| To be competitive the pulp and paper industry is taking advantage of advancing technology and using centralized, computer based distributed control systems. While these systems do have the potential to increase productivity, the control systems themselves become another complex part of the overall process that must be mastered.; This work describes five projects involving the use of dynamic models to provide training both in the use of DCS equipment and in the behavior of real processes. There are two steps in accomplishing this goal. (1) Computer code representing the process dynamically must be generated, and (2) that code must be interfaced to the distributed control system on which the training is to take place. Most of the simulation work involved modifying and expanding GEMS, a simulation program already in wide use in the industry. The modeling techniques used and the interfaces created for four different control systems are described. |
