Dynamics mode results for the U3 example simulation

The objective of Dynamic mode for this simulation is to study the process control system behavior for upset conditions. To view the results, perform the following steps.

1. Open the HeaderPressures trend.

2. Run the STGA Trip Scenario.

   

The Dynamics worksheet in the U3 – Refinery Steam Distribution.xlsx file provides the same results.

These results show that the pressure control system returned the pressure back to the required set points. However, there was a very high peak in the header pressure for the high pressure line and a low peak in the header pressure for the medium pressure line, which may require additional improvements to the control strategy.
