IEC61850-7-5 #6726
New LN of group L (as "LTED") to represent the dynamic topology of the substation.
0%
Description
Details:
Some functions need to know the current topology of the substation.
For doing that,
- 1 LN LTED is instanciated for each feeder connected to the busbar and for each busbar segment.
- ElNodeRef indicates the reference number of the electrical node of the busbar to which the LN is associated, calculated on the base of its actual topology (disconnector and circuit breaker position).
- ElNodeNum indicates the total number of electrical nodes into which a busbar is splitted on the base of its actual topology (disconnector and circuit breaker position).
- ElNodeVTRef is used by the LD publishing voltage information (SV or PhV). Only one LD can adopt the number of the Electrical Node. This LD published the busbar voltage reference for corresponding electrical node, indicating if this voltage is to be used as voltage reference for an Electrical Node. If not, its value is set to zero.
Argument: Needed for some PACS functions.
