To open the Topology Processing Dialog select Topology Processing found on the Add Ons ribbon tab in the Topology Processing ribbon group. This dialog includes options to solve the Power Flow Using Topology Processing, perform Contingency Analysis Using Topology Processing, and for Saving the Consolidated Case.
Power Flow Solution Options
Use Consolidation (This is a Full-Topology Model)
This option is used for all Simulator applications: power flow, contingency analysis, sensitivity calculations, etc. This option should ALWAYS be checked for real-time cases, while it should be unchecked for planning cases. If a full-topology model was read and this option is not checked, the power flow will try to solve the model without removing the switching devices resulting in a very large ill-conditioned Jacobian. This option is also found on the Power Flow Solution Common Options page of the Simulator Options dialog.
Breaker Options Added in version 20
Click the Update Allow Open or Close Breakers button to set the Allow Open or Close Breakers field for branches based on the current power flow case. When this field is set to NO, a switching device is not allowed to be selected when using processes that automatically determine breakers and other switching devices that operate to isolate or energize a device. See the Update Allow Open or Close Breakers topic for more information on how this field is set.
Contingency Analysis
These options are shown on this dialog for informational purposes only. These can be accessed and set from the Contingency Analysis dialog on the Options tab and Modeling sub-tab. These options are described in more detail in the Contingency Analysis Using Topology Processing topic.
Consolidated Case Save Options
These options allow the saving of the consolidated representation as a traditional planning case. More detail about these options is provided in the Saving the Planning Case topic.
Options found on the Primary Bus Mapping tab are described in the Primary Bus Mapping topic.
