Description

Technical Field

[0002] With the development of science and technology and social industry, the power grid is becoming increasingly large and complex in structure. The number of operating equipment designed for the power industry is also increasing. The workload of power operators will become increasingly heavier, and the risk of misoperation borne by the management model used by the power grid that relies on operators is also increasing.

[0003] Electrical equipment is divided into three states: operation, standby (cold standby and hot standby), and maintenance; the process of changing the equipment from one state to another is called switching, and the operation performed is called switching operation; operating disconnectors, circuit breakers, and hanging and removing grounding wires to change electrical equipment from one state to another or changing the system's operating mode is called switching operation; switching operations must implement the operation ticket system and work supervision system to ensure safety.

[0004] At present, the existing switching operation process of the substation is that the staff of the dispatching center uses the OMS system to issue the switching order, and the operation and maintenance personnel use the PMS system to complete the manual ticket writing. After obtaining and printing the operation ticket, the operation and maintenance personnel use the substation anti-error host to perform the simulation rehearsal, anti-error verification, subpoena, and five-protection key unlocking operation procedures; among them, the main power safety issues are as follows: 1. Since there is no technical connection between the manually filled operation ticket and the substation error prevention host simulation rehearsal operation process, there is a risk of inconsistency between the ticket and the execution, which may cause on-site operation errors of the staff, resulting in safety accidents, damage to the substation electrical equipment, and endanger the personal safety of the operators; at the same time, since the PMS system adopts the manual ticket writing method, it is impossible to realize the online control of the whole process of dispatching orders, operation tickets, rehearsals, and operations, and it is impossible to carry out detailed control of the entire switching operation process, resulting in unknown safety hazards in the operation process; 2. Since the substation error prevention system uses a computer key subpoena, it is technically impossible to achieve step-by-step monitoring of the guardian and operator, and the personal safety of the operator cannot be guaranteed; 3. Since the five-defense systems are not connected to the Internet or the networking rate is low, each substation's safety-related edge devices such as the safety tool system, pressure plate monitoring system, grounding wire management system, and unlocking key management system have become information islands, failing to effectively integrate and utilize the edge device data in the substation, and failing to provide a decision-making basis for safe production management.

[0020] In summary, the power safety error prevention system based on 5G communication technology described in the present invention uses 5G network to communicate and connect edge devices with edge cloud, edge cloud with core cloud, core cloud with error prevention system, cloud platform module and electronic ticket terminal mobile terminal, thereby realizing data interaction between edge devices and edge cloud, edge cloud with core cloud, core cloud with error prevention system, cloud platform module and electronic ticket terminal mobile terminal; the 5G network supports massive edge computing device access technology of 5G mobile communication, including ubiquitous access capability for multiple channel media, supporting multiple communication modes such as TCP, UPD, serial port, supporting multiple protocols such as IEC104, IEC103, CDT, UDP, Modbus, IEC61850, webservice, etc., realizing access of edge devices of various types and functions, and at the same time using 5G communication to realize the interconnection of edge devices, realize information interaction between edge devices and data communication with edge cloud; On the basis of the existing power safety and error prevention technology, the dynamic networking of 5G mobile communications is used to realize the access of edge devices such as substation pressure plate measurement and control, grounding wire measurement and control, IoT locks, safety tools, unlocking key management machines, video surveillance, mobile terminals, and monitoring systems; edge devices use 5G communication modules to form an edge device information network, and encrypt various edge device information data and send them to the edge cloud. At the same time, with the help of the powerful functions of 5G communications, interactive communication between edge devices is realized, that is, using the 5G network, the edge device information is transmitted through cloud computing and then interacted and integrated with the power safety and error prevention system; among them, in order to realize ubiquitous access to edge device information and edge device information collection, different protocols are selected according to business scenarios. When it is point-oriented, it is mainly accessed through the IEC60870-5-104 protocol, when it is object-oriented, it is mainly accessed through the IEC61850 protocol, and when it is mobile terminal-oriented, it is accessed through the Webservice security protocol.

