Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power systems, and more specifically, to a relay protection master station simulation system, a simulation deployment platform and a relay protection master station upgrade test method. Background Art

[0002] The relay protection master station is an important power system control center. Each relay protection master station corresponds to many substations, and each substation may include up to hundreds of relay protection devices. With the access of a high proportion of new energy, abnormal operation of the power grid occurs from time to time, and the power system regulation and fault mechanism are more complicated. Therefore, the power master station may face huge pressure of relay protection action events in a short period of time.

[0003] On the one hand, the operation of the power main station itself is relatively complex. Facing huge regulatory pressure, it needs to be upgraded from time to time, and the upgrade process can easily affect the stable operation of the power main station. On the other hand, complex fault events in a short period of time also put forward higher requirements on the professional level of relay protection operation and maintenance personnel. Relay protection operation and maintenance personnel need to continuously improve their emergency response skills. At present, the way for relay protection operation and maintenance personnel to improve their emergency response skills is mainly through skills training. The current training method is mainly carried out in the form of offline materials such as learning regulations, which is difficult to systematically reflect the problems and phenomena in the fault and abnormal process. The operation and maintenance personnel lack actual operation and disposal, and their experience and skills are difficult to improve. Moreover, it is impossible to directly perform actual operations in the operation of the power main station in order to improve the skills of the operation and maintenance personnel.

[0004] A simulation system is a computer system used to simulate a real system. It can simulate various dynamic processes of the real system in real time and provide a highly simulated simulation environment for testing, verifying and optimizing the performance of various practical applications.

[0005] How to apply simulation to relay protection master stations, simulate various dynamic processes of relay protection master stations without affecting the operation of actual power master stations, provide operation and maintenance personnel with training close to actual scenarios, and avoid pre-upgrade testing on actual power master stations, has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the problem of how to simulate various dynamic processes of the relay protection master station without affecting the operation of the actual power master station, provide operation and maintenance personnel with training close to actual scenarios, and avoid the problem of pre-upgrade testing on the actual power master station, the present invention proposes a relay protection master station simulation system, a simulation deployment platform and a relay protection master station upgrade test method, which improves the skill level of relay protection operation and maintenance personnel and ensures the reliable operation of the relay protection master station.

[0051] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0052] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment proposes a relay protection master station simulation system, see Figure 1 , including: data synchronization module, data processing module, operation and maintenance training module and testing module.

[0055] Among them, the data synchronization module is connected to the actual relay protection master station system, and is used to receive the relay protection master station model, state section, operation information and operation files transmitted by the actual relay protection master station system in real time, and synchronize the actual relay protection master station model, state section, operation information and operation files to the relay protection master station simulation system; the state section here can refer to the state of the actual relay protection master station system at a certain moment. The data processing module is used to receive the relay protection master station model, state section, operation information and operation files that have been synchronized with the actual relay protection master station system from the data synchronization module, and process them to form historical status data and real-time status data. The operation and maintenance training module is used for instructors and relay protection operation and maintenance personnel to call historical status data and real-time status data to perform relay protection simulation training tasks. The test module is used for testers to call historical status data and real-time status data to perform scenario function testing on the relay protection master station simulation system.

[0056] The relay protection master station simulation system proposed in this embodiment receives and synchronizes the relay protection master station model, status section, operation information and operation files transmitted by the actual relay protection master station system in real time, and then performs data processing. In the simulation system, historical status data corresponding to the historical status of the actual relay protection master station system and real-time status data corresponding to the real-time status of the actual relay protection master station system are formed, which is convenient for simulating various dynamic processes of the actual relay protection master station. On this basis, it is convenient to provide operation and maintenance personnel with training close to actual scenarios and to facilitate testers to conduct scenario function testing on the relay protection master station simulation system, thereby improving the skill level of relay protection operation and maintenance personnel.

