Short Proposal:

Describe analog I/O similar to LDPI/LDPO for digital I/O.

Standard(s):

IEC TR 61850-90-29


Description

Need to have a new DO to identify the physical terminal allocation of a TVTR and TCTR.
We want to have a DO that allows to identify that a LN TVTR and a LN TCTR. This new DO will describe the physical VT / CT interface, as done in LPDI / LPDO for digital I/O.
Helpful for maintenance and exploitation of the system.


Proposal descriptions

Routed to task force 90-29 "Physical I/O description". Will be discussed after circulation of the TR 90-29.

Meeting 2020-12-17:
The idea is to describe in the model the analog I/O similar to the LDPI/LPDO for digital I/O. To check with the task force in charge of the physical I/O description data model. It seems the analog I/O modelled in this task force is only related to mA inputs for temperature and this kind of things.
A dedicated logical node or a new DO inside TVTR and TCTR.
UF to check with the task force in charge of physiscal I/O description.

2021-03-02: DPL.location could be used for identifying the bay level, but not for physical connection

Updated by Carlos Rodriguez del Castillo about 2 months ago

Clarification needed: "is it enough to put inside substation section instead of a DO (through data model)?"
TF group does not think that every SCL feature should be mapped into a DO, online model.

Precision about the use case : to be able to indicate the link between the IED and the physical terminal of Instrument Transformer or bay terminal block. The use of boundary LN, in a similar approach than digital inputs / outputs with LPDI / LPDO, could be a solution. This issue was sent to Physical Ressources TF (Dehui Chen) on 2021-03-10, proposal to discuss these new issues after circulation of the TR 90-29.
