Application of ABB AC800F control platform in 1 million tons/year coking project1 IntroductionA limited liability company in Qinghai invested in a new coking project with an annual capacity of 1 million tons. Since it is located on a plateau, in order to increase productivity and ensure the continued safe and stable operation of the system, the company selected the widely used ABB AC800F system. ABB AC800F dcs system is a control platform based on Industrial IT (Industrial IT). It has a high level of industrial automation. It adopts open integrated controllers, the latest technologies and standards, and has information integration, high engineering efficiency, and advanced scalable solutions. solutions, open communication, plug-and-play and other features. It also has an open integrated controller and a global data management system. It is the world”s leading automation control system that integrates the advantages of DCS and PLC .2. Project introductionThe company is a comprehensive large-scale privately owned enterprise group integrating mining, mineral processing, metallurgy, and coal chemical industries. In order to adapt to the harsh environment, taking into account the informatization and automation of modern enterprises, and the needs of sustainable development, the latest technology was applied in the newly built 1 million tons/year coking project and the ABB AC800F control system was selected, which has Industrial IT Control platform, based on fieldbus, improves the company”s informatization and automation level. The I/O module uses the S800 series as a distributed process station to make work easier.3. Characteristics of AC800F controllerAC800F controller is a world-leading automation control system launched by ABB. It integrates the advantages of DCS and PLC and supports a variety of international fieldbus standards. It not only has the complex analog loop adjustment capabilities of dcs, friendly human-machine interface (HMI ) and convenient engineering software, but also has high-speed logic and sequence control performance comparable to high-end PLC indicators. The system can be connected to both conventional I/O and various fieldbus devices such as Profibus, FF, CAN Modbus, etc. The system has a high degree of flexibility and excellent scalability. It can handle whether it is the control of small production devices or ultra-large-scale integrated control of the entire factory, or even cross-factory management and control applications. After the system is upgraded to version V7.1 or above, the system capacity can reach infinite points (more than 1 million I/Os). If the system needs to be expanded in the future, I/O or fieldbus instruments can be added directly on this basis. , conducive to future development. The AC800F system upgrades the ABB control system from the traditional process automation control concept to a factory production management system based on factory-wide informationization. Its purpose is to provide users at all levels with what they need at the most appropriate time and from the most appropriate angle. The most accurate and detailed information enables them to run factory production efficiently. The system can be divided into operation management level and process control level. The operation management level includes operation station OS, engineering station ES, and gateway GS.At the operation management level, it can not only realize traditional control system monitoring and operation functions (predefined and free-form dynamic screen display, trend display, pop-up alarm and operation guidance information, report printing, hardware diagnosis, etc.), but also complete recipe management and Data exchange and other management functions. The process control level can consist of one or several process stations, each including AC800F and expansion I/O S800 units.Both the process station CPU and I/O units can be configured as redundant or non-redundant systems. The system has various I/O modules that can be connected to various process signals on site.Compared with other distributed control systems, combined with the development history of the AC800F control system, we summarize the new technologies of the system as follows:(1) Open fieldbus technologyAlthough this project does not use fieldbus field instruments for the time being, in order to facilitate the future development of users, we have reserved a bus hardware interface . In terms of software, the Profibus template of ABB AC800F controller supports DPV1. Compared with the pure DP standard module, the standard module has increased instrument configuration capabilities. In this way, there is no need to install special configuration software for various instruments. Only the equipment parameter file (GSD file) of each instrument is imported, and it can be realized in The function of programming and configuring the parameters of all PA standard instruments under the unified system programming software effectively saves software costs and improves the efficiency of engineering configuration.
