First, the distributed thermal power unit simulation system according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0053] In recent years, although some research has attempted to optimize the simulation system through virtualization technology or distributed computing, the following defects still exist: low modularity, the existing distributed solutions do not decouple the functional modules. For example, the control logic simulation and the physical model calculation still rely on the same computing node, resulting in uneven resource allocation. Insufficient dynamic management ability, lacking a unified centralized management module, unable to monitor the status of each sub-module in real time or dynamically adjust the task load, and the system has poor fault tolerance. Limited compatibility, it is difficult to integrate the controller protocols or device models of different manufacturers in a unified platform, which limits the adaptability of the simulation system to different unit models.

[0054] Based on the above problems, an embodiment of the present application proposes a distributed thermal power unit simulation system, which realizes the efficient operation and flexible expansion of the simulation system through modular design, distributed resource scheduling, security authentication mechanism and remote access support, meeting the diverse needs of the modern power industry for simulation technology.

[0055] The distributed thermal power unit simulation system will be elaborated in detail below.

[0056] Figure 1 It is a block diagram of a distributed thermal power unit simulation system according to an embodiment of the present application.

[0057] Exemplarily, as Figure 1 shown, the distributed thermal power unit simulation system 10 includes: a database service module 100, a centralized management module 200, an authorization and authentication module 300, an operator station module 400, an engineer station module 500, a virtual data processor module 600, a model service module 700, a Web service module 800, and a control module ( Figure 1 not shown in the figure).

[0058] Among them, the database service module 100 is used to record the operation status information of each functional module and control the status synchronization between functional modules; the centralized management module 200 is used to uniformly manage and control each functional module; the authorization and authentication module 300 is used to provide access control at different permission levels; the operator station module 400 is used to provide a human-machine interaction interface and establish a connection with the simulation machine core platform; the engineer station module 500 is used to edit the control logic of the simulation machine and configure system parameters; the virtual data processor module 600 is used to simulate the logical operations of the field control system using simulation algorithms; the model service module 700 is used to build a mathematical model of physical equipment and perform real-time simulation calculations; the Web service module 800 is used to provide a remote access interface based on network protocols for remote training based on the remote access interface; the control module is used to determine the module combination scheme of the distributed thermal power unit simulation system 10 according to the configuration parameters of the target thermal power unit, and select at least one functional module from the database service module 100, the centralized management module 200, the authorization and authentication module 300, the operator station module 400, the engineer station module 500, the virtual data processor module 600, the model service module 700, and the Web service module 800 according to the module combination scheme, and use at least one functional module to perform thermal power unit simulation training operations.

[0059] It should be noted that the distributed thermal power unit simulation system 10 in the embodiment of the present application adopts a modular distributed architecture design, dividing the entire system into eight functional modules including database service, centralized management, authorization and authentication, operator station, engineer station, virtual data processor (abbreviated as DPU), model service, and Web service, as well as a control module. Each functional module can be interconnected through a communication network, and in the actual use process of the distributed thermal power unit simulation system 10, the types and quantities of the included functional modules can be dynamically adjusted according to the capacity of the target unit and the hardware resource configuration, so as to achieve dynamic resource expansion.

[0060] Specifically, the database service module 100 is responsible for recording and storing the operation status information of each functional module, and realizing data (status) synchronization between functional modules to ensure the coordination of the entire distributed thermal power unit simulation system 10. The centralized management module 200 provides a unified management and control platform, which can centrally manage each functional module to improve the overall efficiency and response speed of the distributed thermal power unit simulation system 10. The authorization and authentication module 300, as the key to system security, is used to provide access control at different permission levels to ensure that only authorized users can access system resources, thereby guaranteeing the security and stability of the distributed thermal power unit simulation system 10. The operator station module 400 provides an intuitive human-machine interaction interface for operator users, enabling them to easily establish a connection with the simulation machine core platform and perform various operations. The engineer station module 500 allows engineer users to edit the control logic of the simulation machine and configure the parameters of the distributed thermal power unit simulation system 10 (such as algorithm configuration parameters, interface display parameters, communication protocol settings, etc.). The virtual data processor module 600 can use advanced simulation algorithms to simulate the logical operations of the field control system (the physical control system in the actual industrial environment). The model service module 700 can digitally model the dynamic behavior of real physical devices (such as boilers, steam turbines, generators, etc.) in the thermal power unit through mathematical equations and algorithms, and perform real-time simulation calculations. The Web service module 800 can provide a remote access interface based on network protocols, enabling users to remotely access the system through the network for training and operations, greatly improving the flexibility and usability of the distributed thermal power unit simulation system 10.

