SvInjection

The SvInjection is reporting the calculated bus injection minus the sum of the terminal flows.

-The angle reference node is the TopologicalNode to which a synchronous machine is connected and referenced from TopologicalIsland.AngleRefTopologicalNode.

-The TopologicalIsland-s for a merged model which are defined in the state variables instance file for the merged model are created with the solving on the power flow of the merged model, i.e. there are no TopologicalIsland-s defined per MAS in a merged model. In case a solved model is exchanged for a single MAS the state variables profile must include at least one instance of TopologicalIsland.

Native Members

TopologicalNode

Topology

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).
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".
