Other Contingency Actions
By clicking the Other > button on the Contingency Analysis dialog, you have access to several
actions.
Delete All Contingencies
Click this to delete all the contingencies presently stored in memory.
Clear All Contingency Results
Click this to clear all the results of the contingencies from memory. This will not delete the
contingencies.
Set As Reference
Click this to set the case presently in memory as the Reference State for contingency analysis. For
more information on the reference state, see Contingency Case References.
Restore Reference
Click this to set the state of the present power system case back to the contingency analysis
reference state. For more information on the reference state, see Contingency Case References.
Convert to Device Contingencies
This command is intended for use with full topology models, where breakers and disconnects are
defined in addition to generators, loads, transmission lines, etc. This function would have no affect
on a traditional planning model representation in which no breakers or disconnects are explicitly
defined.
The purpose of this option is to allow the user to take a contingency set that is defined with outages
of breakers and disconnects in a full topology model and convert them to outages of the traditional
planning model elements, such as generators, loads, transmission lines, etc. This would be used in
conjunction with the ability to save a full topology model as a consolidated model. A consolidated
model reduces the full model down to a traditional planning model by examining the breaker and
disconnect statuses and reducing the system down by consolidating breakers and disconnects that
are in service. The resulting model is a smaller model with the traditional planning elements
represented, but breakers and disconnects have been removed and nodes aggregated into bus
representations. This function will also take the breaker and disconnect statuses and convert them
into contingencies of the planning model devices affected by opening the original breakers or
disconnects. Thus, you could create a contingency that is defined for the consolidated model and
can be run on the consolidated model with the same results as if the original contingency set is run
on the full topology model.
The contingency set generated depends on the statuses of the breakers and disconnects, and the
contingencies created will be different for the different statuses of breakers and disconnects in the
full topology model.
Combined Tables
Contingency Violation Matrices
Clicking Process Contingency Results will go through the existing contingency analysis tool
results and build tables showing the limit violation values for all violated lines, interfaces, and buses
and the contingencies for which each element is violated. Upon opening, it is possible to limit
processing to branches, buses, and/or interfaces. Also, you can specify whether to display
percentages or actual flows in the resulting tables.
