Description

Technical Field

[0001] The present invention relates to the technical field of power safety, and particularly relates to a comprehensive intelligent anti-misoperation system and an anti-misoperation method thereof. Background Art

[0002] Substations (step-up substations) are important components of the power system, responsible for tasks such as voltage level conversion, load connection and disconnection. Their reliable and stable operation directly relates to the safety of the power grid, equipment and personnel. The anti-misoperation system is the key to preventing operation errors and accidents of operation and maintenance personnel. The technical measures for preventing misoperation mainly involve using mechanical structures and electrical principles to forcibly lock the operating mechanisms of equipment, that is, the five-prevention locking technology.

[0003] To build a new power system, a large number of new energy sources need to be connected to the power grid, and a large number of power electronic devices need to be put into use. With the popularization and application of substation automation technology, it is just around the corner to realize the intelligence and wisdom of primary equipment. The application of intelligent components provides a solution for the intelligence of primary equipment. Primary equipment gradually develops into intelligent primary equipment by installing and integrating intelligent components. As a form of intelligent components, the comprehensive intelligent anti-misoperation operating system realizes the intelligent features of digital measurement, networked monitoring, visual status, online logical discrimination, integrated functions, information interaction, and automated operation execution (programmed operation) of each component of the five-prevention system; the comprehensive intelligent anti-misoperation operating system realizes the anti-misoperation locking function for the whole station and the whole network through anti-misoperation locking software, simplifies the interface between the automation system and primary equipment, reduces auxiliary contacts and wiring, and improves the reliability of the automation system. It is the development need of the intelligent (digital) power grid and an important part of future intelligent substations. Summary of the Invention

[0004] In order to solve the above technical problems in the present application, the present invention provides a comprehensive intelligent anti-misoperation system.

[0005] The present invention provides the following technical solution: A comprehensive intelligent anti-misoperation system includes an anti-misoperation module, an intelligent access control module, an intelligent lock control module, a video module, and an intelligent wearable module;

[0006] The anti-misoperation module comprehensively displays information related to the power system on the system platform and sets up a complete anti-misoperation logic for the operator to perform operations;

[0007] The intelligent access control module can record information about the substation gate and equipment area gates;

[0008] The intelligent lock control module is used for the safety control of equipment gates such as access doors, secondary screen cabinet doors, terminal boxes, and mechanism boxes. The intelligent lock control module mainly consists of intelligent locks and intelligent keys;

[0009] The video module uploads all the information of the substation to the system platform completely, and uses artificial intelligence algorithms for associated information, taking the algorithm results as the basis for the auxiliary logic discrimination of the anti-misoperation module;

[0010] The intelligent wearable module manages all intelligent wearable devices, and displays the physical information of the staff in the area where they are located in real time to ensure the safe operation of the staff.

[0011] The anti-misoperation method of the intelligent anti-misoperation system specifically includes the following steps:

[0012] S1. The measuring and control device collects the status information of primary and secondary equipment, uploads it to the integrated main and auxiliary monitoring host, and uploads it to the centralized control station monitoring system through the real-time network gateway. The integrated main and auxiliary monitoring host will upload the information to the comprehensive intelligent anti-misoperation host and request verification. After the comprehensive anti-misoperation host completes the verification, it issues the verification result and the remote control command;

[0013] S2. The dispatcher can directly issue operation instructions through the remote control machine to achieve equipment operation;

[0014] S3. The comprehensive intelligent anti-misoperation host issues tasks to the intelligent grounding wire cabinet, and the intelligent grounding wire cabinet feeds back the status information in real time;

[0015] S4. The comprehensive intelligent anti-misoperation host issues commands to the security edge proxy device. The security edge proxy device issues instructions to the intelligent helmet to pick up the intelligent helmet, records and stores the operation records and uploads them. The security edge proxy device issues instructions to the intelligent access control to control the entry and exit of the staff. The security edge proxy device issues instructions to the four-free camera to record and upload the status and position information of the on-site equipment in real time. The security edge proxy device issues instructions to the aggregation node, and then transmits the operation instructions to the intelligent anti-misoperation terminal and the intelligent key wirelessly for subsequent unlocking operations;

[0016] S5. After all operations are completed, the equipment status information and operation records are reported in real time, and finally uploaded to the centralized control station monitoring system for record keeping.

