Simulation system for simulating operation of process plant, has model regeneration unit, which compares indication of actual value with simulated output to develop updated process model for use by simulation routine

摘要

The system has several simulation blocks with a simulation unit that simulates operation process plant using process model to produces a simulated output for a process variable indicating fluid flow, temperature or pressure, associated with portion of process plant. An input accepts an indication of actual value of process variable corresponding to simulated output. A model regeneration unit compares indication of actual value with simulated output to develop an updated process model for use by simulation routine. Independent claims are included for the following: (1) system for simulating operation of process plant; and (2) method for simulating operation process plant.
