Design of a new IPC-mode chemical process operator-training simulator

The design of an operator-training computer simulator for chemical processes is very important in the process control and simulation area. In this paper, an operator-training simulator is developed for a small-scale fine chemical production process using an IPC (industrial personal computer and intelligent process controller) simulation mode and a typical SCADA (supervisory control and data acquisition) configuration software as the GUI (graphical user interface) platform. The dynamic behavior of the process is modelled by the dynamic compensation modelling method. The overall simulation software package is successfully integrated by the designed DLL (dynamic link library) function program, which is used to link the dynamic model calculation program to the simulation GUI through the database of the SCADA configuration software. The simulator is demonstrated to have good performance in chemical process operator-training practice.
