For a detailed substation model a topological node is a set of connectivity nodes that, in the current network state, are connected together through any type of closed switches, including  jumpers. Topological nodes change as the current network state changes (i.e., switches, breakers, etc. change state).<br /></p><p>For a planning model, switch statuses are not used to form topological nodes. Instead they are manually created or deleted in a model builder tool. Topological nodes maintained this way are also called "busses".<br /></p>

TopologicalIsland
Class  
Name: AngleRef_TopologicalIsland
The island for which the node is an angle reference. Normally there is one angle reference node for each island.
Name: AngleRef_TopologicalNode
The angle reference for the island. Normally there is one TopologicalNode that is selected as the angle reference for each island. Other reference schemes exist, so the association is typically optional.