[0061] As the brain of the entire distributed thermal power unit simulation system 10, the control module can determine the module combination scheme of the distributed thermal power unit simulation system 10 according to the configuration parameters of the target thermal power unit (i.e., the capacity and hardware resource configuration of the target unit). According to the determined module combination scheme, the control module can select at least one functional module from the database service module 100, the centralized management module 200, the authorization and authentication module 300, the operator station module 400, the engineer station module 5x00, the virtual data processor module 600, the model service module 700, and the Web service module 800, and use these functional modules to perform thermal power unit simulation training operations to ensure the accuracy and effectiveness of the training.

[0062] It can be seen that the distributed thermal power unit simulation system 10 of the embodiments of the present application is uniformly monitored and scheduled through the centralized management module 200, and combines the high-precision simulation algorithm of the virtual data processor module 600 and the physical device simulation of the model service module 700 to support real-time interaction and multi-scenario training; at the same time, it provides a secure and reliable remote access capability based on the authorization and authentication module 300 and the Web service module 800. It significantly improves the simulation efficiency, management flexibility and cross-regional collaboration ability.

[0063] Next, the database service module 100, the centralized management module 200, the authorization and authentication module 300, the operator station module 400, the engineer station module 500, the virtual data processor module 600, the model service module 700 and the Web service module 800 will be introduced in detail.

[0064] Optionally, in some embodiments, the database service module 100 includes: a status storage unit, a data synchronization unit and a data storage unit. Among them, the status storage unit is used to record the operation parameters and health status of each functional module; the data synchronization unit is used to share cross-module data based on a preset publish / subscribe mechanism; the data storage unit is used to store simulation data.

[0065] Specifically, the database service module 100 is composed of a status storage unit, a data synchronization unit and a data storage unit. The status storage unit is responsible for collecting and saving various parameters used by each functional module during operation (such as operation parameters such as CPU occupancy, memory usage, network latency, etc.) and the health status indicators of the module itself, so as to monitor and maintain the operation status of each functional module in real time. The data synchronization unit can implement a publish / subscribe mechanism based on the MQTT (Message Queuing Telemetry Transport) protocol, establish a cross-module data channel, and realize the distribution and sharing of data such as operation instructions, simulation parameters, and alarm information, so as to ensure the consistency and real-time nature of the data. The data storage unit can adopt a time-series database storage structure to save a large amount of data generated during the simulation process (such as operation records, control logic change records, device model output data, etc.). These data are crucial for subsequent analysis, evaluation and decision support. In addition, the data storage unit can also perform data retrieval and playback according to multi-dimensional conditions such as time stamps and event types to ensure the security and recoverability of the data.

[0066] Optionally, in some embodiments, the centralized management module 200 includes: a resource monitoring unit, a task scheduling unit, and a fault handling unit. Among them, the resource monitoring unit is used to monitor the resource occupancy rate of each functional module; the task scheduling unit is used to allocate computing tasks according to the load condition; the fault handling unit is used to isolate the functional modules in abnormal states and restore the functional modules in abnormal states to the normal state.

[0067] Specifically, the centralized management module 200 is composed of a resource monitoring unit, a task scheduling unit, and a fault handling unit. The resource monitoring unit can monitor and analyze the resource occupancy of each functional module in real time to ensure the reasonable allocation and use of resources. Through real-time monitoring, it can timely detect abnormal fluctuations in resource utilization rates, providing guarantee for the stable operation of the distributed thermal power unit simulation system 10. The task scheduling unit can intelligently allocate simulation computing tasks according to the data provided by the resource monitoring unit and the current load condition of the distributed thermal power unit simulation system 10. By optimizing the utilization rate of computing resources through intelligent scheduling algorithms, it ensures that computing tasks can be processed in the shortest time, while avoiding waste and overload of resources. The fault handling unit can monitor the operating state of the distributed thermal power unit simulation system 10 in real time. Once it detects that a functional module is in an abnormal state, it can automatically isolate these faulty modules to prevent the problem from spreading and affecting the entire system. At the same time, the fault handling unit also has the ability to restore these functional modules in abnormal states to the normal working state, ensuring the continuity and reliability of the distributed thermal power unit simulation system 10. Through the collaborative work of these three units, the centralized management module 200 can ensure the efficient, stable, and secure operation of the entire system.

[0068] Optionally, in some embodiments, the authorization and authentication module 300 includes: an authentication unit, an access unit, and a tracking unit. Among them, the authentication unit is used to perform user identity authentication based on biometric recognition policies and / or dynamic token policies; the access unit is used to access resources and functions corresponding to the current user role based on a preset role-based access control policy; the tracking unit is used to track and record the operation behaviors of users.

