate and timely, which helps to maintain the stable operation of the system. Real-time monitoring of the access status of the control loop and the automatic recording and reporting of tripping events and closing events provide system maintenance personnel with a detailed operation log, which is convenient for quickly locating problems, timely troubleshooting and maintenance, and reducing downtime caused by unknown faults. By actively reporting the switch input displacement to the master station system, not only the transparency of the system information is improved, but also the master station can grasp the working status of each flexible regulating unit in real time, providing accurate data support for remote centralized monitoring and scheduling decisions, which is conducive to optimizing the resource allocation and scheduling strategy of the overall system. In summary, the remote control method of the flexible regulation unit provided in the embodiment of the first aspect of the present application can greatly improve the safety and effectiveness of remote control in the flexible regulation unit, and ensure the stable operation and data security of the power system.

[0067] In some embodiments of the present application, before the remote control request reaches the flexible adjustment unit, the request sender is authenticated, specifically:

[0068] Receive the authentication request initiated by the request sender and verify the legitimacy of the information in the authentication request;

[0069] When the identity verification is successful, a permission check is performed based on the permission level of the request sender;

[0070] Feedback the authentication result to the request sender.

[0071] When the sender of a remote control request attempts to establish contact with the flexible adjustment unit, it first needs to initiate an authentication request. This request contains the sender's identity information, such as an identity identifier, authentication token or password. After receiving this request, the flexible adjustment unit will use a pre-set security algorithm and information in the database to verify the legitimacy of the identity information. This step ensures that the source of the request is known and the information has not been tampered with.

[0072] Once the identity authentication is successful, the system will not immediately execute the control request, but will enter the next security link, namely the permission check. According to the identity information of the sender of the verified request, the system will query its corresponding permission level and operation permission range. For example, some users may only be allowed to view the status, while others have the permission to perform control operations. This step ensures that even if the request comes from a legitimate user, they will only be allowed to perform operations within their authority to prevent unauthorized behavior.

[0073] Finally, the flexible adjustment unit will feedback the result of the identity authentication to the request sender, including whether the verification is successful and, if there is a permission check, the requester will be informed of their permission level and whether they are authorized to perform the requested operation. The feedback mechanism ensures that the requester can understand the status of their request in a timely manner. If the verification fails, it will also be known whether it is due to identity issues or insufficient permissions, so that appropriate measures can be taken.

[0074] Combining the above steps, a secure and reliable remote control environment is built to ensure that only strictly verified and authorized instructions can affect critical infrastructure or equipment, prevent unauthorized access and operation, and provide strong security protection for the system.

[0075] In some embodiments of the present application, after the flexible adjustment unit receives the remote control request, it decrypts the remote control request and generates a legal tripping instruction or closing instruction to achieve switch control of the external load, specifically:

[0076] Conduct safety checks on tripping and closing commands;

[0077] Corresponding to the tripping instruction, a first internal control instruction is generated, and corresponding to the closing instruction, a second internal control instruction is generated, wherein the first internal control instruction will trigger the disconnection of the external load circuit, and the second internal control instruction will trigger the conduction of the external load circuit.

[0078] First, the flexible control unit decrypts the received remote control request, which is a critical step because the request is likely to be encrypted during transmission to protect the command content from being intercepted and tampered with. Decryption uses a pre-agreed security key or algorithm to ensure that only the legitimate recipient can interpret the content of the request.

[0079] After decryption, the system will analyze the type of instruction in the request to determine whether it is required to trip (disconnect the power) or close (connect the power). Based on this judgment, the system will generate the corresponding internal control instruction. This step is to convert the external, more general control signal into an internal instruction that can be directly executed by the device to ensure the accuracy and safety of the control logic.

[0080] Before actually generating the tripping or closing command of the control circuit, the system will perform safety verification on these commands again. This includes but is not limited to the secondary confirmation of the command source, the rationality check of the command logic (for example, avoiding issuing tripping or closing commands at illogical times), and the detection of possible command sequence errors. These verification steps are all to further reduce the risk of misoperation.

