1. Baikalai APROL (DCS) System 1.1 APROL Historical Review
The Baikalai APROL process control system is a highly integrated, integrated, modular, and modern concept process control system based on the LINUX system platform.
Since its launch in 1984, APROL has a 20 year history of application, covering process control industries such as petrochemicals, metallurgy, pharmaceuticals, food, and water treatment.
1.2 APROL 3. xx New Features: With the increasing demands of production processes on the reliability, computing power, scalability, openness, operation, and monitoring level of control systems, as well as the rapid development of industrial automation process control theory and computer technology, APROL has also made significant improvements in performance and functionality. Last year, the APROL 3. XX version was launched, which was managed and parallelized in the original version, On the basis of object-oriented super macros and other features, many new features have been added 1.2.1 Immediate check of input validity. The prompt that pops up immediately informs the configuration engineer that an error has occurred. For example, if you type in the IP address 192.168.0.325, APROL will tell you that the IP address is incorrect. Please re-enter it. If you don’t know how to input, click the help button next to it to view the input rules and examples. 1.2.2 Detailed Icon Information APROL uses fixed icons to distinguish different types of components. You can categorize and list them by icon type, and a large number of charts are beneficial for managing project components. When opening the project directory, various components are clear at a glance.
1.2.3 Offline configuration function: Some major project changes need to be simulated in the office before on-site debugging, which requires the use of offline configuration function If it is an improvement to the existing control strategy on site, first export and lock it on site, then import it on the company’s PC, improve and test it, and then import and replace it on site 1.2.4 Screen enlargement and reduction function: The monitoring screen can be designed according to the size of a 10 * 10 display screen. When monitoring, it can be scaled like AUTOCAD, or navigated to a local display screen, or zoomed in and monitored according to the required ratio. 1.2.5 The configuration modification log engineer modifies the control logic, monitors the screen, compiles a certain component, and downloads a controller program. The system will record all changes, including: Who is the operator? When did it happen? What location (which computer)? What did you do? In this way, problems can be quickly identified. 1.2.6 Flexible combination of 32-bit and 64 bit architectures. Due to LINUX’s support for 32-bit and 64 bit systems, APROL based on SUSE LINUX can easily achieve a 64 bit redundant system architecture and can flexibly combine various architecture PCs. 64 Bit E R/64 Bit O G 64 Bit E R/32 Bit O G 32BitE R/32BitO G Description: E – Engineering Station R – Server Station (Runtime) O – Operator Station G – Gateway Station 1.2.7 The new help search engine allows for faster access to detailed technical details such as APROL product and technical information, user guides, and operation processes.
1.2.8 When upgrading the controller operating system update project, it may be necessary to upgrade the controller operating system. Through the operating system management window, engineers can import new operating system software packages to achieve local project upgrades. 1.2.9 Function block supports initialization and exit code. Any function block supports initialization and exit code. In this section of code, engineers can perform local initialization and exit processing. Local initialization facilitates object-oriented design style.
1.2.10 Enhancement of Display Editor function: Screen editing adds practical functions such as gradient colors, component combination/splitting, alignment, etc. Make the project configuration more diverse and the graphics cleaner. 1.2.11 Variable number of input/output pins function. For the same type of function block, if the number of pins is not fixed and the pin attributes are the same, it is now classified as a single function block. The number of pins in the function block can be increased by dragging the mouse to enlarge the function block. Typical examples include Boolean operations such as AND, OR, and arithmetic operations such as addition, subtraction, multiplication, and division 1.2.12 Controller load online evaluation function APROL provides a tool to evaluate the load of the controller in real time. The load evaluation is real-time online and can also be analyzed using offline tools. 1.2.13 All components support UNICODE APROL and UNICODE. Regardless of the operating environment or configuration environment, the interface for configuration, alarm, report, monitoring, and other operations can be switched to any language. Even OPC interfaces can provide UNICODE for easy access to different SIS systems. 1.2.14 Support for VM_ WARE Dongle If a user uses VM_ WARE to run APROL, APROL provides support for VM_ WARE’s software dog driver. The software dog is divided into parallel port mode and USB mode, making it convenient for customers to choose flexibly. 1.2.15 Redundancy adds controller power redundancy, controller CPU redundancy, and a safety system that supports SIL3 on top of the original server’s software and hardware redundancy and process bus redundancy.
2. The application of APROL in Shandong Danxian Biopower Plant APROL has been applied in process control industries such as petrochemicals, metallurgy, pharmaceuticals, food, water treatment, etc. The petrochemical industry has been used by European OMV companies for a long time, the metallurgical industry has been transformed into continuous casting and rolling online by European Aogang Union, and the pharmaceutical industry has had more than a decade of cooperation between German Merck Group and APROL, In the food industry, APROL has been applied in over 70 sugar factories in Ukraine for environmental monitoring along the Qinghai Tibet Line in China, supporting sulfur for 2 * 300000 kilowatt units in Yueyang Power Plant, and integrating the main and auxiliary control of a single county biological power plant with an integrated DCS system. Below is a brief introduction to the integrated main and auxiliary control DCS system of a single county biological power plant. 2.1 Project Introduction: The Guoneng Danxian Biopower Plant is China’s first demonstration project for biomass power generation. By introducing Danish biomass power generation technology, a straw burning power generation project is implemented. The construction scale of the project is a 130MW single stage condensing steam turbine generator unit, equipped with a 130t/h biomass dedicated grate high-temperature and high-pressure boiler, which consumes 150000 to 200000 tons of agricultural and forestry waste annually; Every year, 160 million kilowatt hours of valuable green electricity can be generated. While generating green electricity, it can also reduce carbon dioxide emissions by 100000 tons annually, generating over 40 million yuan in income for farmers and creating over 1000 job opportunities. It has good economic, social, and ecological benefits. 2.2 APROL control range: The DCS system control range of Guoneng Shan County Biopower Plant includes boiler, turbine main control, and auxiliary control systems such as chemical water, fuel transportation, fuel oil transportation, electrical, and HVAC. APROL provides an integrated solution for primary and secondary control. The entire system consists of 7 operation stations, 1 engineer station, 5 pairs of DPUs, and I/O scale>3000
