Research on Visual Modeling and Simulation Method for Operational Flowsheets-oriented CANDU Control Systems

Abstract

To flexibly model and accurately simulate CANDU control systems that are described by variety of operational flowsheets, a general visual modeling and simulation method has been researched, in which discrete-similarity algorithm, database and visually graphical modeling technologies are employed. And Parallel Virtual Machine (PVM) is adopted for interface to stand-alone simulation software of controlled objects. Test cases demonstrate that the presented method is effective and reliable, and the modeling and simulation program based on such method is generally applicable for all kinds of control systems in CANDU-type plants.
