X-Window based graphical modeling system for power plant DCS simulation

摘要

By employing Object-Oriented Programming methods, a graphical modeling system for DCS(Distributed Control System) simulation is developed under the environment of Unix system and X-Window in this paper. Some key techniques, such as the save and load of configuration information, the algorithm of drawing analysis and transformation, and the algorithm sequencing of modules, are introduced. And a new way of realizing online configuration is explored. The graphical modeling system has been used in the development of power plant simulator, satisfactory results have been obtained.
