An electrically connected subset of the network. Topological islands can change as the current network state changes: e.g. due to <br/>- disconnect switches or breakers change state in a SCADA/EMS<br/>- manual creation, change or deletion of topological nodes in a planning tool.<br/><br/>

TopologicalNode
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.
