WG10 Future Work #5940
Multiple LNodes implemented by same LN
0%
TR IEC 61850-90-30
Description
From IOP discussions:
"When a specification defines multiple LNodes in the specification which are implemented by the same LN in a device, there is no standard way to represent this mapping. Part 6 is currently not clearly stating if multiple LNodes can be mapped to same LN or not
A good example for this need is the PTRC which could be define during specification into each protection function, and finally only one instance is defined in the protection device.
This could have an impact on functional naming if one LN implements multiple LNode"
But this is currently forbidden in part 6:
ยง9.2.6: "Therefore, the combination of iedName, ldInst, prefix, lnClass and lnInst shall be unique within all substation sections if iedName is not None."
Proposal descriptions
This problem is addressed in 6-100 by changing cardinality and introducing LNodeSpecNaming.
To be implemented in Edition 3 of part 6.
