Technical Field

[0001] The invention relates to the technical field of industrial automation, and in particular to a thermal power plant simulation system and a method, device and medium for saving operating conditions during operation thereof. Background Art

[0002] With the rapid development of the power industry, thermal power plants, as an important base for energy conversion, are increasingly concerned about their safety and economy. In order to improve the operating efficiency of thermal power plants, reduce operating risks, and strengthen the training of power plant operators, thermal power plant simulation systems have emerged. This simulation system can simulate the real working conditions of thermal power plants, providing strong support for power plant operation management, personnel training, and teaching research.

[0003] Traditional thermal power plant simulation systems mainly rely on physical models and mathematical algorithms to simulate the operating status of thermal power plants. These systems can simulate basic operating conditions such as startup, normal operation, and shutdown of power equipment, and simulate accidents to a certain extent. However, when simulating complex operating conditions and dynamic processes, these systems often have problems such as low accuracy and poor real-time performance, which makes it difficult to meet the requirements of modern thermal power plants for simulation accuracy.

[0004] In addition, the traditional thermal power plant simulation system also has shortcomings in the preservation of configuration conditions. Due to the lack of effective configuration condition preservation methods, when a specific condition needs to be reproduced or compared, it often takes a lot of time and resources to rebuild the simulation model, resulting in low work efficiency. At the same time, due to the large amount of saved data and complex formats, data management and maintenance have become very difficult. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a thermal power plant simulation system and a method, device and medium for preserving the operating conditions during operation thereof in view of the deficiencies in the above-mentioned prior art, so as to solve the technical problem that the lack of operating condition preservation in the current thermal power plant simulation system leads to difficulties in subsequent data analysis and the inability to quickly reproduce the operating conditions.

[0006] The objective of the present invention is achieved by the following technical solutions: In a first aspect, the present invention provides a method for saving operating conditions of a thermal power plant simulation system during operation, comprising: When the working condition saving communication interface receives the working condition saving command sent by the management computer in the thermal power plant simulation system, the configuration of all controllers in the thermal power plant simulation system during operation is saved according to the working condition saving command to obtain a working condition file; the working condition saving communication interface is set in the controller in the thermal power plant simulation system; After the working condition file is transmitted to the management machine through the set channel in the working condition saving communication interface, the management machine returns an instruction indicating that the working condition has been successfully saved.

[0007] As a further improvement of the present invention, the configuration of all controllers in the thermal power plant simulation system during operation is saved according to the operating condition saving command to obtain the operating condition file, which specifically includes: The management machine sends a pause or stop command to all controllers in the thermal power plant simulation system. After receiving the pause or stop feedback command from the controller, the management machine changes the current working condition saving state of each controller and sends a working condition saving command to each controller. After receiving the working condition save command, the controller traverses the controller algorithm page file, reads the algorithm page file into the memory file, extracts the variable value of the current controller operation algorithm according to the algorithm page file structure, reads the variable value into the memory file, and compresses all temporary files of the controller to obtain the working condition file.

[0010] As a further improvement of the present invention, the working condition file is transmitted to the management machine through a set network channel, specifically including: During the transmission of the working condition files, the working condition files are divided into packages according to the set transmission rate, and the divided working condition files are transmitted to the management machine respectively; After the working condition file is transmitted to the management machine, it is stored in the format of a temporary file; After storing the temporary file, the management machine verifies the integrity of the working condition file in real time. When the working condition file is damaged or lost, the management machine feeds back fault information to the controller corresponding to the damaged working condition file. The corresponding controller transmits again according to the fault information; The management machine stores the retransmitted operating condition file and performs integrity verification until the integrity verification of the operating condition file passes, and then returns an instruction to the corresponding controller indicating that the operating condition file has been successfully saved.

[0011] As a further improvement of the present invention, after the management machine receives the working condition files of all controllers, it deletes the temporary files of all controller working condition files, and returns an instruction of successful working condition saving to the controller through the working condition saving communication interface, and the management machine records the detailed information of this saving operation.

[0012] As a further improvement of the present invention, the working condition saving communication interface adopts the TCP protocol and the UDP protocol in the TCP / IP network communication protocol.

[0013] In a second aspect, the present invention further provides a thermal power plant simulation system for implementing the above-mentioned method for saving operating conditions during operation of the thermal power plant simulation system, the system comprising a management machine and a plurality of controllers; the controller is provided with an operating condition saving communication interface; When the working condition saving communication interface receives the working condition saving command sent by the management machine, it sends it to the controller; The controller saves the configuration during operation according to the working condition saving command to obtain a working condition file, and transmits the working condition file to the management machine through a set channel in the working condition saving communication interface; After receiving the working condition file corresponding to the controller, the management machine returns an instruction of successful saving of the working condition to the corresponding controller.

