Abstract

A method for monitoring operation behavior of a component of an industrial plant is provided. Parameter identifiers of operation parameters of the industrial plant are read from an element of a control system of the plant. Some of these parameter identifiers are selected and the selected parameter identifiers are forwarded to an element of the control system. Further, a time of a specified operation of the component is defined and behavior of the selected parameters of the component in the defined time is used as guide model for monitoring selected parameters of the component during component operation.

Claims

1. A method for monitoring operation behaviour of a component of an industrial plant, the method comprising:

reading out parameter identifiers of operation parameters of the industrial plant from an element of a control system of the plant;

transferring the read parameter identifiers into an editable form;

selecting some of these parameter identifiers in the editable form;

generating a machine readable description containing the selected parameter identifiers together with commands for the control system to generate a structure of control system modeling elements representing the operation parameters of the selected parameter identifiers;

forwarding the machine readable description to an element of the control system;

instantiating elements and connections according to the machine readable description and generating a structure of control system modeling elements representing the operation parameters of the selected parameter identifiers by the element of the control system;

generating a guide model for monitoring the component using the structure by the element of the control system;

defining a time of a specified operation of the component; and

using a behaviour of the operation parameters of the selected parameter identifiers at the defined time training the guide model for monitoring selected parameters during component operation by the element of the control system.

2. The method according to claim 1, wherein the selecting of parameter identifiers is a filtering process with a filter operator.

3. The method according to claim 1, wherein the elements each are state estimators for generating expectancy values for the respective parameter.

4. The method according to claim 1, wherein the structure comprises a model of a part of the control system.

5. The method according to claim 1, wherein the specified operation of the component is a normal operation of the component.

6. The method according to claim 1, wherein the time of a specified operation of the component is a time period.

7. The method according to claim 1, further comprising:

monitoring a deviation of values of the selected parameters of the component from values of the selected parameters of the guide model during component operation.

8. The method according to claim 1, wherein the machine readable description is of a XML-format.