[0017] When carrying out routine maintenance and inspection work, the maintenance personnel create a work task, determine the work scope and work content. The task can be selected and saved as a typical task for direct pulling next time for convenient operation. After the task is created, it is issued to the intelligent key through the platform. The maintenance personnel can get the intelligent key and go to the site for unlocking operations to enter the inspection area for routine inspection work. When unlocking with the key, single-step anti-misoperation verification will be carried out. If the verification passes, the unlocking is successful, and the maintenance personnel can carry out subsequent work normally. If the verification fails, the intelligent key will feedback the reason.

[0018] When the actual switching operation is changed from remote to local operation, the operation and maintenance personnel create a local operation task on the platform, determine the working scope and content. During the task creation process, the platform will automatically perform topology verification according to the anti-misoperation rules. The task can be successfully created only after meeting the rules, otherwise it will return for review. After the task creation is completed, a simulation preview is carried out on the computer side. After passing the anti-misoperation verification, area authorization is performed and an operation task is generated. If it fails, an alarm prompt is issued. If the preview passes, directly go to the site for local operation, or go to the next step to send the operation task to the intelligent key. The operation and maintenance personnel hold the intelligent key and enter the work site to perform the unlocking operation. When using the key to unlock, single-step anti-misoperation verification will be carried out. If the verification passes, the unlocking is successful and the operation and maintenance personnel can carry out the subsequent work normally. If the verification fails, the intelligent key will feedback the reason.

[0019] The request verification of the integrated intelligent anti-misoperation host includes the following steps:

[0020] F1: During normal switching operations, the measuring and control device updates the verification and locking contact information in real time. The monitoring system controls the anti-misoperation locking contacts through the measuring and control device, and the integrated intelligent anti-misoperation system controls the Internet of Things anti-misoperation contacts. The two groups of contacts complete the action to form a complete control loop to control the device action.

[0021] F2. If the monitoring system fails and exits the operation, the integrated intelligent anti-misoperation system controls the action of the Internet of Things anti-misoperation contacts, the circuit is closed, and the device action is controlled, still ensuring the safety of the switching operation and preventing misoperations.

[0022] F3. If the integrated intelligent anti-misoperation system fails and exits the operation, the monitoring system controls the locking contacts through the measuring and control device, the control circuit is closed, and the device action is controlled, and the switching operation is safe and controllable.

[0023] The present invention relates to a comprehensive intelligent anti-misoperation system, and its beneficial effects are as follows: 1. Online real-time judgment is carried out to achieve a complete anti-misoperation function. The anti-misoperation host can monitor the execution progress of the operation ticket in real time, and monitor the operation conditions of primary equipment, secondary equipment, and auxiliary equipment in real time. Once an operation that violates the anti-misoperation rules occurs, the anti-misoperation system can forcibly lock the operation of the equipment and send an alarm message. After this step of operation is completed, the next step of operation is released only when the corresponding equipment status change is detected, fundamentally eliminating the "empty stroke"; 2. A multi-level anti-misoperation network including the station control layer, between stations, and the power grid is formed to improve the reliability of the system. Multi-level anti-misoperation of the power grid, between stations, the station control layer, the bay layer, and the process layer can be comprehensively achieved, and multi-level anti-misoperation works complementarily at the same time. For example, when the anti-misoperation of the station control layer fails, the anti-misoperation of the bay layer can still achieve the anti-misoperation of the whole station; 3. Online anti-misoperation special locks are adopted to sense the equipment and lock status in real time, realizing online monitoring of manual operation equipment such as temporary ground piles, disconnectors, and grid doors, avoiding monitoring dead corners, and comprehensively improving the anti-misoperation technical performance and reliability; 4. Support multi-task parallel operation, increasing the flexibility of operation. The real-time performance of the background monitoring system and the intelligence of the anti-misoperation software are organically integrated, supporting reliable multi-task concurrent execution, and the associated operations are checked against each other in real time, increasing the flexibility of operation; 5. Intelligent automatic locking logic editing and simplified operation steps shorten the operation time. The computer key can be omitted, and there is no need to check the corresponding status of the computer key, avoiding multiple round trips between the main control room and the switchyard, reducing the operation burden, improving the operation efficiency, shortening the operation time, and especially providing a simple technical guarantee for single-person operation.

