Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automatic control of energy stations, and particularly relates to an energy station energy optimization scheduling control system for comprehensive energy services. BACKGROUND

[0002] Energy is an important material basis and driving force for the progress of human civilization, and is related to the national economy and people's livelihood and national security. Accelerating the construction of a modern energy system is an inherent requirement for ensuring national energy security and striving to achieve the carbon peak and carbon neutralization on schedule, and is also an important support for promoting high-quality economic and social development. Building a comprehensive energy system is conducive to promoting energy transformation and helping to achieve the double- carbon control target. A comprehensive energy station is a comprehensive energy system distributed at the user side, which realizes energy cascade utilization and efficient and low-carbon utilization to directly meet the needs of users, effectively improving the safety and flexibility of energy utilization. The energy supply side is centered on multi-energy complementation, cascade utilization and comprehensive supply.

[0003] A comprehensive energy station is the core of a regional comprehensive energy system, and an N-station-in-one comprehensive energy station is a unified construction, management and operation of an energy supply station, an energy service station, an energy storage station, an electric vehicle charging station, a data center, a 5G base station and the like, realizing multi-station distributed logical fusion, structural complementary, data horizontal penetration, meeting different needs of energy users, and forming a new industry and mode of comprehensive energy services.

[0004] A comprehensive energy station has multiple energy forms, multiple energy conversion links, multiple operation modes and diverse user energy demand. A comprehensive energy station contains numerous devices and systems, such as gas turbine units, photovoltaic, wind turbine units, waste heat boilers, electric-to-gas equipment, absorption chillers, water chillers, electric boilers, batteries, heat storage tanks, ice storage, heat networks, heat pumps, plate heat exchangers, boiler makeup water plants, pressure regulating stations, mechanical towers and the like. The operation laws and control strategies between individual systems and devices are quite different. Traditionally, PLC, DDC, single-chip microcomputers and embedded development boards are generally used to control each system and device, but there are certain difficulties and challenges in the large-scale engineering application of high-level energy optimization scheduling and interconnected collaborative control of comprehensive energy stations.

[0005] The integrated energy station system is always in a dynamic changing environment under multi / strong disturbance, the internal links of the system are seriously coupled and show obvious multi-heterogeneous nonlinear characteristics. The uncertainty of load demand, the coupling of cold / heat / electricity / gas, and the multi-time scale complementary characteristics among multiple energies make the energy management optimization scheduling and self-control strategy of the integrated energy station very complex, and advanced process control algorithms and artificial intelligence algorithms are generally used for calculation and solution. On the one hand, due to the limitations of the limited computing and storage resources of PLC / DDC, it is difficult to meet the real-time process control requirements of advanced process control algorithms, artificial intelligence algorithms, and complex energy management and self-control strategies, and the control mode based on traditional PLC / DDC cannot realize large-scale engineering application of optimization scheduling algorithms. On the other hand, the energy management, optimization scheduling and self-control strategy formulated and run by traditional PLC / DDC for individual equipment is not designed from the perspective of global optimization of the integrated energy station, and cannot control the operation of the equipment from the perspective of global system factors, and cannot guarantee that the energy station is in an optimal operating state in real time.

[0006] In addition, the integrated energy station has typical characteristics such as complex process, multi-process flow coupling and association, and complex production conditions require that the automatic control system be highly matched with the production rhythm, and that energy and production data be deeply integrated and cooperated to solve the problems of energy flow changes and system disturbances caused by multi-source energy integration, conversion and consumption. However, in the real-time operation of the integrated energy station, when facing complex coupled process flow and abnormal conditions, operation maintenance and management are highly dependent on human experience, and production operation and management decisions are mostly dependent on the knowledge reserve and cognitive level of the post personnel, which is prone to misoperation, omission, and even production safety accidents. This seriously restricts the intensification, refinement and efficiency of the production operation of the integrated energy station, and hinders the green and low-carbon development transformation of the industry. At the same time, when relying mainly on human experience, the operation and maintenance level and performance of each energy station will differ greatly, and advanced expert experience, industry solutions and excellent energy station control strategies are difficult to be fixed, and thus it is difficult to be shared and reused in the same type of project, which hinders the improvement of the efficiency of the implementation of the integrated energy station project and the large-scale engineering application of advanced experience. SUMMARY

[0007] The purpose of the present application is to provide an energy station energy optimization scheduling control system for integrated energy services, to solve the problem that advanced process control algorithms, artificial intelligence algorithms, and complex energy management and self-control strategies in the prior art cannot be implemented in engineering applications on traditional PLC / DDC and other equipment.