[0014] In a third aspect, the present invention also provides a computer-readable storage medium storing one or more programs, wherein the one or more programs include instructions, which, when executed by a computing device, enable the computing device to execute the above-mentioned method for saving operating conditions during operation of a thermal power plant simulation system.

[0015] In a fourth aspect, the present invention further provides a computing device, comprising: One or more processors, a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs include steps for executing the above-mentioned method for saving operating conditions during operation of a thermal power plant simulation system.

[0017] An embodiment of the present invention provides an electronic device, comprising a computer program, which, when executed by the electronic device, implements the steps of the method for saving operating conditions of a thermal power plant simulation system during operation.

[0018] The beneficial effects of the present invention are as follows: the operating condition saving method of the thermal power plant simulation system provided by the present invention can quickly respond to the operating condition saving command of the management machine by setting the operating condition saving communication interface in the controller, and timely save the configuration information of the controller, thereby reducing the time of data transmission and processing. By saving the operating condition file regularly or on demand, it can be ensured that when a failure or abnormality occurs in the system, it can be quickly restored to the previous stable state, thereby improving the reliability and stability of the system. The operating condition file records the operating status and configuration information of the system at different time points, which provides valuable data support for subsequent troubleshooting and debugging. By comparing the operating condition files at different time points, the problem can be quickly located and corresponding solutions can be taken. When the operating condition saving communication interface receives the command, it can independently complete the task of operating condition saving and file transmission, reducing the dependence on other systems and improving the reliability of the system. Through the automated operating condition saving and transmission method, it is helpful to realize the intelligent management of the thermal power plant simulation system and improve the efficiency and accuracy of management. At the same time, the operating condition state can be reproduced through the saved operating condition data information, providing a reliable basis for subsequent data analysis and tracing.

[0019] Furthermore, by setting up channels for file transfer and performing identity authentication and encrypted communication, data can be effectively prevented from being stolen or tampered with, thereby improving the security of the system.

[0020] Furthermore, the management machine sends a pause or stop command to make the controller enter a stable state before saving the working condition, avoiding data inconsistency or errors that may be caused by saving during the operation of the controller, ensuring the stability of the system. After the controller receives the working condition save command, it can accurately save the current controller's operating state to the memory file by traversing the algorithm page file and extracting variable values, thereby realizing accurate preservation of the working condition. All temporary files of the controller are compressed to obtain the working condition file, which reduces the amount of data in the file, and also reduces the risk of data damage or loss during transmission and storage, thereby improving data integrity.

[0021] Furthermore, by registering the controller's working condition saving communication interface digital certificate and user name and password information in the management machine, and transmitting and verifying them when sending the working condition saving command, unauthorized access can be effectively prevented, thereby enhancing the security of the system. The access rights to the communication interface are determined according to the permissions of each controller, and precise permission management is achieved to ensure that each controller can only access its authorized functions and data, thus avoiding the abuse of permissions. Strict identity authentication and permission control mechanisms help reduce system failures caused by illegal access or erroneous operations, and improve the stability of the system.

DETAILED DESCRIPTION

[0024] In order to make the purpose and technical solution of the present invention clearer and easier to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The concept of the present invention is to provide a thermal power plant simulation system and a method, device and medium for saving operating conditions during operation thereof. The specific steps of the operating condition saving method are as follows: When the working condition saving communication interface receives the working condition saving command sent by the management computer in the thermal power plant simulation system, the configuration of all controllers in the thermal power plant simulation system during operation is saved according to the working condition saving command to obtain a working condition file; wherein the working condition saving communication interface is set in the controller in the thermal power plant simulation system; After the working condition file is transmitted to the management machine through the set channel in the working condition saving communication interface, the management machine returns an instruction indicating that the working condition has been successfully saved.

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments, wherein the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1 like Figure 1-Figure 2 As shown, this embodiment provides a method for saving operating conditions during operation of a thermal power plant simulation system, and the specific implementation method is as follows.

[0028] When the working condition saving communication interface receives the working condition saving command sent by the management machine in the thermal power plant simulation system, the running configuration of all controllers in the thermal power plant simulation system is saved according to the working condition saving command (used to build a monitoring and control system to realize the monitoring, control and management of the production process. Through configuration, the functions and behaviors of the system can be customized according to actual needs to meet specific application scenarios) to obtain the working condition file. Among them, the management machine is the working condition control center in the simulation system, which can realize remote monitoring and control of each controller.

