(1) 结合工艺及用户意见确定控制系统控制范围,分布式控制系统基本构成方案和主要控制、管理功能。
(2) 明确三电专业分工,对三电专业各自应完成的控制及管理功能进行划分。Determination stage of control system equipment level
It mainly includes:
3.1.1 Determine the design principle of automatic control system
Generally, the design shall be carried out based on the principles of mature technology, advanced equipment, strong applicability and high reliability.
3.1.2 Determine the basic composition of the distributed control system
The distributed control system is mainly composed of control station unit, operation display station unit and data communication bus. Each station unit is connected by the data communication bus to form the control system, and communicates with each other through the data communication bus to realize the data sharing within the system.
3.1.3 Determine the application function level of the automatic control system, and propose the basic requirements for system hardware and software at each application function level
Field detection, transmission level and basic automation level are necessary when dividing application function levels; As for the process monitoring level and information management level, the choice should be made according to the capital situation of the project and the production management level of users.
3.1.4 Propose the reasonable control range and main control and management functions of the automatic control system
Generally, the main process system of blast furnace production should be included in the control scope.
3.1.5 Recommend several typical distributed control system composition schemes
The distributed control system applied to the automatic control of blast furnace is generally divided into two categories according to the different emphasis on the electrical logic sequence control function and the continuous regulation control function of the instrument: one is the full DCS control system whose electrical logic sequence control function and the continuous regulation control function of the instrument are controlled by the same type of controller, such as the OVATION control system of Westinghouse, PCS7 control system of Siemens, Germany; The other is the "PLC+DCS" control system where the electrical logic sequential control function and the instrument continuous regulation control function are controlled by different types of controllers, such as the Total Plant control system composed of the instrument continuous regulation controller HPM of Honeywell and the electrical logic sequential control PLC of GE, The control system consists of the instrument continuous regulation controller FCS of Yokogawa Corporation of Japan and the electrical logic sequence controller CP23500H of Yaskawa Corporation of Japan.
3.1.6 Put forward opinions on domestic and foreign equipment delivery.
3.1.7 Estimate the investment of automatic control system.
3.2 Integrated evaluation stage of distributed control system
The following aspects are mainly used to comprehensively evaluate and compare several system composition schemes recognized by users, and select the control systems that are excellent in technical performance, use performance, reliability, etc.