[0032] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in combination with embodiments and drawings to fully understand the purpose, scheme and effects of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. It should be noted that unless otherwise specified, when a certain feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. In addition, the up, down, left, right, etc. descriptions used in the present invention are only relative to the mutual positional relationship of the components of the present invention in the drawings.

[0033] As Figure 1 shown, the present invention discloses a comprehensive intelligent anti-error system, belonging to the field of power Internet of Things security technology, including an anti-error module, an intelligent access control module, an intelligent lock control module, a video module, and an intelligent wearable module.

[0034] The anti-error module comprehensively displays relevant information of the power system on the system platform, including specific information such as the opening and closing, voltage, temperature, etc. of primary equipment such as circuit breakers, disconnectors, earthing switches, etc. The anti-error system sets up a complete anti-error logic for the operator to operate;

[0035] The intelligent access control module can input information about the substation gate and equipment area gates. When staff want to enter the substation or related areas, they need to be authorized by the access control and can enter through password, card swiping, or face recognition;

[0036] The intelligent lock control module is used for the safety control of equipment doors such as access doors, secondary screen cabinet doors, terminal boxes, and mechanism boxes. The intelligent lock control template is mainly composed of intelligent locks and intelligent keys. The intelligent access control module and the intelligent lock control module can be used as auxiliary systems of the anti-error module to control access doors, operating mechanisms of primary equipment, secondary equipment screen cabinet doors, etc., and the three are used together to effectively ensure the safe operation of power grid equipment and personal safety;

[0037] The video module uses a brand-new fully intelligent four-free camera, which can upload all the information of the substation to the system platform under the conditions of no light, no power, no network, and no on-site operation and maintenance, and uses artificial intelligence algorithms for associated information, and uses the algorithm results as the basis for the auxiliary logic discrimination of the anti-error module;

[0038] The intelligent wearable module controls all intelligent wearable devices. When staff enter the station for work, they wear devices such as intelligent helmets, intelligent bracelets, and intelligent glasses. The module can display the physical information of the staff in the current area in real time, such as heart rate, blood pressure, steps, etc., detect the health status of the staff, and ensure the safe operation of the staff. The intelligent wearable devices interact with the integrated intelligent anti-error system, track the location of the operators online, and through feedback mechanisms such as voice or vibration, remind the operators of entering the live area by mistake, operating errors, dangers and potential hazards, etc. The intelligent wearable devices can record the operation logs through audio and video and upload them, and verbally inform the operators of the work content.

