Simulator’s contingency analysis tools can be accessed only from Run Mode. To access this dialog go to the Tools ribbon tab, and choose Contingency Analysis from the Run Mode ribbon group. This will open the Contingency Analysis dialog.
Each tab of the contingency analysis dialog covers a particular aspect of the analysis.
The Contingencies tab is used primarily to manage the contingency list and to learn basic information regarding each contingency and the violations that it causes.
The Options tab contains a panel on the left which provides access to all the options for contingency analysis. The tab enables you to dictate various parameters for the analysis that govern such things as how violations are flagged in both the Base Case and for contingency conditions and what information should be included in the contingency report. It also provides access to more complex contingency definitions and as well as Distributed Computing options.
The Results tab contains a panel on the left which provides access to look through the results of the contingency analysis. It includes the ability to View Result by Element as well as by contingency. Other convenient summaries of contingency analysis results are also available as well as the ability to write results to a Text File.
The Load button will allow the opening of any of the file formats defined in the Loading Contingencies from a File topic.
The Save button will allow the saving of contingency definitions and supporting information. The file formats that are allowed are:
- Simulator Auxiliary File Format (*.aux)
- Simulator Version 5-7 Contingency File Format (*.ctg) (see the old users manual, or contact PowerWorld Corporation)
- PTI PSS/E-formatted Contingency Files (*.con)
- WECC Contingency and RAS File (*.aux)
The Auto Insert button will open the Auto Insertion of Contingency Records dialog.
The Other > button will open a menu containing various contingency related options.
The Start Run button will start the contingency analysis. Additional buttons will appear after the run has started including: Pause Run, Abort and Continue. For more description of how to perform a contingency analysis simulation and what these buttons do see Running the Contingency Analysis.

When the contingency analysis dialog is open and choosing to save a case, checks are done to ensure that the user does not accidentally save a post-contingency system state. If the contingency reference state exists and at least one system device status in the present system is different than the status in the contingency reference state, a dialog will appear prompting the user if they want to store the present system state to file.
