Computer-aided designing of automatic process control systems for thermal power stations

The structure of modern microprocessor systems for automated control of technological processes at cogeneration stations is considered. Methods for computer-aided designing of the lower (sensors and actuators) and upper (cabinets of computerized automation equipment) levels of an automated process control system are proposed. The composition of project documents, the structures of a project database and database of a computer-aided design system, and the way they interact with one another in the course of developing the project of an automated process control system are described. Elements of the interface between a design engineer and computer program are shown.