[0081] After completing the safety check, the system will generate the first internal control command for the trip command, which is to start the circuit disconnection mechanism to ensure that the power supply of the external load is safely disconnected. For the closing command, the second internal control command is generated, which is responsible for activating the circuit closing mechanism so that the current can flow to the external load and restore power supply.

[0082] From encrypted data transmission to decryption, command legitimacy checking, and precise generation of internal control instructions, each step reflects a high level of attention to security and reliability, ensuring the precise execution of power or other external load control operations while minimizing the risks caused by erroneous or malicious instructions.

[0083] In some embodiments of the present application, the access status of the control loop is monitored, and the tripping event and closing event are recorded and reported, specifically:

[0084] Record and report the timestamp information of tripping and closing events, the source of operation instructions, operation results, and changes in circuit status before and after.

[0085] Timestamp information recording means that every time a trip or close operation occurs, the system automatically records the exact time of the event. Timestamp information is essential for tracking event sequences, troubleshooting, and subsequent analysis. It helps maintenance personnel understand the specific time of the operation and facilitates quick location of problems.

[0086] The source information record of the operation instruction means that the system will record the source of the issued operation instruction, such as manual instructions from the remote control center, instructions from the automated control system, or the triggering of the emergency safety mechanism, etc. This helps to trace the responsibility and evaluate the effectiveness and safety of the instructions. It is also an important basis for audits and compliance checks.

[0087] Operation result information recording means that for each trip or close command, the system will record its execution result, that is, whether the operation is successfully executed. This includes confirming whether the circuit breaker is actually opened or closed, and whether any abnormal situation occurs during the operation. This information is very important for evaluating the accuracy and reliability of the system response.

[0088] Loop status change information recording means that before and after the operation is performed, the system will record the loop status changes in detail, such as the changes in voltage and current, and whether the loop is open or closed. This information not only helps to monitor the operating status of the system in real time, but also facilitates the analysis of the impact scope and potential consequences of the event afterwards, which is of great significance for optimizing control strategies and improving system stability.

[0089] In some embodiments of the present application, the switch input position change is identified and actively reported to the master station system, specifically:

[0090] Analyze the switch input position change and determine whether the position change is "normal operation", "abnormal jump" or "fault jump";

[0091] The identified switch position change information is processed into a data packet and sent to the master station system.

[0092] The flexible adjustment unit will further analyze the nature of the displacement and classify it as "normal operation", "abnormal jump" or "fault jump". This classification is very critical because it directly affects the subsequent processing logic and response measures, including:

[0093] Normal operation means that the change is caused by planned or authorized operations, such as successful execution of remote control instructions.

[0094] Abnormal transitions are those that are not caused by a clear fault but do not fit into the normal operating pattern and may require further investigation.

[0095] Fault transitions are directly associated with system failure or hardware damage and require immediate response to prevent further damage to the system or ensure safety.

[0096] Once the displacement is identified and classified, the flexible control unit organizes the relevant information into standardized data packets. The data packets usually contain the time when the displacement occurred, the nature of the displacement, the identification of the affected equipment or loop, and other necessary metadata. These data packets are then actively uploaded to the master station system through a reliable communication protocol. This active reporting mechanism ensures that the master station can obtain the on-site status in a timely manner and respond quickly, such as adjusting the control strategy, dispatching a maintenance team, or launching an emergency plan.

[0097] In some embodiments of the present application, the method further comprises:

[0098] After executing the trip command or the closing command, the execution control parameters are analyzed, wherein the execution control parameters include response time, execution efficiency, and power consumption;

[0099] Based on the analysis results, adjust the control logic, operation sequence and execution time window.

[0100] After completing the tripping or closing operation, the system does not stop at the successful execution of the operation itself, but further analyzes several key parameters of the entire control process. These parameters include but are not limited to:

[0101] Response time, that is, the time required from receiving a control instruction to actually executing the operation, reflects the response speed of the system.

[0102] Execution efficiency evaluates the resource utilization efficiency during the operation execution process, such as energy utilization efficiency, instruction processing speed, etc.

[0103] Energy consumption. During operations, especially closing operations, the system measures and records the consumed energy, which is related to operating costs and energy efficiency management.

