Abstract

A method and system for automatically generating simulations for a distributed control system is disclosed herein. A programmed process model generator automatically incorporates a variety of process model data from pre-defined model libraries into descriptions of process equipment including control devices to render simulation models of various degrees of fidelity.

1. A computer-implemented method comprising:
providing, by a computing device, a simulation library comprising one or more process simulation models representing operations of components of a process, the simulation library further comprising one or more cause and effect models, the cause and effect models including transfer constants to represent interdependencies between operating parameters of the process components;
integrating, by the computing device, at least one of the cause and effect models into at least one of the process simulation models to automatically create one or more cause and effect simulation models that represent the component operations in accordance with the interdependent operating parameters; and
connecting, by the computing device, outputs of a dynamic process simulation comprising at least one of the cause and effect simulation models to I/O components of a control system in a simulation environment for use in at least one of checking an arrangement of the process components and performing training before bringing the process components online.

2. The method of claim 1 wherein the cause and effect models include time constant parameters representing a lag between cause and effect of two related operating parameters of the process components.

3. The method of claim 1 wherein the cause and effect models are represented by two-dimensional matrixes where a first dimension specifies a cause and a second dimension specifies an effect.

4. The method of claim 1 wherein the one or more process simulation models are generated from a piping and instrumentation diagram representing the arrangement of the process components.

5. The method of claim 1 further comprising:
generating a virtual process control system definition representative of one or more control processors and one or more physical I/O interfaces to the process;
generating process models; and
connecting the process models to the virtual process control system definition.

6. The method of claim 5 further comprising:
parsing I/O block information from the virtual process control system definition;
creating the process simulation models by a rules engine applying a set of rules to each I/O block name; and
configuring and parameterizing the created process simulation models using rules provided by the rules engine.

7. The method of claim 6 further comprising providing a user interface for creating and modifying the set of rules.

8. The method of claim 6 wherein creating the process simulation models further comprises matching, by the rules engine, I/O block information using regular expression syntax to each rule in the set of rules and creating the process simulation models indicated by each rule to which I/O block information is matched.