[0069] Among them, the biometric recognition policy refers to using biometric features such as fingerprints and irises for verification. The dynamic token policy refers to using a one-time password generator (such as a mobile APP to generate dynamic verification codes) for verification. The preset role-based access control policy refers to defining role hierarchies (such as operator, engineer, administrator) and binding operation permissions according to roles (such as an operator can only view data, and an engineer can modify logic).

[0070] Specifically, the authorization and authentication module 300 consists of an authentication unit, an access unit, and a tracking unit. The authentication unit can perform user identity authentication based on multi-factor authentication methods, including biometric recognition strategies and dynamic token strategies. The access unit can ensure that users can access resources and functions corresponding to their current roles according to the preset role-based access control policy. The tracking unit can continuously track and record in detail the operation behaviors of users (recording metadata such as operation time, user identity, and executed actions), and generate audit logs for analyzing abnormal behaviors (such as illegal parameter modification and unauthorized operations) to ensure the transparency and traceability of operations.

[0071] Optionally, in some embodiments, the operator station module 400 includes at least one of a distributed human-machine interface, a real-time trend display window, and an alarm management console.

[0072] Specifically, in the embodiments of the present application, the operator station module 400 has a series of advanced functions to ensure the efficiency and security of operations. This module is configured with a distributed human-machine interface, which allows operators to perform collaborative operations through multiple screens, thereby achieving more flexible and intuitive control. In addition, the operator station module 400 is also provided with a real-time trend display window, which can display in real time the change trends of key parameters of the distributed thermal power unit simulation system 10, helping operators quickly identify and respond to any abnormalities in the system state. The alarm management console provides centralized management and control functions for system alarms, ensuring that operators can be notified in a timely manner and take corresponding measures when any potential problems occur.

[0073] Optionally, in some embodiments, the engineer station module 500 includes: a control logic development unit, a human-machine interface configuration unit, and an engineering management unit. Among them, the control logic development unit is used to edit the control logic algorithm configuration of the simulator; the human-machine interface configuration unit is used to support the design of monitoring screens; the engineering management unit is used to support the management of control system project resources and configure system parameters.

[0074] Specifically, the engineer station module 500 consists of a control logic development unit, a human-machine interface configuration unit, and an engineering management unit. The control logic development unit supports algorithm configuration, that is, editing and developing the control logic algorithms of the simulator to ensure the efficient operation of the intelligent decision-making and automated control of the distributed thermal power unit simulation system 10. Through this unit, engineers can design complex control strategies to meet various automation requirements. The human-machine interface configuration unit supports the design of monitoring screens, that is, it can provide a visual editing interface, enabling engineers to easily create and customize monitoring screens. The engineering management unit supports the management of control system project resources, that is, engineers can configure the parameters of the distributed thermal power unit simulation system 10 and centrally manage engineering resources such as control logic files, device model parameter libraries, and historical simulation data of different unit models.

[0075] In summary, through the close cooperation of these three units, the engineer station module 500 provides engineers with a comprehensive development and management platform, enabling them to efficiently complete the development of control logic, the design of human-machine interfaces, and the management of engineering projects, thus ensuring the stable operation and continuous optimization of the entire automation system.

[0076] Optionally, in some embodiments, the virtual data processor module 600 includes at least one of a configurable algorithm container and a hardware abstraction layer that adapts to controller protocols of different manufacturers.

[0077] Specifically, the virtual data processor module 600 has a configurable algorithm container, which enables users to load custom control logic according to their needs; in addition, it also includes a hardware abstraction layer that can adapt to controller protocols from different manufacturers, thus ensuring wide compatibility. In addition, the virtual data processor module 600 also has a built-in real-time guarantee mechanism, which ensures the accuracy of the control cycle, thus meeting the high requirements of real-time systems for time sensitivity.

[0078] Optionally, in some embodiments, the model service module 700 includes at least one of a thermal system dynamic model library, a fluid network calculation engine, and a multi-rate co-simulation interface.

[0079] Specifically, the dynamic model library of the thermal system is one of the core parts of the model service module 700. It stores the dynamic behavior models of various thermal systems under different working conditions, which are used to construct the dynamic mathematical models of thermal equipment (such as boilers, steam turbines, etc.) in thermal power units, simulate their physical behaviors and energy conversion processes, and provide important data support for system optimization and fault diagnosis. The fluid network calculation engine is a component in the model service module 700 responsible for handling fluid dynamics calculations. By adopting fluid mechanics algorithms, it realizes the dynamic calculations of parameters such as flow rate, pressure, and temperature of fluid systems (such as steam pipelines, cooling water networks), and supports the high-precision simulation of complex pipe networks. The multi-rate co-simulation interface is used to coordinate the simulation processes of different time scales (such as fast control cycles and slow thermal processes), ensuring data synchronization and calculation consistency among multi-rate models.

