Description

Technical Field

[0001] The present invention relates to the technical field of power information management, and in particular to a power information centralized control error prevention device and method. Background Art

[0002] The search formula is TACD_ALL:(server AND equipment AND management AND station monitoring AND five defenses), and the relatively close existing technical solutions are as follows.

[0003] The authorization announcement, CN 105373024 B, is titled "A Remote Control Error Prevention Mechanism for a Substation Monitoring System." This mechanism effectively improves the reliability of the remote control link in the substation system while enhancing the security of the remote control process. This error prevention mechanism comprises a table check mechanism and a remote control token mechanism, ensuring the correctness of remote control actions from both the inspection and execution perspectives. Implementation of this mechanism does not require any modifications to the protocol or system architecture, ensuring remote control security without compromising system security.

[0004] The application publication number is CN 111934429 A, and its name is "Method for Sequential Control of the Master Station Calling the Station End." Based on the configuration of a one-button sequential control function on the station end, this method upgrades and transforms the basic platform of the dispatching control system and deploys the calling function, constructing an operating architecture in which the master station calls the station end operation sequence, and the station end backend is responsible for execution and feedback. The present invention interconnects multiple technical links of the dispatching master station and the station end system, achieving joint control and integrated operation of the two major professional fields of dispatching and operation and inspection, further clarifying the boundaries of safety responsibilities between different systems, and significantly improving the efficiency and intelligence level of power grid switching operations.

[0005] The application publication number is CN 112698127 A, and its name is "Online Monitoring System for Substation Anti-Error Locking Equipment Based on a Networked Five-Prevention System." The management and control platform includes a provincial company management and control platform, a prefectural company operation and maintenance center, and a substation or switchgear workstation. Based on the network architecture of the five-prevention system, each station's anti-error system communicates with the network anti-error master station system at the operation and maintenance center. The system utilizes the internet, smart chips, and IoT technologies to automatically identify and connect anti-error equipment, as well as comprehensive status perception of core components, enabling real-time monitoring of operating conditions, statistical analysis of operations, and ledger statistics. Information is uploaded and distributed using unified protocols, enabling intelligent integration and related application of business logic, as well as the capture and intelligent analysis of big data. The system builds a new generation of intelligent anti-error locking integrated management and control system that integrates operation-based centralized control and anti-error, safety-based online monitoring of operating conditions, and full-life asset management, achieving highly intelligent, information-based, and platform-based substation operation and maintenance, as well as safety management.

[0048] Technical solution description:

[0049] With the development and application of microcomputer-based anti-error locking technology in power systems, microcomputer-based anti-error locking devices have become a crucial technical tool for ensuring safe operation of power systems. In recent years, power systems have been promoting unmanned or understaffed substation operation. In unmanned substations, disconnectors and earthing switches are often operated by a team of operators stationed in a centralized control center. These teams are responsible for operating disconnectors and earthing switches at multiple stations. Due to the diverse electrical wiring and equipment at each substation, operators face a wide variety of equipment, a large volume of equipment, and a lack of familiarity with the actual operating status of on-site equipment, making operation errors more likely. This is why centralized microcomputer-based anti-error locking systems have emerged.

[0050] The centralized microcomputer-based anti-error locking system operates in a client / server configuration, achieving centralized and unified control through a local area network interface. The centralized control terminal can view the equipment status of all stations and perform operations across all stations; the station control terminal can view and operate equipment status at the current station. The client and server share information and data via a high-speed broadband network. The entire system utilizes the latest network communication and computer software technologies, is based on network communication and data collaboration, and is guaranteed by secure and reliable system management. It features flexible operation, comprehensive anti-error features, and a rich and practical network management system for operation tickets. It is one of the best solutions for addressing anti-error issues in centralized control stations.

[0051] Design goals:

[0052] This system is based on local area networking and establishes a microcomputer anti-error locking system information operation platform that uses network connection, unified overall five-prevention operation and operation ticket network management.

[0053] The overall goals achieved by this system are as follows:

[0054] Establish a centralized control center as the core, connect all subordinate substations to realize data interaction function, and the station-side operation ticket is uniformly authorized by the centralized control and error prevention system. After the operation is completed, the centralized control and error prevention system will uniformly archive it to the PMS system.