[0021] In the power safety error prevention system based on 5G communication technology described in the present invention, the cloud computing of massive edge device information is decomposed into two parts, the core cloud and the edge cloud, through the edge cloud and the core cloud, as well as the 5G network; Among them, the edge cloud is an independent cloud computing system, close to the edge device side, which integrates and roughly processes the information of nearby edge devices, and undertakes user query and interactive services; specifically, the edge cloud is composed of server nodes distributed in the same area, which specifically handles the service requests of users in the area and provides cloud computing services to users quickly and flexibly; each edge cloud is connected through a backbone network, and users log in to the edge cloud with the nearest geographical location through the network to use the services provided by the edge cloud nearby; on the one hand, the edge cloud is responsible for processing the data flow between the core cloud and the user terminal (edge ​​device) (such as compression, encryption and decryption, etc.), using the correlation between communication data to reduce network overhead, reduce latency, and ensure cloud computing QoS; on the other hand, the edge cloud stores the common data and commonly used data required by the terminal to access cloud computing services; The core cloud is a special cloud computing system responsible for managing and monitoring the resources and services in each edge cloud, and coordinating the edge clouds to jointly complete the cloud computing services required by users. Specifically, the core cloud is connected to each edge cloud through a 5G network and has a core resource manager. The core cloud monitors and grasps the services and resources provided by each edge cloud, and grasps the operating status and resource usage of each edge cloud computing service in real time. By collecting the services and resources provided by each edge cloud, the core cloud coordinates and dispatches the resources and services in each edge cloud to provide users with more powerful cloud computing services. The collaboration between edge cloud and core cloud is manifested in the following aspects: core cloud provides services such as coordination, monitoring, and scheduling of resources and services of each edge cloud; edge cloud provides specific cloud computing service functions such as computing and storage, and stores common data and user frequently used data required by storage terminals to access cloud computing services. Under the coordination of core cloud, cloud computing services are provided transparently to users.

[0022] There are multiple error prevention systems in the power safety error prevention system based on 5G communication technology described in the present invention, and each error prevention system can exchange information with other safety zones, integrate all error prevention systems, and obtain a cross-zone comprehensive active error prevention system that integrates massive information; wherein, the cross-zone comprehensive active error prevention system that integrates massive information includes B / S and C / S hybrid application modes, MVC multi-layer design, unified data model, standardized data interface, and uses dynamic networking technology, Internet of Things technology, and 5G communication technology to achieve the access of multiple edge devices such as substation pressure plate measurement and control, grounding wire measurement and control, Internet of Things locks, safety tools, unlocking key management machines, video surveillance, mobile terminals, and monitoring systems, and build an autonomous and controllable power safety error prevention system based on edge device information fusion, and the system integrates information data of various edge devices; After integrating massive edge device information, the data information of the power safety error prevention system is relatively complex, and large-scale cross-regional interaction requires solving problems such as compatibility, encapsulation, and encryption. The cross-regional comprehensive active error prevention system that integrates massive information mainly solves the cross-regional interaction of error prevention system information through the following methods: 1. Communication protocol proxy The communication protocol agent is a protocol encapsulation for data access to various business modules in the whole network, including database transfer agent, file transfer protocol (FTP), data collection and forwarding agent (104 / 101 protocol), etc. For business systems using relational databases, open database interconnection (ODBC) is used for interface access; for business systems using file transfer protocol transmission, file-type data is accessed according to FTP standards; for business systems based on real-time data, data forwarded by real-time systems is received according to IEC60870-5 series protocols; the core feature of the communication protocol agent is to provide access interfaces for different data sources, and convert the received data into standard XML files according to the unified data format formulated by the data unification platform.

[0023] 2. XML-based data unified platform The data unification platform develops a unified XML-based storage and presentation method to address the heterogeneity and looseness of data in each business module. First, XML files are full-text-based interpreted data files that meet the data transmission requirements for isolation devices. Second, XML files are not only conducive to data presentation, but can also encapsulate business logic structures. They are well-structured for the actual data sources of each business system and can perform good data mapping. Third, the biggest difference between XML and other data presentation forms is that it is extremely simple, easy to read and extensible for external sharing of data.

