Description

Feeder:
How to modelize a feeder as a collection of equipments powered by the same Feeder-switch.
It is a notion derived from connectivity, Swicthes positions, on which different set of rules (may differ from on utility to an other) are applied to define the spreading part of network concerned.

This is typical to Distribution networks, where networks are managed as radial.
  • Usually one Switch feeds a network this network part.
  • Open Switches serve as borderline with other network parts (used to rescue when a feeder-switch is down).
  • These 2 special points of the network part should be clearly identified and indicate what they are borders to.
  • To satisfy deferent detailed level applications, expressing the composition of the FEEDER should be possible at 2 detail-levels: Containers and elementary equipments.
    • Containers: Substation,Line, VoltageLevel for undetailed definition.
    • ConductingEquipments or ConnectivityNodes for detailed definition.
  • Feeders might be hierarchically subdivided (for Exemple a MV-Feeder, feeds/includes several LV subnetworks ).

Proposed Solution

Resurect the Circuit class (or name it as Feeder).
Define associations to its contents:
1- EquipmentContainer<-->Circuit
2- ConductingEquipment<---->Circuit

Define associations to its limits:
3- FeedingNodes: Circuit <---> Terminal. Identify the Terminal(s) of the ConductingEquipment considered as Incomming point of the feeder. (Might the feeder-switch, or first ACLineSegment connected to it).
4- CircuitEnds: Circuit <----> Terminal
Identify the Terminal(s) of open switches that are shared by 2 Circuits.

Define association to its subdivisions:
5- Circuit(Including) <----> ("Included in") Circuit

Decision

19-Sep-2024 Joint TF Hybrid Meetings - Minneapolis:

Reviewed. Decision made to assign to Alex Anderson. His work associated with Issue #6924 addresses this as part of that solution. As a result we agreed to close this one out.