[0008] In order to achieve the above purpose, the solution of the present application is:

[0018] The function blocks are connected by the contact line, the function block contact line can only connect one function block output pin and one function block input pin, and the data types of the input pin and the output pin are consistent.

BRIEF DESCRIPTION OF DRAWINGS

[0025] Figure 1 is a schematic block diagram of the connection structure of each module in the present application;

[0026] Figure 2 is a schematic block diagram of the modular functional block structure in the present application. DETAILED DESCRIPTION

[0027] The technical solutions and beneficial effects of the present application will be described in detail below with reference to the accompanying drawings.

[0028] The application discloses an energy station energy optimization scheduling control system for comprehensive energy service, and the whole development environment runs on a PC operating system to provide a development, writing and debugging integrated environment for users. Figure 1

[0029] The engineering management module performs project creation and management, file management, user permission management and system parameter setting, and the functions are as follows.

[0030] Project creation and management: a user can create a new control project and manage an existing project, including project opening, closing, saving, saving as and the like. For example, when starting a new energy station automatic control project, the user first creates a new project file to store relevant programs and configuration information.

[0031] File management: responsible for managing various files involved in the project, such as configuration files, configuration files, data files and the like. It can realize functions such as file import, export, backup and recovery, and ensure the safety and maintainability of the project file.

[0032] User permission management: in order to ensure the safety and reliability of the system, the software provides user permission management function, sets different operation permissions for different users, and the user roles are administrator, engineer and operator. The operations and accessed resources of users with different permissions are different, and the user operation permissions include viewing permission, read-write permission and management permission, so as to prevent unauthorized operation and access.

[0033] System parameter setting: allows users to set various parameters of the system, such as algorithm calculation period, communication parameter, data acquisition period, alarm threshold, interface display parameter and the like. By reasonably setting the system parameters, different control requirements and application scenarios can be met.

[0034] The viewing permission is that the user can only view configuration pictures, real-time data, historical data and the like, and cannot perform any modification operation. For example, in a factory monitoring system, ordinary visitors can view the running state of the production line through the configuration software, but cannot change the device parameters and the like. This permission helps to protect the integrity of system data, and can also meet the information acquisition requirements of some personnel.

[0035] The read-write permission is that the user is allowed to read and write some or all configuration elements. This includes modifying, increasing or adjusting function blocks, device parameter setting, such as changing the set temperature of a temperature controller, adjusting the speed setting value of a motor and the like. For engineers or operators on the scene, they need this permission to optimize and control the device according to the actual production situation.​

[0036] The management permission is user account management, which can create new users, delete users, modify user permissions, and manage the overall configuration of the system, such as adding or deleting data acquisition channels, setting communication parameters, ensuring normal communication between the control strategy configuration software and the runtime control module, and normal communication between the database and external sensors and the system. At the same time, the running parameters of the software can be optimized, such as setting the calculation period, alarm threshold, etc. In a complex industrial automation system, the system administrator can assign different permissions to different personnel according to their responsibilities to ensure the safety and orderliness of the system.

[0037] The control strategy editing module provides a standard programming graphical interface environment for users, based on the graphical view framework, and uses a modular functional block programming method. Users can configure control logic according to control schemes and process technology. The control strategy editing module generates control strategy configuration files and configuration files for the runtime control module.