[0039] Figure 2 It is a structure diagram of an integrated intelligent anti-error system. The application layer and the platform layer are composed of the integrated intelligent anti-error system and the data server; the network layer exchanges data through the network gateway and the switch; the station control layer collects the information uploaded by the bay layer and the device layer; the bay layer is used to connect electrical equipment and various terminals; the device layer mainly includes various locks, wearable devices, identification devices, etc. The application layer is equipped with the integrated intelligent anti-error system and the Internet of Things anti-error system. The platform layer is responsible for big data and cloud computing. The network layer conducts communication and data transmission. The perception layer is configured with intelligent anti-error terminals, intelligent locks, face recognition devices, intelligent helmets, and intelligent wearable devices. The instructions are issued through the application layer, calculated and verified by the platform layer, transmitted by the network layer, and received and executed by the perception layer. The station control layer, the bay layer, and the device layer perform switching operations. The operator selects the module to be operated in the application layer and issues an operation instruction. After topological calculation and verification, the network layer receives the operation instruction and transmits it to the corresponding equipment in the substation. After the equipment receives the instruction, various intelligent terminals are authorized, and the operator can perform the unlocking operation. After the operation is completed, the intelligent terminal collects and uploads the equipment status information, and through the network layer, the information is sent to the application layer, and the management personnel can view the real-time status information of the equipment in the application layer. The relevant instructions of the system are issued through the application layer, calculated by the platform layer, and transmitted by the network layer, and received by the perception layer. The station control layer and the bay layer cooperate with the device layer for operation. It realizes the safe control of substation equipment. At the same time, the terminal equipment can upload the information after the operation to the application layer and the platform layer, and the real-time status of the equipment after the operation is displayed on the application layer, and the management and operators are informed. The multi-level anti-error operation network improves the reliability of the system. It can comprehensively achieve multi-level anti-error operations for the power grid, between substations, the station control layer, the bay layer, and the device layer. The multi-level anti-error works simultaneously. For example, when the anti-error of the station control layer fails, the anti-error of the bay layer can still achieve anti-error for the whole station and the whole power grid.

[0040] Figure 3It is a schematic diagram of a comprehensive intelligent anti-misoperation system. In the security zone I, at the station control layer, there are one-key sequence control hosts, main and auxiliary integrated monitoring hosts, remote terminal units, and real-time network gateways. At the bay layer, there are measurement and control devices, which execute switch operation commands and detect the terminal devices in the process layer in real time, collect the data information of the terminal devices and execute upload. At the security zone II, at the station control layer, there are service network gateways, integrated application servers, and comprehensive intelligent anti-misoperation hosts. At the security zone IV, at the station control layer, there are security edge proxy devices and four-free video servers. At the bay layer, there are access nodes and aggregation nodes. At the device layer, there are terminal devices (four-free cameras, intelligent locks, face recognition devices, intelligent helmets). The operation instructions are sent from the comprehensive intelligent anti-misoperation host, monitoring host, and remote terminal unit to the intelligent terminals, passing through the station control layer, bay layer, and device layer. Through the measurement and control devices, access nodes, and aggregation nodes at the bay layer, the instructions are sent to the terminal devices to execute corresponding operations. The lock and device information in the process layer is uploaded in real time through the bay layer, and the platform layer updates the device information in real time and records and saves it.

[0041] Figure 4 It is a schematic diagram of a comprehensive intelligent anti-misoperation interlocking loop. During normal switch operations, the measurement and control devices update and verify the interlocking contact information in real time. The monitoring system controls the anti-misoperation contacts through the measurement and control devices, and the comprehensive intelligent anti-misoperation system controls the Internet of Things anti-misoperation contacts. The two groups of contacts complete the actions to form a complete control loop to control the device actions. If the monitoring system fails and exits operation, the comprehensive intelligent anti-misoperation system controls the Internet of Things anti-misoperation contacts to act, the loop closes, and the device actions are controlled, still ensuring the safety of switch operations and preventing misoperations. If the comprehensive intelligent anti-misoperation system fails and exits operation, the monitoring system controls the interlocking contacts through the measurement and control devices, the control loop closes, and the device actions are controlled, making the switch operations safe and controllable. Online real-time anti-misoperation logic judgment is carried out to achieve a complete anti-misoperation function. The anti-misoperation host and the simulation terminal perform simulation previews and monitor the execution progress of the operation ticket in real time, and monitor the personnel operations and the actions of primary equipment in real time. Once an operation violating the anti-misoperation rules occurs, the anti-misoperation system forcibly locks the operations of the corresponding devices and issues warning information. After this step of operation is completed, it is detected that the monitoring device has completed the corresponding actions and the device status has changed before releasing the next operation, fundamentally eliminating the "idle run". The anti-misoperation interlocking logic is intelligent and can be automatically generated, and at the same time, it is automatically checked against the anti-misoperation module locking logic of the monitoring system. The anti-misoperation logic is based on rapid topology analysis and established on the basis of "electrical principle" + "management rules". Under various wiring methods and various operating modes, the system can automatically and accurately identify misoperation behaviors violating the electrical principle and lock them. Anti-misoperation judgment is carried out based on the information of the entire power grid (or centralized control station), realizing the intelligence of anti-misoperation logic within the entire network, meeting the requirements of inter-station interlocking, and realizing risk prompts such as N-1 and N-2 for switch operations in the power grid and electromagnetic loop network risk prompts. It has the function of multi-site collaborative operation, which can effectively avoid misoperation accidents caused by inconsistent coordination of operation progress in different substations.

