Re: OTS Process16 March 2007 at 1:29pmTo achieve a successful outcome with an OTS, it is essential that the dynamic simulator replicates true plant behavior and performance in regards to heat and mass balances under transient conditions (lags and dead time).
The control loops should be identical to those on the existing plant in terms of calibration and valve sizing for controller tuning exercises to be meaningful.
The graphical user interface (GUI) should be identical to that used on the plant control system to ensure operator obtains maximum benefit and is not confused.
A detailed user requirement specification (URS) where the OTS objectives, plant start up, shutdown, feed change, services excursions and failure conditions to be investigated are provided.
The interaction between the instructor and the trainees should be clearly stated and the training session objectives clearly understood. Preparation of this URS should involve all interested parties including plant management and operating personnel.