[0029] The virtual controller in the simulation system is obtained according to the corresponding control part data of the actual thermal power plant, and the management machine is also a virtual device.

[0030] The working condition saving communication interface is set in the controller of the thermal power plant simulation system. The working condition saving communication interface covers three main functions: starting working condition saving, working condition file transmission, and working condition saving completion.

[0031] When the operating condition saving starts, the management machine sends a pause or stop command to all controllers in the thermal power plant simulation system. After receiving the feedback instruction of the pause or stop operation from the controller, the management machine changes the current operating condition saving state of each controller and sends the operating condition saving command to each controller. After the controller receives the working condition save command, it traverses the controller algorithm page file, reads the algorithm page file into the memory file, extracts the variable value of the current controller operation algorithm according to the algorithm page file structure, reads the variable value into the memory file, and compresses all the temporary files of the controller to obtain the working condition file.

[0032] Specifically, by starting the working condition saving function, the configurations of all controllers in operation can be completely saved and corresponding working condition files can be generated. In this embodiment, the working condition saving communication interface adopts the TCP protocol and the UDP protocol in the TCP / IP network communication protocol.

[0033] When executing this function, a pause or stop command will be sent to all controllers to ensure that the controller can enter a stable state in the shortest time. After receiving the pause or stop feedback from all controllers, the working condition saving status of all controllers is set to 1, and a working condition saving command is sent to all controllers. After receiving the working condition saving command, the controller will traverse the algorithm page file of the controller, read the algorithm page file P1 into the memory file M1, and then take out the variable value of the algorithm page memory M2 of the controller's current operation according to the structure of the algorithm page file, write it into the memory file M1 in sequence, and finally save the memory file M1 to the temporary storage file P1, which can accurately save the current controller's operation state to the memory file, thereby realizing accurate saving of the working condition. When all controllers have completed the traversal, the information that the current controller working condition has been successfully saved is returned to the working condition saving communication interface. Only when all controllers have successfully saved the working condition, the algorithm page files of all controllers will be compressed to form a compressed working condition file, and a successful signal will be returned to the working condition saving communication interface. All temporary files of the controllers are compressed to obtain working condition files, which reduces the data volume of the files, reduces the risk of data damage or loss during transmission and storage, and improves data integrity. Through this orderly control and storage process, the reliability of the system in working condition storage is enhanced, and system failures or abnormalities caused by improper working condition storage are reduced.

[0034] Secondly, after the working condition file is transmitted to the management machine through the set channel in the working condition saving communication interface, the management machine returns an instruction indicating that the working condition has been successfully saved.

[0035] During the transmission of the working condition file, the working condition file is divided into packets according to the set transmission rate (the working condition file is divided into data packets of set size), and the divided working condition files are transmitted to the management machine respectively; After the working condition file is transmitted to the management machine, it is stored in the format of a temporary file; After storing the temporary file, the management machine verifies the integrity of the working condition file in real time. When the working condition file is damaged or lost, the management machine feeds back fault information to the controller corresponding to the damaged working condition file. The corresponding controller transmits again according to the fault information; The management machine stores the retransmitted operating condition file and performs integrity verification until the integrity verification of the operating condition file passes, and then returns an instruction to the corresponding controller indicating that the operating condition file has been successfully saved.

[0036] After the management machine receives the working condition files of all controllers, it deletes the temporary files of all controller working condition files, and returns the instruction of successful working condition saving to the controller through the working condition saving communication interface. The management machine records the detailed information of this saving operation.

[0037] Specifically, after the working condition is saved successfully, the working condition file transfer function will be started immediately. This function will securely transfer the compressed file to the management machine through an encrypted network channel. During the transmission process, the system will monitor the transmission status in real time, including the stability of the network connection, the data transmission rate, and the integrity of the data. At the same time, the system will also take a series of data verification and error correction measures to ensure the accuracy and security of the data. If any abnormal situation is found during the transmission process, the system will immediately take corresponding measures to deal with it, such as resending data, adjusting transmission parameters, or issuing alarms.

[0038] After the working condition file is successfully transferred to the management machine, the system will automatically delete the compressed temporary files of all controller algorithm pages to free up storage space. At the same time, the system will return a successful save notification to the user through the interface so that the user can know the result of the working condition save in time. In addition, the system will automatically record the detailed information of this save operation, including the save time, the saved file name, the saved path, and related controller information. These records will greatly facilitate the subsequent working condition data management and retrieval. Users can quickly find the required working condition data by querying these records, and analyze and process them.

