In order to perform numerical solutions using Integrated Topology Processing, Simulator does the following:
Consolidates the system relocating the devices and removing not needed breakers and non primary buses.
Performs the numerical calculation.
De-consolidates the system by restoring breakers and relocating the devices to their original buses. This step also maps the values of the primary buses to all the buses in the superbus.
This is transparent to the user, who only needs to tell Simulator to use consolidation. The option that needs to be set to use consolidation is found on the Topology Processing Dialog and also on the Power Flow Solution page of the Simulator Options dialog.