[0024] The data unification platform develops a system-specific data dictionary and data description, and builds an XML-based database; in actual applications, dictionary mapping is first performed for different businesses to ensure the uniqueness of keywords and data; dictionary data tables mostly use whole-table storage, while various raw and cooked data tables mostly use incremental storage, that is, each time the data is stored, the data that is added or changed after the last data storage is stored; data storage includes multiple storage modes: storing dictionaries (that is, table structures) and data, storing only data, storing only as local files, storing only in local databases and transmission rule tables, etc.; initiating a connection with the management information region database through a data communication agent and performing one-way data transmission; after the management information region platform receives the data and verifies it successfully, it parses the data and adds it to the database to achieve data sharing.

[0025] 3. Data Summarization and Management Technology Through data summarization and management, cross-regional information interaction to prevent misinformation is easier and more compatible. Data management technology mainly includes task scheduling, data maintenance management, data monitoring, etc. Task scheduling is responsible for the access frequency, storage interval, task execution and stop of the data of each business module of the integrated scheduling; Data maintenance management is mainly responsible for the maintenance of the stored data, including data backup, data increase and decrease, access interface start and stop, data proxy protocol increase and decrease; Data monitoring provides data section monitoring, internal and external network interaction data, communication monitoring and log recording and other functions.

[0026] The specific process of automatically generating a switching operation ticket in the power safety error prevention system based on 5G communication technology of the present invention includes: Through the operation information determination module in the core cloud, according to the fusion information of each edge cloud, combined with the analysis of the dispatch instructions issued by the dispatch center, the operating equipment, the topological information, initial state and target state of the operating equipment, as well as the operation type and operation parameters are determined; through the operation ticket intelligent generation module in the core cloud, based on the power grid topology and power grid data model, according to the operation type corresponding to the dispatch instruction, the operation steps in the operation ticket expert library module corresponding to the current operation type are determined; the internal operation reasoning control unit is called to automatically generate an operation ticket based on the operation steps in the operation ticket expert library module corresponding to the current operation type, combined with the topological information, initial state and target state of the operating equipment.

[0027] The electric power safety error prevention system based on 5G communication technology described in the present invention involves safety zone I and safety zone IV. Safety zone I and safety zone IV are connected with the server of safety zone I and the server of safety zone IV through forward and reverse isolation, and the isolation of each major zone is realized; Among them, the security zone I includes multiple anti-error systems, each of which includes a comprehensive anti-error server and a comprehensive anti-error workstation host; the comprehensive anti-error server mainly realizes the operation error prevention function, and the comprehensive anti-error workstation host realizes human-computer interaction. The operator can complete the operation ticket logic verification and transmit the electronic ticket at the workstation.

[0028] Among them, the security zone IV includes the security zone IV server and the security zone IV business workstation host; The security IV zone server includes two-ticket system modules, a video platform module, a PMS system module, and a cloud platform module; the two-ticket system module is the Web terminal for operation tickets and work tickets, which is convenient for two-ticket query and statistics; the video platform module can realize operation linkage with primary and secondary equipment in the substation, and reflect the equipment status in real time; the PMS system module can realize two-ticket archiving and query statistics; the business workstation host provides a human-computer interaction platform; the cloud platform module stores massive data and calculation requests, etc., and is connected to the electronic ticket mobile terminal through 5G network communication. The electronic ticket mobile terminal is convenient for operation and maintenance personnel to operate and use.

[0029] The safety zone IV business workstation host is placed in the safety zone IV and is connected to the safety zone IV server via a network cable to achieve human-computer interaction.

[0030] Based on the research on error prevention of the whole process of switching operation based on 5G communication technology, the electric power safety error prevention system based on 5G communication technology designed in the present invention aims to: in view of the current situation that the five protection systems, lock control systems, unlocking management, grounding wire management, video monitoring, lighting systems, etc. of each substation of the power supply company are relatively independently operated, use advanced new technologies such as "big cloud, Internet of Things, mobile, and intelligent chain" to deepen the application of scientific and technological innovation, management innovation and other achievements, open up the data channels of various business systems of the substation, perceive and identify each business system, carry out research on the interconnection and interoperability between various business systems of the substation, create a cross-regional comprehensive active error prevention system integrating massive information, and realize the intelligent generation of operation tickets based on 5G interconnection and edge device information fusion, so as to enhance the controllability of on-site operation safety and the penetration of operation and inspection management, and truly realize the controllability, controllability and controllability of on-site operation of substation.