[0038] In the graphical interface environment of the control strategy editing, flexible interface layout and design functions are provided, and users can arrange, combine, align, and scale functional block graphical elements according to actual needs to design a control interface that meets operational habits and aesthetic requirements. Sampling graphical visual technology is used to manage and control all modular functional block graphical items. Based on the graphical view framework, precise double-precision interaction functions are provided for modular functional block graphical items, supporting event propagation to each graphical item, supporting mouse press, move, release, and double-click, mouse hover, mouse wheel, scaling and rotation, drag and drop, grouping, collision detection, keyboard input focus, and keyboard events.

[0039] Buffered graphics are used to speed up rendering. When a functional block graphical item is first drawn, it is mapped to the cache. Then, for each subsequent exposure, the cache is reused. When a graphical item needs to be redrawn, the cached graphical item is used. For example, after switching to another function page and returning to the original function page, the above buffered graphics mechanism can speed up the rendering of functional block graphical items and shorten the presentation time of the overall function page interface.

[0040] As shown in Figure 2 Each modular functional block includes an English name, a Chinese description, an output measurement point number, an input pin, an output pin, an intermediate parameter, a functional block serial number, and a functional block calculation level.

[0041] Combining the production process of the comprehensive energy system industry and a large amount of engineering implementation experience, expert experience and optimized industry solutions are packaged and solidified into general intelligent modules, which can be shared and reused in multiple subfields and similar projects. Users do not need professional knowledge and programming experience to complete the design and debugging of engineering control logic.

[0042] The function block serial number is numbered from small to large according to the order of adding to the function page (algorithm page) from the algorithm library, and the function block serial number is not allowed to be repeated.

[0043] The function block calculation level is set by the following method, the calculation level of the function block in the first drag-in function page is defined as 1, in each function page, the function block calculation level of the next level function block is greater than the function block calculation level of the previous level function block by 1, when the next level function block is connected with multiple previous level function blocks through the liaison line, the function block calculation level of the next level function block is the maximum value of the function block calculation level of the multiple previous level function blocks plus 1.

[0044] The self-control logic design is carried out by adopting the paging idea, the programming graphical interface environment is used to edit the function block in the form of function page, each function page has its own function page serial number, the function page serial number is arranged in increasing order starting from 1, and is not allowed to be repeated. Any modular function block must be deployed on the function page.

[0045] In the configuration process, each function page saves a self-control strategy configuration file automatically generated after. Preferably, the self-control strategy configuration file is generated based on the SQLite embedded database, and the SQLite database is stored in a single self-control strategy configuration file.

[0046] The function blocks are connected by the liaison line, the function block liaison line can only connect one function block output pin and one function block input pin, and the data types of the input pin and the output pin should be consistent. The starting point is defined as the input pin coordinate point, and the ending point is defined as the output pin coordinate point, and the drawing method of the polyline between the starting point and the ending point is as follows: when the starting point and the ending point are on the same horizontal line or vertical line, the polyline between the starting point and the ending point is a straight line; otherwise, the polyline between the starting point and the ending point is a polyline with 2 breakpoints, the vertical coordinate of the first breakpoint is the vertical coordinate of the starting point, the horizontal coordinate of the first breakpoint is the average of the horizontal coordinates of the starting point and the ending point, the vertical coordinate of the second breakpoint is the average of the vertical coordinates of the starting point and the ending point, and the vertical coordinate of the second breakpoint is the horizontal coordinate of the ending point. When any one of the function blocks connected by the liaison line is dragged, the liaison line is immediately redrawn according to the above method.

[0047] A plurality of modular function blocks are designed to form a general algorithm library, and the function blocks are designed and developed by fully referring to the device performance, system characteristics, process control technology, multi-process flow coupling and correlation characteristics of the comprehensive energy station, and industry experience.

[0048] Further, the user can design and develop a modular functional block according to the specific requirements of the project to form a special algorithm library, that is, allow the user to write script code to achieve more complex logic control and function extension. The user can write specific program logic according to his own needs to enhance the functionality and interactivity of the self-control logic design module, such as a special algorithm strategy for the electromagnetic torque and variable pitch joint control of a certain permanent magnet direct drive wind turbine, or triggering certain operations or performing specific calculations under certain conditions.

[0049] The combination of the general algorithm library and the special algorithm library improves the flexibility and scalability of the energy optimization scheduling and interconnected collaborative automatic control logic design method of the comprehensive energy station.

