A new dynamic simulator for pulp and paper applications has been developed. The simulator is useful for process optimization and operator training, especially when constructing a new paper machine, or rebuilding an existing one, or introducing new employees. The main advantage of the simulator is that the same control system (Distributed Control System source code) and the same displays in the Operator stations are used in the simulator as in the real plant. In this way process operators get very realistic training of various events. Optimization of an existing process line can be done by testing different ways of operation, and then selecting the best way of operation. A suitable rebuild of an existing mill could be found in a similar manner, i.e. by simulating different rebuild possibilities. A DCS functionality checkout can be done before startup of a real mill, since identical DCS code is used in the simulator as in the real mill.