[0055] The centralized control and error prevention system interfaces with the PMS system to enable unified data interaction between the centralized control and error prevention system and the PMS (task review, process flow, and task archiving) for the operation tickets of each substation under its jurisdiction.

[0056] The centralized control and error prevention system interfaces with the new generation centralized monitoring system to achieve unified data exchange between the centralized control and error prevention system and the new generation centralized monitoring system (error prevention verification for operation tickets).

[0057] The centralized control error prevention system must have the sequential control error prevention function, and the sequential control error prevention interface with the monitoring system to realize the "double verification" function of the error prevention logic to ensure that the remote control and sequential control operations of the centralized control station are correct and reliable.

[0058] System Architecture:

[0059] like Figure 1 As shown in the figure, this solution primarily consists of a centralized control and error prevention server, a centralized control and error prevention workstation, a centralized control sequence function module, a forward / reverse isolation device, and a station-side five-protection system. The centralized control and error prevention server is the error prevention server, the centralized control and error prevention workstation is the error prevention workstation, the isolation devices include forward and reverse isolation devices, the PMS runs on the device management server (PMS), the centralized monitoring server is the next-generation centralized monitoring system, the station-side monitoring server runs on the station-side monitoring system, and the station-side five-protection server runs on the station-side five-protection system.

[0060] Centralized Control Center Hardware Configuration: One error prevention server is deployed in the control center. The server interfaces with the next-generation centralized monitoring system and the PMS system to enable corresponding business data exchange functions (PMS process flow, error prevention verification of operation tickets, and "double verification" of sequential control). One error prevention workstation is deployed in the control center to implement routine operation ticket operations. One switch, one forward isolation device, and one reverse isolation device are deployed in the control center to meet the network security requirements for data exchange between Zones I and III.

[0061] Substation configuration:

[0062] Upgrade the software version of the station-side error prevention system to realize the unified operation ticket process flow of the centralized control error prevention system when the sub-station task is initiated.

[0063] Software Configuration:

[0064] It uses the latest power safety management system software and has passed the information security level 3 inspection of the State Grid Nanjing Electric Power Research Institute; it supports operation on Linux, Unix, and Windows operating systems; it supports diagram and model sharing and listing maintenance locking, and includes functions such as operation ticket library, data management, communication management, system management, and window management; the stand-alone version and the control / centralized control version have unified operating styles and interfaces; line names and equipment numbers can be renamed with one click, making data maintenance simpler; computer key initialization function can be completed with one click, making after-sales service easier; primary diagram wiring diagrams can be quickly drawn; basic plant and station anti-error data can be automatically generated; the system has excellent stability and supports 7*24 hours of uninterrupted operation.

[0065] Graphic operation ticket expert system module: It realizes functions such as software error prevention, simulation preview, data editing, printing and editing of operation tickets, and is the core part of the entire error prevention system. The system provides multiple invoicing methods such as graphic invoicing, transfer order invoicing, calling typical operation tickets, calling pre-order tickets, calling historical tickets, etc. to meet different needs. Simulation operations of primary and secondary equipment can be performed on the screen, supporting automatic simulation and manual simulation. It can automatically judge the correctness of the operation according to the five-prevention principles and operating methods, and issue intelligent voice warnings for incorrect operations. It includes equipment alignment function, which intuitively reflects the working status of the system through the simulation components on the primary system diagram of the graphic system, and automatically refreshes without manual alignment. After entering the graphic system, you can draw graphics or import existing graphics in the graphic model editing interface. And you can directly set the corresponding properties in the graphic system. There is no need to call external software, and the system supports independent operation.

[0066] Operational Data Management System Module: This module includes basic data, plant and station data, equipment linkage, diagram editing, statistical data, and log management. It allows operators to expand and modify relevant databases and files based on changes in the application environment. For example, changes to the primary system, protection mode, or operating mode may require modifications to locking rules or equipment dual-number names. It also provides statistical management of on-site equipment, locks, and ground wires. It records historical operation information, including system logs, alignment logs, and black box records. This information includes user login time, alignment status, invoicing information, and operational status, making it easy to query and providing a basis for scientific operation management.