[0050] The runtime control module automatically parses the self-control strategy configuration file and the configuration file generated by the self-control strategy editing module, loads the configured strategy target system into the computer memory and performs the predetermined various data calculation and data processing tasks, and at the same time completes the data exchange with the real-time database, realizes the logic control and algorithm operation of the comprehensive energy station process and energy management optimization scheduling process.

[0051] The runtime control module performs cyclic calculation according to the calculation period set by the engineering management module, and in each calculation clock period, the calculation is performed in the order of the function page number from small to large. For multiple working condition blocks in the same function page, the calculation is performed in the order of the function block calculation level from small to large. For algorithm blocks of the same function block calculation level, the calculation is performed in the order of the function block serial number from small to large.

[0052] When the runtime control module parses the function blocks one by one, it first judges the input pin data type of each function block. There are three types of input pin data types, namely constant, output value of other function blocks and measured point value of the real-time database. When the input pin is configured as a constant in the self-control strategy programming graphical interface, the input data is a constant. When the input pin is configured as a measured point in the self-control strategy programming graphical interface, the input data is the measured point value of the real-time database. When the input of the function block is connected to the previous function block through a tie line, the input pin in the self-control strategy programming graphical interface is automatically configured as the output name of the previous function block. According to the type of the input pin, the runtime control module obtains the corresponding input value from the parsed data in the self-control strategy configuration file loaded into the computer memory, the calculated output value of other function blocks stored in the memory and the real-time value of the real-time database measured point obtained by calling the API. After calling the function block module calculation, the output value of the function block is obtained.

[0053] Preferably, the runtime control module supports the non-interference updating operation of the automatic control strategy editing module, that is, without stopping the entire runtime control module, the automatic control strategy configuration file generated by the automatic control strategy editing module can be automatically parsed and loaded in the running periodical calculation task in real time, thereby ensuring that the running of the control system is not disturbed, the production process can continuously and stably proceed, and unexpected shutdown, error action or data loss and the like do not occur due to program updating.

[0054] The unified data support module includes a real-time database and a communication protocol stack manager. The communication protocol stack manager completes real-time data acquisition of multiple subsystems of the integrated energy station based on an industrial protocol, and stores the data in the real-time database, realizes integration of multi-source heterogeneous data, and simultaneously serves as a bridge for data interaction of the logical configuration application module and the runtime control module, and provides data read-write services for the two.

[0055] The unified data support module supports automatic creation of measurement points generated by the automatic control logic design module in the real-time database. These data include input variables, output variables, intermediate variables and parameter variables. These data include values of input signals, output signals, intermediate variables, timers and counters. The data stored in the real-time database are supported to be managed and queried, including data adding, deleting, modifying, querying, statistics and the like.

[0056] The communication protocol stack manager configures and manages various hardware devices, sensors and systems connected to the real-time database, including selection of slave sensor models and setting of communication parameters. For example, when collecting data of an electric meter supporting a Modbus RTU protocol, corresponding device parameters such as slave station address, baud rate, data bit, stop bit, check bit, timeout time, retry number and byte sequence need to be set, so that the system can correctly communicate and interact with these devices.

[0057] Meanwhile, data communication and sharing with other systems or devices are supported, such as data exchange with a host computer monitoring system, an MES system and a third-party monitoring system. Through data communication and sharing, integration and interconnection collaborative work of the entire automatic control system can be realized.

[0058] The entire development environment runs on a PC operating system, and provides an integrated environment for development, writing and debugging for users. The database adopts a master-slave dual-computer hot-standby redundant configuration mode to improve the high availability of the system.

[0059] The fieldbus and industrial communication protocols supported by the communication protocol stack manager include, but are not limited to, EtherCAT, EtherNet, Profibus, CANOpen, CANBus, DeviceNet, BACNet, IEC104, MQTT, Modbus, OPC. The external data forwarding protocols and manners of the unified data support module include, but are not limited to, WebAPI, WebSocket, API, SDK, WebsService, MQTT, Modbus.