[0057] The data synchronization module uses a two-way soft switch to synchronize the actual relay protection master station model, state section, operation information and operation files. After a specific time is set, the two-way soft switch is closed unidirectionally from the actual relay protection master station system to the data synchronization module, and the actual relay protection master station system transmits the relay protection master station model, state section, operation information and operation files to the data synchronization module. The relay protection master station model, state section, operation information and operation files are transmitted in the form of data stream messages. According to needs, the data synchronization module controls whether the actual relay protection master station system is synchronized with the simulation system through a two-way soft switch to realize the update management of the basic model and data of the simulation system.

[0058] Figure 2 The software function diagram of the data synchronization module is shown as follows: Figure 2 As shown, the software functions of the data synchronization module may specifically include data message monitoring, model information synchronization, and disk file monitoring of the relay protection master station. More specifically, in this embodiment, when the relay protection master station model is synchronized, if the relay protection master station model changes, the changed relay protection master station model information is automatically exported as a file, and then the relay protection master station model file is synchronized to the data synchronization module in the form of a data stream message, and the data synchronization module automatically restores it; when the operation information is synchronized, the data synchronization module automatically copies the real-time data stream message carrying the operation information for instant synchronization; when the operation file is synchronized, the data synchronization module dynamically monitors the generation and change of the operation file, monitors the behavior of the relay protection master station system receiving the operation file from the substation or the relay protection master station system generating a new operation file, and synchronizes the monitored new operation file to the data synchronization module in the form of a data stream message. The synchronized files include but are not limited to SVG graphic files, recording files, model files, various analysis results, and harmonic result data files. This example adopts a combination of file monitoring, data surveillance and real-time data message transmission to achieve the synchronization of the relay protection master station model, operation information and operation files from the actual relay protection master station system to the relay protection master station simulation system.

[0059] In addition, see Figure 2The data synchronization module is also used to send the tested and qualified software upgrade package to the actual relay protection master station system for software upgrade of the actual relay protection master station system. Specifically, after the upgrade software is tested and verified, the relevant upgrade software is packaged, and then the software package is instantly synchronized to the software upgrade directory of the actual relay protection master station system through the operation interface.

[0060] The data processing module receives the relay protection master station model, status section, operation information and operation files that have been synchronized with the actual relay protection master station system from the data synchronization module and is divided into: event notification information, call result information, analysis result information, equipment status, real-time library data and historical data. The data processing module performs processing operations on the relay protection master station model, status section, operation information and operation files including: data analysis, comparison and cleaning, see Figure 3 Then call the database interface and real-time library interface modules to complete the data update in the historical library and real-time library and the data storage management related business in the historical library.

[0061] like Figure 4 As shown, this embodiment proposes another structure of the relay protection master station simulation system. Figure 1 In addition to the structure shown, it also includes: a login management module, a preset plan execution service module, a substation simulation module, a communication service module and a storage module, wherein the login management module registers the login of the relay protection master station simulation system as a unique identity ID; the login includes instructors, relay protection operation and maintenance personnel and testers; the preset plan execution service module is used to cooperate with the operation and maintenance training module to execute the operation and maintenance training service plan, cooperate with the test module to execute the test service plan, the substation simulation module is used to simulate the actual substation, and the communication service module is used to establish communication between the substation simulation module, the actual substation, the operation and maintenance training module, the test module and the login management module. The storage module includes a historical status data storage module and a real-time status data storage module, the historical status data storage module is used to store historical status data, and the real-time status data storage module is used to store real-time status data.

[0062] Combination Figure 4 The specific structure of the data processing module is as follows:

[0063] Among them, event notification information, summon result information, and analysis result information are updated to the data storage module; the storage module realizes the real-time library and historical library functions; the real-time library function realizes the storage of memory data, which is the latest status data, including but not limited to the latest status of equipment status, operation information and analysis and inspection results, and the historical library function stores data including the latest status data and historical status data, including but not limited to the latest status of equipment status, operation information and analysis and inspection results.

