Integrated Topology Processing: Saving the Planning Case

Concept Link IconSee Also

 

Integrated Topology Processing allows you to save the Consolidated Representation of the Full-Topology Model as a traditional Planning Case (bus/branch model), in any of the formats supported by Simulator.

Although the saved case can be reopened in Simulator as a regular case, the user should note that the topology of this case will depend on the statuses of the breakers in the Full-Topology Model. If the statuses of the switching devices in the Full-Topology Model are continuously changing as is the case when the case comes from a real-time Retriever implementation, then the topology of the saved cases will be slightly different minute to minute.

The saving tool is available on the Topology Processing Dialog in the Consolidated Case Save Options section.

Open Non-Energized Branches

If the terminal buses of a transmission line or transformer are not energized, then assume the element is open.

Convert Shunts to Blocks

Some systems have several shunts in a superbus, and some formats support only one shunt per bus. This option allows modeling those shunts as an aggregate device.

Do not save contingencies (will make smallest case size)

Use this option if contingency analysis will not take place on the saved case.

Save contingencies (must preserve all elements including breakers)

All the contingencies, the contingency actions, and all the switching devices included in contingency actions will be preserved and saved in the consolidated case. It makes a big difference to perform a Breaker-to-Device Contingency Conversion before saving the case. Usually most of the breaker contingencies can be converted to device contingencies requiring just a small number of breakers to be preserved in the case.  Some planning tools have limitations regarding the number of low impedance branches that can be modeled and will not be able to read and solve the Planning Case if it contains a large number of switching devices.