[0039] In order to ensure that the working condition files can be safely and accurately transmitted to the management machine, the simulation system will use an encrypted network channel for data transmission. This encryption measure can effectively protect the confidentiality and integrity of the data and prevent the data from being stolen or tampered with during the transmission process.

[0040] Among them, an encryption algorithm is set in the working condition storage communication interface of the controller, and the encryption algorithm is used to perform encrypted communication with the management machine; the encryption algorithm can adopt SM2 encryption algorithm, SM3 encryption algorithm or RSA encryption algorithm. Regardless of the algorithm, it is necessary to transmit the public key and private key, as well as the corresponding digital certificate to the management machine. The controllers in this embodiment can use one encryption algorithm.

[0041] During the transmission process, the system will monitor the transmission status in real time, including the stability of the network connection, the data transmission rate, and the integrity of the data. Through real-time monitoring, the system can promptly discover and solve possible problems to ensure that the data can be smoothly transmitted to the management machine. If the network connection is found to be unstable during the transmission process, the system will try to re-establish the connection or adjust the transmission parameters to ensure that the data can continue to be transmitted. If the data transmission rate is found to be too slow, the system will analyze the cause and take corresponding measures, such as optimizing network settings or increasing bandwidth, to increase the transmission rate. If the integrity of the data is found to be damaged, the system will take data verification and error correction measures to ensure that the data received by the management machine is complete and accurate.

[0042] In addition, the system will back up and archive the transmitted data to prevent data loss or damage. If an unexpected situation occurs during the transmission process and the data transmission is interrupted, the system can restore the data from the backup and retransmit it. This ensures that the working condition files can be safely transmitted to the management machine in the end, providing reliable data support for subsequent working condition management.

[0043] After the working condition file is successfully transferred to the management machine, all controller algorithm page compressed temporary files are automatically deleted to free up storage space and avoid wasting storage space. At the same time, a successful save notification is returned to the user through the interface, so that the user can promptly understand the result of the working condition saving, enhancing the user's trust and satisfaction with the system. In addition, when the working condition corresponding to a controller needs to be reproduced, the management machine transfers the corresponding working condition file to the corresponding controller, and the controller reproduces it according to the working condition file.

[0044] In addition, the system automatically records the detailed information of this save operation, including the save time, save file name, save path, and related controller information, which is very important for the subsequent operation data management and retrieval. Through these records, users can easily query and trace the historical operation data, and understand the operation status and parameter settings of the system at different time points. This is of great significance for system debugging, optimization, and troubleshooting. At the same time, these records also provide strong support for system maintenance and management, and help improve the reliability and stability of the system.

[0045] In addition, the controller and the management machine need to authenticate before transmitting data through the working condition storage communication interface, including: The management machine registers the working conditions of each controller and saves the digital certificate of the communication interface as well as the user name and password information; the access rights to the communication interface are determined according to the permissions of each controller; When the management machine sends a working condition saving command to each controller, the working condition saving communication interface digital certificate and user name and password information corresponding to each controller are transmitted to the corresponding controller; Each controller is configured according to the received user name and password information and the digital certificate of the working condition storage communication interface, and after the configuration is successful, a configuration success instruction is sent to the management machine.

[0046] Only successfully configured controllers can communicate with the management machine through the working condition saving communication interface.

[0047] In addition, the simulation system also regularly reviews and updates the identities and permissions of controllers to ensure that the permissions of controllers always match their responsibilities and roles. If the identity or permissions of a controller change, the management machine should update the relevant information in a timely manner and notify the corresponding controller.

[0048] In addition, in order to prevent unauthorized access, the system should also establish a logging mechanism to record all access attempts to the communication interface, including successful and failed attempts. This will facilitate post-event tracing and auditing, and timely discover potential security threats. Example 2 like Figure 2 As shown, in another embodiment of the present invention, a thermal power plant simulation system is provided, which can be used to implement the above-mentioned method for saving operating conditions during the operation of the thermal power plant simulation system. Specifically, the thermal power plant simulation system includes a management machine and several controllers; the controller is provided with an operating condition saving communication interface; Among them, when the working condition saving communication interface receives the working condition saving command sent by the management machine, it sends it to the controller; The controller saves the configuration during operation according to the working condition saving command, obtains the working condition file, and transmits the working condition file to the management machine through the set channel in the working condition saving communication interface; After receiving the working condition file corresponding to the controller, the management machine returns the working condition saving successful instruction to the corresponding controller.

[0049] The working condition saving communication interface is a universal interface module, which realizes the communication compatibility between different controller stations and reduces the complexity of the system.
