A SuperBus in the Full-Topology Model is a group of buses connected through CLOSED switching devices or other CLOSED very low-impedance branch devices. All the buses in a Superbus have the same voltage phasor, i.e., they correspond to the same electric point. As the status of switching devices change, superbuses change correspondingly, sometimes resulting in superbus merging or splitting.
Superbuses are set automatically when the case is read from the binary or aux file and they are updated at the beginning of a power flow solution or sensitivity calculation to capture possible changes in the status of switching devices. The details of the Superbus records is available in the Model Explorer under Solution Details > Superbuses.
Consolidation of superbuses iteratively remove superbuses that contain ONLY switching devices that are connected to other superbus only by open switching devices. These are of no significance so merging into a superbus removes the clutter.
A superbus in the Full-Topology Model would correspond to a bus in the electrically equivalent bus/branch planning case.
Each Superbus in a system belongs to only one Subnet.