[0080] Optionally, in some embodiments, the Web service module 800 is specifically configured to: push real-time data based on a preset network communication protocol; dynamically adjust the remote monitoring interface according to different devices and screen sizes.

[0081] Specifically, the Web service module 800 implements a real-time data push function based on WebSocket technology, which allows for fast and two-way communication between the server and the client, ensuring instant data updates and transmissions. In addition, the Web service module also has an automatic adaptation function for remote monitoring views, which means that regardless of the device used by the user to access, the system can automatically adjust the interface layout and content display to obtain a clear display effect. Finally, the Web service module 800 also supports the secure tunnel transmission protocol, protecting the security of the data transmission process through an encrypted channel, preventing the leakage of sensitive information, and providing a solid guarantee for the data security of users.

[0082] Furthermore, based on the distributed thermal power unit simulation system, Figure 2 is a flowchart of a distributed thermal power unit simulation method according to an embodiment of the present application.

[0086] Step S204: Start the authorization and authentication module, establish a secure session channel (encrypted communication link (such as TLS (Transport Layer Security) / SSL (Secure Sockets Layer) protocol)), read the configuration information (such as system parameters (such as unit capacity), module deployment settings (IP address, port), security authentication parameters (authentication method, permission policy), communication protocol, data format, and hardware resource configuration), and initialize the user permission information of the simulation system. Detect whether the database service module is online. If it is online, record the startup information of the authorization and authentication module (such as the identification information of the authorization and authentication module, network configuration parameters, resource occupancy status, startup timestamp, etc.) into the status storage unit of the database service module, and promptly respond to the data synchronization instruction to update the status information, and establish a secure session channel to provide secure authentication services externally; if it is not online, reject the service and detect the status of the database service module at a fixed period.

[0087] Step S205: Start the operator station module, read the configuration information (such as the network configuration, interface settings, permission parameters, etc. of the operator station module), detect whether the database service module is online. If it is online, record the startup information (IP, port, resource usage, etc.) of the operator station module into the status storage unit of the database service module, and promptly respond to the data synchronization instruction to update the status information, and provide thermal power unit simulation training services to the operator. If it is not online, reject the service and detect the status of the database service module at a fixed period.

[0088] Step S206: Start the engineer station module, read the configuration information (tool configuration, network settings, permissions, etc.), detect whether the database service module is online. If it is online, record the startup information (operating status, IP, initialization parameters, etc.) of the engineer station module into the status storage unit of the database service module, and promptly respond to the data synchronization instruction to update the status information, and provide control logic algorithm configuration and human-machine interaction interface design services to the engineer. If it is not online, reject the service and detect the status of the database service module at a fixed period.

[0089] Step S207: Start the virtual data processor module, read the configuration information (such as algorithm container configuration, control logic parameters, protocol adaptation parameters, etc.), detect whether the database service module is online. If it is online, record the startup information (operating status, IP, port, etc.) of the virtual data processor module into the status storage unit of the database service module, and promptly respond to the data synchronization instruction to update the status information, and at the same time load the simulation algorithm in the DPU to simulate the logical operation of the field control system. If it is not online, reject the service and detect the status of the database service module at a fixed period.

[0090] Step S208: Start the model service module, read the configuration information (module deployment parameters, communication settings, resource allocation, etc.), detect whether the database service module is online. If it is online, record the startup information of the model service module (IP, port, startup time, resource usage, etc.) into the status storage unit of the database service module, and promptly respond to the data synchronization instruction to update the status information. At the same time, load the physical device mathematical model and perform real-time simulation calculations.

At the same time, provide a remote access interface based on the network protocol. If it is not online, reject providing services and detect the status of the database service module at a fixed period.

[0092] Among them, the process of the operator station module accessing the data of the model service module is as follows: First, the operator station module detects whether the database service module is online. If it is online, retrieve the startup record information of the model service module in the database, including the IP address of the server where it runs and the communication port. If it is not online, reject providing services. Second, the operator station module retrieves the startup record information of the authorization and authentication module in the database, including the IP address of the server where it runs and the communication port. If it is not online, reject providing services. Then, according to the IP address and communication port of the authorization and authentication module, the operator station module establishes a TCP (Transmission Control Protocol) / IP (Internet Protocol) communication link with the authorization and authentication module, and reads the current user authorization information in the authorization and authentication module. If the current user has the operation permission, proceed to the next step; otherwise, reject providing services. Finally, according to the IP address and communication port of the model service module, the operator station module establishes a TCP / IP communication link with the model service module, reads the thermal power unit simulation model in the model service module, and provides model simulation services.

[0093] It should be noted that the distributed thermal power unit simulation system proposed in the embodiment of the present application has high flexibility and configurability. Different types of functional modules can be flexibly deployed on one machine or distributed on different machines to meet different performance and reliability requirements.