[0042] Figure 5 It is a data flow diagram of a comprehensive intelligent anti-error system. The measurement and control device collects the status information of primary and secondary equipment, uploads it to the main and auxiliary integrated monitoring host, and uploads it to the centralized control station monitoring system through the real-time network gateway. The main and auxiliary integrated monitoring host will upload the information to the comprehensive intelligent anti-error host and request verification. After the comprehensive anti-error host completes the verification, it will issue the verification result and remote control command. The dispatcher can directly issue operation commands through the remote terminal unit to achieve equipment operation. The comprehensive intelligent anti-error host issues tasks to the intelligent grounding wire cabinet, and the intelligent grounding wire cabinet real-time feedbacks the status information. The comprehensive intelligent anti-error host issues commands to the security (anti-error) edge agent. The security edge agent device issues commands to the intelligent helmet, retrieves the intelligent helmet, records and stores the operation records and uploads them. The security edge agent device issues commands to the intelligent access control to control the entry and exit of staff. The security edge agent device issues commands to the four-free camera to capture and record the status of on-site equipment and the location information of personnel in real-time and upload them. The security edge agent device issues commands to the aggregation node, and then transmits the operation commands to the intelligent anti-error terminal and intelligent key wirelessly for subsequent unlocking operations. After all operations are completed, the equipment status information and operation records are reported in real-time and finally uploaded to the centralized control station monitoring system for record storage. The centralized control station monitoring system, the main and auxiliary integrated monitoring system, the comprehensive intelligent anti-error host, the anti-error edge agent, and the intelligent key can all create tasks and issue operation commands. This system is a substation anti-error system that adopts an intelligent anti-error judgment model of "electrical principle + management rules" and power grid fast topology analysis technology. It can obtain the status information of equipment, locks, grounding wires, primary equipment compartment doors, etc. in real-time, support the anti-error verification of item-by-item operations and sequence control operations, achieve anti-error for remote and local operations, physical protection of secondary equipment and network equipment, and anti-error functions for maintenance and operation and maintenance work

When carrying out operation and maintenance inspection work daily, in accordance with the operation and maintenance work process of the comprehensive intelligent anti-error system, the on-site staff are informed of the operation scope and operation process. The operation and maintenance personnel create a work task, determine the work scope and work content. The task can be saved as a typical task for direct pulling next time for convenient operation. After the task is created, it is issued to the intelligent key through the platform.

If the verification passes, the unlocking is successful, and the operation and maintenance personnel can carry out subsequent work normally. If the verification fails, the intelligent key will feedback the reason. After the work is completed, the intelligent key is returned, and the operation record is automatically uploaded to the platform for record storage

The operation and maintenance personnel create an on-site operation task in the interface of the comprehensive intelligent anti-misoperation system, determine the working scope and content. During the task creation process, automatic topological verification will be carried out according to the anti-misoperation rules. It can be successfully created only after meeting the rules, otherwise it will return for review. After the task creation is completed, a simulation rehearsal is carried out on the computer side. After passing the anti-misoperation verification, area authorization is carried out and an operation task is generated. If it fails, an alarm prompt will be issued. If the rehearsal passes, it will go to the next step, generate an operation task and send it to the measurement and control device and the edge security edge proxy device. The device receives the correct operation task after simulation, interacts with the comprehensive intelligent anti-misoperation host in real time during the on-site operation process, performs single-step anti-misoperation verification online, and transmits the device and lock status in real time to complete the switching operation.