[0104] By analyzing the above parameters, the system can identify efficiency bottlenecks, abnormal responses or abnormal energy consumption during operation, and then take measures to optimize the control strategy. Adjustments involve the following aspects:

[0105] Control logic adjustment: Optimize the control algorithm, such as dynamically adjusting the control strategy through machine learning algorithms to make it more adaptable to the current operating environment and load changes.

[0106] Adjust the operation sequence: Rearrange the operation sequence to ensure that the logic between operations is more reasonable, reduce unnecessary waiting time, and improve overall execution efficiency.

[0107] Execution time window adjustment: Adjust the optimal execution time of control operations based on analysis results, such as avoiding peak power consumption periods to perform certain operations to reduce the impact on system stability and energy consumption.

[0108] This closed-loop control optimization mechanism, through continuous self-analysis and adjustment, not only ensures the efficient execution of each operation, but also promotes the continuous improvement of long-term operating efficiency and energy efficiency. It realizes dynamic optimization of control strategies through real-time data feedback and intelligent analysis, ensuring that the power system or industrial automation equipment operates in the best state.

[0109] In some embodiments of the present application, the method further comprises:

[0110] Receive updated configuration parameters of the master station system and perform configuration updates;

[0111] Among them, the updated configuration parameters include control logic, security policy and operation threshold.

[0112] The flexible regulation unit can remotely receive configuration update instructions from the master system, which means that even if the regulation unit is located in a remote or difficult to directly access location, its internal settings can be adjusted and optimized through the network. This greatly improves the system's maintainability and ability to respond to changes in external conditions.

[0113] The update of control logic involves adjusting the operation strategy, optimizing the algorithm or adding new control rules to cope with new demands in system operation or improve the existing control effect. For example, the load balancing algorithm can be improved based on historical data analysis to allocate power resources more efficiently.

[0114] The update of security policies ensures that the system can cope with the latest security threats. This includes strengthening authentication mechanisms, updating encryption algorithms, adjusting access control lists, etc. to strengthen system defense and prevent unauthorized access and operation.

[0115] The adjustment of the operating threshold is based on the system operating conditions and performance optimization requirements, such as adjusting the voltage and current thresholds for tripping or closing to more accurately control equipment operation, prevent overload or improve efficiency. This helps prevent potential failures and optimize system operation economy.

[0116] After receiving the update instruction, the flexible adjustment unit will verify the integrity of the data and the legitimacy of the source to ensure the security of the updated content. After the verification is passed, the internal configuration will be modified or replaced accordingly according to the instruction, so that the adjustment unit can operate according to the latest control logic, security policy and operation threshold.

[0117] In this way, the flexible adjustment unit can dynamically adapt to changes in system demand and maintain optimal working conditions, while ensuring the safety and stability of the system. Remote configuration update capability is one of the core elements for efficient management and maintenance of complex systems such as smart grids and industrial automation.

[0118] In some embodiments of the present application, receiving updated configuration parameters of the master station system and performing configuration update are specifically:

[0119] Back up the current original configuration parameters;

[0120] Perform security verification and integrity verification on the received update configuration parameters;

[0121] After verification, regional or modular updates are carried out.

[0122] Before starting any update, the system first performs a comprehensive backup of the configuration parameters currently in use. This is an important precautionary measure. In case of unexpected events during the update process or problems caused by the new configuration, you can quickly roll back to the previous stable state to ensure that the system continues to run unaffected.

[0123] The system will perform security checks on the update packages received, including verifying the legitimacy of the source (ensuring that the data comes from a trusted master system) and checking whether the data package has been tampered with or contains malicious code, in order to prevent potential network security threats. Through checksums or other integrity checks, it is confirmed that the update package has not been damaged or key parts are missing during transmission, ensuring that the update content is complete and correct.

[0124] After verification, regional or modular updates are carried out. Specifically,

[0125] Regionalized update means that, based on the system structure and control logic, the update is designed to be performed by region or subsystem, which can minimize the impact of the update on the entire system and ensure that other non-updated parts continue to operate normally.
