These options are all available on the Contingency Analysis dialog under the Contingency Options tab under the Miscellaneous grouping.
Always save results with the contingency list when you save it to a file
If this option is checked, the violation results for each contingency will also be stored in an auxiliary file when the list of contingencies is saved to an auxiliary file. This allows for recovering the results of a contingency analysis run for a case, without reloading and re-running all the contingencies saved in the file.
Save contingency analysis definitions/results in the case PWB file
If this option is checked, the contingency definitions and any processed results will be saved with the load flow case in the PWB file when you save the case.
Setting Reference Case when Contingency Analysis is Opened
These options determine how the reference case for the contingency analysis is treated each time you open the contingency analysis dialog. The reference state is initially defined as the power system state that exists when the contingency analysis is run for the first time for a given power flow case during a Simulator session. The exception to this is that it might be set to the current system state when the dialog is open, prior to running any analysis, if the option that is described below is specified to set the reference case each time that the dialog is opened. (See Contingency Case References - Defining the Reference State for more information.) The choices are to how this option can be set are:
Always set reference case to the current case
This option will always assume that any changes you have made to the load flow case since the contingency analysis was last opened should be applied and will store the current state of the load flow as the new reference state for the contingency analysis.
Always use the existing contingency analysis reference case
This option will assume that if the contingency reference state has already been set, just continue to use that. This means that any changes that have been made to the load flow case since the initial setting of the reference case will be lost, as the contingency analysis tool will reset the load flow state to the stored reference state.
Prompt for which reference case to use (the current case or the pre-existing reference case) whenever the Contingency Analysis Form is opened
When this option is checked, you will always be prompted when you open the contingency analysis if the reference case has already been set. You will then have the option to choose from one of the two previous settings, to either set the reference state to the current case or use the existing reference case currently stored with the contingency analysis tool.
Contingency Action Description in What Occurred
This provides options for the naming convention used when identifying the actions that occurred during the contingency. This affects how the Actions are specified in the What Occurred information. This option needs to be changed BEFORE the contingency analysis is run. If it is changed AFTER, no changes are made to the action identifier.
