Opening a Simulation Case

The most common first step in using Simulator is to open a case. When a case is opened, any associated oneline files are also opened. To open a case, either select it from the list of recently opened cases in the file menu or

• Select Open Case from the File menu to display the Open Dialog.
• In the Type of Files box, select the desired file type. By default, the PowerWorld Binary type is selected (*.PWB). The PowerWorld Binary is the preferred file type, providing the most comprehensive power system information along with the smallest size and quickest load time. Other file types include the PowerWorld Case type, PowerWorld Auxiliary file, PTI Raw Data formats, GE EPC text format, and IEEE Common Format. Please see Case Formats for more details.
• In the list of cases, click on the desired case.
• Click OK.

When opening an existing Simulator case, you may see one or more oneline diagrams pop up. When opening a power flow case created with another program, a oneline may not be available. However, you can easily create a oneline for such a case using the Edit Mode.

The Bus Records table of the Model Explorer will be displayed by default when opening a case that does not have any associated oneline diagrams.

If you are in the Edit Mode, you can modify the case. See Edit Mode Overview for details.

If the case has validation errors, the mode is immediately switched to Edit Mode. You must correct the validation errors shown in the message log before you can use the Run Mode to solve the case.