[0067] like Figure 2 The following is a description of the system interface.

[0068] Cybersecurity Implementation:

[0069] While meeting information security requirements and integrating the substation's existing channels and network communication equipment, a network channel was added between the centralized control and error prevention server and the next-generation centralized monitoring system to enable two-way data transmission. A forward / reverse isolation device was deployed in the centralized control center to achieve cross-zone connectivity between Safety Zones I and III. Leveraging existing network equipment within the substation, a network channel was added between the station-side error prevention system and the centralized control and error prevention server to enable two-way data transmission.

[0070] System principle:

[0071] The system adopts C / S (client / server) software architecture design. The five-defense server acts as the server to uniformly manage the data of each controlled substation, ensuring effective review and supervision of each controlled station; the five-defense system of the controlled substation acts as the client to obtain the operation mode of the primary equipment (including the real remote signal obtained from the monitoring system and the virtual remote signal reported by the key), upload it to the control center through the network, and accept the operation ticket issued by the control center, so as to realize the issuance of tickets at any point, the receipt of tickets at any point, and the return of tickets at any point.

[0072] The system can simulate invoicing at the anti-error workstation in the centralized control center and the anti-error system in the substation. The operator first starts the five-prevention system, passes the identity authentication and logs into the system, and then performs simulated operations on the system. The system makes intelligent judgments on each operation based on the five-prevention rules compiled according to the requirements of the bureau. If the operation is correct and complies with the "five-prevention" operation rules, the next operation is allowed; if the operation is wrong and does not comply with the "five-prevention" operation rules, the device name and number of the wrong operation item will be displayed and the wrong operation type will be prompted by voice to prompt the operator to make corrections.

[0073] After the simulation operation is completed, the operator will transmit the operation ticket to the new generation centralized monitoring system for anti-error verification. If the verification is passed, it will be returned to the centralized control anti-error system. The centralized control anti-error system will send the approved operation ticket to the PMS system for the review process. If the review is passed, it will be returned to the centralized control anti-error system. The centralized control anti-error system will transmit the operation ticket to the corresponding controlled substation. The local operator will receive the operation ticket and transmit it to the computer key through the communication adapter for on-site operation; during the switching operation, the operator will insert the computer key into the coded lock of the corresponding lock, and use its coding head to detect whether the operation object is correct. If correct, the lock can be opened to perform the corresponding switching operation; if the wrong interval is entered or the operation is erroneous, the computer key will use voice to issue a warning to remind the operator of the type of error, thereby achieving the purpose of forced locking.

[0074] Business Process:

[0075] like Figure 3 The station-side error prevention system is a station-side five-prevention server, and the centralized control error prevention system is a centralized control error prevention server.

[0076] Process Description:

[0077] The operating personnel create a simulation rehearsal of the new operation task in the station-side anti-error system, and push it to the centralized control anti-error system after the logic verification is passed.

[0078] The centralized control and error prevention system will push the operation tickets that have passed the verification to the new generation centralized monitoring system for error prevention verification, and return them to the centralized control and error prevention system after passing the verification.

[0079] The centralized control and error prevention system pushes the verified operation ticket to the PMS system for circulation review process and associated transfer orders, and then returns it to the centralized control and error prevention system.

[0080] The centralized control and error prevention system will send the approved operation ticket to the corresponding station-side error prevention system. The operator will transfer the operation ticket to the computer key in the station-side error prevention system for on-site execution.

[0081] After the operation ticket is executed, the station-side error prevention system will return the operation ticket to the centralized control error prevention system, and the centralized control error prevention system will archive the operation information to the PMS system.

[0082] like Figure 4 The following is the sequential control operation process.

[0083] Process Description:

[0084] The monitoring system initiates a sequential control operation and calls a sequential control operation ticket, which is then sent to the centralized control and error prevention system after passing the error prevention check.

[0085] The centralized control and error prevention system receives the sequential control operation ticket and conducts a preview confirmation. After the error prevention check passes, the result is returned to the monitoring system.

[0086] The monitoring system issues an operation ticket execution command, and the corresponding controlled substation performs the sequential control operation.