[0064] Among them, event notification information mainly includes but is not limited to: equipment communication status, equipment operation status, plant communication status, equipment action events, equipment alarm events, equipment input quantity change, and new recording file notification; compare the equipment status and plant status with the original status, and transfer the data to the storage module for update when there is a change; parse the action, alarm, and change information messages, convert them into descriptions, status, and time, determine whether the value range of each information is reasonable, and then mark and clean the maintenance data, unreasonable values, or invalid data, and then transfer them to the storage module; parse the file name, time, and fault file information of the new recording notification, check the rationality of the data, find out whether the file already exists locally and mark it, and then transfer it to the storage module for processing.

[0065] The call result information includes but is not limited to: equipment set value, set value area code, analog quantity, pressure plate, input quantity, recording file, and general file; compare the set value, set value area code, pressure plate status, and input quantity with the previous value in the database. When any item changes, transfer it to the storage module for processing; parse the recording file name and time information, and then search in the database for the corresponding record. If it exists, the storage module will be handed over to update the download status. If it does not exist, the storage module will be handed over to add a new file record.

[0066] Analysis result information includes but is not limited to: automatic analysis results of recording files, fixed value inspection results, pressure plate status inspection results, fault report analysis results, switch quantity inspection results, automatic statistical analysis results, etc.

[0067] The above-mentioned analysis and statistical results need to be updated to the database, and the corresponding analysis details need to be saved in the form of files on the disk.

[0068] The update of equipment status includes but is not limited to: the set value, soft pressure plate, hard pressure plate, analog quantity, current set value area code, operation status, communication status under the current set value area code of each device; the latest status of the plant and channel status, the latest status of the equipment action signal and the alarm signal, which are updated to the real-time library as memory.

[0069] Historical data management: historical data is stored in the history library, including the latest status of the aforementioned equipment, action events, alarm events, position change records, plant station communication status change records, waveform file records, various analyses, inspection results, and statistical historical information; historical data is stored and managed in tables by year; when the disk exceeds the limit, the data is automatically cleared.

[0070] In addition, the data processing module only updates the status of the plant and equipment models in the real-time library, and is prohibited from affecting the relevant plants in the training library.

[0071] In this embodiment, the login management module has service management functions, including but not limited to: registration, information subscription, deregistration management, service cache, and service call;

[0072] Specifically, there are three types of roles:

[0073] Service provider: When starting up, it calls the registry client to register its own service with the registry. During operation, it sends heartbeats to the registry regularly to report its own survival status:

[0074] Service consumer: When starting up, it subscribes to the service from the registration center by calling the registration center client, caches the service list returned by the registration center locally, then selects a service node from the local cache service list, initiates a connection with the service provider, and completes the service call;

[0075] Service Registration Center: Used to save the registration information of service providers. When the status of the service provider changes, the services saved by the registration center will change dynamically and notify the service consumers of the changes synchronously.

[0076] In addition, the operation and maintenance training module, test module, preset plan execution service module and communication service module call the login management module to register with the registration center to realize information interaction. Therefore, the login management module has the function of authority management. All functional modules can set corresponding access rights for different users, record the key operations of users, including user name, execution operation, execution time, execution machine, etc., and provide query and retrieval functions for operation records; the user level is classified and customized as follows: (1) Ordinary users: only authorized to access and browse the relevant applications of the simulation test master station, which does not affect the safe and stable operation of the simulation system; (2) Instructor group: has all the permissions of ordinary users and has the permissions of instructors, such as making plans, editing lesson plans, and controlling the training process; (3) Trainee group: has all the permissions of ordinary users and has the permissions of trainees, such as executing training plans and different simulation training operations; (4) System administrator: has the highest authority. In addition to having all the above personnel permissions, it can also authorize various types of personnel; (5) Security auditor: conduct security audits on the operations of other users, such as log audits and important event audits; user logins must be verified, and the system will be automatically locked if it is not operated for a long time.

