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/>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/>

Terminal
Class  
Name: Terminal
The terminals associated with the topological node. This can be used as an alternative to the connectivity node path to terminal, thus making it unneccesary to model connectivity nodes in some cases. Note that if connectivity nodes are in the model, this association would probably not be used as an input specification.

BusNameMarker
Class  
Name: BusNameMarker
BusnameMarkers that may refer to a pre defined TopologicalNode.
Name: TopologicalNode
A user defined topological node that was originally defined in a planning model not yet having topology described by ConnectivityNodes. Once ConnectivityNodes has been created they may linked to user defined ToplogicalNdes using BusNameMarkers.

ConnectivityNode
Class  
Name: ConnectivityNodes
The connectivity nodes combine together to form this topological node. May depend on the current state of switches in the network.
Name: TopologicalNode
The topological node to which this connectivity node is assigned. May depend on the current state of switches in the network.

TopologicalIsland
Class  
Name: AngleRefTopologicalIsland
The island for which the node is an angle reference. Normally there is one angle reference node for each island.
Name: AngleRefTopologicalNode
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.
