Model Result Override

 

Added in Version 20

Model Result Overrides allow the direct specification of the result of a Model Condition, Model Filter, or Model Expression. When a Model Result Override is active, the logic for the object it is overriding is ignored. This is useful with EMS cases where real-time measurements might determine RAS arming. The logic of the overridden object can remain defined and used when necessary, but a direct replacement of the result is very simple without having to redefine contingency action and remedial action model criteria.

Model Result Overrides can be found in the Model Explorer under Case Information and Auxiliary > Model Result Overrides or on the Contingency Analysis dialog on the Options tab in the Remedial Action Definitions grouping.

 

Model Result Override Display

The Model Result Override Display is a type of Case Information display and has the abilities common to this type of display. To create a new Model Result Override, select Insert from the local menu. This will open a dialog for entering the Name of the model result override. All other parameters for the model result override can be specified in the fields in the display.

The following fields are shown by default on the display:

Name

Unique identifier for the model result override.

Model Object

This is the object type and name of the Model Condition, Model Filter, or Model Expression to which the override is applied. To specify the model object, select this field and the dialog button will appear to the far right of the cell. Click the dialog button to open a dialog that contains an object chooser which allows easy selection of the model object. Double clicking on this field will also open the model object selection dialog.

Result Value

This field will be non-blank if the Model Object chosen is a Model Expression. This specifies the value result of the Model Expression that is being overridden.

Result Boolean

This field will be non-blank if the Model Object chosen is a Model Condition or Model Filter. This specifies the boolean (YES/NO) result of the Model Condition or Model Filter that is being overridden.

Enabled

Set this field to YES to apply the override and use the result specified in either the Result Value or Result Boolean field for the chosen Model Object and ignore the logic defined with the object itself.

 

Model Object Overridden Indicators

Model Conditions, Model Filters, and Model Expressions all have an Overridden field available in their list of available fields. This field indicates if the object is being overridden by an enabled Model Result Override. If this field is YES, the result that is displayed for the object is the result, either the Result Value or Result Boolean depending on the object type, that is specified with the Model Result Override.

The object dialogs for these objects also have indicators in which parts of the dialogs will be highlighted in yellow and special messages appear if the object is being overridden by an enabled Model Result Override.