[0077] The preset plan execution module automatically executes related services according to the preset plan; when used in conjunction with the operation and maintenance training module, it automatically executes the corresponding processing according to the preset plan in the teaching plan to cooperate with the students to complete the simulation training application, including receiving the relevant training plan sent by the instructor management system, executing the relevant timed event plan according to the teaching plan requirements, and sending relevant notifications to designated students according to the teaching plan requirements; when used in conjunction with the test module, it executes periodic related services, including but not limited to automatic calling and automatic verification.

[0078] like Figure 5As shown, the communication service module realizes the communication service between the simulation substation module or the actual substation and the login management module, the operation and maintenance training module or the test module and the login management module through the message bus; the sending object and the receiving object are connected to the bus through the bus client, and the receiving object can register the message type of interest; the sending object sends a message to the bus, and the bus enters different message queues for management according to the subscription center strategy and different message types, and then the message distribution module completes the push of the message to the receiving object. The communication service module also supports the simulation system to receive the model and real-time data of the production system, completes the update of the basic model and state section, supports receiving the teaching plan information of the operation and maintenance training module and starts the execution as planned, and connects the simulation substation with the actual substation.

[0079] Example 2

[0080] like Figure 6 As shown, this embodiment proposes a relay protection master station simulation system deployment platform, which is used to deploy the relay protection master station simulation system described in Example 1, including: a data synchronization server, a platform server, a professional business server, and also includes: a substation server and a storage server. The relay protection master station simulation system deployment platform proposed in this embodiment is based on the digital twin concept and simulates the operation of the actual relay protection master station system.

[0081] Among them, the data synchronization server is used to deploy the data synchronization module and the data processing module. On the data synchronization server, the data synchronization module synchronizes the actual relay protection master station model, state section, operation information and operation files to the relay protection master station simulation system, and sends them to the platform server after being processed by the data processing module;

[0082] The platform server, based on the digital twin technology, establishes the same operating system and general business programs as the actual relay protection master station system, and is consistent with the general business functions of the actual relay protection master station system, simulating the operation of the actual relay protection master station system; in specific implementation, the actual relay protection master station system is simulated based on the mirroring technology, and the mirroring technology mainly includes data mirroring and port mirroring. Data mirroring is a type of cluster technology, which is to mirror the hard disks of two servers built on the same local area network through software or other special network devices. The master / slave servers monitor each other's operating status through the heartbeat monitoring line. When the master server stops due to a fault, the slave server will take over the application of the master server in a very short time. This technology is widely used in data backup and system testing of large-scale IT information systems. Port mirroring is to copy the message of the specified port or the message that meets the specified rules to the destination port. This technology is widely used in the field of switches, message analysis and monitoring to achieve network supervision and troubleshooting.

[0083] The professional business server is used to deploy operation and maintenance training modules and test modules, and is provided with operation and maintenance training professional business programs and test professional business programs. The operation and maintenance training professional business programs provide relay protection operation and maintenance training simulation scenarios, and the test professional business programs provide functional test scenarios.

[0084] The deployment platform proposed in this embodiment establishes the same operating system and general business procedures as the actual relay protection master station system, is consistent with the general business functions of the actual relay protection master station system, simulates the operation of the actual relay protection master station system, and creates an application precedent based on mirror full-environment pre-testing for the relay protection master station.

[0085] Example 3

[0086] This embodiment proposes a relay protection master station upgrade test method, the flow chart is shown in Figure 7 ,include:

If so, send the software upgrade package from the data synchronization module of the relay protection master station simulation system to the actual relay protection master station system. Otherwise, return the software upgrade package to the factory for maintenance.

[0089] By using the method proposed in this embodiment, the software upgrade package is pre-tested using the relay protection master station simulation system without affecting the actual operation of the relay protection master station, thereby ensuring the safe and reliable operation of the relay protection master station.
